"Nucleotide Excision Repair (NER) removes a variety of helix-distorting lesions from DNA. It has two sub-pathways, the global genome (gg) NER and the transcription-coupled repair (TCR). TCR is triggered when a RNA polymerase, translocating along the transcribed strand, is arrested at a lesion or unusual structure in the DNA. TCR is dedicated to target and repair the transcribed strand of an active gene."

"Complex chromosome rearrangement of 6p25.3->p23 and 12q24.32->qter in a child with moyamoya.",
"Routine karyotype demonstrated extra chromosomal material on 6p. Single nucleotide polymorphism microarray revealed a previously unreported complex de novo genetic rearrangement involving subtelomeric segments on chromosomes 6p and 12q.",
"In terms of the genetics, recent literature suggests a low penetrance autosomal dominant or polygenic mode of transmission involving chromosomes 3, 6, 8, 12, and 17 for familial MMD. ",
"Furthermore, the current literature on familial MMD has pointed to a low penetrance autosomal dominant or polygenic mode of transmittance at loci on chromosomes 3, 6, 8, 12, and 17.",
"Here, we report on three unrelated families affected with an X-linked moyamoya syndrome characterized by the association of a moyamoya angiopathy, short stature, and a stereotyped facial dysmorphism. ",
"We show that this syndromic moyamoya is caused by Xq28 deletions removing MTCP1/MTCP1NB and BRCC3. ",
"A genome-wide association study of 785,720 single-nucleotide polymorphisms (SNPs) was performed, comparing 72 Japanese MMD patients with 45 Japanese controls and resulting in a strong association of chromosome 17q25-ter with MMD risk. This result was further confirmed by a locus-specific association study using 335 SNPs in the 17q25-ter region. ",
"Investigations included neuroimaging, cardiologic and ophthalmologic evaluation, hormonal testing, hemoglobin electrophoresis, chromosomal karyotyping, muscle biopsy for morphology, immunohistochemistry and enzyme assays, mtDNA mutation screening, and haplotype analysis of 2 loci previously linked to moyamoya, on chromosomes 10 (ACTA2) and 17.",
"These data strongly suggest that this family is affected by a hereditary moyamoya multisystem disorder with X-linked recessive pattern of inheritance.",
"Her features were consistent with TS and chromosome analysis revealed mosaicism in which 17% of the cells showed a pseudoisodicentric Y chromosome: 45,X (25)/46,X psu idic (Y)(11.2) (5). ",
"The small number of cases does not allow detailed analysis other than noting patient age (two older than 40 years), karyotype (two others associated with isochrome Xq), and associated cardiac risk factors (one with BAV).",
" Studies have shown a possible genetic association of MMD linked to chromosome 17 in Japanese cases as well as in cases found in other demographics. ",
"The gene responsible for NF1 is located on the chromosome region 17q11.2 and for familial moyamoya disease on chromosome 17q25. ",

"[Molecular screening for moyamoya disease by use of expressed sequence tag on chromosome 3p].",
" To identify the expressed sequence tags (ESTs) with monoallelic expressions on chromosome 3, we used mouse A9 hybrid cells having human chromosome 3. Two ESTs showed only maternal expression in mouse A9 hybrid cells, and four showed non-expression in the lymphocytes derived from moyamoya patients. ",
"A novel susceptibility locus for moyamoya disease on chromosome 8q23.",
"Previous linkage studies have indicated that susceptibility loci for the disease are located on chromosomes 3p, 6q, and 17q. In the present study, we searched for loci linked to the disease in 12 Japanese families using 428 microsatellite markers and found significant evidence for linkage to 8q23 [maximum LOD score (MLS) of 3.6] and suggestive evidence for linkage to 12p12 (MLS=2.3). ",
"Considering the function, we selected nine genes as candidates from a total of 65 genes identified in the 9-cM region of D17S785-D17S836 in chromosome 17q25, and performed sequence analysis on the DNA samples obtained from a pedigree of familial moyamoya disease, which showed a complete linkage to the region by a haplotype analysis.

"CONCLUSIONS: A gene for familial moyamoya disease is located on chromosome 17q25.",
"Recent genetic studies suggest some responsible genetic foci in chromosomes 3, 6 and 17.",
"To further specify the genetic component of moyamoya disease, a linkage study of moyamoya disease using markers on chromosome 6, where the HLA gene is located, was performed. ",
"Mapping of a familial moyamoya disease gene to chromosome 3p24.2-p26.",
"A linkage was found between the disease and markers located at 3p24.2-26.",
"We postulate that a protein encoded on chromosome 21 may be related to the pathogenesis of moyamoya disease. ",

"The genetic basis of tuberous sclerosis has been attributed to mutations in one of two unlinked genes, TSC1 and TSC2. The functions of the TSC1 and TSC2 gene products, hamartin and tuberin, respectively, have remained ill defined until recently. Genetic, biochemical, and biologic analyses have highlighted their role as negative regulators of the mTOR signaling pathway. Tuberin, serving as a substrate of AKT and AMPK, mediates mTOR activity by coordinating inputs from growth factors and energy availability in the control of cell growth, proliferation, and survival. Emerging evidence also suggests that the TSC 1/2 complex may play a role in modulating the activity of beta-catenin and TGFbeta. These findings provide novel functional links between the TSC genes and other tumor suppressors.",
"The genetic basis of this disease has been attributed to mutations in one of two unlinked genes, TSC1 and TSC2.",
"We previously found TSC2 loss of heterozygosity in 7 of 13 (54%) of angiomyolipomas from sporadic LAM patients, suggesting that LAM and TSC could have a common genetic basis. In this study, we report the identification of somatic TSC2 mutations in five of seven angiomyolipomas from sporadic LAM patients. Our data demonstrate that somatic mutations in the TSC2 gene occur in the angiomyolipomas and pulmonary LAM cells of women with sporadic LAM, strongly supporting a direct role of TSC2 in the pathogenesis of this disease. The study of hereditary tumor syndromes has laid a solid foundation toward understanding the genetic basis of cancer."

"Computational methods attempting to identify instances of cis-regulatory modules (CRMs) in the genome face a challenging problem of searching for potentially interacting transcription factor binding sites while knowledge of the specific interactions involved remains limited. When discriminating CRMs from non-coding regions, those methods considering evolutionary conservation have a stronger predictive power than methods designed to be run on a single genome. Furthermore, most methods appear to be sensitive to the composition and structure of the genome to which they are applied. CisMiner allows to perform a blind search of CRMs without any prior information about target CRMs nor limitation in the number of motifs.",
"The optimal choice of method varies depending on species and composition of the sequences in question. When discriminating CRMs from non-coding regions, those methods considering evolutionary conservation have a stronger predictive power than methods designed to be run on a single genome. Different CRM representations and search strategies rely on different CRM properties, and different methods can complement one another. For example, some favour homotypical clusters of binding sites, while others perform best on short CRMs. Furthermore, most methods appear to be sensitive to the composition and structure of the genome to which they are applied. A statistical model to describe the underlying cluster structure as well as individual motif conservation has also been proposed, accompanied with a Monte Carlo motif screening strategy for predicting novel regulatory modules in upstream sequences of coregulated genes."

