From: Estrogen receptor α (ERα) mediates 17β-estradiol (E2)-activated expression of HBO1
Expression of HBO1 in human breast cancer. (A) Immunohistochemical staining for HBO1 in benign breast epithelial tissues (magnification: A, 400×). (B) Moderately differentiated breast cancer tissues (brown staining) (magnification: B, 400×). (C) Poorly differentiated breast cancer tissues (brown staining) (magnification: C, 400×). (D) HBO1 protein level in several breast cancer cell lines based on the western blot results.
