Expression of β-catenin in the primary and metastatic tumors. (A) Immunohistochemistry for β-catenin was performed using the primary tumor sections. (a, b) the control group. (c, d) Gen/meta(-) subgroup is the genistein/metastasis(-) subgroup. Magnification: (a, c) × 40; (b, d) × 4. (B) Immunohistochemistry for β-catenin was performed using the sections of the lung (e) and liver (f) in the control group. Magnification: ×40. (C and D) The β-catenin-labeling index (C) and β-catenin-labeling score (D) were determined. Gen/meta(-) subgroup is the genistein/metastasis(-) subgroup. Values given are the means ± SE for eight tumor specimens in the control group and for six tumor specimens in the genistein/metastasis(-) subgroup.
