Cytokine production was evaluated in lamina propria mononuclear cells [LPMCs] of IBD patients and mucosal tissues of colitic mice treated with BRD4 inhibitors. Finally, we evaluated the effect of JQ1, an inhibitor of the BRD4 signalling pathway, on the course of murine colitis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>BRD4 RNA and protein expression was up-regulated in the inflamed mucosa of patients with UC and patients with CD as compared with the uninvolved areas of the same patients and CTRs, and in the inflamed colon of colitic mice. Knockdown of BRD4 with a specific antisense oligonucleotide in IBD LPMCs led to reduced expression of TNF-\u03b1, IL-6, IFN-\u03b3, and IL-17A.
