1 Because tumor necrosis factor (TNF)-alpha is important in the pathogenesis of inflammatory bowel disease, we investigated the effect of mesalamine on TNF-alpha-regulated signal transduction and proliferation in intestinal epithelial cells. Mesalamine tumor necrosis factor Mus musculus
2 RESULTS: The antiproliferative effects of TNF-alpha were blocked by mesalamine. Mesalamine tumor necrosis factor Mus musculus
3 TNF-alpha and ceramide activation of MAP kinase were inhibited by mesalamine, whereas epidermal growth factor activation of MAP kinase was unaffected. Mesalamine tumor necrosis factor Mus musculus
4 TNF-alpha-stimulated NF-kappaB activation and nuclear translocation and the degradation of Ikappa-Balpha were blocked by mesalamine. Mesalamine tumor necrosis factor Mus musculus
5 CONCLUSIONS: Mesalamine inhibits TNF-alpha-mediated effects on intestinal epithelial cell proliferation and activation of MAP kinase and NF-kappaB. Mesalamine tumor necrosis factor Mus musculus
