Employing the UTUC (n = 47) and UBUC (n = 411) datasets in the TCGA database, we appraised the top 194 overlapping transcripts (Figure 5A) that show positive correlations with SFRP2 between UTUC (Supplementary Table 1) and UBUC (Supplementary Table 2). The gene discussed is SFRP2; the disease is renal pelvis/ureter urothelial carcinoma.
