扶正祛邪方抑制表观遗传调控蛋白EZH2对卵巢癌细胞的影响及其机制OACSTPCD

Objective To investigate the effect of Fuzhengquxie prescription on the proliferation,apoptosis,invasion,and migration of ovarian cancer cells and its associated mechanism.Methods After Fuzhengquxie prescription was applied to human ovarian cancer SKOV3 cells,the effects on cell proliferation,apoptosis,invasion,and migration were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide,cell cloning,cell scratch,and Transwell assay experiments.Quantitative reverse transcription-polymerase chain reaction(qRT-PCR)and Western blotting were used to determine the expression levels of the negative epigenetic regulatory protein,EZH2;its related protein,E-cadherin;and the apoptosis-related proteins,Bax and Bcl-2.Results Fuzhengquxie prescription inhibited the growth rate of SKOV3 cells in a concentration-and time-dependent manner,and significantly inhibited the proliferation,invasion,and migration of SKOV3 cells.Western blotting and qRT-PCR results showed that Fuzhengquxie prescription combined with GSK126 inhibited the transcription of EZH2and Bcl-2,promoted the transcription of Baxand E-cadherin,down-regulated the expression of EZH2 and Bcl-2 proteins,and promoted the expression of Bax and E-cadherin proteins.Conclusion Fuzhengquxie prescription inhibited the proliferation,invasion,and migration of SKOV3 cells and induced their apoptosis.It may be involved in regulating the E-cadherin-mediated proliferation,invasion,and migration of ovarian cancer cells by inhibiting the epigenetic regulatory protein EZH2,and regulating the apop-tosis of ovarian cancer cells mediated by Bcl-2 and Bax.
