We have investigated the role of the alternative-splicing factor Sfrs1, an arginine\/serine-rich (SR)protein family member, during mouse retinal development. Loss of Sfrs1 function during embryonic retinal development had a profound effect, leading to a small retina at birth. In addition, the retina underwent further degeneration in the postnatal period. Loss of Sfrs1 function resulted in the death of retinal neurons that were born during early to mid-embryonic development. Ganglion cells, cone photoreceptors, horizontal cells and amacrine cells were produced and initiated differentiation. However,these neurons subsequently underwent cell death through apoptosis. By contrast, Sfrs1 was not required for the survival of the neurons generated later, including later-born amacrine cells, rod photoreceptors,bipolar cells and Mu\u0308ller glia. Our results highlight the requirement of Sfrs1-mediated alternative splicing for the survival of retinal neurons, with sensitivity defined by the window of time in which the neuron was generated.<\/jats:p>","DOI":"10.1242\/dev.024620","type":"journal-article","created":{"date-parts":[[2008,11,5]],"date-time":"2008-11-05T20:24:50Z","timestamp":1225916690000},"page":"3923-3933","source":"Crossref","is-referenced-by-count":16,"title":["Temporal requirement of the alternative-splicing factor\n                    <i>Sfrs1<\/i>\n                    for the survival of retinal neurons"],"prefix":"10.1242","volume":"135","author":[{"given":"Rahul N.","family":"Kanadia","sequence":"first","affiliation":[{"name":"Department of Genetics, Harvard Medical School, Boston, MA 02115, USA."},{"name":"Howard Hughes Medical Institute, Chevy Chase, MD 20815, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria E.","family":"Clark","sequence":"additional","affiliation":[{"name":"Department of Genetics, Harvard Medical School, Boston, MA 02115, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Punzo","sequence":"additional","affiliation":[{"name":"Department of Genetics, Harvard Medical School, Boston, MA 02115, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey M.","family":"Trimarchi","sequence":"additional","affiliation":[{"name":"Department of Genetics, Harvard Medical School, Boston, MA 02115, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Constance L.","family":"Cepko","sequence":"additional","affiliation":[{"name":"Department of Genetics, Harvard Medical School, Boston, MA 02115, USA."},{"name":"Howard Hughes Medical Institute, Chevy Chase, MD 20815, USA."},{"name":"Department of Ophthalmology, Harvard Medical School, Boston, MA 02115,USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042621164799600_REF1","doi-asserted-by":"crossref","unstructured":"Caceres, J.
