Methods: Assaying the expression of telomerase and thetype of HPV in damaged skin of 42 CA patients and normalskin of 30 healthy control individuals through telomeraserepeat amplification protocol (TRAP) and polymerase chainreaction (PCR). Results: In all the normal skin controls, PCR for HPV wasnegative and only 16.7% of samples were positive for TLMAexpression; in CA lesions, HPV testing was positive in all (32cases were low-risk, 3 were high-risk, and 7 were of mixedtype) and all were positive for TLMA expression. Conclusion: TLMA may be activated by HPV infection,and in turn cause the hyperplasia of epidermal cells. It wasalso indicated that HPV, especially high risk types, canactivate TLMA. The activation of TLMA may play animportant role in abnormal hyperplasia and carcinomatouschanges in CA lesions.展开更多
