High-risk human papillomavirus (HR-HPV) persistent infection is responsible for the development of the majority of cervical cancers. The therapy against HPV-associated cancer requires knowledge of the viral gene expression mechanisms. In this study, the polyadenylated polycistronic transcripts containing full-size E1ORF and produced from the early P14 promoter were detected for the first time in cervical...
Human papillomavirus (HPV) is well recognized as a causative agent for anogenital and oropharyngeal cancers, however, the biology of HPV infection at different mucosal locations, specifically the oral cavity, is not well understood. Importantly, it has yet to be determined if oral tissues are permissive for HPV infection and replication. We investigated for the first time the titers, infectivity,...
Productive replication of human papillomaviruses (HPV) is restricted to the uppermost layers of the differentiating epithelia. How HPV ensures an adequate supply of cellular substrates for viral DNA synthesis in a differentiating environment is unclear. Here, we demonstrate that HPV31 positive cells exhibit increased dNTP pools and levels of RRM2, a component of the ribonucleotide reductase (RNR)...