"Several tools allow to detect significant co-occurrences of closely located binding sites (cis-regulatory modules, CRMs). However, these tools present at least one of the following limitations: 1) scope limited to promoter or conserved regions of the genome; 2) do not allow to identify combinations involving more than two motifs; 3) require prior information about target motifs.",
"In this work we present CisMiner, a novel methodology to detect putative CRMs by means of a fuzzy itemset mining approach able to operate at genome-wide scale. CisMiner allows to perform a blind search of CRMs without any prior information about target CRMs nor limitation in the number of motifs. CisMiner tackles the combinatorial complexity of genome-wide cis-regulatory module extraction using a natural representation of motif combinations as itemsets and applying the Top-Down Fuzzy Frequent- Pattern Tree algorithm to identify significant itemsets.",

"The most prevalent antibody numbering systems are the Kabat system, the Chothia system as well as the IMGT numbering system."
] | [] | [
"IMGT is a high quality integrated knowledge resource specialized in immunoglobulins (IG), T cell receptors (TR), major histocompatibility complex (MHC) of human and other vertebrates, and related proteins of the immune system (RPI) of any species which belong to the immunoglobulin superfamily (IgSF) and to the MHC superfamily (MhcSF). IMGT consists of five databases, ten on-line tools and more than 8,000 HTML pages of Web resources. IMGT provides a common access to standardized data from genome, genetics, proteome and three-dimensional structures. ",
"amino acid positions according to the IMGT unique numbering (NUMEROTATION) that are used in IMGT/3Dstructure-DB cards, results of contact analysis and renumbered flat files.",
"Standardized sequence and structure analysis of antibody using IMGT(®) databases and tools allows one to bridge, for the first time, the gap between antibody sequences and three-dimensional (3D) structures. This is achieved through the IMGT Scientific chart rules, based on the IMGT-ONTOLOGY concepts of classification (IMGT gene and allele nomenclature), description (IMGT standardized labels), and numerotation (IMGT unique numbering and IMGT Colliers de Perles). ",
"Kabat Database was initially started in 1970 to determine the combining site of antibodies based on the available amino acid sequences at that time.",
"comparative analysis of the main-chain conformation of the L1, L2, L3, H1 and H2 hypervariable regions in 17 immunoglobulin structures that have been accurately determined at high resolution is described. This involves 79 hypervariable regions in all. We also analysed a part of the H3 region in 12 of the 15 VH domains considered here. On the basis of the residues at key sites the 79 hypervariable regions can be assigned to one of 18 different canonical structures. We show that 71 of these hypervariable regions have a conformation that is very close to what can be defined as a \"standard\" conformation of each canonical structure. These standard conformations are described in detail. The other eight hypervariable regions have small deviations from the standard conformations that, in six cases, involve only the rotation of a single peptide group",
"the basis of comparative studies of known antibody structures and sequences it has been argued that there is a small repertoire of main-chain conformations for at least five of the six hypervariable regions of antibodies, and that the particular conformation adopted is determined by a few key conserved residues."

"Mir155 was bound by Th17 cell transcription factors and was highly expressed during Th17 cell differentiation. miR-155-deficient Th17 and T regulatory (Treg) cells expressed increased amounts of Jarid2, a DNA-binding protein that recruits the Polycomb Repressive Complex 2 (PRC2) to chromatin. PRC2 binding to chromatin and H3K27 histone methylation was increased in miR-155-deficient cells, coinciding with failure to express Il22, Il10, Il9, and Atf3. Defects in Th17 cell cytokine expression and Treg cell homeostasis in the absence of Mir155 could be partially suppressed by Jarid2 deletion.

"Downregulation of FGFR2b-signaling by isotretinoin explains its therapeutic effect in acne. Downregulation of FGFR2b-signaling during the first trimester of pregnancy disturbs branched morphogenesis and explains retinoid embryotoxicity.",
"The isotretinoin, a 13-cis-retinoic acid, has revolutionized the management of severe treatment-resistant acne and it has been widely used for a range of dermatological conditions, in 90% of the time in young women between 13 and 45 years of age. This agent has severe teratogenic effects, as serious craniofacial, cardiovascular, thymic and central nervous system malformations.",
"malformations is 3-5%, but it increases to almost 30% in women exposed to isotretinoin during the first trimester of pregnancy.

"90 women who became pregnant while on the drug, 76 terminated the pregnancy (84%), three had a spontaneous abortion (3%), two had trauma during delivery resulting in neonatal deaths (2%) and nine had a live birth (10%). Among the live births, only one had a congenital anomaly of the face and neck (11%).",
"elective abortion rates were also much higher in our study.",
"Topical antibiotics, isotretinoin or systemic antibiotics are usually used for acne therapy. However, isotretinoin cannot be used during pregnancy because it can cause significant birth defects while systemic antibiotics can have adverse side effects such as gastrointestinal irritation, photosensitivity and tetracycline sensitivity.",
"Isotretinoin has been used to treat acne since 1982. Its current indications in the package insert are limited and many physicians still feel uncomfortable prescribing it because of its side effects.",

"Twelve 60-day-old female Mus musculus were divided into two groups on the 7th day of pregnancy: treated group--1 mg isotretinoin per kg body weight, dissolved in vegetable oil, was administered from the 7th to the 13th day of pregnancy; control group--vegetable oil in equivalent volume was administered orally for the same period. On the 16th day of pregnancy, the females were sacrificed, the fetuses were removed and their heads amputated.",
"The results showed that both groups had closed palates with no reminiscence of epithelial cells; however, the first molar germs of the isotretinoin-treated animals showed delayed development compared to the control animals.",
"Isotretinoin (13-cis-RA) is teratogenic in all species examined; based on administered dose, humans appear most sensitive, followed by (in order or decreasing sensitivity) monkey, rabbit, hamster, mouse, and rat.",
"Based on embryonic delivered dose, we suggest that 13-cis-RA is an equipotent teratogen in hamster and rabbit.",
"its safety in humans is occasionally questioned because oral ingestion of retinoids at therapeutic levels is known to entail teratogenic risks.",
"topical tretinoin is not a potential human developmental toxicant.",
"Teratogenicity of vitamin A was firstly detected in experimental animals in 1953. Nearly 30 years later, teratogenicity of vitamin A analogue-isotretinoin was reported in humans. Isotretinoin induces serious birth defects of craniofacial and central nervous system, cardiovascular system and thymic malformations--in about 25% of babies exposed during the first trimester of their prenatal development.",
"high vitamin A intake in pregnant woman: Women who use daily vitamin A supplements during early pregnancy have approximately a two-fold increased risk of giving birth to a malformed baby.",
"Vitamin A started to affect development between doses 0.3-0.3 microm [corrected] per embryo. Malformations of head, extremities and heart were detected similarly like in laboratory mammals and in man",
"the minimal embryotoxic doses of vitamin A in mammals were estimated to be between 0.1-1 mg/kg of maternal weight",
"Human epidemiological studies have proved teratogenicity of vitamin A after daily doses 25,000 i.u.-8.3 mg (0.13 mg/kg)- and reduction of its maximum intake has been recommended to 10,000 i.u. per day (0.05 mg/kg). The results about teratogenicity of vitamin A achieved in the chick embryo are in agreement with such a recommendation. Intake of vitamin A in the food is sufficient for pregnant woman in common Czech population. Therefore, an artificial supplementation of vitamin A brings risk of overdosage. If supplementation by vitamin A is unavoidable during pregnancy, B-carotene should be preferred.",
"a teratogenic dosing regimen with 13-cis-RA [Hummler et al. (1994) Teratology 50:184-193].",
"plasma AUC values of all-trans-RA were 2- to 7-fold higher after all-trans-RA administration (present study) than after dosing with the teratogenic dose of 13-cis-RA. These results strengthen our recent suggestion that the teratogenic effects induced in cynomolgus monkeys by 13-cis-RA treatment cannot solely result from the action of all-trans-RA, but may involve 13-cis-RA and 13-cis-4-oxo-RA, which could act directly or function as transport vehicle.",
"VITA, among others, is involved in the process of morphogenesis. In contrast, synthetic derivatives of VITA, specifically Tigasone (etretinate, TIG) and Roaccutane (isotretinoin, ROA), are regarded as major teratogens.",
"A biphasic maximal inhibition was present at 1 microM concentrations when the retinoids VITA, TIG and ROA were added for 16 h (52, 58 and 57%, respectively; P < 0.01 by one-way analysis of variance). In contrast, the addition of the three retinoids at 1 microM concentrations for 16 h had no significant effect on HCG secretion by placental explants of 11-13 weeks gestational age.",
"Inhibition of HCG secretion by retinoids may contribute either directly or indirectly to their teratogenicity.",
"Isotretinoin is a potent retinoic acid used in the treatment of skin disorders. Though very effective, it is teratogenic if administered during pregnancy, and its teratogenic effect may be related to the normal activity of retinoids as signalling molecules in the embryo.",

