Methods
Ectopic endometriotic and eutopic endometrial stromal cells (SCs) were isolated and maintained in culture. PGC-1α was either overexpressed in the cells or knocked down using siRNA. The expression of PGC-1α and other factors during endometriosis was examined using real-time PCR and western blotting, cell proliferation was measured using Cell Counting Kit-8 (WST-8) assays and transcriptional activity was assessed using luciferase reporter assays.
