Relative telomerase activity in human gliomas and cell lines. a Telomerase activity was detected by TRAP assay, and all four cell lines exhibited high TA. Thirty-four of 38 (89.5%) GBMs (b), 17 of 23 (73.9%) ODMs (c), and 16 of 35 (35.7%) OAMs (d) exhibited high TA. e The high telomerase activity of human gliomas was significantly consistent with the expression of hTERT+β transcript
