INHIBITION OF TELOMERASE ACTIVITY DURING INDUCTION OF HL-60 CELLS BY RETINOID Ro13-7410 %K %X Objective: To investigate the effects of R013-7410 on telomerase activity and cell cycle distribution. Methods: Telomerase activity of HL-60 cells induced by retinoid Ro13-7410 was detected by telomerase PCRELISA- kit. The cell cycle was analyzed by flow cytometry. Results: Telomerase activity declined gradually after 10 .6 mol/L Ro13-7410 treatment, and the inhibition of telomerase activity at day 5 of treatment with Ro13- 7410 was less effective than with Retinoid Acid (RA). DNA flow cytofluorimetric analysis revealed that Ro13- 7410 caused partial cells arrest in the G2/M phase after 4-days treatment. Conclusion: Telomerase activity declined gradually and partial cells were arrested in the G2/M phase after Ro13-7410 treatment. %U https://cjcr.amegroups.org/article/view/1571 %V 11 %N 1 %P 16-18 %@ 1993-0631
