The chemomodulatory effects of resveratrol and didox on herceptin cytotoxicity in breast cancer cell lines.

ABSTRACT: Herceptin is considered an essential treatment option for double negative breast cancer. Resveratrol and didox are known chemopreventive agents with potential anticancer properties. The aim of the current study is to investigate the influence of resveratrol and didox on the cytotoxicity profile of herceptin in HER-2 receptor positive and HER-2 receptor negative breast cancer cell lines (T47D and MCF-7 cell lines, respectively). The IC50's of herceptin in T47D and MCF-7 were 0.133 ± 0.005 ng/ml and 23.3795 ± 1.99 ng/ml respectively. Equitoxic combination of herceptin with resveratrol or didox in T47D significantly reduced the IC50 to 0.052 ± 0.001 and 0.0365 ± 0.001 ng/ml, respectively and similar results were obtained in MCF-7. The gene expression of BCL-xl was markedly decreased in T47D c
