3,4- Methylenedioxymethamphetamine (MDMA or "Ecstasy") is a psychoactive and hallucinogenic drug of abuse. MDMA has been shown to produce neurotoxicity both in animals and humans. Recently, the vasodilator drugs such as pentoxifylline is one of the new strategies which have been considered as neuroprotector. In this study effect of pentoxifylline on bcl-2 gene expression changes in hippocampus ...
Background: BCL-2 is the most important anti-apoptotic regulator and Bax is a pro-apoptotic protein. The status of these parameters or the ration of BCL-2 to BAX is important in malignant cell fate as well as normal cells. Methods: Sixty-two ALL patients and 62 healthy sex-and age-matched controls were studied. After genotyping, the promoter region of the BAX and BCL-2 genes by RFLP-PCR meth...
To extend the mammalian cell death pathway, we screened for further Bcl-2 interacting proteins. Both yeast two-hybrid screening and lambda expression cloning identified a novel interacting protein, Bad, whose homology to Bcl-2 is limited to the BH1 and BH2 domains. Bad selectively dimerized with Bcl-xL as well as Bcl-2, but not with Bax, Bcl-xs, Mcl-1, A1, or itself. Bad binds more strongly to ...
Ischemia-reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. Ischemia-reperfusion brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. Twenty–four male Wistar rats (250-300 g body wt) were used in this study. The animals were divided into four groups of 6 rat...

زمینه و هدف: گیاه حرا (avicennia marina) یکی از گیاهان دارویی ایران و از اعضای خانواده آکانتاسه است که در مناطق حاره ای و نیمه حاره ای می روید. هدف از این مطالعه بررسی اثرات ضد سرطانی و ضد باکتریایی عصاره های مختلف برگ گیاه حرا است. در این پژوهش مکانیسم اثر ضد سرطانی یک فراکسیون جداسازی شده از عصاره متانولی بر روی سلول های سرطان سینه انسانی بررسی گردید. روش ها: برگ گیاه حرا در فروردین ماه سال 1...
background and aims: epigallocatechin-3-gallate (egcg) is a polyphenolic compound from green tea, which its anticancer effects on many types of cancers have been confirmed, but the molecular mechanism by which egcg induces apoptosis remains unknown. the aim of the present study was to investigate anti-proliferative properties and apoptotic signaling pathway of egcg on pc3 human prostate cancer ...
Bcl-2 and Bcl-xL are inhibitors of apoptosis frequently overexpressed in solid tumors. The bcl-2 and bcl-xL mRNAs share a region of homology comprising nucleotides 605-624 and 687-706, respectively, which differs by only three nucleotides. This sequence does not occur in the proapoptotic splice variant bcl-xS. To test the possibility that oligonucleotides targeting this region have the potentia...
Introduction: Follicular lymphoma (FL) is a lymphoid neoplasia arising from germinal center B cells, characterized by the t(14;18) translocation and subsequent upregulation of anti-apoptotic B-cell 2 (BCL2) proteins. While an indolent nature favorable prognosis, FL remains generally incurable. Furthermore, histological transformation (HT) to high-grade histology, associated with markedly aggres...
سیاه دانه (nigella sativa l.) متعلق به خانواده آلاله، جزء گیاهان دارویی مهم می باشدکه انواع متعددی از متابولیت های ثانویه ی گیاهی از جمله ترپن ها را تولید می کند. مونوترپن ها و تری ترپن ها از مهم ترین گروه های تشکیل دهنده ی ترپن ها می باشند. در مسیر بیوسنتزی مونوترپن ها تحت عنوان مسیرmep واقع در پلاستید، ژن های مختلفی دخیل می باشند که مونوترپن سنتازها تحت عنوان ژن های محدودکننده سرعت واکنش در ا...
