Serum levels miR-391-3p and miR-221-3p as potential biomarkers for diagnosis of diabetes

Abstract

Objectives: Type 2 diabetes (T2D) is a chronic metabolic disorder characterized by insulin resistance and progressive β-cell dysfunction. Early detection is extremely important for effective management and the prevention of complications. Circulating microRNAs (miRNAs) been found to be promising non-invasive biomarkers for a variety of diseases, including metabolic disorders. The purpose of this study was to assess the diagnostic potential of serum microRNA-29a-3p (miR-29a-3p) and microRNA-221-3p (miR-221-3p) in patients with T2D.

Methods: A case-control study was conducted involving 48 T2D patients and 42 healthy controls. Serum levels of miR-29a-3p and miR-221-3p were quantified using real-time PCR.

Results: Both miR-29a-3p and miR-221-3p were significantly increased in sera of T2D patients compared to controls. Serum miR-29a-3p and miR-221-3p were positively correlated with fasting blood glucose (r = 0.466), (r = 0.403) and HbA1c (r = 0.375), (r = 0.366), respectively. miR-29a-3p showed moderate correlations with TG (r = 0.300) after adjustment for BMI, age and gender. Both miRNAs also correlated with adiposity parameters such as body mass index, weight and waist circumference.

Conclusion: Serum miR-29a-3p and miR-221-3p are significantly upregulated in T2D and correlate with key metabolic markers. Their diagnostic performance suggests that they can function as valuable non-invasive biomarkers for the early detection and monitoring of T2D. Further research is needed to examine these results in larger and more diverse population groups.
