The Role of MicroRNA in Inflammatory Bowel Disease
Abstract:
Inflammatory bowel disease (IBD) is the consequence of an abnormal immune response to environmental factors in genetically susceptible hosts. microRNAs (miRNAs) are small, 22-nucleotide, noncoding, single-stranded RNA molecules involved in the post-tran-scriptional regulation of 30% of protein-coding genes. Differential expression of miRNAs is described in multiple autoimmune-related conditions such as psoriasis, rheumatoid arthritis, lupus, and asthma. Recently, unique miRNA expression profiles have been described in epithelial cells of patients with active ulcerative colitis, Crohn's ileitis, and Crohn's colitis, as well as in the peripheral blood of patients with active ulcerative colitis and Crohn's disease. miRNA expression profiles also change in the progression from normal colonic tissue to dysplastic tissue, with unaffected tissue from IBD patients and inflamed tissue from IBD patients showing intermediate profiles. Understanding the role of miRNAs in IBD may lead to future insights into disease pathogenesis, diagnosis, and treatment.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
Inflammatory Bowel Disease I: Introduction
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
