The expression levels of KLF7/ IL-6/ p21/ Ki67 in tumor tissues of patients with PCa. A-D Immunohistochemistry was used to detect the expression level of KLF7/ IL-6/ p21/ Ki67 in BPH tissues(up) and tumor tissues with PCa(down) (100 × , 200 ×). E–H Immunohistochemical score of KLF7/ IL-6/ p21/ Ki67. t test, *P < 0.05, **P < 0.01, ***P < 0.001 the difference was statistically significant
