Abstract
Objective To investigate the effects of 2-Methoxy-6-acetyl-7-methyljuglone (MAM) extracted from Polygonum cuspidatum (Hu Zhang) on the proliferation of human breast cancer MDA-MB-231 cells and its possible mechanisms. Method Human normal liver cellLO2andhumanbreastcancercells(MDA-MB-231andMDA-MB-468)wereculturedin vitro.TheeffectsofMAMonthegrowthin-hibition ratio of cells were evaluated by the Cell Counting Kit-8 (CCK8). The effects of MAM on the apoptosis of MDA-MB-231 cells were detected through morphological observation by Hoechst33258 staining. The effects of MAM on the cell cycle of MDA-MB-231 cells were detected through flow cytometric analysis (FCM). The expressions of related proteins were analyzed by western blot. Results MAM signifi-cantly inhibited the growth and proliferation of MDA-MB-231 cells in a dose-and time-dependent manner. Typical morphological change of apoptosis occurred in MDA-MB-231 cells when treated with MAM for 24 h, and increased cells were arrested in G2/M phase. Western blot showed the expressions of Cdk1 and CyclinB1 were depressed, and protein expression of p-Cdk1 (Thr14) was up-regulated (P﹤0.05). Conclusion MAM inhibits the proliferation of MDA-MB-231 cells through G2/M cell cycle arrest induction, which is mediated by depres-sion of Cdk1-CyclinB1 complex.关键词
