The immunohistochemical appearance of β-catenin protein expression (A) normal negative rats; (B) cancer rats had elevated β-catenin proteins and severe mucosal injury; (C) reference rats (35 mg/kg 5-FU) had the lowest β-catenin protein expression; (D, E) MF-treated rats (30 and 60 mg/kg MF) showed lower β-catenin proteins (intense brown colour) with less mucosal damage (magnification, ×100).
