DUSP2 and benign prostatic hyperplasia: The statistical results presented that the proportion of DUSP2 defined as high expression in BPH tissues was observably higher than that in PCa tissues (Figures 8D, E), revealing that DUSP2 expression was lower in the tumor tissues than in the BPH tissues, and the expression was weakened by carcinoma progression, which was consistent with our bioinformatics analysis
