ABSTRACT
Objective To study the effects of cyclooxygenase-2(COX-2) selective inhibitor celecoxib on proliferation and apoptosis of human endometrial adenocarcinoma HEC-1B cell line. Methods Methabenzthiazuron(MTT) assay was used to examine the effects of different concentrations of celecoxib on proliferation of HEC-1B cells.When HEC-1B cells were treated with different concentrations of celecoxib for 24 h,cell cycle and apoptosis were detected by flow cytometry.The expression of COX-2 mRNA was analyzed by RT-PCR. Results MTT results indicated that celecoxib could inhibit HEC-1B cell proliferation in a time-and dose-dependent manner.When HEC-1B cells were treated with different concentrations of celecoxib for 24 h,flow cytometry results showed that the cell percent of(G_(0)/G_(1)) phase increased,S and G_(2)/M phase decreased,and cell apoptosis rate also increased,which was significantly different from that of the control group(P
