functionally ‘silent’, it is now known that synonymous mutations drive certain cancers, although the precise mechanisms are poorly understood. Lan et al. now show that synonymous mutations


can disrupt _N_6-methyladenosine (m6A) modifications – the most abundant type of eukaryotic mRNA modification – thereby influencing the stability of tumour suppressor mRNAs. To further


investigate the role of sm6A-DMs in cancer, the authors concentrated on sm6A-DMs found within _CDKN2A_ and _BRCA2_, tumour suppressor genes with exceptionally high observed rates of


sm6A-DMs. Epitranscriptome editing was used to increase or decrease methylation at specific m6A sites within these genes in different cancer cell lines. Upregulation of m6A levels resulted


in an increased abundance of _CDKN2A_ and _BRCA2_ mRNAs, whereas downregulation reduced mRNA levels. These findings underscore the importance of m6A methylation at these sites in the control


of gene expression. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Access Nature and 54 other Nature Portfolio
