Abstract:
Recently putative catalytic telomerase subunit was identified as telomerase reverse transcriptase (TERT). Several reports showed that TERT expression correlated with telomerase activity. It has also been found that c-myc can induce telomerase activation through TERT expression. We examined expression of TERT and c-myc and their correlation in cervical cancers by reverse transcription-polymerase chain reaction (RT-PCR). It was found that TERT and c-myc expression was observed mostly in malignancies and expression of c-myc was concordant for positivity and negativity with TERT. These results support recent studies that c-myc expression is closely associated with TERT and telomerase activity. c-myc up-regulation may play an important role in activation of TERT and telomerase.
