It has been recently recognized that METTL3 expression is correlated with the expression of Delta-Like Ligand 3 (DLL3), Notch Receptor 3 (NOTCH3), and Hairy and Enhancer of Split (HES1) in gliomas, indicating that METTL3 can directly activate the Notch signaling and increase the expression of downstream HES1 supporting glioma progression [72, 73]. This evidence concerns the gene NOTCH3 and central nervous system cancer.
