چکیده    Micrornas (mirnas) are noncoding rnas of ~22 nucleotides that regulate gene expression post-transcriptionally by binding to the 3′ untranslated region of messenger rna (mrnas), resulting in inhibition of translation or mrna degradation. mirnas have a key role in fine-tuning cellular functions such as proliferation, differentiation and apoptosis, and they are involved in carcinogenesis, glucose homeostasis, inflammation and other biological processes. in this review, we focus on the role of mirnas in the pathophysiology of the metabolic disease and diabetes mellitus, the hallmark of which is hyperglycemia caused by defective insulin secretion and/or action. a growing number of studies have revealed the association between mirnas and the processes of insulin production and secretion in pancreatic β cells. in addition, aberrant expression of mirnas in skeletal muscle, adipose tissue and liver has also been reported. intriguingly, the tumor suppressor p53 has been implicated in the pathogenesis of diabetes in association with a number of mirnas, suggesting that a p53/mirna pathway might be a therapeutic target. moreover, data from genome-wide association studies have revealed that several mirna target sequences overlap type 2 diabetes susceptibility loci. finally, the recent discovery of circulating mirnas associated with diabetes onset/progression suggests the potential use of mirnas as biomarkers.
