GSK3B and nonpapillary renal cell carcinoma: The expression of key molecules in WNT (GSK-3β, β-catenin) and MAPK (JNK, p38, ERK) pathways were detected in ccRCC cell lines with LCOR overexpression by western blot, the results displayed that p-GSK-3β and p-β-catenin had no significant changes, p-JNK was unstable, p-ERK and p-p38 were obviously upregulated (Fig. S5E).
