It is currently suggested that GLP-1 analogues could be helpful in the management of type 1 diabetes, not only because can contribute to improve the metabolic control and to reduce insulin requirement [14], but also because GLP-1 can protect type 1 diabetes from hyperglycemia and hypoglycemia-induced oxidative stress, inflammation and endothelial dysfunction [34]. The gene discussed is INS; the disease is endothelial dysfunction.
