اثر یک جلسه تمرین مقاومتی بر بیان mir-1 و ژن های myod،mef2 و hdac4 در عضلات تند و کند موش های ویستار
هدف این تحقیق بررسی اثر یک جلسه تمرین مقاومتی بر بیان mir-1 و بیان ژن های myod،mef2 و hdac4در عضلات تند و کند رت های ویستار بود. 15 رت نر ویستار از انستیتو پاستور خریداری و تمام شرایط طبیعی (دما، چرخه خواب و بیداری، غذا و...) برای آنها فراهم شد. رت ها به صورت تصادفی به دو گروه تمرینی(n=10) و کنترل(n=5) تقسیم شدند. گروه تمرینی یک جلسه تمرین مقاومتی را اجرا کردند [صعود از نردبان 26 پله 1 متری با ...
BACKGROUND Mechanical ventilation (MV) used in patients with acute respiratory distress syndrome (ARDS) can cause diffuse lung inflammation, an effect termed ventilator-induced lung injury, which may produce profound pulmonary fibrogenesis. Histone deacetylases (HDACs) and serine/threonine kinase/protein kinase B (Akt) are crucial in modulating the epithelial-mesenchymal transition (EMT) during...
Interleukin-1β (IL-1β)-induced inflammatory response is associated with osteoarthritis (OA) and its development. Histone deacetylase (HDAC) may be involved in regulating this pathogenesis, but the mechanism has yet to be elucidated. The aim of the present study was to investigate the mechanism underlying the regulation of IL‑1β‑stimulated catabolic degradation of cartilage by HDAC. An in vitro ...
BACKGROUND While eating disorders (EDs) are thought to result from a combination of environmental and psychological stressors superimposed on genetic vulnerability, the neurobiological basis of EDs remains incompletely understood. We recently reported that a rare missense mutation in the gene for the transcriptional repressor histone deacetylase 4 (HDAC4) is associated with the risk of developi...
The mechanisms by which deregulated nuclear factor erythroid-2-related factor 2 (NRF2) and kelch-like ECH-associated protein 1 (KEAP1) signaling promote cellular proliferation and tumorigenesis are poorly understood. Using an integrated genomics and ¹³C-based targeted tracer fate association (TTFA) study, we found that NRF2 regulates miR-1 and miR-206 to direct carbon flux toward the pentose ph...
Piceatannol, a resveratrol metabolite, is a phenolic compound found in red wine and grapes. We investigated the effect of piceatannol on renal fibrosis and histone deacetylase (HDAC) expression in a mouse model of unilateral ureteral obstruction (UUO). Fibrosis was established by UUO and piceatannol was intraperitoneally injected for 2 weeks. Piceatannol suppressed extracellular matrix (ECM) pr...
MiR-9, a neuron-specific miRNA, is an important regulator of neurogenesis. In this study we identify how miR-9 is regulated during early differentiation from a neural stem-like cell. We utilized two immortalized rat precursor clones, one committed to neurogenesis (L2.2) and another capable of producing both neurons and non-neuronal cells (L2.3), to reproducibly study early neurogenesis. Exogeno...
Histone deacetylases (HDACs) play a pivotal role in eukaryotic gene expression by modulating the levels of acetylation of chromatin and related transcription factors. In contrast to class I HDACs (HDAC1, -2, -3 and -8), the class IIa HDACs (HDAC4, -5, -7 and -9) harbor cryptic deacetylases activity and recruit the SMRT-HDAC3 complex to repress target genes in vivo. In this regard, the specific ...
Epstein-Barr virus (EBV) EBNA-LP is a transcriptional coactivator of EBNA2 that works though interaction with the promyelocytic leukemia nuclear-body-associated protein Sp100A. EBNA-LP localizes predominantly in the nucleus through the action of nuclear localization signals in the repeated regions of the protein. EBNA-LP has also been detected in the cytoplasm, and a previous study suggested th...
