The correlation between telomerase activity and Bax/Bcl-2 ratio in valproic acid-treated MCF-7 breast cancer cell line
Objective(s):Valproic acid (VPA), a drug used in the treatment of neurological disorders, has been shown to have cytotoxic effects on cancer cells through different mechanisms. Telomerase, a ribonucleoprotein reverse transcriptase, is responsible for elongation of the telomere and is activated in cancers. A relation between telomerase activity and resistance to apoptosis has been established. T...
متن کاملTelomerase activity and Bcl-2 expression in non-small cell lung cancer.
Bcl-2 and p53 are the most relevant proteins in apoptosis and tumor development. Telomerase functions in the maintenance of telomeres and is indispensable for immortalization. Bcl-2 was reported as a direct modulator of telomerase activity, and a correlation between p53 and telomerase activity was reported. The aim of this study was to determine the relationships between Bcl-2, p53, and telomer...

متن کاملeffects of treatment with platinum azidothymidine and azidothymidine on telomerase activity and bcl-2 concentration in hepatocellular carcinoma- induced rats
background: telomerase activity increases in cancer cells. bcl-2 is an antiapoptotic factor that its concentration grows in many cancer cells including hepatocellular carcinoma cells. in this study, an attempt was made to investigate the effects of a new synthetic compound, platinum azidothymidine (pt-azt) on treatment of rats with hepatocellular carcinoma (hcc) and to compare its effects with ...
متن کاملEstrogen modulates Bcl-2 family proteins in ischemic brain injury.
Estradiol acts as a neuroprotective factor against brain injury. This study investigated whether estradiol modulates the Bcl-2 family proteins in ischemic brain injury. Adult female rats were ovariectomized and treated with estradiol prior to middle cerebral artery occlusion (MCAO). Brains were collected 24 hr after MCAO, and infarct volumes were analyzed. Estradiol significantly reduces the in...
