Of the 52 cases with tumor and non-tumor paired samples, TSPX was downregulated in 44 cases (83%) of prostate cancer, as compared to the adjacent normal specimens, and was up-regulated in 6 cases (11%) (Figure 1B and Table 1), indicating that TSPX was significantly downregulated in prostate cancer of TCGA dataset (Wilcoxon matched pair test P-value < 0.0001). This evidence concerns the gene TSPYL2 and prostate carcinoma.
