To sum up, our results suggest that WDR62 may be a potential biomarker for ovarian cancer, and WDR62 is highly expressed in ovarian cancer and is closely associated with poor prognosis of ovarian cancer patients.WDR62 promotes the proliferation of ovarian cancer by regulating the cell cycle, and it is hypothesized that WDR62 may influence ovarian cancer progression by interacting with MAPK8 to mediate the JNK signaling pathway and thus modulate the cell cycle. Here, WDR62 is linked to ovarian cancer.
