1 METHODS: Here we investigated the role of lumican in the development of colitis mediated by intrarectal administration of the hapten 2-4-5, trinitrobenzene sulfonic acid (TNBS) in Lum(+/+) and Lum(-/-) mice. Trinitrobenzenesulfonic Acid lumican Mus musculus
2 RESULTS: The TNBS treated Lum(+/+) mouse colons showed marked increases in CXCL1, tumor necrosis factor alpha (TNF-alpha), and neutrophil infiltration, whereas these responses were significantly dampened in the Lum(-/-) mice. Trinitrobenzenesulfonic Acid lumican Mus musculus
3 RESULTS: The TNBS treated Lum(+/+) mouse colons showed marked increases in CXCL1, tumor necrosis factor alpha (TNF-alpha), and neutrophil infiltration, whereas these responses were significantly dampened in the Lum(-/-) mice. Trinitrobenzenesulfonic Acid lumican Mus musculus
4 The nuclear factor kappa B (NF-kappaB) transcription factor, known to regulate inflammatory genes, showed a robust increase after TNBS treatment in Lum(+/+) but not in Lum(-/-) colons. Trinitrobenzenesulfonic Acid lumican Mus musculus
