IFN-γ‒Induced APOBEC3B Contributes to Merkel Cell Polyomavirus Genome Mutagenesis in Merkel Cell Carcinoma
28 Dec 2021
Abstract excerpt
Merkel cell polyomavirus (MCPyV) is the causative agent of an aggressive skin tumor, Merkel cell carcinoma. The viral genome is integrated into the tumor genome and harbors nonsense mutations in the helicase domain of large T antigen. However, the molecular mechanisms by which the viral genome gains the tumor-specific mutations remain to be elucidated. Focusing on host cytosine deaminases APOBEC3s, we find that...
