Evaluation of microRNA-29a expression and Dipeptidyl-peptidase 4 level in ulcerative colitis patients

Abstract

Objective: Ulcerative colitis (UC) is a recurrent inflammatory bowel disease (IBD) that increases at an alarming rate around the world. The microRNA-29 (miRNA-29) family has been implicated in the pathogenesis of UC. In recent year, the alteration of Dipeptidyl-peptidase 4 (DPP4) levels in IBD patients has been reported. In the present study, we evaluated the relationship between miRNA-29a expression of intestinal tissue and serum DPP4 level in UC patients and healthy subjects.

Methods: Blood samples and colonic punch biopsy were obtained from 35 UC, and 29 healthy subjects. Serum levels of DPP-4 were evaluated by ELISA technique. The expression levels of miRNA-29 were assessed by qRT-PCR. Also, biochemical parameters and demographic information were collected based on patient tests and questionnaire.

Results: The results of this study showed a significant increase of miRNA-29a in intestinal tissue of UC patients compared to control. In addition, elevated expression of miRNA-29a was accompanied by a decrease in serum levels of DPP4, but there was no significant difference between moderate and severe conditions. Furthermore, the levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and platelet were higher in UC patients relative to those without UC.

Conclusions: These findings supported the role of the miRNA-29a-DPP4 axis in the pathogenesis of UC and provide the evidence for the further evaluation of this axis as biomarkers of the disease.
