ABSTRACT
Objective To investigate the expression of miR-155 ,nuclear factor kappa B (NF-κB) and soluble intercellular adhesion molecule -1 (sICAM-1 ) in peripheral blood in patients with type 2 diabetes mellitus (T2DM ) ,and to explore the role of miR-155 in vascular lesions of T2DM. Methods A total of 165 T2DM patients and 60 health subjects from health examinations were enrolled in this study. All the subjects were divided into two groupssubjects without vascular lesions group and vascular disease group. Vascular disease group was further divided into microangiopathy group ,macroangiopathy group , microangiopathy+ macroangiopathy group ;based on 24 hUAlb level normal urinary albumin (NAU ) group ,microalbuminuria (MAU) group ,macroalbuminuria (MAAU) group. MiR-155 ,NF-κB and sICAM-1 in peripheral blood were tested by RT-PCR. Single factor analysis of variance was used for comparison among groups. Stepwise regression analysis was used for correlation factors analysis. Results The expression of miR-155 ,NF-κB and sICAM-1 were significantly higher in T2DM group than in NC group [(1.82 ± 0.71) vs (1.00 ± 0.12) ,(2.28 ± 0.66) vs (1.04 ± 0.33) ,(1.88 ± 0.80) vs (1.03 ± 0.30) ,P<0.05]. The level of miR-155 ,NF-κB ,sICAM-1 were significantly higher in T2DM vascular lesions group than in subjects without vascular lesions group [(1.95 ± 0.73) vs (1.34 ± 0.29) ,(2.40 ± 0.65) vs (1.65 ± 0.16 ) ,(2.01 ± 0.77 ) vs (1.07 ± 0.41 ) ,P < 0.05 ]. The expression of miR-155 was higher in microangiopathy+ macroangiopathy group than in macroangiopathy group [(2.36 ± 0.61 ) vs (1.77 ± 0.59) ,P < 0.05 ].The expression of NF-κB was also significantly higher in microangiopathy +macroangiopathy group than in microvascular disease group and macroangiopathy group (P<0.05). The level of miR-155 was significantly higher in group MAU group and MAAU group than in NAU group [(1.41 ± 0.49) ,(2.64 ± 0.52) vs (1.04 ± 0.20) ,P<0.05] ,and NF-κB and sICAM-1 were also higher than NAU group (P<0.05). Multiple stepwise regression analysis showed that miR-155 was positively correlated with NF-κB and sICAM-1(t=4.235 ,9.728 ,P<0.01). Conclusion The expression of miR-155 increases in T2DM patients with vascular complications ,and this trend is the same as NF-κB and sICAM-1. It suggests that miR-155 maybe involves in the pathogenesis of diabetic chronic vascular disease.
