Immunohistochemistry in the primary tumor tissues for Nrf2. a (× 200): In the tumors with C/C genotype for rs6721961 SNP of the Nrf2, lower histological grade, some tumor cells showed weak reaction for anti-Nrf2 antibody (lower expression). b (× 200): In the tumors with C/A genotype, higher histological grade, much of the tumor cells showed moderate to strong brown staining (higher expression)
