The antiapoptotic protein Bcl-2 is overexpressed in a majority of breast cancers, and is associated with a diminished apoptotic response and resistance to various antitumor agents. Bcl-2 inhibition is currently being explored as a possible strategy for sensitizing breast cancer cells to standard chemotherapeutic agents. Antisense Bcl-2 oligonucleotides represent one method for blocking the anti...
ژن های bax و bcl-2 از جمله ژن های مهم دخیل در مسیر میتوکندریایی آپاپتوز به شمار می روند. از آن جا که در سلول های سرطانی تعادل بین تکثیر و آپاپتوز به هم خورده و سلول ها برای رشد و تکثیر بی رویه خود نیاز به مهار آپاپتوز دارند، ارتباط مستقیمی میان بیان این ژن ها و فرایند سرطانی شدن وجود دارد. بنابراین بررسی تغییرات بیانی این ژن ها می تواند از جمله هدف های درمانی و یا تشخیصی در مطالعات سرطان به شما...
We stably transfected early passage chondrocytes with an anti-apoptotic Bcl-2 gene in vitro using a retrovirus vector. Samples of articular cartilage were obtained from 11 patients with a mean age of 69 years (61 to 75) who were undergoing total knee replacement for osteoarthritis. The Bcl-2-gene-transfected chondrocytes were compared with non-transfected and lac-Z-gene-transfected chondrocytes...
Introduction: The amount of expression of BAX and BCL-2 genes in infertile men’s sperm as well as its association with sperm parameters and DNA fragmentation index is an issue which has not been studied yet. In this research, it is assumed that up-regulation of BAX and downregulation of BCL-2 are directly associated with sperm DNA fragmentation. Methods: After obtaining semen samples from the ...
At high concentrations, the tubule poison paclitaxel is able to kill cancer cells that express Bcl-2; it inhibits the antiapoptotic activity of Bcl-2 by inducing its phosphorylation. To localize the site on Bcl-2 regulated by phosphorylation, mutant forms of Bcl-2 were constructed. Mutant forms of Bcl-2 with an alteration in serine at amino acid 70 (S70A) or with deletion of a 60-aa loop region...
• BIRD-2 is an IP 3 R-derived peptide targeting Bcl-2’s BH4 domain, thereby disrupting R/Bcl-2 complexes. causes caspase-dependent cell death in diffuse large B-cell lymphoma lines. elicits apoptotic independently of the pro-apoptotic Bcl-2-family members Bim, Bax and Bak. BIRD-2-induced relies on mitochondrial Ca 2+ uptake permeability transition pore opening. Anti-apoptotic Bcl-2 critically c...
We searched for proteins that interact with Ras in interleukin (IL)-2-stimulated or IL-2-deprived cells, and found that the transcription factor Aiolos interacts with Ras. The Ras-Aiolos interaction was confirmed in vitro and in vivo by co-immunoprecipitation. Indirect immunofluorescence shows that IL-2 controls the cellular distribution of Aiolos and induces its tyrosine phosphorylation, requi...
objective(s): regarding the presence of many active biological constituents in avicennia marina, the present investigation was carried out to study cytotoxic activity of crude methanol leave extract and column chromatographic fractions of a. marina against mda-mb 231 cell line (human breast cancer cell) and hek (human embryonic kidney cell) line . materials and methods: the anticancer activit...
