FTO and gastric cancer: We used the GEPIA database to analyze and found that FTO expression was significantly elevated in GC tissues (Fig. 6A, B), and then we analyzed the Kaplan–Meier Plotter database to correlate FTO expression levels with overall survival (OS) of GC patients and found that high FTO expression tended to predict poor survival prediction (log-rank p < 0.001) (Fig. 6C).
