FTO and central nervous system cancer: In this study, we find that the m6A RNA methylation eraser FTO is dramatically downregulated in glioma samples and cell lines, particularly in intermediate and core regions and hypoxia-challenged glioma cells.In vitro, FTO overexpression inhibits the hypoxia-induced capacities of glioma cells to proliferate, migrate and invade, and decreases the percentage of cells with m6A RNA methylation.In vivo, FTO overexpression inhibits tumor growth in the xenograft model and decreases the protein levels of migration markers, including Vimentin and Twist.
