Effect of exemestane on the invasive growth of endometrial carcinoma HHUA cells

To investigate the effect of exemestane on HHUA human endometrial carcinoma cells.The HHUA human endometrial carcinoma cells were treated with various concentrations of exemestane, and its effects on cell growth and apoptosis were investigated in vitro. The cell apoptosis was analyzed by flow cytometry and RT-PCR was used to investigate the expression of CD44s. The invasion ability of HHUA human endometrial carcinoma cells which treated with exemestane were assessed using transwell chamber model.At increasing doses of exemestane, a simultaneous increase in apoptotic subpopulations was detected when compared with group A (p0.05); the CD44s expression was found to be suppressed after the exemestane treatment. The decrease was a dose-dependent with exemestane treatment.6x10⁸ mol/L exemestane is an optimal dose to inhibit the expression of CD44s mRNA and inhibit the invasive growth of the endometrial carcinoma HHUA cells.
