Skeletal muscle atrophy in various species has been related to CCN1/CYR61 upregulation: CCN1/CYR61 mRNA, protein, or both, are increased in atrophic mouse models of type-I diabetes [59], atrophy due to malnutrition in bovines [60], muscle waste in patients with chronic obstructive pulmonary disease (COPD) [61], atrophic muscle in mouse model of Amyotrophic lateral sclerosis (ALS) [62], and aging-related sarcopenia in mice and rats [44]. This evidence concerns the gene CCN1 and amyotrophic lateral sclerosis.
