P53, BRCA1 and BRCA2 staining in breast tumors. Signals were photographed in breast tissues at × 200. (A) Positive nuclear staining of p53 protein; (B) No obvious nuclear staining was observed over the whole normal breast tissue; (C) Positive nuclear staining of BRCA1 protein; (D) Negative control of BRCA1 staining in a breast tumor. (E) Positive nuclear staining of BRCA2 protein; (F) Negative control of BRCA2 staining in a breast tumor.
