Clinical research on the mechanism of miRNA-126 and miRNA-28-3p in diabetes mellitus patients / 局解手术学杂志

ABSTRACT

Objective To explore the mechanism of plasma circulating miRNA-126 and miRNA-28-3p in diabetes mellitus (DM) patients,and to identify the related bioinformatics analysis.Methods Randomly selected 80 DM patients as the observation group and 80 non-DM patients as the control group.The plasma circulating miRNA-126 and miRNA-28-3p were analyzed by qRT-PCR,and its target genes,biological information,related lncRNA and circRNA were predicted.Results The circulating miRNA-126(0.115 0±0.014 4 vs.0.0019±0.000 6) and miRNA-28-3p(0.1386±0.01724 vs.0.000 6±0.000 05) levels in the observation group were significantly higher than those in the control group,and the differences were statistically significant (P<0.01).Pearson correlation coefficient of miRNA-126 and miRNA-28-3p was 0.433 5(P<0.01).ROC curve analysis of miRNA-126 and miRNA-28-3p showed that the differences of the area under curve were statistically significant between the two groups (P<0.01).Bioinformatics prediction showed that miRNA-126 and miRNA-28-3p may be involved in regulation of the insulin signaling pathway,insulin receptor signaling pathway,insulin/insulin growth factor signaling pathway,mitogen-activated protein kinase (MAPK) signaling pathway and angiogenesis.And it may be associated with a variety of lncRNA and circRNA.Conclusion Circulating miRNA-126 and miRNA-28-3p can be a novel biomarker of DM as it may participate in the mechanism of DM by regulating insulin and insulin growth factor related signaling pathways and be associated with some related lncRNA and circRNA.
