An Overview of Differential miRNA Profile of Patients with Latent Autoimmune Diabetes in Adults (LADA)

Abstract

Diabetes mellitus (DM) is a metabolic and chronic disease characterized by hyperglycemia developing with impaired pancreatic beta cell activity, decreased insulin secretion, icreased insulin resistance, and accordingly impaired carbohydrate, protein and lipid metabolism. DM is classified as type 1, type 2, gestational and other forms of diabetes according to the characteristic properties such as age of onset, insulin dependency, micro- and macrovascular complications. Latent autoimmune diabetes in adults (LADA) is an autoimmune diabetes that begins in adulthood without insulin dependency for glycemic control at least in the first six months after diagnosis. Owing to the common genetic, immunologic, and metabolic features LADA is misdiagnosed with type 1 or type 2 diabetes. Therefore, it is need a biomarkers that ease the diagnosis of LADA. MicroRNAs are small non-coding RNAs involved in biological processes and regulate the response of target tissues to insulin as well as insulin production, signaling and release, insulin resistance, and glucose homeostasis. Dysregulation in miRNA expression can lead to impairment of glucose metabolism. Circulating miRNA are associated with different types of diabetes and have a potential to discriminate them. So, we reviewed the miRNAs that gene expressions levels which change in LADA compared to type 1 and type 2 diabetes.
