Using the GEPIA2 database, we further analyzed the correlation between WDR62 and MKK4/MKK7 in ovarian cancer, as shown in Fig. 5D, WDR62 was positively correlated with MKK4 (R = 0.45, P < 0.05) and MKK7 (R = 0.34, P < 0.05) in ovarian cancer. This evidence concerns the gene MAP2K4 and ovarian cancer.
