Figure 1. Differential expression of STK4 between tumors and adjacent normal tissues. STK4 expression in multiple tumors and normal tissues based on the TIMER database (A). STK4 expression in ccRCC tissues and normal tissues by using GTEx database and TCGA database (p < 0.001) (B, C). STK4 expression in ccRCC tissues and adjacent tissues (p < 0.001) (D).
