Impact of HPV E5 on viral life cycle via EGFR signaling

Publication date: Available online 11 December 2019Source: Microbial PathogenesisAuthor(s): Naureen Ehsan Ilahi, Attya BhattiAbstractOncoprotein E5 is gaining popularity with time as the third transforming protein of Human Papillomavirus (HPV). Extensive proliferation is the distinguished feature of developing cancers, and E5 is able to stimulate keratinocytes proliferation via upregulation of EGFR signaling pathway. Thus E5 is thought to indirectly contribute to the completion of the viral life-cycle by generating the adequate cellular environment. By amplifying EGFR signaling E5 delays differentiation and allows hyperproliferation of keratinocytes which otherwise would have followed a normal differentiation pathway. Thus exploring the mechanisms by which HPV E5 regulates signaling by EGFR receptors in detail suggest new ways of inhibiting HPV-mediated disease progression.
