Abstract:
Objective To determine the serum levels of miR-16,miR-126 and miR-221 in type 2 diabetes (T2DM)patients with or without microvascular complications,and further evaluate their clinical significance.Methods The serum levels of miR-16,miR-126 and miR-221were examined in 55 T2DM patients,55 T2DM patients with microvascular complications and 5 5 healthy controls using quantitative real-time PCR (qRT-PCR).The levels of fasting blood glucose,triglycerides,choles-terol,high density lipoprotein,low density lipoprotein and others biochemical parameters were determined by biochemical an-alyzer,and the diagnostic usefulness of the three miRNAs for T2DM patients and patients with microvascular complications were assessed by ROC curve analysis and logistic regression analysis.Results Compared with healthy controls [miR-1 6 (14.35±1.00)×10-5 ,miR-126(11.75±1.47)×10-5 and miR-221(32.26±3.98)×10-5 ],the miR-16,miR-126 and miR-221 expression were significantly increased in T2DM patients [miR-16(23.74±2.70)×10-5,miR-126(25.01±4.13)× 10-5 and miR-221(84.76±11.79)×10-5 ]and T2DM patients with microvascular complications [miR-16(43.74±9.61)× 10-5 ,miR-126(17.66±2.20)×10-5 and miR-221(82.52±12.48)×10-5 ].The area under ROC curve (AUCROC)of miR-16,miR-126 and miR-221 for T2DM patients were 0.63 (95%CI 0.53~0.74),0.64 (95%CI 0.54~0.74)and 0.74 (95%CI 0.65~0.83),respectively.For T2DM patients with microvascular complications,the area under ROC curve were 0.75 (95%CI 0.66~0.84),0.62 (95%CI 0.52~0.73)and 0.73 (95%CI 0.64~0.83),respectively.Furthermore,logistic re-gression revealed that the three miRNAs were novel independent risk factors for T2DM and T2DMC.Conclusion The levels of miR-16,miR-126 and miR-221 were significantly increased in the serum of T2DM patients with or without microvascular complications,and can be used as potential non-invasive biomarkers and risk factors for T2DM patients and T2DM patients with microvascular complications.
