چکیده زمینه و هدف: دیابت قندی یک اختلال مزمن متابولیک همراه با افزایش قند خون می باشد که به طور نامطلوبی هر دو سیستم عصبی مرکزی و محیطی را درگیر می کند. از آن جا که ژن های خانواده ی bcl-2 نقش مهمی در تنظیم آپوپتوز دارند، هدف از مطالعه ی حاضر بررسی اثرات انسولین و اسیداسکوربیک بر بیان ژن های خانواده ی bcl-2 نظیر bax (القا کننده ی آپوپتوز)، bcl-2 و bcl-xl (مهارکننده ی آپوپتوز) در هیپوکامپ موش های...
Hepatocyte growth factor (HGF) is known to promote renal epithelial cell survival by dual mechanisms involving Bad phosphorylation and Bcl-xL induction. However, it remains elusive as to the relative contributions of these two events to HGF-mediated cytoprotection. Here we investigated the role and mechanism of HGF in protecting renal epithelial cells from death induced by oxidant stress both i...
Seven forms of X-linked (XL) immunodeficiency have been described (XL agammaglobulinemia, XL severe combined immunodeficiency [SCID], Wiskott-Aldrich syndrome, XL chronic granulomatous disease, XL hyper-IgM syndrome with low IgG and IgA, and XL lymphoproliferative syndrome), and properdine deficiency. Although there are (some) phenotypic variants, diagnosis is relatively simple on the basis of ...
Ara-C has been shown to induce apoptosis of human acute myelogenous leukemia HL-60 cells. The DNA repair enzyme poly(ADP-ribose) polymerase (PARP) is known to be degraded during apoptosis. PARP as a substrate is cleaved by the Yama protease, encoded by the CPP32beta/Yama gene. Yama belongs to the interleukin 1beta converting enzyme/ced-3 family of cysteine proteases that are activated as a casc...
The caspases are cysteine proteases that have been implicated in the execution of programmed cell death in organisms ranging from nematodes to humans. Many members of the Bcl-2 family, including Bcl-XL, are potent inhibitors of programmed cell death and inhibit activation of caspases in cells. Here, we report a direct interaction between caspases and Bcl-XL. The loop domain of Bcl-XL is cleaved...
Anti-apoptotic B-cell lymphoma 2 (Bcl-2) family members target several intracellular Ca(2+)-transport systems. Bcl-2, via its N-terminal Bcl-2 homology (BH) 4 domain, inhibits both inositol 1,4,5-trisphosphate receptors (IP3Rs) and ryanodine receptors (RyRs), while Bcl-XL, likely independently of its BH4 domain, sensitizes IP3Rs. It remains elusive whether Bcl-XL can also target and modulate Ry...
Evidence exists that deregulation of apoptosis is involved in the mechanisms of cancer development, and the somatic mutations of apoptosis-related genes have been reported in human cancers. Bcl-XL/Bcl-2-associated death promoter (Bad), a proapoptotic member of Bcl-2 family, plays an important role in the intrinsic apoptosis pathway. To explore the possibility that the genetic alterations of Bad...
In our previous research, the Tamarix androssowii LEA gene (Tamarix androssowii late embryogenesis abundant protein Mrna, GenBank ID: DQ663481) was transferred into Populus simonii × Populus nigra. Among the eleven transgenic lines, one exhibited a dwarf phenotype compared to the wild type and other transgenic lines, named dwf1. To uncover the mechanisms underlying this phenotype, digital gene ...
