Our data indicates that upregulation of the Orai1-mediated SOCE pathway and an overloaded SR Ca2+ store contributes to the disrupted Ca2+ homeostasis in mdx muscles and is linked to elevated proteolytic activity, suggesting that targeting Orai1 activity may be a promising therapeutic approach for the prevention and treatment of muscular dystrophy. This evidence concerns the gene ORAI1 and muscular dystrophy.
