Loss of function mutations in CDKN1A are permissive for APOBEC3-induced mutagenesis in urothelial carcinoma.

abstract
Mutagenic mechanisms that shape the genomic landscape and dysfunction of DNA repair converge to promote bladder tumorigenesis. A recent study by Arnoff and El-Deiry highlights the unique interactions between CDKN1A loss of function mutations, which play a key role in cell cycle regulation, modulating DNA repair, and inducing cell apoptosis and senescence, and APOBEC3-induced mutagenesis, the predominant contributor of mutations in urothelial carcinoma.
