"Data suggest that sortilin expression in both gastrocnemius and extensor digitorum longus muscle is down-regulated by 17-18h of fasting/food deprivation; pathological levels of high blood glucose as in streptozotocin-induced diabetes do not alter sortilin expression in skeletal muscle; sortilin expression is elevated during differentiation of myocyte cell line or in presence of high concentration of glucose."xsd:string
