They were allowed to acclimate to the environment for at least 7 days. Mice were given unrestricted access to standard mouse chow and tap water. Yonezawa (Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama, Japan). DICAM knockout mice were kindly provided by Dr. MATERIALS AND METHODS AnimalsĪll experiments were carried out using 8-week-old male C57BL/6 mice purchased from Hana experimental animal service (Daegu, Korea). Here, we examined the expression of DICAM in normal and colitis murine model, which was induced by dextran sulfate sodium (DSS), and studied if the change in DICAM expression affects the severity of colonic inflammation. 9 Thus, it is plausible to hypothesize that DICAM may be involved in intestinal barrier function. 9 The phylogenetic analysis of DICAM indicates high homology with the JAMs family-major components of junctional complexes in epithelial cells. 10, 11 DICAM was reported to be expressed in epithelial cells of various organs, including intestine. 9 This novel protein is a negative regulator of osteoclast differentiation and angiogenesis where integrin αVß3 plays a critical role. 4ĭual immunoglobulin domain-containing adhesion molecule (DICAM) is a protein with homology to the JAMs involved in cell-cell adhesion via heterophilic interactions with integrin αVß3. It controls the epithelial integrity and maintains an intact barrier function. 6–8 The junctional adhesion molecule-A (JAM-A) is one of the main molecules in the tight junction that plays a unique role in IBD. Several studies have reported morphological and structural changes of tight junctions in UC and CD patients. 5 Several transmembrane and intracellular proteins such as occludin, claudin, junctional adhesion molecule family (JAMs), zonula occludens (ZO) family, and cingulin constitute tight junctions. They prevent paracellular permeation of dangerous luminal agents. Tight junctions play a crucial role and are semipermeable gates that regulate the paracellular solutes and water flux. These epithelial cells are joined by an apical junctional complex containing tight junctions and adherent junctions. The completeness of the intestinal barrier is maintained by a single layer of intestinal epithelial cells-which are the interface between tissue compartments and environmental luminal contents. Second, this impaired intestinal barrier allows uptake of high amounts of large molecular antigens that may initiate or aggravate inflammation. First, small solutes and water flowing into the lumen can cause leak flux diarrhea, which is the main symptom of IBD. 1–4īarrier dysfunction can lead to 2 consequences. Although the etiology and pathophysiology of IBD remain unclear, data suggest that the impaired epithelial barrier function observed in patients with IBD might play an important role in disease pathogenesis. Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is characterized by chronic intestinal inflammation with unpredictable courses and complicated management. in the Catalog.Adhesion molecule, colitis, DICAM, mucosal barrier INTRODUCTION The subprogram is designed to train public health professionals for leadership in the analysis of public health data and the design of studies for public health investigations.

The department has research expertise representing a broad array of methodological areas of statistics and biostatistics, including clinical trials, computational statistics, Bayesian modeling and inference, high-dimensional data analysis, statistical genetics and genomics, bioinformatics, informatics, statistical and machine learning, spatial and spatio-temporal modeling, time series analysis, survival data analysis, longitudinal data analysis, network analysis, causal inference, comparative effectiveness studies, model selection, epidemic modeling, and syndromic surveillance. The department also provides training for non-biostatistics students.īiostatistics faculty members work closely with both clinical and basic science investigators on the University of Iowa health sciences campus in the design and analysis of research projects. Graduates find positions in pharmaceutical, health care, and research companies and institutions in universities and government agencies and as consultants.
