FIGURE 2.
Expression and distribution of differentially expressed URGs in ccRCC. (A) The differential expression of 204 ubiquitin related genes (URGs) in ccRCC tissue samples (n = 539) compared with normal renal samples (n = 72) is shown in the volcano plot. The red plot represented up-regulated URGs, the green plot represented down-regulated URGs; (B) the differential expression of 204 URGs in ccRCC tissue samples (n = 539) compared with normal renal samples (n = 72) is shown in the heatmap (the statistical method was multiple hypothesis testing).
