Abstract
The antiandrogen flutamide (FLU) has been reported to exert antiproliferative action on both male and postmenopausal breast cancer and to inhibit growth of chemically induced rat breast cancer. We studied the effects of various concentrations of FLU on the growth of the ER+, AR+ and PR+ MCF-7 and the ER-, AR- and PR- MDA-MB-231 human breast cancer cell lines. The growth of MCF-7 cells in both steroid free and estradiol supplemented media was inhibited by FLU. MDA-MB-231 cell growth was not affected by FLU. Our data show a direct inhibitory action of FLU on human breast cancer cells and suggest a different susceptibility to the antiproliferative action of FLU, which seems to be related to the steroid receptor status.
