We observed the high expression levels of METLL8, METLL2A, TRMT112, METTL2B, GTPBP3, METTL6, and NSUN4 in cells in the S, G2M, and G1 phases, which were similar for astrocytes, glioma cells, and oligodendrocytes (Fig. 2A,C,F). This evidence concerns the gene GTPBP3 and central nervous system cancer.
