Low-grade slightly elevated and polypoid colorectal adenomas display differential β-catenin-TCF/LEF activity, c-Myc, and cyclin D1 expression

Figure 2 Gross apoptosis and proliferation indices. A: Slightly elevated lesions demonstrated a significantly lower apoptosis index relative to polypoid lesions. B: There was no significant difference in the Ki-67 labeling index between the two lesion types. ^aP < 0.05, slightly elevated vs polypoid.
