Disruption of this equilibrium results in a myriad of structural abnormalities and disorders of the nervous system. The molecular mechanism that restricts neural progenitor expansion is poorly understood. Here we show that the tumor suppressor neurofibromatosis 2 (Nf2; merlin) limits the expansion of neural progenitor cells (NPCs) in the mammalian dorsal telencephalon. Nf2 is localized at the apical region of NPCs. In the absence of Nf2, NPCs of the cortical hem, hippocampal primordium and neocortical primordium overexpand, while production of Cajal-Retzius cells and hippocampal neurons decreases, resulting in severe malformation of the hippocampus in adult mice. We further show that Nf2 functions by inhibiting the Yap\/Taz transcriptional coactivators, probably through a mechanism that is distinct from the canonical Hippo pathway. Overexpressing human YAP in NPCs causes a hippocampal malformation phenotype that closely resembles that of Nf2 mutants and, importantly, deleting Yap in the Nf2 mutant background largely restores hippocampal development. Our studies uncover Nf2 as an important inhibitor of neural progenitor expansion and establish Yap\/Taz as key downstream effectors of Nf2 during brain development.<\/jats:p>","DOI":"10.1242\/dev.096537","type":"journal-article","created":{"date-parts":[[2013,7,18]],"date-time":"2013-07-18T01:47:53Z","timestamp":1374112073000},"page":"3323-3334","source":"Crossref","is-referenced-by-count":106,"title":["Tumor suppressor Nf2 limits expansion of the neural progenitor pool by inhibiting Yap\/Taz transcriptional coactivators"],"prefix":"10.1242","volume":"140","author":[{"given":"Alfonso","family":"Lavado","sequence":"first","affiliation":[{"name":"Department of Developmental Neurobiology, St Jude Children\u2019s Research Hospital, Memphis, TN 38105, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"He","sequence":"additional","affiliation":[{"name":"Department of Developmental Neurobiology, St Jude Children\u2019s Research Hospital, Memphis, TN 38105, USA."},{"name":"Integrated Biomedical Science Program, University of Tennessee Health Science Center, Memphis, TN 38105, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua","family":"Par\u00e9","sequence":"additional","affiliation":[{"name":"Department of Developmental Neurobiology, St Jude Children\u2019s Research Hospital, Memphis, TN 38105, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey","family":"Neale","sequence":"additional","affiliation":[{"name":"Hartwell Center for Bioinformatics and Biotechnology, St Jude Children\u2019s Research Hospital, Memphis, TN 38105, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric N.","family":"Olson","sequence":"additional","affiliation":[{"name":"Department of Molecular Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390-9148, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Giovannini","sequence":"additional","affiliation":[{"name":"House Research Institute, University of Southern California, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinwei","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Developmental Neurobiology, St Jude Children\u2019s Research Hospital, Memphis, TN 38105, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042622103084900_R1","doi-asserted-by":"crossref","first-page":"2771","DOI":"10.1002\/dvdy.20883","article-title":"Regulation of the neurofibromatosis 2 gene promoter expression during embryonic development","volume":"235","author":"Akhmametyeva","year":"2006","journal-title":"Dev.
