摘要
AIM:To explore the effect of antisense oligocleoxynucletide(As-ODN)of telomerase RNA on telomerase activity and cell apoptosis in human colon cancer.RESULTS:The telomerase activity in SW480 cells transfected with 1.0μmol/L of As-ODN for 2-5days,was significantly decreased in a time-dependent manner,and the cells underwent apoptosis.The missense ODN(Ms-ODN)and the control group transfected with SW480 cells did not show these changes.CONCLUSION:As-ODN can specifically inhibit the telomerase activity of SW480 cells and induce apoptosis.
