Epidemiological studies of postmenopausal women on oral oestrogen replacement therapy (ERT) show a reduction in the risk of developing colon carcinoma. Our previous study demonstrated that 17beta-oestradiol (E2) induced apoptosis in COLO205, a colonic cancer cell line. The aim of this study is to identify the genes important in the E2-induced apoptosis. cDNA array analysis 24h post E2 treatment showed a decrease in mRNA of erbB3 of 92%, K-RAS of 83% and p68TRK-T3 of 98% wherea...
