We report here that a familial mouse model (transgenic mice over-expressing the G93A mutation of the Cu\/Zn superoxide dismutase 1 gene) of ALS enters a progressive state of acidosis that is associated with several metabolic (hormonal) alternations that favor lipolysis. Extensive investigation of the major determinants of H\n                    <jats:sup>+<\/jats:sup>\n                    concentration (i.e., the strong ion difference and the strong ion gap) suggests that acidosis is also due in part to the presence of an unknown anion. Consistent with a compensatory response to avert pathological acidosis, ALS mice harbor increased accumulation of glycogen in CNS and visceral tissues. The altered glycogen is associated with fluctuations in lysosomal and neutral \u03b1-glucosidase activities. Disease-related changes in glycogen, glucose, and \u03b1-glucosidase activity are also found in spinal cord tissue samples of autopsied patients with ALS. Collectively, these data provide insights into the pathogenesis of ALS as well as potential targets for drug development.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1308421110","type":"journal-article","created":{"date-parts":[[2013,6,11]],"date-time":"2013-06-11T00:02:47Z","timestamp":1370908967000},"page":"10812-10817","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":124,"title":["Metabolic signatures of amyotrophic lateral sclerosis reveal insights into disease pathogenesis"],"prefix":"10.1073","volume":"110","author":[{"given":"James C.","family":"Dodge","sequence":"first","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher M.","family":"Treleaven","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan A.","family":"Fidler","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas J.","family":"Tamsett","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Channa","family":"Bao","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Searles","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatyana V.","family":"Taksir","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuma","family":"Misra","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard L.","family":"Sidman","sequence":"additional","affiliation":[{"name":"Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02215"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seng H.","family":"Cheng","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lamya S.","family":"Shihabuddin","sequence":"additional","affiliation":[{"name":"Genzyme, a Sanofi Company, Framingham, MA 01701-9322; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2013,6,10]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/364362c0"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.8209258"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.neuro.27.070203.144244"},{"key":"e_1_3_3_4_2","doi-asserted-by":"crossref","unstructured":"YD Teng et al.
