ABSTRACT
Objective:
To explore expression of miR-146b in peripheral blood serum and aortic wall tissues in patients with acute Stanford type A aortic dissection (TAAD),and to discuss the significance and underlying mechanisms.Methods:
The subjects were divided into a control group (excluded relative aortic diseases) (n=23) and a TAAD group (n=27).The miR-146b levels of serum and aortic wall tissues were detected by quantitative real-time PCR (qRT-PCR).Serum miR-146b and aortic wall tissues miR-146b were compared among different risk TAAD groups.The correlations between miR-146b and severity of aortic dissection were analyzed.MiR-146b related target genes were predicted by the DIANA LAB-TarBase 6.0 and TargetScan.Results:
The expression levels of miR-146b in the serum and aortic wall tissues in the TAAD group were significantly elevated compared with those in the control group (P<0.001).Compared with the mild risk group,the miR-146b levels of serum and aortic wall tissues were significantly higher in the moderate risk and severe risk groups (P<0.05).The expression of miR-146b was positively correlated with the risk severity of TAAD patients (r=0.862,0.872;P<0.05).Nuclear factor kappa B1 (NF-κB1),tumor necrosis factor receptor-associated factor 6 (TRAF6),matrix metalloproteinase 16 (MMP16) and actin alpha 2 (ACTA2) were miR-146b related target genes.Conclusion:
The upregulation of miR-146b in peripheral blood serum and aortic wall tissues may contribute to the pathogenesis of TAAD and the severity of this disease.
