Correlation between miR-103 and miR-133a Expression and the Circulating ANGPTL8 in Type 2 Diabetic Patients and
Background:
Angiopoietin-like protein 8 (ANGPTL8) is a circulatory hormone that plays an important role in the proliferation of the pancreatic beta cells and lipid metabolism. MicroRNAs (miRs) are small non-coding RNAs that play an important role in the pathogenesis of diabetes mellitus. Therefore, we investigated the correlation of miR-103 and miR-133a expression with the ANGPTL8 and other type 2 diabetes mellitus (T2DM)-related factors.
Methods:
Seventy subjects (controls: n = 35 and type 2 diabetic patients: n = 35) participated in this study. The ANGPTL8 concentration and miR-103/133a expression were measured using ELISA and real-time PCR, respectively.
Results:
The circulatory ANGPTL8 concentration and miR-103/133a expression was significantly higher in T2D patients than in healthy controls (p < 0.05). There was a positive and significant correlation between miR-103/133a with triglycerides (TG), total cholesterol, fasting blood sugar (FBS), and glycated hemoglobin (p < 0.05) in the T2D group. The results also showed a negative and significant correlation between miR-103/133a expression with ANGPTL8 levels in the T2D group (p < 0.05).
Conclusions:
Our results suggest that miR-103/133a expression is correlated with the ANGPTL8 and T2D-related factors.
