Abstract:
Diabetes is a severe condition worldwide. It is characterized by chronic hyperglycemia and is caused by defects in insulin production, secretion, and action. Both genetic and environmental factors contribute to the development of type 1 and type 2 diabetes. The pathogenesis of diabetes is complex and the underlying molecular mechanisms are only partially understood. MicroRNAs (miRNAs) play a fundamental role in diabetes and its complications. This chapter focuses on the dysregulation of miRNAs involved in the regulation of pancreatic islet insulin production and secretion as well as action and signaling in peripheral tissues. The roles of miRNAs in the development of diabetic complications are also discussed. Modulating miRNA expression, by either upregulation or inhibition, holds a promise as a strategy for treating this metabolic disease.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
