Objective:To study cytotoxic effects of Toremifene (TOR), and synergistic effect of TOR combined with vinorelbine (NVB) on human lung adenocarcinoma cancer cell lines A549.To probe it's underlying mechanisms.Which might be expected to provide the new chemotherapy methods of lung cancer, Methods:Human lung adenocarcinoma cell lines A549 were devided into blank group (culture),control group (cells),experiment group(cells+different factor) .Expr iment were divided into TOR group,anti-tumor drugs group,and combine group.The cytotoxic effects on A549 were measured by MTT assay,and morphologic changes of A549 after treatment of agentswere were detected by HE stains,and morphologic changes of apoptosis and apoptosis rate (AR) were detected by In situ cell Death Dectection kit,pod. Result:TOR (≥5umol/L) could inhibit the growth of A549 cells,TOR combined with NVB showed significant synergistic anti-tumor effects on A549 cells,the inhibitory rate(IR)were higher than that of anti-tumor drugs alone, The IR were also increased with increasesing of the agents concent ration.TOR (5,10umol/L) didn't induce on... |
