Mutations are the basis for evolution and the development of genetic diseases.
Especially in cancer, somatic mutations in oncogenes and tumor suppressor genes
alongside the occurrence of passenger mutations have been observed by recent
deep-sequencing approaches. While mutations have long been considered random
events induced by DNA-replication errors or by DNA damaging agents, genome
sequencing led to the discovery of non-random mutation signatures in many human
cancer. Common non-random mutations comprise DNA strand-biased mutation showers
and mutations restricted to certain DNA motifs, which recently have become
attributed to the activity of the AID/APOBEC family of DNA deaminases. Hence,
APOBEC enzymes, which have evolved as key players in natural and adaptive
immunity, have been proposed to contribute to cancer development and clonal
evolution of cancer by inducing collateral genomic damage due to their DNA
deaminating activity. This review focuses on how mutagenic events through
AID/APOBEC deaminases may contribute to cancer development.
