  • Title: Lessons from models of SOD1-linked familial ALS.
    Author: Bendotti C, Carrì MT.
    Journal: Trends Mol Med; 2004 Aug; 10(8):393-400. PubMed ID: 15310460.
    Abstract:
    Ten years ago, the linkage between mutations in the gene coding for the antioxidant enzyme Cu,Zn superoxide dismutase (SOD1) and the neurodegenerative disease known as familial amyotrophic lateral sclerosis (FALS) was established. This finding has prompted a myriad of new studies in experimental models aimed at investigating the toxic function of the mutant enzymes. The cellular functions that are impaired in motoneurons as a consequence of molecular alterations induced by the expression of FALS SOD1 converge on pathways that might be activated in sporadic ALS by other toxic factors. Recent data demonstrate that, although motoneurons are lost in patients, other cell types are also affected and actively contribute to the pathogenesis of the disease.
