Inverse expression of steroidogenic factor 1 (SF-1) and miR-370-3p in endometriosis determined by quantitative RT-PCR. A and B: SF-1 mRNA levels were upregulated (A) in the tissue of endometriotic lesions and miR-370-3p was downregulated (B) in serum from patients with endometriosis compared with controls. C and D: for primary cells SF-1 mRNA levels were upregulated (C) while miR-370-3p was downregulated (D) in endometriotic cyst stromal cells (ECSCs) compared with eutopic endometrial stromal cells (EUSCs) and normal endometrial stromal cells (NESC)s. Each bar represents the means ± SE for data from 3 individual experiments, and each experiment was performed in duplicate. *P < 0.05, statistical significance, control vs, endometriosis ECSCs vs EUSCs. **P < 0.01, statistical significance, control vs, endometriosis, NESCs vs. EUSCs. ***P < 0.001, statistical significance compared with NESCs and EUSCs.
