p16INK4A expression in cervical premalignant and malignant lesions.


p16INK4a is a cyclin-dependent kinase (CDK) inhibitor which decelerates cell cycle by inactivating CDKs that phosphorylate pRb. Human Papillomavirus persistent infection plays an important role on cervical carcinogenesis, mainly by the action of two viral oncoproteins, E6 and E7, which interact with p53 and pRb, respectively. Increasing expression of E6 and… (More)
