Web5 de jun. de 2012 · During oogenesis, the oocyte undergoes dynamic alterations in gene expression which are regulated by a set of well-coordinated transcription factors active in the germ line and soma. A number of germ cell specific as well as somatic expressed transcriptional regulators are critical in ovarian formation and folliculogenesis. Web11 de abr. de 2024 · The regulation of oocytes in primordial follicles has been well-studied in mice. A critical regulator of dormancy is FOXO3. FOXO3-deficient mice showed activation of all oocytes soon after birth, resulting in primary ovarian insufficiency (POI) (Castrillon et al., 2003).FOXO3 is regulated by its translocation from the nucleus to the cytoplasm, which … dating apps south carolina
