ANGPTL2 and polycystic ovary syndrome: However, we only preliminarily explored the mechanism of ANGPTL2 and miR-124-3p in PCOS by predicting the binding sites between the two using the StarBase database and verifying the targeted relationship in KGN cells, but the specific molecular mechanism by which miR-124-3p affects the onset and development of PCOS through ANGPTL2 remains unclear and requires further investigation.
