Altered Prostasin (CAP1/Prss8) Expression Favors Inflammation and Tissue Remodeling in DSS-induced Colitis.

Inflamm Bowel Dis 2016 12;22(12):2824-2839

*Département de Pharmacologie and de Toxicologie, University of Lausanne, Lausanne, Switzerland; Sumedha Malsure is now with the Elanco Animal Health, Basel, Switzerland; and †Institut Universitaire de Pathologie, University Hospital of Lausanne (CHUV), Lausanne, Switzerland.

Background: Inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn's disease are diseases with impaired epithelial barrier function. We aimed to investigate whether mutated prostasin and thus, reduced colonic epithelial sodium channel activity predisposes to develop an experimentally dextran sodium sulfate (DSS)-induced colitis.

Methods: Wildtype, heterozygous (fr/+), and homozygous (fr/fr) prostasin-mutant rats were treated 7 days with DSS followed by 7 days of recovery and analyzed with respect to histology, clinicopathological parameters, inflammatory marker mRNA transcript expression, and sodium transporter protein expression.

Dig Dis Sci 2016 09 10;61(9):2732-40. Epub 2016 Jun 10.

Division of Digestive Diseases, David Geffen School of Medicine at UCLA, Ronald Reagan UCLA Medical Center, Los Angeles, CA, USA.

Background: The sites of origin, causes and outcomes of severe hematochezia have not been compared between cirrhotics and non-cirrhotics.
