(Submitter supplied) Background: MicroRNAs (miRNAs) acting as negative regulators of gene expression are differentially expressed in intestinal tissues of patients with inflammatory bowel disease (IBD). Assessing the functional role of miRNAs in murine models of colitis facilitates elucidating the role of specific miRNAs in human IBD. The aim of this study was to determine the miRNA signature of murine models of colitis and to assess the influence of miR-21 on intestinal inflammation. more...

(Submitter supplied) Background: It has been found that miR-21 is increased in colonic tissues and decreased in peripheral blood regulatory T cells (Tregs) of patients with ulcerative colitis (UC). We aimed to investigate the influence of miR-21 on Tregs function in intestinal inflammation. Methods: Various CD4+ T cell populations were flow-cytometry sorted from miR-21-/- mice and littermates (WT) utilization in T-cell transfer colitis model and suppression of T cell activation and proliferation by Tregs. more...

(Submitter supplied) To further development of gene expression in inflammatory bowel disease(IBD), we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish IBD patients and healthy volunteers. Colon biopsies were obtained from IBD patients and healthy volunteers during endoscopy. There were 353 genes that showed greater than 4-fold differential expression (285 upregulated and 68 downregulated) between IBD patients and healthy volunteers.

(Submitter supplied) Primary biliary cholangitis (PBC), formally known as primary biliary cirrhosis, is an autoimmune liver disease of unknown pathogenesis. Consequently, therapeutic targets for PBC have yet to be identified. As CD4+ T cells play a pivotal role in immunological dysfunction observed in PBC, we analyzed microRNA(miRNA) and mRNA expression in CD4+ T cells to investigate PBC pathogenesis and identify novel therapeutic targets.

(Submitter supplied) microRNAs are assumed to fine-tune cellular mRNA expression levels predisposing them for the control of cell development and cell fates. However, despite increasing appreciation of the role of miRNAs in controlling myeloid cell functions and some evidence for their contribution in in vitro monocyte differentiation, the in vivo role of specific miRNAs in the development and homeostasis of myeloid cells remains to be investigated. more...

(Submitter supplied) 2 types of dendritic cells (DCs) can be generated in vitro in the presence of Flt3-L: CD4+ equivalent CD24- DCs and CD8+ equivalent CD24+ DCs. miR-142-/- mice show a severe defect in the generation of CD4+ equivalent CD24- DCs. To understand the underlying mechanism, RNA expression was analyzed by Affymetrix microarray from the 2 in vitro subtypes of DCs derived from miR-142+/+ and miR-142-/- bone marrow cells. more...

(Submitter supplied) MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression by either translational inhibition or mRNA degradation. However, the role of miRNAs in inflammation induced by flagellin (ligand of TLR5) has not been fully determined, Here, we identified differentially expressed miRNAs in murine bone marrow-derived dendritic cells (BMDCs) between flagellin (FliC) treatment and medium alone using miRNA microarray. more...