"Proliferation in heart tissue of whole embryo cultures was inhibited in medium with 10(-6) M isotretinoin to 62% of the control level in myocardium.",
"The results suggest multiple effects of retinoids on growth, morphogenesis, and differentiation of early cardiac tissue, and are discussed in relation to the potential role of retinoids in early embryogenesis.",
"Oral administration of 400 mg/kg of 13-cis retinoic acid to 9 day pregnant mice gives rise to important maxillofacial malformations. The first manifestation of teratogenic effect is an increase of density of cell death arising in the dorsal part of the first two branchial arches at day 9.5. These two arches become hypoplastic at days 10 and 11, and the preskeletal anlagen appear too late in comparison to control embryos. Meckel's cartilage is too curvilinear and medially situated. Pre-ossicular and pre-mandibular blastemata develop with spatial distortions which are well analyzable at days 16 and 17",
"Isotretinoin (13-cis-retinoic acid, Accutane) increases the risk of major congenital malformations in infants exposed to isotretinoin during pregnancy. However, there have been no epidemiologic reports to date on the effect of a subsequent pregnancy after discontinuation of isotretinoin.",
"analysis of pregnancy case reports from patients in whom conception occurred after isotretinoin treatment had been discontinued",
"spontaneous and missed abortions from all pregnancies was 9.1% (eight patients), and the incidence rate of congenital malformation among the live births was 5.0% (four patients).",
"were not significantly different from the rates reported for women of reproductive age in the general population. In addition, the malformations reported were not characteristic of retinoic acid-induced congenital anomalies.",
"Keratolenticular dysgenesis (Peters' anomaly) was induced in mice by exposure to the human teratogens, ethanol or 13-cis retinoic acid (isotretinoin, Accutane). Acute teratogen exposure on the seventh day of gestation (corresponding to the third week of human gestation) resulted in an eye malformation incidence of 46% to 100% in day 14 fetuses",
"This secondary effect on neural crest derivatives is exhibited in the adult animals as corneal opacities associated with defects in Descemet's membrane and endothelium, and anterior polar cataracts.",
"13-cis-retinoic acid (13-cis-RA, or isotretinoin) is responsible for various craniofacial malformations in the rodent and human embryo.",
"In whole embryo culture, 13-cis-RA caused significant overall embryonic growth retardation, especially in the primary and secondary palatal processes.",
"subsequent cell growth was decreased at concentrations of 13-cis-RA greater than 1 X 10(-5) M. After a 40-hr treatment period, labeling indices in retinoid-treated cells were significantly lower than control values (25% compared with 40%). Retinoic acid also caused a significant, concentration-dependent decrease in 3H-thymidine incorporation. The inhibitory effect of 13-cis-RA on proliferation of oral-nasal mesenchymal cells appears to be related to the production of craniofacial malformations.",
"Reports of adverse human pregnancy outcomes including cleft palate have increased as the clinical use of isotretinoin (13-cis-retinoic acid) and other retinoic acid (RA) derivatives have increased, but the mechanisms by which their effects are exerted are not understood.",
"In shelves exposed to EGF and trans-RA early in their development, DNA synthesis appears to terminate prematurely as compared to shelves cultured in control media, and this effect is accompanied by excessive mesenchymal extracellular space expansion. Exposure of shelves to EGF alone is sufficient to block degeneration and induce hyperplasia of the medial epithelial cells but does not induce other ultrastructural changes seen with both EGF and RA. The observed alterations in medial cell morphology could interfere with adhesion of the palatal shelves and may play a role in retinoid-induced cleft palate in the human embryo.",
"Recent clinical observations strongly suggest that isotretinoin [13-cis-retinoic acid (cis RA)] is a human teratogen causing primarily heart and craniofacial malformations including ear and palatal defects.",
"Our results demonstrate that labeled cis RA enters the tissues of the embryo both in vivo and in vitro. Cis RA inhibited proliferation of the frontonasal mesenchyme cells in primary culture with 31% inhibition occurring at 2 X 10(-5) M cis RA.",
"Retinoic acid, an analogue of vitamin A, is known to be teratogenic in laboratory animals and has recently been implicated in a few clinical case reports. To study the human teratogenicity of this agent, we investigated 154 human pregnancies with fetal exposure to isotretinoin, a retinoid prescribed for severe recalcitrant cystic acne. The outcomes were 95 elective abortions, 26 infants without major malformations, 12 spontaneous abortions, and 21 malformed infants. A subset of 36 of the 154 pregnancies was observed prospectively.",
"Exposure to isotretinoin was associated with an unusually high relative risk for a group of selected major malformations (relative risk = 25.6; 95 per cent confidence interval, 11.4 to 57.5).",
"It is possible that a major mechanism of isotretinoin teratogenesis is a deleterious effect on cephalic neural-crest cell activity that results in the observed craniofacial, cardiac, and thymic malformations."

"The p53 tumour suppressor protein is tightly controlled by the E3 ubiquitin ligase, mouse double minute 2 (MDM2).

"p53 levels and activity are controlled in large part through regulated ubiquitination and subsequent destruction by the 26S proteasome.

