In situ hybridization and immunohistochemistry for BNIP3 (original magnification 20×). (a) BNIP3 mRNA expression in a positive tumor and (b) strong BNIP3 protein expression in the same tumor. (c) BNIP3 mRNA negative tumor with presence of positive stromal macrophages as internal controls and (d) absence of BNIP3 protein expression in the same tumor.
