Mucin gene expression in intestinal epithelial cells in Crohn's disease.
BACKGROUND Crohn's disease (CD) is a chronic relapsing inflammatory bowel disease of unknown origin. It is characterised by chronic mucosal ulcerations which affect any part of the intestine but most commonly are found in the ileum and proximal colon. AIMS Studies were undertaken to provide information regarding cell specific expression of mucin genes in the ileum of patients with CD. PATIE...
متن کاملMucin gene expression in colonic tissues and cell lines.
Complementary DNA clones encoding four different mucin core peptides have been isolated. However, the expression of these mucin genes in the colon has not been systematically studied. The present investigation used Northern blot analysis to study the expression of MUC1, MUC2, MUC3, and MUC4 mRNA in paired normal and cancerous colonic tissues, and nine colon cancer cell lines. Results were corre...
متن کاملThe VSL#3 probiotic formula induces mucin gene expression and secretion in colonic epithelial cells.
Several studies have stressed the importance of the microbiota in the maintenance of the gastrointestinal epithelium. Administration of probiotic bacteria, supplements composed of microbiota constituents, was previously shown to diminish symptoms in patients suffering from inflammatory bowel diseases. This raises the possibility that probiotics may play an active role in enhancing the intestina...
متن کاملNeuregulin-regulated gene expression in mammary carcinoma cells.
Recent studies have suggested that autocrine production of Neuregulin (NRG), a growth factor that activates members of the Epidermal Growth Factor Receptor/ErbB family of proto-oncogenes, is sufficient for breast tumor initiation and progression. To elucidate the molecular mechanisms regulating these events, we undertook a global analysis of genes regulated by NRG in luminal mammary epithelial ...
متن کاملMucin gene expression and mucin content in the chicken intestinal goblet cells are affected by in ovo feeding of carbohydrates.
The protective mucus layer covers the entire surface of the gastrointestinal tract. The mucus layer also acts as a medium for molecule transport between the luminal contents and the enterocytes; therefore it has a major role in nutrient absorption. The main mucus layer component, mucin glycoproteins, is produced by mucous-secreting goblet cells. In chicken small intestine, functional developmen...
