Abstract
Background & aims: This study investigated a possible correlation between three circulating miRNAs, previously observed to be associated to diabetic polyneuropathy, and the obesity condition. Methods & results: The expression levels of miR-128a, miR-155 and miR499a were evaluated in 49 participants with Type 2 diabetes, divided into different groups based on the presence or absence of obesity and central obesity. The analyses revealed a significant decrease of miR-155 and miR-499a expression levels in obese subjects. In particular, the reduction appears to be even more significant in Type 2 diabetes subjects with central obesity. Conclusion: The results suggest that these miRNAs could be involved in obesity-driven pathogenetic mechanisms.
