Abstract :

Introduction & Aim: Diabetes may influence the neoplastic processes directly through hyperinsulinemia or indirectly through chronic inflammation and obesity. Resveratrol is an active component of grape, which has been shown to have anti-proliferative and anti-diabetic properties. Based on the association exists between diabetes and breast cancer, this study was designed to investigate the effects of Resveratrol on breast cancer cells (MCF-7) in an in vitro model of hyperinsulinemia. Methods: MCF-7 cells were treated with Resveratrol and/or Doxorubicin (DOX) in a time- and dose-dependent manner. The proliferative response was evaluated by XTT assay and apoptosis was quantified after treatment by annexin V-FITC- propidium iodide (PI) double staining using flow-cytometer. Results: Briefly, our results demonstrated that Resveratrol inhibited the proliferation of MCF-7 cells in a time (24-72 hours) and dose (25-150 �?µM) dependent manner in hyperinsulinemia condition. Moreover, Resveratrol enhanced the cytotoxicity of DOX, so that pre-treatment of MCF-7 cells with low dose Resveratrol equalized cytotoxic effect of 0.1 �?µM DOX to the level achieved when cells were treated with 50 fold higher concentration of DOX (5 �?µM). Also, Resveratrol showed to have apoptotic effect on MCF-7 cells in hyperinsulinemia too. Conclusion: The findings of the present study demonstrated that Resveratrol may be considered as an efficient anti-proliferative agent for antagonizing growth promoting effects of Insulin in breast cancer cell lines.
