A,B: E-cadherin expression in normal colorectal tissue with the G-allele (A) and GA-allele (B) (each, × 200); C,D: E-cadherin expression in well differentiated CRC with the GA-allele (C) and G-allele (D) (each, × 200); E: E-cadherin expression in poorly differentiated CRC with the GA-allele (× 200); F: Negative control (× 200).
