Taurine Attenuates Carcinogenicity in Ulcerative Colitis-Colorectal Cancer Mouse Model

Figure 4

Immunohistochemistry of (a) Ki-67 and (b) PTEN and western blot analysis of (c) cleaved caspase-9. The expression of Ki-67 and PTEN was assessed by avidin-biotin kits with peroxidase-based detection (brown). Nuclei were counterstained with hematoxylin. Original magnifications 100x. (c) Western blot image and relative intensity of cleaved caspase-9 adjusted by β-actin. Graphs represent the average score (bar; SD) of (a) Ki-67 score, (b) PTEN score, (c) cleaved caspase-9. #, ## between model and taurine groups by Mann–Whitney test for score values and Student’s -test for the intensities in the western blot analysis.