Aside from its ubiquitin ligase function, Mdm2 has been believed to be capable of suppressing p53's transcriptional activity by binding with and masking the transactivation domain of p53.",

This dogma was recently challenged by data generated from knockin mice in which Mdm2's RING E3 ubiquitin ligase activity was abrogated by a single point mutation. The RING mutant Mdm2 is fully capable of binding with p53, yet cannot suppress p53 activity, suggesting that Mdm2 cannot block p53 by binding alone, without ubiquitination.",

"The p53 tumor suppressor protein has a major role in protecting genome integrity. Under normal circumstances Mdmx and Mdm2 control the activity of p53. Both proteins inhibit the transcriptional regulation by p53, while Mdm2 also functions as an E3 ubiquitin ligase to target both p53 and Mdmx for proteasomal degradation. ",
"p53 is a critical coordinator of a wide range of stress responses. To facilitate a rapid response to stress, p53 is produced constitutively but is negatively regulated by MDM2. MDM2 can inhibit p53 in multiple independent ways: by binding to its transcription activation domain, inhibiting p53 acetylation, promoting nuclear export, and probably most importantly by promoting proteasomal degradation of p53. The latter is achieved via MDM2's E3 ubiquitin ligase activity harbored within the MDM2 RING finger domain.",

Recent studies have shown, however, that the ring-finger domain (RFD) of MDM2, where the ubiquitin E3 ligase activity resides, is necessary but not sufficient for p53 ubiquitination, suggesting that an additional activity of MDM2 might be required.",
"The Mdm2 proto-oncogene is amplified and over-expressed in a variety of tumors. One of the major functions of Mdm2 described to date is its ability to modulate the levels and activity of the tumor suppressor protein p53.

Therefore, identification of novel molecules involved in this regulatory loop is necessary for understanding the dynamic regulation of p53 and treatment of human diseases.

Many compounds capable of inhibiting DNA topoisomerase II are DNA intercalators.",
"The pyridoacridines' ability to inhibit TOPO II-mediated decatenation of kDNA correlated with their cytotoxic potencies and their ability to intercalate into calf thymus DNA. These results suggest that disruption of the function of TOPO II, subsequent to intercalation, is a probable mechanism by which pyridoacridines inhibit the proliferation of HCT cells.",
"Evidence for DNA intercalation by AD41 is provided by the observation that the drug introduces positive supercoils into covalently closed plasmid DNA.

"Therefore, to more fully analyze structure-function relationships and the role of DNA binding in the action of m-AMSA, we analyzed a series of derivatives for the ability to enhance DNA cleavage mediated by human topoisomerase IIα and topoisomerase IIβ and to intercalate DNA. Results indicate that the 3'-methoxy (m-AMSA) positively affects drug function, potentially by restricting the rotation of the headgroup in a favorable orientation."

"Functional studies employing antagomirs have identified contributions from miR-34a and miR-132 to seizure-induced neuronal death whereas silencing miR-134 potently reduced status epilepticus, seizure-damage and the later occurrence of spontaneous seizures. Efforts to identify the in vivo target(s) of epilepsy-regulated miRNAs, is now a priority. Last, miRNA are stable, information-carrying (paracrine) signals. Profiling miRNA in biofluids may represent a novel source of disease biomarkers in epilepsy.",
"Inflammation, stress signalling and neuronal excitation are among the pathways most impacted.",
"Herpes simplex virus (HSV) causes a chronic immuno-inflammatory response in the eye that may result in corneal neovascularization during blinding immunopathological lesion stromal keratitis (SK). miR-132 is a highly conserved miRNA that is induced in endothelial cells in response to growth factors, such as vascular endothelial growth factor (VEGF).",
"miR-132 expression was up-regulated (10- to 20-fold) after ocular infection with HSV, an event that involved the production of both VEGF-A and IL-17.",
"The anti-angiogenic effect of antagomir-132 was reflected by a reduction in angiogenic Ras activity in corneal CD31-enriched cells (presumably blood vessel endothelial cells) during SK. To our knowledge, this is one of the first reports of miRNA involvement in an infectious ocular disease. Manipulating miRNA expression holds promise as a therapeutic approach to control an ocular lesion that is an important cause of human blindness.",

"The cyclic AMP-responsive element binding- and NMDA-regulated microRNA miR-132 was significantly down-regulated in both the schizophrenic discovery cohort and a second, independent set of schizophrenic subjects. Analysis of miR-132 target gene expression in schizophrenia gene-expression microarrays identified 26 genes up-regulated in schizophrenia subjects.",
"Our data suggest miR-132 dysregulation and subsequent abnormal expression of miR-132 target genes contribute to the neurodevelopmental and neuromorphological pathologies present in schizophrenia.",
"Analysis of miRNA expression profiles from sporadic progressive supranuclear palsy (PSP) patients, a major 4R-tau tauopathy, showed that miR-132 is specifically down-regulated in disease. We demonstrate that miR-132 directly targets the neuronal splicing factor polypyrimidine tract-binding protein 2 (PTBP2), which protein levels were increased in PSP patients. miR-132 overexpression or PTBP2 knockdown similarly affected endogenous 4R:3R-tau ratios in neuronal cells. Finally, we provide evidence that miR-132 is inversely correlated with PTBP2 during post-natal brain development at the time when 4R-tau becomes expressed. Taken together, these results suggest that changes in the miR-132/PTBP2 pathway could contribute to the abnormal splicing of tau exon 10 in the brain, and sheds light into the potential role played by miRNAs in a subset of tauopathies.",
"Huntington's disease (HD) is a genetic neurodegenerative disease caused by abnormal CAG expansion. MicroRNAs (miRNAs) are short RNA molecules regulating gene expression, and are implicated in a variety of diseases including HD.",

"Levels of several microRNA (miR-10a, -10b, -212, -132, -495) were significantly altered. One of them (miR-132) has been reported to be highly inducible by growth factors and to be a key regulator of neurite outgrowth. Moreover, miR-132-recognition sequences were detected in the mRNA transcripts of two differentially expressed proteins. MicroRNA may thus represent novel biomarkers for neuronal malfunction and potential therapeutic targets for human neurodegenerative diseases.",
"The data indicate that micro-RNAs encoding miR-9, miR-124a, miR-125b, miR-128, miR-132 and miR-219 are abundantly represented in fetal hippocampus, are differentially regulated in aged brain, and an alteration in specific micro-RNA complexity occurs in Alzheimer hippocampus. These data are consistent with the idea that altered micro-RNA-mediated processing of messenger RNA populations may contribute to atypical mRNA abundance and neural dysfunction in Alzheimer's disease brain."

