SOX4 and nonpapillary renal cell carcinoma: Figure 1(a) revealed the pheatmap of all differentially expressed SOXs. Among them, SOX4/5/6/13/15/30 were distinctly lower in ccRCC specimens than in noncancerous specimens (Figures 1(b)–1(d), 1(i), 1(j), and 1(m)), while SOX7/9/11/12/18/21 were highly expressed in ccRCC compared with nontumor specimens (Figures 1(e)–1(h), 1(k), and 1(l)).
