Abstract

BACKGROUND: Crohn's disease (CD) is a chronic relapsing inflammatory bowel disease of unknown origin. It is characterised by chronic mucosal ulcerations which affect any part of the intestine but most commonly are found in the ileum and proximal colon. AIMS: Studies were undertaken to provide information regarding cell specific expression of mucin genes in the ileum of patients with CD. PATIENTS AND METHODS: Expression of mucin genes was analysed in the ileal mucosa of patients with CD and controls by in situ hybridisation and immunohistochemistry. RESULTS: In healthy ileal mucosa, patients with CD showed a pattern identical to normal controls with main expression of MUC2 and MUC3 , lesser expression of MUC1 and MUC4 , and no expression of MUC5AC , MUC5B , MUC6 , or MUC7 . In the involved mucosa, the pattern was somewhat comparable although heterogeneous to that observed in healthy ileal mucosa. Importantly, a particular mucin gene expression pattern was observed in ileal mucosa close to the ulcer margins in ulcer associated cell lineage, with the appearance of MUC5AC and MUC6 mRNAs and peptides, which are normally restricted to the stomach ( MUC5AC and MUC6 ) and duodenum ( MUC6 ), and disappearance of MUC2 . CONCLUSIONS: Our results suggest that gel forming mucins (more particularly MUC5AC and MUC6) may have a role in epithelial wound healing after mucosal injury in inflammatory bowel diseases in addition to mucosal protection.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
