The pro-inflammatory cytokine interleukin (IL)-6 (refs. 1–5) can bind to cells lacking the IL-6 receptor (IL-6R) when it forms a complex with the soluble IL-6R (sIL-6R) (trans signaling). Here, we have assessed the contribution of this system to the increased resistance of mucosal T cells against apoptosis in Crohn disease (CD), a chronic inflammatory(More)
BACKGROUND High-mobility group box-1 (HMGB1) is a nuclear factor released by necrotic cells and by activated immune cells. HMGB1 signals via members of the toll-like receptor family and the receptor for advanced glycation end products (RAGE). Although HMGB1 has been implicated in ischemia/reperfusion (I/R) injury of the liver and lung, its role in I/R(More)
The balance between pro and antiinflammatory cytokines secreted by T cells regulates both the initiation and perpetuation of inflammatory bowel diseases (IBD). In particular, the balance between interferon (IFN)-gamma/interleukin (IL)-4 and transforming growth factor (TGF)-beta activity controls chronic intestinal inflammation. However, the molecular(More)
The mRNA of the ubiquitin-like modifier FAT10 has been reported to be overexpressed in 90% of hepatocellular carcinoma (HCC) and in over 80% of colon, ovary and uterus carcinomas. Elevated FAT10 expression in malignancies was attributed to transcriptional upregulation upon the loss of p53. Moreover, FAT10 induced chromosome instability in long-term in vitro(More)
Heme oxygenase-1 (HO-1) is believed to represent a key enzyme for the protection of cells against "stress." Its overexpression in different types of human cancers supports the notion that HO-1 provides a growth advantage and contributes to cellular resistance against chemotherapy and radiotherapy. Given the poor survival rates of patients with pancreatic(More)
Diarrhea predominant irritable bowel syndrome (IBS-D) is a complex disorder related to dysfunctions in the serotonergic system. As cis-regulatory variants can play a role in the etiology of complex conditions, we investigated the untranslated regions (UTRs) of the serotonin receptor type 3 subunit genes HTR3A and HTR3E. Mutation analysis was carried out in(More)
Changes of the intestinal mucosal barrier are considered to play a role in the pathogenesis of inflammatory bowel disease (IBD). Our experiments were designed to identify dysregulation of epithelial junctional molecules in the IBD intestinum and to address whether altered expression of these molecules is a primary event in IBD or a phenomenon secondary to(More)
Restorative proctocolectomy and ileal pouch–anal anastomosis is the surgical treatment of choice for patients with ulcerative colitis. As a long-term complication of this procedure, chronic pouchitis impairs the outcome in a number of patients. Aneuploidia and dysplasia have been observed after long-lasting inflammation of ileal mucosa. The question arises(More)
Oxidative and carbonyl stress leads to generation of N(epsilon)-carboxymethyllysine-modified proteins (CML-mps), which are known to bind the receptor for advanced glycation end products (RAGE) and induce nuclear factor (NF)-kappaB-dependent proinflammatory gene expression. To determine the impact of CML-mps in vivo, RAGE-dependent sustained NF-kappaB(More)
OBJECTIVE To analyze the association between pre- and perioperative factors and pouch-related septic complications (PRSC) in ulcerative colitis (UC) and in familial adenomatous polyposis (FAP) after ileal pouch-anal anastomosis (IPAA). SUMMARY BACKGROUND DATA For patients with UC and FAP, IPAA is the surgical therapy of choice, but in some patients the(More)
