Tumor Necrosis Factor- is greatly implicated in heart pathophysiology, while it is upregulated in the failing myocardium. A major target in TNF--induced heart failure is the muscle specific intermediate filament cytoskeleton, comprised by desmin. We analysed the effect of cardiac-specific overexpression of TNF- in the Des-/- myocardium, which is a known model of dilated cardiomyopathy.

View SamplesThe aim of this study was to investigate the molecular mechanisms implicated in this mouse model of nemaline myopathy, and to further compare the molecular disease response in different skeletal muscles. For this purpose, snap frozen skeletla muscle specimens from wild type and transgenic for alpha tropomyosin slow mice were studied. Five different muscle types were used (diaphragm, plantaris, extensor digitorum longus, tibialis anterior, gastrocnemus). Mice were sacrificed between 7 and 10 months. RNA pools from 3-5 animals were created and each pool was hybridized to a U74Av2 Affymetrix GeneChip. Datasets from 36 GeneChips were included in this study.

View SamplescJun is a transcription factor activated by phosphorylation by SAPK/JNK MAP kinase pathway that has been linked to atherosclerosis. Adenovirus mediated gene transfer of a dominant negative form of cJun in C57BL/6 mice increased greatly the apolipoprotein E (ApoE) mRNA and plasma apoE levels and induced dyslipidmia, characterized by increased plasma cholesterol, triglyceride and VLDL levels and accumulation of discoidal HDL particles. Unexpectedly, infection of ApoE-/- mice with adenovirus expressing dn-cJun reduced by 50% plasma cholesterol, suggesting that the dn-cJun affected other genes that control plamsa cholesterol. To determine the molecular pathways implicated in this process we performed whole genome expression profiling using total RNA from the liver of infected ApoE-/- mice.

View SamplesWe show that Retinal pigment epithelium (RPE) secreted-factor, pigment epithelium derived factor (PEDF) secreted/derived from primary or iPSC-derived retinal pigment epithelium (RPE)RPE, dramatically inhibitsed the cell growth of iPSCs. PEDF was detected abundantly in culture supernatant media of primary and iPSC-derived RPE. We examined the gene expression in primary RPE and iPS-derived RPE.

View SamplesThe Mesio-Temporal Lobe Epilepsy (MTLE) syndrome is the most common form of intractable epilepsies. It is characterized by the recurrence of focal seizures occurring in mesio-temporal limbic structures and is often associated with hippocampal sclerosis and drug resistance.

View SamplesPrimary Sjgrens syndrome (SS or autoimmune epithelitis) is a relatively common autoimmune disorder that is primarily characterized by chronic lymphoepithelial inflammatory reactions in the exocrine glands, mainly the salivary and lachrymal glands. It may extend from disease confined to the exocrine glands (organ-specific exocrinopathy) to various extraglandular manifestations (systemic disease) and the development of B-cell lymphoma. Several studies from our laboratory had provided evidence for the strong implication of ductal salivary gland epithelial cells (SGEC) in the pathogenesis of Sjgrens syndrome (SS), including the development of salivary gland infiltrating lesions and of adverse systemic clinical complications, such as the development of B-cell lymphoma. In fact, the comparative assessment of non-neoplastic SGEC lines derived from SS patients and disease controls had indicated that the ductal epithelia of SS patients manifest an intrinsically activated status that is associated with distinct aberrant phenotypic and functional features encountered in inflamed cells.
