ARTICLE HIGHLIGHTS
Research background

Sensitive, novel, and accurate biomarkers for the detection of physiological changes in type 2 diabetes (T2DM) at an early stage are urgently needed. MicroRNAs (miRNAs) are found not only in the cell but also outside the cell, including body fluids, such as serum, saliva, and nasal secretions. Extracellular miRNAs were demonstrated to be stable in serum or plasma due to their presence as protein complexes. Abnormal expression of miRNAs is related to the occurrence and development of many diseases, such as cancer and T2DM.

Research motivation

MiRNAs in the serum or plasma are stable, can be reproducibly detected, and therefore have the potential as novel biomarkers for a variety of diseases, include T2DM.

Research objectives

This study aimed to build a multi-parameter diagnostic model for the early detection of T2DM.

Research methods

MiR-148b, miR-223, miR-130a, and miR-19a levels were detected in serum of healthy controls, individuals with impaired glucose regulation, and T2DM patients. The detection value of these miRNAs, alone and in combination, was analyzed.

Research results

The area under the curve of miR-223, which had the best diagnostic value for discriminating the impaired glucose regulation and T2DM groups, was 0.84, and the sensitivity and specificity were 73.37% and 81.37%, respectively. The area under curve of the four-miRNA signature was 0.90, and the sensitivity and specificity were 78.82% and 88.23%, respectively.

Research conclusions

In this study, the authors built a multi-parameter diagnostic model containing miR-148b, miR-223, miR-130a, and miR-19a for the detection of T2DM. It may be a potential tool for the early detection of T2DM.

Research perspectives

The specific mechanism by which the miRNAs are involved in T2DM can be explored in the future.
