Objective: To investigate the mechanism of Guizhi Fuling Wan in inhibiting the human breast cancer MCF-7 cell by observing its effect on MCF-7 cells and detecting the changes of cell cycle and protein expressions. Method:The human breast cancer MCF-7 cells were cultured in vitro
and 5-Fluorouracil (5-Fu
25 mg·L-1) was used as a positive control medicine to detect the effect of Guizhi Fuling Wan culture on inhibiting the proliferation of the cells under different duration and different doses with the method of 3-(4
5-dimethyl-2-thiazolyl)-2
5-diphenyl-2-H-tetrazolium bromide (MTT). Guizhi Fuling Wan cultures (1.8
2.7 g·L-1) were used for treatment for 48 h. Then the cell cycles was measured by flow cytometry (FCM) in 5-fu group and Guizhi Fuling Wan culture groups; mRNA expression levels of epidermal growth factor receptor (EGFR)
CyclinA2 and cyclin-dependent kinase (Cdk2) were detected by Real-time quantitative polymerase chain reaction (Real-time PCR)
and their protein expression levels were detected by Western blot. Result: Guizhi Fuling Wan can inhibit the proliferation of the human breast cancer MCF-7 cell in a time-dose dependent manner (P<0.05). As compared with blank control group
the number of S phase cells was increased significantly after treatment by 1.8
2.7 g·L-1 Guizhi Fuling Wan for 48 h (P<0.05); the mRNA expression levels of EGFR
Cdk2 and CyclinA2 were significantly reduced (P<0.01); and the protein expression levels of EGFR and Cdk2 were also decreased (P<0.05); however
the expression of CyclinA2 was only deceased in 2.7 g·L-1 group (P<0.05). Conclusion: Guizhi Fuling Wan can inhibit the proliferation of MCF-7 cell in S phase which possiblly related to the expression of CyclinA2
