Abstract:
OBJECTIVETo investigate the effect of hTERT antisense oligodeoxynucleotide on telomerase activity in bladder cancer cells.
METHODSAntisense phosphorothioate oligodeoxynucleotide (AS PS-ODN) was synthesized and purified. Telomerase activity was measured by telomerase PCR ELISA kit. hTERT mRNA expression was detected by reverse transcription-polymerase chain reaction (RT-PCR), and hTERT protein by immunohistochemistry and flow cytometry.
RESULTSTelomerase activity was decreased in T24 cells 48 h after treatment with AS PS-ODN, and was significantly inhibited at 72 h.
CONCLUSIONAS PS-ODN can significantly inhibit telomerase activity by down-regulating hTERT mRNA and protein expression in bladder cancer cells.
