Abstract
Objective
To evaluate the effect of human telomerase reverse transcriptase (hTERT) gene antisense oligoleoxynucleotide (ASODN) on telomerase activity in K562 cells.
Methods
Telomerase activity was determined by polymerase chain reaction enzyme-linked immunoassay (PCR-ELISA) in K562 cells treated with ASODN and hTERT mRNA expression was detected by reverse transcriptase polymerase chain reaction (RT-PCR).
Results
The hTERT mRNA level was decreased, and telomerase activity was significantly inhibited when the K562 cells were treated with ASODN for 48 h.
Conclusion
It is suggested that hTERT ASODN might specifically inhibit telomerase activity of K562 cells at translation level, and it is further proved that hTERT gene has significant correlation with telomerase activity.