"Sorting nexin 27 (SNX27) regulates endocytic sorting/recycling and intracellular trafficking of ion channels and receptors."
] | [] | [
"Knockdown of SNX27 by siRNA in HEK293 cells raised MRP4 expression on the plasma membrane, increased the extrusion of 6-[(14)C]mercaptopurine, an MRP4 substrate, and conferred resistance against 6-[(14)C]mercaptopurine.",
"Sorting nexin 27 (SNX27) is a 62-kDa protein localized to early endosomes and known to regulate the intracellular trafficking of ion channels and receptors.",
"Finally, migration assays revealed that depletion of SNX27 from HeLa and mouse principal kidney cortical collecting duct cells significantly decreases cell motility. We propose a model by which SNX27 regulates trafficking of β-Pix to focal adhesions and thereby influences cell motility.",
"We found that SNX27a redirected part of 5-HT4(a)R to early endosomes.",
"sorting nexin 27 (SNX27), a recently described member of a protein family involved in intracellular trafficking,",
"SNX27 co-localized with transferrin receptor-positive vesicles, pointing to its participation in T cell endocytic recycling.",
"This protein is a unique member of the sorting nexin family of proteins, a group generally involved in the endocytic and intracellular sorting machinery",
"These previously unreported results indicate that SNX27 is a participant in NK cell polarization, as a mediator or target of the mechanism.",
"Like most sorting nexins, SNX27 possesses a functional PX domain that selectively binds the membrane phospholipid phosphatidylinositol-3-phosphate (PI3P) and is important for trafficking to the early endosome.",
"This is consistent with a role of SNX27 as a general regulator for sorting of membrane proteins containing a PDZ-binding motif, and its absence may alter the trafficking of these proteins, leading to growth and survival defects.",
"Sorting nexin 27 (SNX27) belongs to the sorting nexin family of proteins, which participate in vesicular and protein trafficking. Similarly to all sorting nexin proteins, SNX27 has a functional PX domain that is important for endosome binding, but it is the only sorting nexin with a PDZ domain.",
"These results identify SNX27 as a PDZ-containing component of the T cell immunological synapse, and demonstrate a role for this protein in the regulation of the Ras-ERK pathway, suggesting a functional relationship between SNX27 and DGKζ.",
"Sorting nexins have been implicated in trafficking of proteins through endosomal compartments."

"Nalmefene shows opioid receptor antagonism, binds the μ-opioid receptor (MOR1) and modulates opioidergic transmission in the CNS."
] | [] | [
"Opioids that stimulate the μ-opioid receptor (MOR1) are the most frequently prescribed and effective analgesics. Here we present a structural model of MOR1. Molecular dynamics simulations show a ligand-dependent increase in the conformational flexibility of the third intracellular loop that couples with the G protein complex. These simulations likewise identified residues that form frequent contacts with ligands. We validated the binding residues using site-directed mutagenesis coupled with radioligand binding and functional assays. The model was used to blindly screen a library of ∼1.2 million compounds. From the 34 compounds predicted to be strong binders, the top three candidates were examined using biochemical assays. One compound showed high efficacy and potency. Post hoc testing revealed this compound to be nalmefene, a potent clinically used antagonist, thus further validating the model. ",
"The neurobiological mechanism by which opioid modulators affect drinking behavior is based on the strong connection between the endogenous opioid system, the dopamine system and the influence of the CNS stress response.",
"Naltrexone- and to a lesser extent nalmefene- is an agent that modulates opioidergic transmission in the CNS and it shows a limited but well-studied efficacy in treating alcohol dependence. ",
"Several derivatives of Naltrexone, Nalmefene (Nal) and JKB-119, exert immunomodulatory activity; however, unlike Nal, JKB-119 does not show significant opioid receptor antagonism. "

"In a process of epithelial-mesenchymal transition (EMT), besides changing their adhesive repertoire, cancer cells employ developmental processes to gain migratory and invasive properties that involve a dramatic reorganization of the actin cytoskeleton and the concomitant formation of membrane protrusions required for invasive growth. An important type of such membrane protrusions are the invadopodia, which have been increasingly recognized as important drivers of local invasion in metastasis. They are basally-localized, actin-rich structures that concentrate protease activity to areas of the cell in contact with the extracellular matrix."
] | [] | [
"FHOD1, a poorly studied formin, appeared to be markedly upregulated upon EMT.",
"Furthermore, functional assays demonstrated that FHOD1 contributes to cell migration and invasion. Finally, FHOD1 depletion reduced the ability of EMT cancer cells to form invadopodia and to degrade extracellular matrix. Our results indicate that FHOD1 participates in cytoskeletal changes in EMT.",
"Invadopodia are considered to be crucial structures that allow cancer cells to penetrate across the extracellular matrix (ECM) by using matrix metalloproteinases (MMPs).",
"Previously, we isolated a highly invasive A431-III subline from parental A431 cells by Boyden chamber assay. The A431-III cells possess higher invasive and migratory abilities, elevated levels of MMP-9 and an enhanced epithelial-mesenchymal transition (EMT) phenotype. In this study, we discovered that A431-III cells had an increased potential to form invadopodia and an improved capacity to degrade ECM compared with the original A431 cells.",
"Activated Twist upregulates N-cadherin and downregulates E-cadherin, which are the hallmarks of EMT. Moreover, Twist plays an important role in some physiological processes involved in metastasis, like angiogenesis, invadopodia, extravasation, and chromosomal instability.",
"Transforming growth factor β (TGF-β)-stimulated epithelial-mesenchymal transition (EMT) is an important developmental process that has also been implicated in increased cell invasion and metastatic potential of cancer cells.",
"Herein, we demonstrate that TGF-β-induced Hic-5 up-regulation or ectopic expression of Hic-5 in normal MCF10A cells promoted increased extracellular matrix degradation and invasion through the formation of invadopodia.",
"These data identify Hic-5 as a critical mediator of TGF-β-stimulated invadopodia formation, cell migration, and invasion.",
"Recently, invadopodia have been increasingly recognized as important drivers of local invasion in metastasis. Invadopodia are basally-localized, actin-rich structures that concentrate protease activity to areas of the cell in contact with the extracellular matrix. We recently found that the transcription factor Twist1, a central regulator of the epithelial-mesenchymal transition (EMT), promotes invadopodia formation via upregulation of platelet-derived growth factor receptor (PDGFR) expression and activity.",
"Twist1-induced invadopodia formation promotes tumor metastasis",
"The Twist1 transcription factor is known to promote tumor metastasis and induce Epithelial-Mesenchymal Transition (EMT). Here, we report that Twist1 is capable of promoting the formation of invadopodia, specialized membrane protrusions for extracellular matrix degradation.",
"Twist1 induces PDGFRα expression, which in turn activates Src, to promote invadopodia formation. We show that Twist1 and PDGFRα are central mediators of invadopodia formation in response to various EMT-inducing signals.",
"Podosome-like structures of non-invasive carcinoma cells are replaced in epithelial-mesenchymal transition by actin comet-embedded invadopodia",
"Podosomes and invadopodia are actin-based structures at the ventral cell membrane, which have a role in cell adhesion, migration and invasion.",
"In conclusion, EMT affects the invasion machinery of oral squamous carcinoma cells. Non-invasive squamous carcinoma cells constitutively organize podosomes, whereas invasive cells form invadopodia. The club-ended cell extensions, or externalized invadopodia, are involved in ECM degradation and maintenance of contact to adhesion substrate and surrounding cells during invasion.",
"In a process of epithelial-mesenchymal transition (EMT), besides changing their adhesive repertoire, cancer cells employ developmental processes to gain migratory and invasive properties that involve a dramatic reorganization of the actin cytoskeleton and the concomitant formation of membrane protrusions required for invasive growth. The molecular processes underlying such cellular changes are still only poorly understood, and the various migratory organelles, including lamellipodia, filopodia, invadopodia and podosomes, still require a better functional and molecular characterization."

