As is visible in the violin plot, the mRNA expression levels of YTHDF2, YTHDF1, METTL3, RBM15 and HNRNPC were up‐regulated in glioma compared to normal tissues, whereas the expression levels of ALKBH5, WTAP, YTHDC2, ZC3H13 and METTL14, especially of FTO, were decreased in glioma (Figure 1B). The gene discussed is YTHDC2; the disease is central nervous system cancer.
