Nucleotide Substitution Biases in Related Cancer Driver Genes.

ABSTRACT: Nucleotide substitutions are common in cancer cells, and they occur in both protein coding regions and non-coding regions (5' and 3' UTRs and introns). Although substitutions in non-coding regions have the potential to alter gene expression, it is the alteration of coding regions that affects protein function and has the most drastic effect on cellular transformation. Mutations in certain genes (e.g., TP53, KRAS) are common to nearly all cancers, but most cancers are characterized by specific gene mutation signatures. In this report, we investigated nucleotide substitution signatures in coding regions of the top 25 most frequently mutated genes in multiple human cancers. The goal was to examine whether unique nucleotide substitution biases are associated with various cancers.
