摘要染料木黄酮是豆制品中的一种主要成分,在高浓度下,其体外生长抑制作用具有剂量和时间依赖性在4种乳腺癌细胞系中孵育72 h后,IC 50为7.0-274.2 μM(至少185 μM)(DD-762、Sm-MT、MCF-7和MDA-MB-231)和一种人和动物来源的乳腺上皮细胞系(HBL-100);在低浓度(3.7 nM-37 μM)下刺激雌激素受体阳性MCF-7细胞。染料木黄酮暴露的细胞发生凋亡,证实了G2/M期阻滞,随后由一个亚G1级分的细胞周期进程中的外观,并通过一个特征性的细胞超微结构。Bax蛋白表达上调、Bcl-XL蛋白表达下调、caspase-3激活是凋亡级联反应的主要机制。染料木黄酮与鱼油成分二十碳五烯酸(EPA)对人乳腺癌MCF-7细胞(染料木黄酮> 93.2 μM,EPA > 210.9 μM)和MDA-MB-231细胞(染料木黄酮> 176.1 μM,EPA > 609.3 μM)具有协同作用。膳食摄入金雀异黄素与EPA的组合可能有利于乳腺癌的控制。
Abstract Genistein, a prominent isoflavone in soy products, produced dose- and time-dependent in vitro growth inhibition at high concentrations (at least 185 μM) with an IC50 of 7.0–274.2 μM after 72 h incubation in four breast cancer cell lines (DD-762, Sm-MT, MCF-7 and MDA-MB-231) and one breast epithelial cell line (HBL-100) of human and animal origin; it stimulated estrogen-receptor-positive MCF-7 cells at low concentrations (3.7 nM–37 μM). Genistein-exposed cells underwent apoptosis, confirmed by G2/M arrest followed by the appearance of a sub-G1 fraction in cell-cycle progression, and by a characteristic cell ultrastructure. The apoptosis cascade was due to up-regulation of Bax protein, down-regulation of Bcl-XL protein, and activation of caspase-3. Genistein acted in synergism with eicosapentaenoic acid (EPA), a fish oil component, on human breast cancer MCF-7 cells (genistein > 93.2 μM and EPA > 210.9 μM) and on MDA-MB-231 cells (genistein > 176.1 μM and EPA > 609.3 μM). Dietary intake of genistein in combination with EPA may be beneficial for breast cancer control.