"The presence of TFT alterations seems to not be associated with clinical and prognostic implications in AKI patients.",

"Finally, low T3 but not low free triiodothyronine was associated with worse all-cause (Likelihood ratio = 45.4; P < 0.0001) and cardiovascular mortality (Likelihood ratio = 47.8; P < 0.0001) after adjustment for confounding factors.",
" In Cox analyses, fT3 was a significant predictor of mortality independent of the main traditional as well as non-traditional risk factors.",

The Kaplan-Meier analysis also showed significantly worse cumulative survival rates in the 'lower' T3 group (P<0.001). In the Cox regression analysis, low T3 was an independent predictor of all-cause mortality even after adjusting for traditional risk factors (hazard ratio=3.76, P=0.021). ",
"In CKD patients with proteinuria, low T3 concentration predicted all-cause mortality and cardiovascular event independently of the severity of proteinuria.",
"Low-T3 syndrome is a frequent finding among HD patients, but it does not predict outcome. However, serum fT3 level is a strong and inverse mortality predictor, in part explained by its underlying association with nutritional state and inflammation.",
"These data suggest that low FT3 levels are not predictive for mortality in a subgroup of stable HD patients who could survive more than 12 months.",
"Low fT3 is an independent predictor of death in hemodialysis patients. These data lend support to the hypothesis that thyroid dysfunction is implicated in the high risk of the ESRD population."

"Proteomic profiling of triple-negative breast carcinomas in combination with a three-tier orthogonal technology approach identifies Mage-A4 as potential therapeutic target in estrogen receptor negative breast cancer.",
"Further, we performed comparative quantitative proteomic and gene array analyses of these cells and identified potential novel markers of breast cancer cells with tumor-initiating features, such as lipolysis-stimulated lipoprotein receptor (LSR), RAB25, S100A14 and mucin 1 (MUC1), as well as a novel 31-gene signature capable of predicting distant metastasis in cohorts of estrogen receptor-negative human breast cancers.",

"Tuberous Sclerosis is a multisystem genetic disorder caused by mutation in TSC1 or TSC2 gene, that leads to hyperactivation of the mTOR signalling pathway, and subsequent dysregulation of cell growth control."
] | [
"Tuberous Sclerosis is caused by hyperactivation of the mTOR signalling pathway."
] | [
"Tuberous Sclerosis Complex (TSC) is a multisystem genetic disorder caused by mutation in either Tsc1 or Tsc2 genes that leads to the hyper activation of the mTOR pathway, a key signalling pathway for synaptic plasticity. ",
"Tuberous sclerosis, caused by germline mutations in the TSC1 or TSC2 genes, is associated with aberrant upregulation of the mammalian target of rapamycin (mTOR) signalling pathway, resulting in growth of tumours, including renal angiomyolipomas (AMLs).",
"Tuberous Sclerosis Complex is genetically determined with an autosomal dominant inheritance and is caused by inactivating mutations in either the TSC1 or TSC2 genes. TSC1/2 genes play a fundamental role in the regulation of phosphoinositide 3-kinase (PI3K) signalling pathway, inhibiting the mammalian target of rapamycin (mTOR) through activation of the GTPase activity of Rheb.",
"TSC is an autosomal dominant disorder caused by mutation in either of two genes: TSC1, encoding hamartin, and TSC2, encoding tuberin. Both proteins form a complex inhibiting mTOR signalling pathway and thus regulate cell size and proliferation.",
"Recent findings from this laboratory and others suggests that the tumour suppressor complex made of two proteins TSC1/hamartin and TSC2/tuberin, acts as a negative regulator of mTOR/S6K1 signalling. Mutations in either TSC1 or TSC2 are genetically linked to tuberous sclerosis complex (TSC) syndrome, which can lead to severe pathological consequences, including mental retardation, epilepsy and autism, as well as cardiac, pulmonary and renal failure.",
"Here we review recent findings demonstrating that the TSC1/TSC2 inhibitory complex normally acts on Rheb to mediate mTOR/S6K1-signalling.",
"Ras homologue enriched in brain (Rheb) represents a unique group of small GTPases and shares moderate sequence identity with the Ras/Rap subfamily. It acts downstream of nutrient signalling as the direct target of the tuberous sclerosis complex (TSC) and upstream of mTOR/S6K1/4EBP in the insulin-signalling pathway.",
"Recent studies suggest that the tuberous sclerosis complex Tsc1-Tsc2 may couple insulin signalling to Tor activity",
"Our genetic and biochemical analyses suggest that Rheb functions downstream of the tumour suppressors Tsc1 (tuberous sclerosis 1)-Tsc2 in the TOR (target of rapamycin) signalling pathway to control growth",
"Our results indicate activation of a mammalian target of rapamycin metabolic pathway in tuberous sclerosis lesions, which contributes to their growth.",
"Tuberous sclerosis (TSC) is an autosomal dominant hamartoma syndrome whose causative genes (TSC1 and TSC2) were identified 5 and 9 years ago respectively.",
"Recent studies in Drosophila have pinpointed a critical function for the DrosophilaTSC1/TSC2 homologues in the regulation of cell size. Epistasis experiments and a variety of biochemical studies that followed have indicated a critical function for these proteins in the highly conserved PI-3-kinase-Akt-mTOR signalling pathway.",
"Here, we show that tuberous sclerosis 1 (Tsc1) and Tsc2, tumour suppressors that are responsible for the tuberous sclerosis syndrome, antagonize this amino acid-TOR signalling pathway. We show that Tsc1 and Tsc2 can physically associate with TOR and function upstream of TOR genetically. In Drosophila melanogaster and mammalian cells, loss of Tsc1 and Tsc2 results in a TOR-dependent increase of S6K activity."

"The rapid accumulation of knowledge on biological signaling pathways and their regulatory mechanisms has highlighted the need for specific repositories that can store, organize and allow retrieval of pathway information in a way that will be useful for the research community. SPIKE (Signaling Pathways Integrated Knowledge Engine; http://www.cs.tau.ac.il/&~spike/) is a database for achieving this goal, containing highly curated interactions for particular human pathways, along with literature-referenced information on the nature of each interaction. To make database population and pathway comprehension straightforward, a simple yet informative data model is used, and pathways are laid out as maps that reflect the curator’s understanding and make the utilization of the pathways easy. The database currently focuses primarily on pathways describing DNA damage response, cell cycle, programmed cell death and hearing related pathways. Pathways are regularly updated, and additional pathways are gradually added. The complete database and the individual maps are freely exportable in several formats. The database is accompanied by a stand-alone software tool for analysis and dynamic visualization of pathways."

