Slc3a2tm1.1Merl/Slc3a2+ Tg(Vil1-cre)997Gum/0 mice are protected from dextran sodium sulfate-induced colitis

mortality/aging
decreased susceptibility to xenobiotic induced morbidity/mortality ( J:173946 )
• in mice treated with azoxymethane and DSS

digestive/alimentary system
abnormal enterocyte proliferation ( J:173946 )
• mice treated with azoxymethane and DSS exhibit reduced colonic epithelial cell proliferation compared with control mice
decreased susceptibility to induced colitis ( J:173946 )
• DSS-treated mice exhibit reduced weight loss, decreased rectal bleeding, no diarrhea, reduced colon shortening, reduced crypt damage and fewer inflammatory infiltrates and ulcerations compared with control mice

neoplasm
decreased incidence of tumors by chemical induction ( J:173946 )
• mice treated with azoxymethane and DSS exhibit fewer and smaller adenomas than in control mice
