ABSTRACT
Objective To investigate effect on telomerase activity of Hep-2 cells treated by anticancer drugs(hydroxycamptothecine, cisplatin and cytoxan).Methods By MTT method,we measured the 50% inhibitory concentration(IC 50 ) at 72h,and compared to untreated control cells. Telomerase activity of Hep-2 cells treated by the drugs in different concentration based on IC 50 for different time was observed by Telomeric Repeat Amplification Protocol with ELISA(TRAP-ELISA).Results Hydroxycamptothecine and cytoxan could inhibit proliferation of Hep-2 and down-regulate telomerase activity of Hep-2 cell. However, cisplatin promoted proliferation of Hep-2 and up-regulated telomerase activity of Hep-2 cell.Conclusions Hydroxycamptothecine and cytoxan could down-regulate telomerase activity of Hep-2 cell by direct or indirect pattern, which may correlate with drug concentration and time-dependent pattern.Cisplatin could up-regulate telomerase activity of Hep-2 cell, which mechanism is not clear.
