Immunohistochemistry of BRCA1 and BRCA2 protein expression in gastric cancer tissues. (A) Strong positive BRCA1 staining in the cytoplasm and nuclei, and (B) positive BRCA2 staining in the cytoplasm of gastric adenocarcinoma cells. (C) Negative BRCA1 staining in the cytoplasm and nuclei, and (D) negative BRCA2 staining in the nucleus and cytoplasm of gastric adenocarcinoma cells. (E) Positive BRCA1 staining in the cytoplasm, and (F) positive BRCA2 staining in the cytoplasm of chronic gastritis cells. Magnification, ×400 (scale bar, 50 µm). BRCA1/2, breast cancer type 1 and 2 susceptibility protein.
