The CDC25 protein phosphatases drive cell cycle advancement by activating cyclin-dependent protein kinases (CDKs). Humans and mice encode three family members denoted CDC25A, -B and -C and genes encoding these family members can be disrupted individually with minimal phenotypic consequences in adult mice. However, adult mice globally deleted for all three phosphatases die within one week after ...
Sphingosine-1 phosphate (S1P) is a potent bioactive lipid mediator that acts both as an intracellular signaling molecule and a natural ligand of five different G protein-coupled receptors (GPCRs), S1PR1-5. The level of S1P in intestinal tissue is abundant. Previous studies have reported that S1P protects intestinal epithelial cell from apoptosis by activating the ERK and Akt signaling pathways....
mantle cell lymphoma is an aggressive type of b-cell non-hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. the gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...
Glucocorticoids are steroid hormones with important functions in development, immune regulation, and glucose metabolism. The adrenal glands are the predominant source of glucocorticoids; however, there is increasing evidence for extraadrenal glucocorticoid synthesis in thymus, brain, skin, and vascular endothelium. We recently identified intestinal epithelial cells as an important source of glu...
Intestinal epithelial cells (IECs) perform several physiological and metabolic functions at the barrier. IECs also play an important role in defining overall immune mucosal region. Pattern recognition receptors (PRRs) on cell surface other cellular compartments enable them to sense presence of microbes microbial products intestinal lumen. are thus crossroads mediating a bidirectional interactio...
BACKGROUND Interleukin-6 (IL-6), a pluripotent cytokine, has traditionally been considered the product of proinflammatory cells. However, many other cell types have been shown to produce IL-6. Since intestinal inflammation is commonly associated with a vigorous systemic inflammatory response, we hypothesized that intestinal epithelial and smooth muscle cells might contribute to that response by...
PepT1 is a member of the proton-oligopeptide cotransporter family SLC15, which mediates the transport of di/tripeptides from intestinal lumen into epithelial cells. MicroRNAs (miRNAs), a small noncoding RNAs (21-23 nucleotides), post-transcriptionally regulate gene expression by binding to the 3'-untranslated regions (UTRs) of their target mRNAs. Although the role of most miRNAs remains elusive...
The impermeant nature of the intestinal barrier is maintained by tight junctions (TJs) formed between adjacent intestinal epithelial cells. Disruption of TJs and loss of barrier function are associated with a number of gastrointestinal diseases, including neonatal necrotizing enterocolitis (NEC), the leading cause of death from gastrointestinal diseases in preterm infants. Human milk is protect...
Epithelial cells of many mucosal organs have adapted to co-exist with microbes and microbial products. In general, most studies suggest that epithelial cell benefit from interactions with commensal microorganisms present at the lumenal surface. However, potentially injurious molecules found in this microenvironment also have the capacity to elicit local inflammatory responses and even systemic ...
The interaction of mucosal lymphocytes and intestinal epithelial cells is thought to be important in regulating immune response in the intestinal mucosa, but conclusive evidence is limited. Here we demonstrate the expression of IL-7 mRNA in human intestinal mucosa by combined reverse transcription PCR and Southern blot hybridization. Immunohistochemistry and in situ hybridization confirm the pr...
