ABSTRACT
Objective To study the effect of ribozyme mediated inhibition on telomerase activity and cell(proliferation) of GBC-SD cells.Methods According to the hTR template two wings region sequence,the hammerhead ribozyme gene sequence was synthesized in vitro.Then,it was engineered into the eukaryon(expression) vector pTriEx-4.Lipofectamine was used to transfect the carcinoma of gallbladder.The inhibition of telomerase activity and cell proliferation in GBC-SD cell was observed,and compared with control group.(Results) Compared to control group,ribozyme can significantly inhibit telomerase activity and cell proliferation of GBC-SD cell.After ribozyme action,the cell ratio of G_0/G_1 markedly increased,and the cell ratio of S phase markedly decreased.Cellular cleavage and proliferation was markedly inhibited.The apoptosis rate was 17.10% and 31.01% on day10 and day13 after ribozyme action.Conclusions Ribozyme can inhibit(telomerase) activity of GBC-SD cells effectively and induce cell apoptosis.
