The mechanisms that maintain the epithelial integrity of the gastrointestinal tract remain largely undefined. The gene encoding intestinal trefoil factor (ITF), a protein secreted throughout the small intestine and colon, was rendered nonfunctional in mice by targeted disruption. Mice lacking ITF had impaired mucosal healing and died from extensive colitis(More)
The trefoil gene family of mucus cell-secreted proteins is a critical mediator of gastrointestinal mucosal restitution. Transcription of trefoil genes is induced during mucosal repair, but the regulatory mechanisms involved are unknown. Mice deficient in the intestine-specific peptide intestinal trefoil factor (ITF), in which colonic restitution is lethally(More)
The results of application of flow cytometry (FCM) in analysis of 139 bladder irrigations of DNA contents in tumor cells from 52 cases of bladder tumors are reported. A comparison was made between this assay and cytological examinations as well as pathological grading. The results suggested that the accuracy of cytological analysis was apparently lower than(More)
The cellular DNA contents of 139 bladder irrigations from 52 cases of bladder tumors were determined by flow cytometry. The results were compared with those of pathological grading and exfoliative cytology. It is suggested that cytological results were less accurate than DNA contents. High aneuploid DNA contents in tumor cells were marked by low grade and(More)
