Furthermore, integrated analysis of GEO, EGA, and TCGA databases in the Kaplan-Meier Plotter website showed that ALKBH5 mRNA expression was negatively associated with the OS and PFS rates of ovarian cancer patients, OS, FP and PPS rates of gastric cancer patients, and OS and PPS rates of lung cancer patients (Supplementary Figures 4C–E). The gene discussed is ALKBH5; the disease is gastric cancer.
