Effects of berberine on proliferation, cell cycle distribution and apoptosis of human breast cancer T47D and MCF7 cell lines
Objective(s):Berberine, a naturally occurring isoquinoline alkaloid, has shown antitumor properties in some in vitro systems. But the effect of berberine on breast cancer has not yet been completely studied. In this study, we evaluated anticancer properties of berberine in comparison to doxorubicin. Materials and Methods: The antiproliferative effects of berberine and doxorubicin alone and in ...
متن کاملRRR-alpha-tocopherol succinate down-regulates oncogenic Ras signaling.
alpha-Tocopherol succinate (TS), an analogue of vitamin E, has growth-inhibitory activity in a wide spectrum of in vitro and in vivo cancer models. Here, we report that modulation of oncogenic Ras is associated with TS activity. TS inhibits the proliferation and induces apoptosis of NIH3T3 cells stably transfected with oncogenic K-Ras and H-Ras, but not NIH3T3 cells expressing empty vector. TS ...
متن کاملThe Inhibitory Effects of Ascorbic Acid, ?-Tocopherol, and Sodium Selenite on Proliferation of Breast Cancer Cell Lines
The role of antioxidants in prevention and treatment of cancers have been reported by several studies. In our investigation we studied the effects of ascorbic acid, ?-tocopherol, and sodium selenite on proliferation of two breast cancer cell lines: T47D (estrogen-receptor positive) and MDA-MB-231 (estrogen-receptor negative). We also used 17-?-estradiol as positive control for proliferation of ...

متن کاملRRR-alpha-tocopheryl succinate-induced apoptosis of human breast cancer cells involves Bax translocation to mitochondria.
Previous studies have identified RRR-alpha-tocopheryl succinate (vitamin E succinate, VES) as a potential chemotherapeutic agent. VES induces human breast cancer cells to undergo apoptosis in a concentration- and time-dependent manner by restoring transforming growth factor beta (TGF-beta) and Fas (CD95) apoptotic signaling pathways, that contribute to the activation of c-Jun NH(2)-terminal kin...
