Abstract:Objective: To study the effects of the traditional Chinese drugs,Shuganyishen,on Ishikawa cell line. Method: Rat blood serum was prepared by using Chinese drugs serum pharmacology method,in which,Shuganyishen was contained or not contained. Ishikawa cells were subjected into five groups: ① normal cells group (NCG),②rat blood serum without Shuganyishen group (NSGG) as negative control,③Shuganyishen group(SGG),④Cisplatin group (DDPG) as positive control,and ⑤Shuganyishen with Cisplatin group (S&CG). MTT assay was used to evaluate the inhibition effect on cell growth in each group. The mRNA expression of estrogen receptor α and β (ERα and ERβ) in each group was detected by RT-PCR. Result: Effective inhibition of cell growth was found in the groups of SGG and S&CG,respectively (P<0.05),which had no significant difference from positive control by MTT. The mRNA expression of ERβ was slightly going up,while the expression of ERα was hardly effected in SGG by RT-PCR. Interestingly in S&CG,the mRNA expression of ERα was significantly down-regulated (P<0.05),but the mRNA expression of ERβ remained no change. As the positive control,the mRNA expression of ERα and ERβ was significantly down-regulated in DDPG (P<0.05). Conclusion: Traditional Chinese drugs,Shuganyishen,may inhibit Ishikawa cell growth and had no effects on the expression of ERα,furthermore,can reverse the inhibition of ERβ expression by Cisplatin.
