Death decoy receptor overexpression and increased malignancy risk in colorectal cancer

Figure 1 Immunohistochemical detection of human epidermal growth factor receptor 2 and death decoy receptor expression in colorectal cancer. Serial-section specimens from one representative case are shown (× 200). A: Human epidermal growth factor receptor 2 (HER2)-positive tumor section, scored as 2+ (arrow); B: HER2-positive tumor section, scored as 3+ (arrow); C: Death decoy receptor-positive tumor section showing staining in > 10% of the tumor cells (arrow).
