Expression of the G protein-coupled estrogen receptor (GPER) in endometriosis, in normal endometrium and in the positive control. (A-C) Expression of the G protein-coupled estrogen receptor (GPER) in ovarian endometriosis with strong cytoplasmic and partial nuclear expression in the epithelium and strong nuclear expression in the stroma (A, 200Ă—; B, 400Ă—), compared to normal endometrium with positive nuclear and lack of cytoplasmic GPER expression (C, 200Ă—). (D-E) GPER expression from breast carcinoma as a positive control with (D, 200Ă—) strong cytoplasmic and negative nuclear GPER expression, as well as with (E, 200Ă—) weak cytoplasmic and strong nuclear GPER expression.
