Effect of 8-bromum-cyclic adenosine monophosphate on the telomerase activity and dynamics in retinoblastoma cells / 中华眼底病杂志

ABSTRACT

Objective To investigate the effect of the 8-bromum-c yc lic adenosine monophosphate (8-Br-cAMP) on the telomerase activity and changes of cell cycle in retinoblastoma (RB) cells. Methods The cul tured RB cells were divided into the experimental group (8-Br-cAMP) and contro l group. After cultured for 24, 48 and 72 hours in vitro, the telomerase activit y of RB cells was detected by polymerase chain reaction enzyme-linked immunosor bent assay (PCR-ELISA) and the changes of cell cycle were detected by flow-cyt ometry. Results The difference of telomerase activity was sign ificant between the experimental groups and control group (P