"The Barr body is the inactive X chromosome in a female somatic cell. It is readily identified as plano-convex structure of 2-3 micron in diameter on the periphery of the nuclear membrane. One of the X-chromosomes by a random inactivation process condenses to form X-chromatin (Barr body) in early embryonic life. Once this occurs, it is final and fixed for that cell and all its descendants (1,2). Barr body is an inactivated X chromosome in the normal female somatic cell. Inactivation of these chromosomes is known as Lyonization. Lyonization has both genetic and clinical significance. Barr body can be easily identified with ordinary stains. It also helps in identifying the sex of an individual when used judiciously. The Barr body has long been recognized as the cytological manifestation of the inactive X chromosome (Xi) in interphase nuclei. Despite being known for over 50 years, relatively few components of the Barr body have been identified. ",

"he advent of proteomics and genomics at a single-cell level has set the basis for an outstanding improvement in analytical technology and data acquisition.",
"The new-generation technology of single-cell analysis is able to better characterize a cell's population, identifying and differentiating outlier cells, in order to provide both a single-cell experiment and a corresponding bulk measurement, through the identification, quantification and characterization of all system biology aspects (genomics, transcriptomics, proteomics, metabolomics, degradomics and fluxomics). The movement of omics into single-cell analysis represents a significant and outstanding shift.",
"Laser ablation electrospray ionization (LAESI) is a novel method for the direct imaging of biological tissues by mass spectrometry. By performing ionization in the ambient environment, this technique enables in vivo studies with potential for single-cell analysis.",
"Other approaches for MS-based chemical imaging and profiling include those based on near-field laser ablation and inductively-coupled plasma MS analysis, which offer complementary capabilities for subcellular chemical imaging and profiling.",
"Mass spectrometry imaging and profiling of single cells.",
"his is rapidly changing with the recent examples of single cell genomics, transcriptomics, proteomics and metabolomics. The rate of change is expected to accelerate owing to emerging technologies that range from micro/nanofluidics to microfabricated interfaces for mass spectrometry to third- and fourth-generation automated DNA sequencers",
"Single-cell analysis (SCA) has been increasingly recognized as the key technology for the elucidation of cellular functions, which are not accessible from bulk measurements on the population level. Thus far, SCA has been achieved by miniaturization of established engineering concepts to match the dimensions of a single cell",
"Single-cell proteomic chip for profiling intracellular signaling pathways in single tumor cells.",
"The amount of single proteins in single cells can be as low as one copy per cell and is for most proteins in the attomole range or below; usually considered as insufficient for proteomic analysis.",
"n Arabidopsis thaliana, we have successfully identified nine unique proteins in a single-cell sample and 56 proteins from a pool of 15 single-cell samples from glucosinolate-rich S-cells by nanoLC-MS/MS proteomic analysis, thus establishing the proof-of-concept for true single-cell proteomic analysis",

"Succinate is an intermediate of the tricarboxylic acid (TCA) cycle, and plays a crucial role in adenosine triphosphate (ATP) generation in mitochondria.",
"In plasma, most metabolites in the central metabolic pathway (glycolysis and TCA cycle) were significantly downregulated after zymosan administration",
"Thus, IL-1beta+TNFalpha treated astrocytes show a marked decrease in glycogen levels, a slight but not significant decrease in lactate release as well as a massive increase in both the pentose phosphate pathway and TCA cycle activities.",
"A total of 77 and 92 metabolites were detected in serum and colon tissue, respectively, and among the metabolites the compositions of TCA cycle intermediates and amino acids changed depending on the degree of colitis",

"Several changes in substrate utilization for energy homeostasis were identified in severe AAH, including increased glucose consumption by the pentose phosphate pathway, altered tricarboxylic acid (TCA) cycle activity, and enhanced peptide catabolism. ",
"Enhanced mitochondrial glucose oxidation was achieved by increased recruitment of the NOTCH1 intracellular domain (NICD1) to nuclear and mitochondrial genes that encode respiratory chain components and by NOTCH-dependent induction of pyruvate dehydrogenase phosphatase 1 (Pdp1) expression, pyruvate dehydrogenase activity, and glucose flux to the TCA cycle.

"Nucleotide 1138 in transmembrane domain of FGFR3 gene is the hot point for mutation in ACH and hence its major pathologic cause. ",
"The nucleotide 1138 of FGFR3 gene is also the hotspot of mutation in Chinese patients with ACH. A simple and rapid molecular diagnostic method has been set up to differentiate ACH from other similar genetic dwarfism.",
"The diagnosis of achondroplasia was based on the presence of clinical and radiographic findings and confirmed by the presence of a common FGFR3 gene mutation (Gly380Arg) detected by restriction enzyme analysis and sequencing of the polymerase chain reaction products.",
"All patients carried the same glycine-to-arginine mutation at codon 380(G380R) of the transmembrane domain of FGFR3. ",
"The results suggest that the G380R mutation of FGFR3 is also a frequent mutation causing achondroplasia in Chinese. Detecting FGFR 3 gene mutation with PCR-SSCP and restriction enzymes analysis is a convenient, rapid and reliable molecular diagnostic assay for prenatal and early diagnosis of achondroplasia.",
"To evaluate whether mutation in the exon 10 of the fibroblast growth factor receptor 3(FGFR3) gene in common in Chinese patients with achondroplasia.",
"Achondroplasia (ACH) is the most frequent form of short-limb dwarfism. Recently, the gene mutation responsible for ACH has been identified in the transmembrane domain of the fibroblast growth factor receptor 3 gene. The cause of ACH is a point mutation at nucleotide 1138 of the cDNA, resulting in the substitution of an arginine residue for a glycine. ",
"Recent studies mapped the achondroplasia gene on chromosome region 4p16.3 and identified a common mutation in the gene encoding the fibroblast growth factor receptor 3 (FGFR3). "

5309fa5e970c65fa6b000003 | summary | What is the mode of action of Hsp90 inhibitors? | [
"Pharmacologic inhibition of Hsp90 involves interaction with the ATP-binding site of the chaperone. This exerts antiproliferative effects resulting in a marked suppression of tumor growth. Following treatment with a Hsp90 inhibitor, expression of a number of proteins is affected, and most notably the Hsp90 clients, leading to dysregulation of intracellular signal transduction, immune response, cell growth and maintenance, transport, and metabolism, finally resulting in cancer cell death through activation of both intrinsic and extrinsic apoptotic pathways."
] | [] | [
"In vitro, we show that pharmacologic inhibition of Hsp90 by IPI-504 exerts antiproliferative effects in a panel of pancreatic cancer cells in a dose- and time-dependent manner.",
"In pancreatic cancer xenografts obtained directly from patients with pancreas cancer, the agent resulted in a marked suppression of tumor growth.",
"Using a proteomic profiling analysis with isotope tags for relative and absolute quantitation labeling technique, we have identified 20 down-regulated proteins and 42 up-regulated proteins on IPI-504 treatment.tumor growth Identical changes were observed in the expression of the genes coding for these proteins in a subset of proteins including HSPA1B, LGALS3, CALM1, FAM84B, FDPS, GOLPH2, HBA1, HIST1H1C, HLA-B, and MARCKS. The majority of these proteins belong to the functional class of intracellular signal transduction, immune response, cell growth and maintenance, transport, and metabolism.",
"Dicoumarol, a long-established oral anticoagulant, is a new Hsp90 inhibitor that represses PTTG1/Securin gene expression and provokes apoptosis through a complex trait involving both intrinsic and extrinsic pathways.",
"Dicoumarol activity as an Hsp90 inhibitor is confirmed by smaller levels of Hsp90 clients in treated cells and inhibition of in vivo heat shock luciferase activity recovery assays.",
"Likewise, established Hsp90 inhibitors (17-allylamino-geldanamycin and novobiocin) repress PTTG1/Securin gene expression. ",
"However, effects on PTTG1/Securin could be partially ascribed to inhibition of the Ras/Raf/extracellular signal-regulated kinase pathway.",
"To document this field, we have studied two Hsp90 inhibitors (radicicol and geldanamycin), known to interact with the ATP-binding site of Hsp90 (the Bergerat fold),",
"One of these is the novel agent 17-allylamino-17-demethoxygeldanamycin that acts to inhibit the hsp90 molecular chaperone. Treatment of four human colon cancer cell lines with iso-effective concentrations of this agent resulted in depletion of c-raf-1 and akt and inhibition of signal transduction.",
"The expression of hsp90 client protein genes was not affected, but hsc hsp70, hsp90beta, keratin 8, keratin 18 and caveolin-1 were deregulated following treatment."

