Background:
miRNA-181a has been implicated in autoimmunity and apoptosis. Therefore, this study was conducted to explore its possible role in pancreatic beta-cells dysfunction.
Methods:
miRNA-181a expression was evaluated by real-time PCR in serum of 40 type 1 diabetic children and adolescents and 40 age- and gender-matched healthy controls.
Results:
miRNA-181a expression was significantly higher in diabetic children and adolescents and it was negatively correlated to fasting C-peptide and SMAD7 levels.
Conclusion:
miRNA-181a appears to play a potential role in pancreatic beta-cells dysfunction via SMAD7.
