Evidence for APOBEC3B mutagenesis in multiple human cancers.

Abstract excerpt

Thousands of somatic mutations accrue in most human cancers, and their causes are largely unknown. We recently showed that the DNA cytidine deaminase APOBEC3B accounts for up to half of the mutational load in breast carcinomas expressing this enzyme. Here we address whether APOBEC3B is broadly responsible for mutagenesis in multiple tumor types. We analyzed gene expression data and mutation patterns,...
