در سالهای اخیر، فلاونوئیدها به عنوان گروهی از ترکیبات پلیفنولی، به دلیل اثرات سودمند بر سلامتی مورد توجه پژوهشگران قرار گرفتهاند. مطالعات متعددی نشان میدهند که اثرات ضدسرطانی فلاونوئیدها از طریق مهار مسیر انتفال پیام PI3K/Akt میباشد. تنظیم نبودن این مسیر به شروع پاسخ های متعددی مانند: رشد، تکثیر، بقا و تحرک سلولی و در نهایت پیشرفت تومور منجر میشود. در این مطالعهی مروری، اثرات ضدسرطانی فل...
objective(s):multidrug resistance (mdr) of cancer cells is a major obstacle to successful chemotherapy. overexpression of breast cancer resistance protein (bcrp) is one of the major causes of mdr. in addition, it has been shown that pi3k/akt signaling pathway involves in drug resistance. therefore, we evaluated the effects of novel approaches including sirna directed against bcrp and targeted t...
سابقه و هدف: مقاومت به داروهای شیمیدرمانی یکی از مهمترین معضلات درمانی بیماران مبتلاء به لوسمی لنفوبلاستیک حاد (ALL) میباشد. اختلال در مسیر فسفاتیدیلاینوزیتول-3 کیناز (PI3K) و همچنین ارتباط آن با بروز پدیده مقاومت باعث شده که مهارکنندههای این مسیر، خصوصا Buaprlisib به عنوان یکی از امیدبخشترین داروهای درمان سرطان معرفی شوند. هدف از این مطالعه، بررسی تاثیر مهار مسیر PI3K/Akt توسط داروی Bupa...
Objective(s): Previous study has indicated that triiodothyronine (T3) facilitated cartilage degeneration in osteoarthritis (OA). This study aimed to investigate the effects of T3 on angiogenesis-related factor expression in human osteoblasts of OA subchondral bone.Materials and Methods: The subchondral bone specimens were obtained from O...
Intracerebroventricular stereptozotocin (STZ) treatment has been described as a suitable model for sporadic Alzheimer’s disease (sAD). Centrally administered STZ decreases insulin and insulin receptors in the brain and interrupts PI3/Akt signaling pathway and GSK-3β. Additionally it raises Bax/Bcl-2 ratio and prompts hippocampal apoptosis. Agmatine, a polyamine derived from L-arginin...
background: osteosarcoma is a malignant tumor with high mortality but effective therapy has not yet been developed. berberine, an isoquinoline alkaloid component in several chinese herbs including huanglian, has been shown to induce growth inhibition and the apoptosis of certain cancer cells. the aim of this study was to determine the role of berberine on human osteosarcoma cell lines u2os and ...
background: the phosphatidylinositol 3-kinase/akt signaling pathway is recognized as a key driver of cancer cell survival and proliferation, and is often contingent upon an impairment of expression/function of the pten tumor suppressor, a negative regulator of this pathway. in addition, the cytoskeletal signaling protein tensin 2 has also been implicated as a negative regulator of this pathway....
The purpose of this study was to explore the mechanism Solanine disrupting energy metabolism in human renal cancer ACHN cells and clarify its target. specific method culture cell lines, intervene with high, medium low concentrations. content ATP measured by ELISA method. expression HIF-1α protein PI3K, AKT, p-PI3K, p-AKT PI3K/AKT pathway were detected Western blotting. results showed that compa...
Introduction: The mechanism of putative cytotoxicity of 4-[3-(cyclopentyloxy)-4-methoxyphenyl]-2-pyrrolidone (rolipram), a specific phosphodiesterase-4 (PDE4) inhibitor, on glioblastoma multiforme (GBM) is almost unknown. This study aimed to investigate the role of protein kinase B (Akt) pathway in the cytotoxic effect of rolipram on human GBM U87 MG cell line and tumor-initiating cells (TICs) ...
objective(s): we previously reported a series of quinazoline derivatives as vascular-targeting anticancer agents. in this study, we investigated the mechanism underlying the anti-angiogenic activity of the quinazoline derivative compound 11d. materials and methods: we examined the effects of quinazoline derivative 11d on vascular endothelial growth factor receptor-2 (vegfr2) activation via vegf...
