WNT4 and ovarian serous adenocarcinoma: Renal clear cell carcinoma (RCC; total n = 515, WNT4-high n = 89), lung adenocarcinoma (LuA; total n = 533, WNT4-high n = 57), and serous ovarian cancer (OvCa; total n = 307, WNT4-high n = 39) presented differences in protein signaling by RPPA in WNT4-high tumors (Figure 6B–D, Table S1).
