ZSWIM4 and neoplasm: First, by analyzing the data from the GEPIA database, we found that ZSWIM4 was overexpressed in OC tumor tissues (Additional file 1: Fig. S1A), and that poor prognosis was associated with high ZSWIM4 expression (Additional file 1: Fig. S1B).We consistently confirmed poorer prognosis in patients with OC showing ZSWIM4 overexpression using the Kaplan–Meier plotter website (Additional file 1: Fig. S1C, D).
