Combinatory effects of phytoestrogens and 17ß-estradiol on proliferation and apoptosis in MCF-7 breast cancer cells

In summary, our in vitro results demonstrate that Gen does not exhibit any antiestrogenic properties. The additive growth stimulatory effects of Gen, Dai and Cou in the presence of E2 are not the result of a stimulation of proliferation; these phytoestrogens, at least in MCF-7 cells, could be characterised as inhibitors of apoptosis.
