Objective:
To explore the relationship between gene expression of human telomerase reverse transcriptase (hTERT) and its clinical characteristics in leukemia.
Methods:
The protocol of RT-PCR was used to detect the hTERTmRNA expressing levels in peripheral blood samples from leukemic patients under primary treatment(n=42), in complete remission(n=21), with recurrent leukemia (n=4); and from normal subjects (n=5), respectively.
Results:
The positive percentage of hTERTmRNA expression was 73.81% for the primary treatment cases, and 19.05% for the complete remission cases. All of the recurrent cases gave positive results. One of the normal controls presented low level of hTERTmRNA expression. The expressing level of hTERTmRNA in primary treatment cases was 0.64+/-0.21, in complete remission leukemia 0.31+/-0.16, in recurrent cases 0.84+/-0.09, and in normal controls 0.10.
Conclusion:
The activation of telomerase may be an essential factor in the development of leukemia and usually be the late event in its progression. As an indicator of leukemia cell, the detection of hTERT mRNA may be used in clinical analysis, disease monitoring and prognosis judgement.
