標題: | Growth inhibition of human endothelial cells by the phyto-oestrogen biochanin A, a metabolite of genistein | 作者: | JIH-TAY HSU | 關鍵字: | Cell proliferation; Endothelial cells; Phyto-oestrogen | 公開日期: | 2001 | 卷: | 85 | 期: | 5 | 起(迄)頁: | 615-620 | 來源出版物: | British Journal of Nutrition | 摘要: | This study examined the growth regulatory effects of a phyto-oestrogen, biochanin A, on a transformed human endothelial cell line ECV304 in vitro. Biochanin A was found to inhibit cell proliferation in a dose-dependent fashion and this effect was influenced by the concentration of serum present in the culture medium. In the absence of serum, the calculated IC50 of biochanin A was 0.18 ± 0.1 μM compared to an IC50 of 35 ± 5 μM at 10 % serum. At low cell density, the growth inhibitory effects of biochanin A were more evident than at high cell density. Co-administration of a synthetic oestrogen diethylstilboestrol with biochanin A did not suppress the growth regulatory effects of biochanin A treatment. We conclude that biochanin A inhibits the cell proliferation of human endothelial cells at concentrations that are physiologically achievable in vivo and that this effect may play an important role in the cancer-preventing activity of the phyto-oestrogens. |
