RASSF1 and breast cancer: Furthermore, the trial also revealed that the drug affected the epigenetic pattern of RASSF-1α, a gene associated with breast cancer, and this effect correlated with the levels of circulating resveratrol.39 These results suggest that resveratrol may act as a chemopreventive agent for breast cancer by influencing the epigenetics of breast cancer associated genes, a finding that needs to be confirmed in future clinical trials.
