Initially identified in the northern Quebec region of Charlevoix-Sagenay, but now diagnosed around the world, ARSACS is caused by loss-of-function mutations in the <em data-start=\"776\" data-end=\"782\">SACS<\/em> gene. Its gene product, Sascin, is a gigantic multi-domain protein thought to help properly assemble equally large protein complexes. Unlike many models of human diseases, the <em data-start=\"959\" data-end=\"965\">Sacs<\/em> KO mouse is a faithful model of ARSACS, displaying ataxia, muscle weakness, PC loss, and even dementia as we have recently reported (PMID: 38735882). A better understanding of pathogenic mechanisms in the <em data-start=\"1171\" data-end=\"1177\">Sacs<\/em> KO mouse likely has therapeutic implications not only for ARSACS, but for cerebellar disorders in general.<\/p>\n<p data-start=\"1289\" data-end=\"1615\">We have generated a large capacity adenoviral vector to express full-length Sacsin in the brain of Sacs KO mice as poof-of-concept for gene therapy. In parallel, we have made a conditional knock-out (cKO) model of ARSACS in order to identify cell types and brain regions responsible for motor and cognitive deficits in ARSACS.<\/p>\n<p>Subvention : $100 000<br \/>\n<strong>This is a jointly founded project with Action for ARSACS Foundation USA (AFA)<\/strong><br \/>\nDur\u00e9e : un an<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-26215 alignleft\" src=\"https:\/\/arsacs.com\/wp-content\/uploads\/2026\/04\/Stefan-Strack_2026-03-11-249x300.jpg\" alt=\"\" width=\"249\" height=\"300\" \/><strong data-start=\"907\" data-end=\"927\">Dr Stefan Strack<\/strong><br data-start=\"927\" data-end=\"930\" \/>Professor and Vice Chair<br data-start=\"954\" data-end=\"957\" \/>Department of Neuroscience and Pharmacology<br data-start=\"1000\" data-end=\"1003\" \/>Facult\u00e9 de m\u00e9decine Carver de l'Universit\u00e9 de l'Iowa<br data-start=\"1048\" data-end=\"1051\" \/>2-452 Bowen Science Building<br data-start=\"1079\" data-end=\"1082\" \/>51 Newton Road<br data-start=\"1096\" data-end=\"1099\" \/>Iowa City, IA 52242, USA<br data-start=\"443\" data-end=\"446\" \/>Contact : <a class=\"decorated-link cursor-pointer\" rel=\"noopener\" data-start=\"457\" data-end=\"480\">stefan-strack@uiowa.edu<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>This project focuses on developing conditional mouse models and new approaches to treating ARSACS.<\/p>","protected":false},"author":9,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[105],"tags":[],"class_list":["post-26941","post","type-post","status-publish","format-standard","hentry","category-research-in-2025"],"_links":{"self":[{"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/posts\/26941","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/comments?post=26941"}],"version-history":[{"count":7,"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/posts\/26941\/revisions"}],"predecessor-version":[{"id":26986,"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/posts\/26941\/revisions\/26986"}],"wp:attachment":[{"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/media?parent=26941"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/categories?post=26941"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/arsacs.com\/fr\/wp-json\/wp\/v2\/tags?post=26941"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
