No therapies are currently available for nGD since the recombinant enzymes used in the systemic form of Gaucher disease do not cross the blood\u2013brain barrier (BBB). However, a number of promising approaches are currently being tested, including substrate reduction therapy (SRT), in which partial inhibition of the synthesis of the glycosphingolipids (GSLs) that accumulate in nGD lowers their accumulation. We now induce nGD in mice by injection with conduritol B\u2010epoxide (CBE), an irreversible inhibitor of acid beta\u2010glucosidase (GCase), the enzyme defective in nGD, with or without co\u2010injection with Genz\u2010667161, a prototype for SRT which crosses the BBB. Significant neuropathology, and a reduction in lifespan, was observed upon CBE injection, and this was largely reversed by co\u2010injection with Genz\u2010667161, along with a reduction in glucosylceramide and glucosylsphingosine levels. Analysis of gene expression by RNAseq revealed that Genz\u2010667161 largely reversed the changes in genes and pathways that were differentially expressed upon CBE injection, specifically pathways of GSL metabolism, lipoproteins and other lipid metabolic pathways, lipid droplets, astrocyte activation, neuronal function, and to some extent, neuroinflammation. Together, this demonstrates the efficacy of SRT to reverse the effects of substrate accumulation on pathological components and pathways in nGD brain.<\/jats:p><\/jats:sec><jats:sec><jats:label\/><jats:p>\n<jats:boxed-text content-type=\"graphic\" position=\"anchor\"><jats:graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" mimetype=\"image\/png\" position=\"anchor\" specific-use=\"enlarged-web-image\" xlink:href=\"graphic\/jnc15136-fig-0004-m.png\"><jats:alt-text>image<\/jats:alt-text><\/jats:graphic><\/jats:boxed-text>\n<\/jats:p><\/jats:sec>","DOI":"10.1111\/jnc.15136","type":"journal-article","created":{"date-parts":[[2020,8,3]],"date-time":"2020-08-03T08:51:13Z","timestamp":1596444673000},"page":"692-701","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Substrate reduction therapy using Genz\u2010667161 reduces levels of pathogenic components in a mouse model of neuronopathic forms of Gaucher disease"],"prefix":"10.1111","volume":"156","author":[{"given":"Shani","family":"Blumenreich","sequence":"first","affiliation":[{"name":"Department of Biomolecular Sciences Weizmann Institute of Science Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Yaacobi","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences Weizmann Institute of Science Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayelet","family":"Vardi","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences Weizmann Institute of Science Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Or B.","family":"Barav","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences Weizmann Institute of Science Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Einat B.","family":"Vitner","sequence":"additional","affiliation":[{"name":"Departments of Infectious Diseases Israel Institute for Biological Research Ness\u2010Ziona Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyejung","family":"Park","sequence":"additional","affiliation":[{"name":"Analytical Research and Development Sanofi, Waltham MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Wang","sequence":"additional","affiliation":[{"name":"Analytical Research and Development Sanofi, Waltham MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seng H.","family":"Cheng","sequence":"additional","affiliation":[{"name":"Rare and Neurologic Diseases Research Therapeutic Area Sanofi, Framingham MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio P.","family":"Sardi","sequence":"additional","affiliation":[{"name":"Rare and Neurologic Diseases Research Therapeutic Area Sanofi, Framingham MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0013-0115","authenticated-orcid":false,"given":"Anthony H.","family":"Futerman","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences Weizmann Institute of Science Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,9,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btu638"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0896-6273(00)80166-X"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1089\/omi.2015.0168"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.R000005200"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0043310"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1800165115"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(00)02161-9"},{"key":"e_1_2_8_9_1","doi-asserted-by":"crossref","unstructured":"Futerman A.
