2. Figure 1
Expression of ERα and ERβ is increased in both ectopic endometrium and peritoneal tissue of patients with endometriosis in comparison with normal subjects. Relative expression of ERα (A) and ERβ (B) genes in normal, eutopic, and ectopic endometrium. mRNA quantification of ERα (C) and ERβ (D) in uninvolved peritoneal tissue from control individuals and patients with endometriosis. *P<.05, **P<.001, vs. normal tissue; νP<.05, ννP<.0001, vs. eutopic endometrium. Data represent mean ± SEM.

3. Figure 2
Augmented expression of estrogen-regulated genes implicated in proliferation in ectopic endometrial tissue. Expression of E2-regulated genes was analyzed by qRT-PCR and normalized to GAPDH. c-myc (A), cyclin D1 (B), and GREB1 (C). *P<.05, **P<.001, ***P<.0001 vs. normal endometrium; νP<.05 vs. eutopic endometrium. Data are presented as mean ± SEM.

4. Figure 3
Immunohistochemical localization of estrogen-regulated genes in normal, eutopic, and ectopic endometrium. c-myc expression in normal endometrium (A), eutopic (B), and ectopic endometrial tissue from subjects not taking contraceptives (C). Cyclin D1 expression in normal endometrium (D), eutopic (E), and ectopic endometrial tissue (F). GREB1 expression in normal endometrium (G), eutopic (H), and ectopic (I) endometrial tissue from subjects not taking contraceptives. A picture at ×40 magnification is shown in the insert. Negative control for normal endometrium (J), eutopic (K), and ectopic endometrial tissue (L). A representative of six biological replicates is shown.
