Ischemia-Reperfusion (I/R) injury causes ROS overproduction, creating oxidative stress, and can trigger myocyte death, resulting in heart failure. Tyrosol is an antioxidant abounded in diets and medicine. Our objective was to investigate the protective effect of tyrosol on I/R-caused mortality in H9c2 cardiomyocytes through its influence on ROS, Hsp70, ERK, JNK, Bcl-2, Bax and caspase-8. A simu...
زمینه و هدف: دوران بارداری بعنوان بخش مهمی از زندگی زنان، از جوانب مختلف از جمله فعالیت بدنی میتواند بر شاخص های مختلف سلامت نوزاد موثر باشد. یکی از بیماری های رایج و رو به گسترش بیماری گرفتگی عروق است که eNOS،BCL-2 و BAX از شاخص های مرتبط با آن است. لذا پژوهش حاضر با هدف بررسی تاثیر تمرین هوازی در قبل و هنگام بارداری در موشهای صحرایی نژاد اسپراگداولی بر بیان ژن eNOS،BCL-2 و BAX در بافت شریا...
background: in this study, the protective effect of thymoquinone (tq) and nigella sativa seeds oil (nso) was evaluated against oxidative damages induced by ethanol in rats. methods: animals were treated with ethanol 40% daily by gavages once a day for 4 weeks. nso and tq were injected intraperitoneal once a day for 4 weeks. the histopathological examination of liver, kidney, brain and heart was...
BACKGROUND It has been suggested that progression of superficial bladder cancer may be regulated at the molecular level by a typical pattern of expression of genes involved in apoptosis. Recently LIVIN, belonging to the inhibitors of apoptosis (IAP) family, has been found to be expressed in most solid tumors, where its expression is suggested to have prognostic significance. No data are availab...
BACKGROUND Our previous study has demonstrated that knockdown of activated ERK1/2(pERK1/2) sensitizes pancreatic cancer cells to chemotherapeutic drug gemcitabine (Gem) treatment. However, the details of this survival mechanism remain undefined. It has also shown that Bcl-2 confers resistance and Bax sensitizes to gemcitabine-induced apoptosis in pancreatic cancer cells. Furthermore, the extrac...
This work investigates the effects of oxidative stress due to exhaustive training on uncoupling protein 2 (UCP2) and Bcl-2/Bax in rat skeletal muscles. A total of 18 Sprague-Dawley female rats were randomly divided into three groups: the control group (CON), the trained control group (TC), and the exhaustive trained group (ET). Malondialdehyde (MDA), superoxide dismutase (SOD), xanthine oxidase...
هدف از آپوپتوز دارویی شناسایی خاصیت القا آپوپتوز توسط مواد شیمیایی ، دارویی ویا ترکیبات طبیعی وکشف مکانیسم آنها جهت امکان تقویت و اختصاصی ساختن اثرات آنهاست. از این خاصیت تحت عنوان آپوپتوز القا شده توسط داروها نام برده شده و روز به روز به تعداد چنین ترکیباتی افزوده می شود. از داروهایی که چنین خاصیتی را نشان داده است میتوان از آرتمیزینین نام برد. این ترکیب یک سزکویی ترپن لاکتون استخراج شده از گی...
Although microRNA (miR)-145 has been identified to be a tumor suppressor in various types of tumor, it promotes the progression of non-small cell lung cancer (NSCLC). However, the precise underlying molecular mechanism of its action remains unclear. The present study investigated the effects of miR-145 on the proliferation, invasion, metastasis and apoptosis of the NSCLC A549 cell line and the ...
Abnormal regulation of apoptosis is observed in ischemic injury and may contribute to the pathogenesis of atherosclerosis. However, its role in cardiac allograft vasculopathy (CAV), the fundamental lesion of chronic rejection (CR) in heart transplantation, remains uncertain. To clarify this issue, apoptosis was quantitated in myocardium and coronary arteries from 5 cardiac allograft donors (NL)...
