Dynamic changes in the expression of MicroRNA-31 during inflammatory bowel disease-associated neoplastic transformation

Abstract

Our study reveals specific miR dysregulation as chronic inflammation progresses to dysplasia. MiR-31 expression levels increase with disease progression and accurately discriminates between distinct pathological entities that coexist in IBD patients. The novel effect of miR-31 on regulating factor inhibiting hypoxia inducible factor 1 expression provides a new insight on the pathogenesis of IBDN.
