Human sirtuin 1 (SIRT1) is a NAD(+)-dependent deacetylase that participates in cell death/survival, senescence and metabolism. Although its substrates are well characterized, no direct regulators have been defined. Here, we show that SIRT1 associates with SKI-interacting protein (SKIP) and modulates its activity as a coactivator of retinoic acid receptor (RAR). Binding assays indicated that SKI...
Hepatocellular carcinoma (HCC) is a highly malignant tumor with a poor prognosis. Treatment of HCC is complicated by the fact that the disease is often diagnosed at an advanced stage when it is no longer amenable to curative surgery, and current systemic chemotherapeutics are mostly inefficacious. Sirtuin 1 (SIRT1) is a class III histone deacetylase that is implicated in gene regulations and st...

ABSTRACT Background and Objectives: Cardiac rehabilitation improves functional capacity of post-coronary artery bypass grafting (CABG) patients. Therefore, the aim of this study was to evaluate effects of eight weeks of cardiac rehabilitation on serum levels of sirutin1 (SIRT1) and functional capacity of post-CABG patients. Methods: Forty-five non-active men (mean ag...
Chronic ethanol feeding causes liver steatosis in animal models by upregulating the sterol regulatory element-binding protein 1 (SREBP-1), which subsequently increases the synthesis of hepatic lipid. SREBP-1 activity is regulated by reversible acetylation at specific lysine residues. The present study tests the hypothesis that activation of SREBP-1 by ethanol may be mediated by mammalian sirtui...
Increased osteoclast-mediated bone resorption is characteristic of osteoporosis, malignant bone disease and inflammatory arthritis. Targeted deletion of Sirtuin1 (Sirt1), a key player in aging and metabolism, in osteoclasts results in increased osteoclast-mediated bone resorption in vivo, making it a potential novel therapeutic target to block bone resorption. Sirt1 activating compounds (STACs)...
سابقه وهدف: لوسمی میلوئید مزمن یک بیماری میلوپرلیفراتیو کلونال میباشد که با فیوژن bcr-abl تشخیص داده میشود. با ظهور مهارکنندهای تیروزین کیناز مثل ایماتینیب پیشرفتهای مهمی در درمان این بیماری صورت گرفته است. اما وجود مقاومت دارویی بر علیه این دارو ، یک مانع در درمان لوسمی میلوئید مزمن محسوب میشود.) sirt1سیرتونین یک ( عملکرد داستیلاز دارد و در بسیاری از سرطانها دارای افزایش بیان می باشد.این تحقیق...
BACKGROUND Mammalian sirtuins are homologs to the yeast silent information regulator 2 (Sir2), which is an NAD-dependent deacetylase. Sirtuins are comprised of 7 proteins, and each has different target proteins. Sirtuin 1 (SIRT1) plays important roles in maintaining metabolic functions and immune responses, and SIRT3 protects cells from oxidative stress-induced cell death. Both SIRT1 and SIRT3 ...
SIRT1 is a NAD+ (nicotinamide adenine dinucleotide) dependent histone deacetylase. Growing evidences suggestes that SIRT1 plays the part of metabolic sensor in regulating the level of acetylation in cell proliferation and other aspects of tumor development. The expression of SIRT1 is related to multiple pathways of resistance. In this review, we have summarizes the recent progress of SIRT1, and...
OBJECTIVE The AML1-ETO fusion protein (AE) resulting from the t(8;21) translocation is highly related to the pathogenesis and development of leukemia. microRNA-9 (miR-9) acts as a tumor suppressor gene in AE-positive acute myeloid leukemia (AML). Silent mating type information regulation 2 homolog-1 (SIRT1) is overexpressed in most cancer cells by increasing proliferation as a tumorigenic gene....
