Detection of CIAPIN1 expression in freshly obtained CRC tissues Western blot analysis. (A) CIAPIN1 expression level in cancerous and adjacent normal tissues from the same patients. (B) CIAPIN1 expression level in poorly, moderately, and well-differentiated cancer tissues. (C) CIAPIN1 expression in cancer tissues with different TNM stages. β-Actin staining was used as a control for equal protein loading.
