Description:
The most common inherited [correct] form of amyotrophic lateral sclerosis (ALS), a neurodegenerative disease affecting adult motor neurons, is caused by dominant mutations in the ubiquitously expressed Cu-Zn superoxide dismutase (SOD1). In chimeric mice that are mixtures of normal and SOD1 mutant-expressing cells, toxicity to motor neurons is shown to require damage from mutant SOD1 acting within nonneuronal cells. Normal motor neurons in SOD1 mutant chimeras develop aspects of ALS pathology. Most important, nonneuronal cells that do not express mutant SOD1 delay degeneration and significantly extend survival of mutant-expressing motor neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clement, A M -- Nguyen, M D -- Roberts, E A -- Garcia, M L -- Boillee, S -- Rule, M -- McMahon, A P -- Doucette, W -- Siwek, D -- Ferrante, R J -- Brown, R H Jr -- Julien, J-P -- Goldstein, L S B -- Cleveland, D W -- AG 12992/AG/NIA NIH HHS/ -- AG 13846/AG/NIA NIH HHS/ -- HD 30249/HD/NICHD NIH HHS/ -- NS 27036/NS/NINDS NIH HHS/ -- NS 31248/NS/NINDS NIH HHS/ -- NS 37912/NS/NINDS NIH HHS/ -- R37 NS027036/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):113-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, University of California, 9500 Gilman Drive, La Jolla, CA 92093-0670, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526083" target="_blank"〉PubMed〈/a〉
