Ectopic endometrial tissues were collected from patients diagnosed with endometriosis, and normal endometrial tissues served as controls. ESCs were isolated and cultured. AIF-1 expression was knocked down using siRNA and overexpressed using plasmid vectors. Quantitative real-time PCR (qRT-PCR), western blot analysis, CCK-8 assays, flow cytometry, transwell assays, scratch assays, ATP detection, and mitochondrial membrane potential assays were performed to evaluate gene expression, cell proliferation, apoptosis, invasion, and mitochondrial function. AIF-1 mRNA and protein levels were significantly upregulated in ectopic ESCs compared to controls. Overexpressing AIF-1 elevated cell proliferation and invasion and decreased apoptosis. Additionally, AIF-1 knockdown decreased mitochondrial DNA copy number, membrane potential, and ATP levels, whereas its overexpression had the opposite effects. AIF-1 plays a crucial role in ESCs proliferation, invasion, and migration by modulating mitochondrial function, potentially via the AIF-1 pathway. These findings suggest that targeting AIF-1 could be a novel therapeutic approach for managing endometriosis.\nConflicts of Interest\nThe authors declare no conflicts of interest.\nData Availability Statement\nThe data used to support the findings of this study are available from the corresponding author upon request.","source_license":"public-domain-us","license_restricted":false}
