FOXL2 and primary ovarian failure: To select for previously unknown players controlling folliculogenesis, we focused on proteins that were bound with FOXL2 on chromatin at 1W and 8W, when PFA occurs and follicles initiate the transition toward growing follicles, but not at E14, and that were associated with any of the following terms in OMIM database: “premature ovarian failure,” “hypogonadisms,” or “infertility,” to enrich for factors more likely to be relevant to human conditions.
