主 题：Crohn’s disease Ulcerative colitis Inflammatory bowel disease miRNA Differential diagnosis Biomarker
摘 要：BACKGROUND Inflammatory bowel disease(IBD)comprises two distinct diseases,Crohn’s disease(CD)and ulcerative colitis(UC),both of which are chronic,relapsing inflammatory disorders of the gastrointestinal tract with a mostly unknown *** incidence and prevalence of IBD are continually increasing,indicating the need for further studies to investigate the genetic determinants of these *** microRNAs(miRNAs)regulate protein translation via complementary binding to mRNA,discovering differentially expressed miRNAs(DE)in UC or CD patients could be important for diagnostic biomarker identification,assisting in the appropriate disease differentiation progressing the understanding of IBD *** To determine the miRNA expression profile in UC and CD patients and the potential pathophysiological contributions of differentially expressed *** A total of 20 formalin-fixed paraffin-embedded colonic samples were collected from the Pathology Department of Botucatu Medical School at São Paulo State University(Unesp).The diagnosis of UC or CD was based on clinical,endoscopic,radiologic,and histological criteria and confirmed by histopathological analysis at the time of *** TaqMan™Array Human MicroRNA A+B Cards Set v3.0(Applied Biosystems™)platform was used to analyze 754 *** of DE-miRNAs were predicted using miRNA Data Integration Portal(mirDIP)and the miRNA Target Interaction database(MiRTarBase).All statistical analyses were conducted using GraphPad Prism *** and nonparametric data were analyzed using t-tests and Mann-Whitney U tests,*** The results showed that of the 754 miRNAs that were initially evaluated,643 miRNAs were found to be expressed in at least five of the patients who were diagnosed with either CD or UC;the remaining 111 miRNAs were not considered to be expressed in these *** expression levels of 28 miRNAs were significantly different between the CD and UC patients(P≤0.05
