Abstract:
Objective To observe the inhibitory effect of LaCl_3 on the growth of human hepatocellular carcinoma cell lines SMMC-7721 and its mechanism.Methods The cells were treated with different doses of LaCl_3 and the growth curve,colony inhibitory rates,the levels of AFP of cultured cells were detected at 1,3,5 and 7 days after they were dealed with LaCl_3.The changes of cell cycle were detected by flow cytometry and the expressions of cell cycle protein CyclinD_1,PCNA,CDK_4 and P16 were observed by immunocytochemistry staining.Results MTT test showed that SMMC-7721 cell proliterating activity was obviously inhibited by LaCl_3 in a time and dose related manner at concentrations of 0.50 and 1.00 mmol?L~(-1).The colony forming inhibitory rate of 0.10,0.50 and(1.00 mmol?L~(-1))LaCl_3 were 51%, 67% and 97% (P
