CK2 control of human papillomavirus life cycles.

Human papillomaviruses are causative agents in around 5 % of all cancers, and in a number of other human diseases. While prophylactic vaccines will alleviate the HPV disease burden on future generations, there are currently no therapeutic anti-viral strategies for combating HPV infections or lesions. HPV induce the proliferation of infected epithelial cells and modulate the host differentiation response, and both of these controls are required for a successful viral life cycle. Enhanced understanding of viral-host interactions during the viral life cycle will identify potential novel anti-viral strategies for therapeutic development. This minireview will summarize the critical role of the host enzyme CK2 in regulating the function of the viral proteins E1, E2 and E7; such control makes CK2 a critical enzyme for regulating HPV life cycles. Therapeutic strategies blocking CK2 function to combat HPV infections and treat HPV diseases will be described.
