β-Catenin Regulation in Sporadic Colorectal Carcinogenesis: Not as Simple as APC

Figure 2

Nuclear and membrane/cytoplasmic β-catenin immunoexpression for 122 patients. (a) Normal group (n=25). (b) C-IBS (n=30). (c) D-IBS (n=15). (d) CD (n=7). (e) UC (n=12). (f) CRC (n=33). Significant increase β-catenin protein expression from Normal group to CRC, especially nuclear localization. Magnification x40. Scale bar = 200 μm.
