Human Telomerase Reverse Transcriptase Expression In Oral Carcinogenesis - A Preliminary Report, Kumar S. K. S., Rosnah Binti Zain, Ismail S. M., Cheong S. C.

Prof. Dr. Rosnah Binti Zain

Human telomerase reverse transcriptase (hTERT), the catalytic subunit of telomerase, is strongly associated with telomerase activity implicated in cellular immortalization and tumorigenesis. In situ detection of hTERT will aid in determining the localization of telomerase positive cells. The aim of this study was to detect hTERT protein expression in multistep oral carcinogenesis using paraffin embedded tissue samples, and to study the relationship of hTERT expression with different histological stages in oral carcinogenesis. Normal (n=4), hyperplastic (n=4), dysplastic (n=4) and neoplastic (n=10) oral epithelia representing different histological stages in oral carcinogenesis were included in the study. hTERT protein detection was done …
