Elevated Levels of Circulating miR-92a Are Associated with Impaired Glucose Homeostasis in Patients with Obesity and Correlate with Metabolic Status After Bariatric Surgery

miRNAs are small non-coding RNAs, some of which are expressed in adipose tissues, are present in the circulation, and are regulated in obesity. Bariatric surgery (BS) has been proposed to lead to activation of brown adipose tissue, an effect that may be related to beneficial effects of BS on systemic metabolism. Here, we evaluated circulating levels of miR-92a and miR-99b, two miRNAs proposed as biomarkers of brown fat activity, in a cohort of...
