CIAPIN1 expression in EOC and paired non-cancerous epithelial tissues by western blotting. ( A) Eight representatives are shown. T, tumor tissue; N, paired non-cancerous epithelial tissue. β-actin was used as an internal control. ( B) Analysis of the CIAPIN1 protein expression in EOCs. CIAPIN1 had high expression in EOC, but low or no expression in paired non-cancerous ovarian epithelial tissues ( Paired EOC). (Statistical significance P < 0.01).
