| Abstract: |
| (Abstract〕 Objective To study the effect of daidzein on the proliferation of endometri-
al carcinoma in uterus and its mechanism. Methods Endometrial carcinoma cell HEC一1B
were cultured in vitro, the influences of genintein in different doses on the proliferation of
HEC一1B cell were detected by MTT method, and the expression of luciferase reportor gene of
ERcx and ERpeffected by ERE were evaluated. Results Daidzein inhibited significantly the
proliferation of HEC一1B cells in vitro(P<0.01) and the effect was streghtened along with the in-
crease of the dose and the prolong of action time. Under the control of daidzein concentration
2080x10-bmol/L, the expression of reporter gene luc was increased compared with control group
(P<0.05) and reached the highest point in the concentration 80x10}mo1/L; the increase of二-
porter gene expression induced by ERp was stronger than that induced luc expression either
through ERcx (P<0.01). Conclusion Daidzein can inhabit the proliferation endometrial carcinoma
through regulating the expression of ERcx or ER(3, and regulating the balance of ERcx/ER(3. |