"The autoantibodies implicated in the Lambert-Eaton myasthenic syndrome (LES), which are known to inhibit ICa and INa in bovine adrenal chromaffin cells, also significantly inhibited INa in SCLC cells.",
"These results indicate that (i) action potentials in human SCLC cells result from the regenerative increase in voltage-gated Na+ channel conductance; (ii) fundamental characteristics of SCLC Na+ channels are the same as the classical sodium channels found in a variety of excitable cells; and (iii) in some LES patients, SCLC Na+ channels are an additional target of the pathological IgG present in the patients' sera.",
"Clinical features were those of LES and occurred insidiously in this 68-year old man: proximal weakness predominant in the lower limbs, generalized areflexia, dryness of the mouth and partial right eye palsy. Investigations disclosed a small cell lung cancer.",
"Voltage-gated Ca2+ channels may be important to the secretion of ectopic hormones and the etiology and pathogenesis of Lambert-Eaton syndrome, an autoimmune disorder of the motor nerve terminal in which autoantibodies directed against voltage-gated Ca2+ channels are produced.",

The pathological diagnosis after mediastinoscopy was negative. Twenty-five months later, an opacity on chest X-ray led to a biopsy which revealed a squamous cell carcinoma.",
"LEMS is generally associated with small cell lung cancer occurring in three percent of cases.",
"However, the case that we report shows the unusual association of LEMS with non small-cell lung cancer and highlights the difficulties associated in the management of this condition.",

"Congenital cataracts, facial dysmorphism and peripheral neuropathy are three major features of the CCFDN syndrome. Other described signs and symptoms of the CCFDN syndrome include microcornea, microphthalmos, micropupil, floppy eyelid syndrome, pseudoptosis, nystagmus, congenital esotropia, impairment of distant visual acuity, ataxia, pyramidal signs, mild chorea, short stature, muscular atrophy, delayed early motor and intellectual development, hypogonadotrop hypogonadism, hypomyelination of the peripheral nervous system, serious complications related to general anaesthesia and parainfectious rhabdomyolysis."

"Because of our experience in neuromuscular disorders, we choose six, frequent, autosomal recessive disorders for these clinical and genetic studies: hereditary motor and sensory neuropathy type Lom (HMSNL), hereditary motor and sensory neuropathy type Russe (HMSNR), congenital cataracts facial dysmorphism syndrome (CCFDN), limb-girdle muscular dystrophy 2C (LGMD2C), congenital myasthenic syndrome (CMS) and spinal muscular atrophy (SMA).",

"Congenital cataracts-facial dysmorphism-neuropathy syndrome (CCFDN, MIM: 604168), is a recently delineated neurogenetic disease causing recurrent episodes of rhabdomyolysis; prevention and early diagnosis of rhabdomyolysis should be part of the clinical management of the disease.",
"Congenital Cataracts Facial Dysmorphism Neuropathy (CCFDN) syndrome is a complex developmental disorder of autosomal recessive inheritance. ",

"The major differential diagnosis of MSS is the syndrome defined by congenital cataracts, facial dysmorphism and peripheral neuropathy (CCFDN), which is localised to 18qter.",
"The CCFDN syndrome is a complex phenotype involving multiple systems, characterized by facial dysmorphism, congenital cataracts, microcorneae, delayed early motor and intellectual development, hypogonadotrop hypogonadism, hypomyelination of the peripheral nervous system, and serious complications related to general anaesthesia. ",
"Developmental abnormalities include congenital cataracts and microcorneae, primary hypomyelination of the peripheral nervous system, impaired physical growth, delayed early motor and intellectual development, mild facial dysmorphism and hypogonadism. Para-infectious rhabdomyolysis is a serious complication reported in an increasing number of patients. ",
"CONCLUSIONS: Early-onset congenital cataracts associated with microcornea, microphthalmos, and micropupil are essential ocular features of the CCFDN syndrome and are the first recognizable signs during early infancy. ",
"All patients showed a peripheral, demyelinating neuropathy and varying degrees of ataxia. In the older patients, muscular atrophy in distal muscles and facial dysmorphism was evident. Early-onset bilateral congenital cataracts associated with microcornea, microphthalmos, and micropupil could be found in all patients. All children had floppy eyelid syndrome and pseudoptosis.",
"All patients had syndrome-associated nystagmus and congenital esotropia. Distant visual acuity could be classified as severe to moderate impairment, whereas near visual acuity was much better (mild to moderate impairment).",
"Because these families originated from the same genetically isolated founder population as did patients with congenital cataracts facial dysmorphism neuropathy (CCFDN) syndrome, and because the two syndromes have clinical manifestations in common, we hypothesized that the two related, albeit distinct, syndromes may represent clinical variants of a single genetic disorder.

5167be1a298dcd4e5100005c | yesno | is intense physical activity associated with longevity ? | [
"Several survival studies showed that professional athletes has higher longevity than general population. These epidemiological data matches the evidences that long-term endurance training induces in elderly subjects an increased HRV and a higher exercise working capacity, which are well-established predictors of cardiovascular and overall mortality, and also telomere length."
] | [
"yes"
] | [
"We found a very significant increase in average longevity (17%) of the cyclists when compared with the general population. The age at which 50% of the general population died was 73.5 vs. 81.5 years in Tour de France participants. Our major finding is that repeated very intense exercise prolongs life span in well trained practitioners.",
"Competitive exercise does not induce cardiac damage in individuals with healthy hearts, but does induce physiological functional and structural cardiac adaptations which have positive effects on life expectancy.",
"Medallists lived an average of 2.8 years longer than controls. Medallists in eight of the nine country groups had a significant survival advantage compared with controls. Gold, silver, and bronze medallists each enjoyed similar sized survival advantages. Medallists in endurance sports and mixed sports had a larger survival advantage over controls at 30 years (1.13, 1.09 to 1.17; 1.11, 1.09 to 1.13) than that of medallists in power sports (1.05, 1.01 to 1.08). CONCLUSIONS: Olympic medallists live longer than the general population, irrespective of country, medal, or sport. This study was not designed to explain this effect, but possible explanations include genetic factors, physical activity, healthy lifestyle, and the wealth and status that come with international sporting glory.",
"Long-term endurance training induces in elderly subjects an increased HRV and a higher exercise working capacity, which are well-established predictors of cardiovascular and overall mortality.",
"Sports activity in adolescents and young adults was associated with an increased risk of SD, both in males and females. Sports, per se, was not a cause of the enhanced mortality, but it triggered SD in those athletes who were affected by cardiovascular conditions predisposing to life-threatening ventricular arrhythmias during physical exercise."
