YTHDF2 and central nervous system cancer: Recently, strong evidence suggested that m6A RNA methylation regulators including METTL3, METTL14, FTO, and YTHDF2 can regulate the self-renewal, tumorigenesis, growth and progression, and invasion of glioma cell by altering mRNA expression levels of their target genes (e.g., ADAM19, MYC, VEGFA, NCOR2, and HIVEP2) (Cui et al., 2017; Li F. et al., 2019; Dixit et al., 2021; Fang et al., 2021; Huff et al., 2021), which provides a reliable support for the m6A RNA methylation regulator–target gene axes as specific and novel therapeutic targets and clinical prognostic biomarkers in glioma.
