In summary, HPV16 mRNAs are methylated in HPV16-infected tonsillar cancer cells and overexpression of m6A-“writer” METTL3, m6A-“eraser” ALKBH5 and the m6A-“reader” YTHDC1 affected HPV16 mRNA splicing, suggesting that m6A plays an important role in the HPV16 gene expression program, at least in cancer cells. This evidence concerns the gene YTHDC1 and cancer.
