  1. De Lisle R, Mueller R, Boyd M. Impaired mucosal barrier function in the small intestine of the cystic fibrosis mouse. J Pediatr Gastroenterol Nutr. 2011;53:371-9 pubmed publisher
    ..Exogenous IAP improve permeability and strongly reduce bacterial overgrowth in CF mice, suggesting this may be a useful therapy for CF. ..
  2. De Lisle R. Disrupted tight junctions in the small intestine of cystic fibrosis mice. Cell Tissue Res. 2014;355:131-42 pubmed publisher
    ..These changes in TJ protein localization in CF are likely to be involved in the increased permeability of the CF small intestine to macromolecules and TNF? may be a causative factor. ..

    De Lisle R, Roach E, Norkina O. Eradication of small intestinal bacterial overgrowth in the cystic fibrosis mouse reduces mucus accumulation. J Pediatr Gastroenterol Nutr. 2006;42:46-52 pubmed
    ..Control of bacterial overgrowth is expected to reduce mucus accumulation and may improve intestinal function and overall health in CF. ..
  4. De Lisle R. Pass the bicarb: the importance of HCO3- for mucin release. J Clin Invest. 2009;119:2535-7 pubmed publisher
    ..The authors propose a model whereby CFTR-mediated bicarbonate secretion must be concurrent with mucin exocytosis for proper mucin release. ..

    ..These results suggest that both mucus accumulation and slowed interdigestive small intestinal transit contribute to SIBO in the CF intestine. ..
  6. De Lisle R, Mueller R, Roach E. Lubiprostone ameliorates the cystic fibrosis mouse intestinal phenotype. BMC Gastroenterol. 2010;10:107 pubmed publisher
    ..The unexpected observation of increased mucus accumulation in the crypts of lubiprostone-treated CF mice suggests the possibility that lubiprostone increases mucus secretion. ..

  1. Norkina O, Burnett T, De Lisle R. Bacterial overgrowth in the cystic fibrosis transmembrane conductance regulator null mouse small intestine. Infect Immun. 2004;72:6040-9 pubmed
    ..These data suggest that bacterial overgrowth in the CF mouse small intestine has a role in inflammation and contributes to the failure to thrive in this mouse model of CF. ..

    ..Overall, the data show that pro-Muclin acts as a sorting receptor that can induce RSG, and that its cytosolic tail is important in this process. ..

    ..Thus Muclin deficiency impairs trafficking of regulated proteins to a stimulus-releasable pool in the exocrine pancreas. ..
  4. De Lisle R, Meldi L, Roach E, Flynn M, Sewell R. Mast cells and gastrointestinal dysmotility in the cystic fibrosis mouse. PLoS ONE. 2009;4:e4283 pubmed publisher
    ..The results indicate that mast cells are not involved in gastrointestinal dysmotility but their activation can stimulate small intestinal transit in cystic fibrosis. ..
