Individuals affected by FOXG1 syndrome frequently exhibit delayed myelination in neuroimaging studies, which may impair the rapid conduction of nerve impulses. To date, the specific effects of FOXG1 on oligodendrocyte lineage progression and myelination during early postnatal development remain unclear. Here, we investigated the effects of Foxg1 deficiency on myelin development in the mouse brain by conditional deletion of Foxg1 in neural progenitors using NestinCreER;Foxg1fl\/fl mice and tamoxifen induction at postnatal day 0 (P0). We found that Foxg1 deficiency resulted in a transient delay in myelination, evidenced by decreased myelin formation within the first two weeks after birth, but ultimately recovered to the control levels by P30. We also found that Foxg1 deletion prevented the timely attenuation of platelet-derived growth factor receptor alpha (PDGFR\u03b1) signaling and reduced the cell cycle exit of oligodendrocyte precursor cells (OPCs), leading to their excessive proliferation and delayed maturation. Additionally, Foxg1 deletion increased the expression of Hes5, a myelin formation inhibitor, as well as Olig2 and Sox10, two promoters of OPC differentiation. Our results reveal the important role of Foxg1 in myelin development and provide new clues for further exploring the pathological mechanisms of FOXG1 syndrome.<\/jats:p>","DOI":"10.3390\/ijms241813921","type":"journal-article","created":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T09:00:52Z","timestamp":1694422852000},"page":"13921","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Conditional Deletion of Foxg1 Delayed Myelination during Early Postnatal Brain Development"],"prefix":"10.3390","volume":"24","author":[{"given":"Guangliang","family":"Cao","sequence":"first","affiliation":[{"name":"Department of Human Anatomy, School of Medicine, Southeast University, Nanjing 210009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Congli","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Physiology, School of Medicine, Southeast University, Nanjing 210009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hualin","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Human Anatomy, School of Medicine, Southeast University, Nanjing 210009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dewei","family":"Qu","sequence":"additional","affiliation":[{"name":"Department of Human Anatomy, School of Medicine, Southeast University, Nanjing 210009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuanlu","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology, School of Medicine, Southeast University, Nanjing 210009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiqin","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Human Anatomy, School of Medicine, Southeast University, Nanjing 210009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1007\/s00401-009-0601-5","article-title":"Oligodendrocytes: Biology and Pathology","volume":"119","author":"Bradl","year":"2010","journal-title":"Acta Neuropathol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1016\/bs.mcb.2015.12.004","article-title":"Oligodendrocyte Differentiation","volume":"134","author":"Mathews","year":"2016","journal-title":"Methods Cell Biol."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"779125","DOI":"10.3389\/fnins.2021.779125","article-title":"Neuron to Oligodendrocyte Precursor Cell Synapses: Protagonists in Oligodendrocyte Development and Myelination, and Targets for Therapeutics","volume":"15","author":"Moura","year":"2022","journal-title":"Front.
