Gation. Colonoscopy was performed applying a versatile digital ureteroscope around the day 7 of DSS therapy. For any complete FGFR4 MedChemExpress description, see SI Supplies and Approaches. BM Chimeric Mice. Mice getting BM transfer had been irradiated (900 radiation absorbed dose) right away prior to transplantation. BM was harvested from femurs and tibias of 4-wk-old SAMP or AKR mice. For a complete description, see SI Components and Techniques. Myeloperoxidase Assay Activity. Colon samples have been assayed for myeloperoxidase (MPO) activity as previously described (31, 32). For a complete description, see SI HPV Inhibitor site Materials and Approaches. Salmonella Infection Assays. Salmonella infection assays have been performed as previously described (9). To get a full description, see SI Supplies and Procedures. Salmonella Infection in Vivo. SAMP and AKR manage mice (4 wk) have been infected with Salmonella for two d. For a full description, see SI Materials and Approaches. Statistical Evaluation. Analyses of continuous information were conducted employing parametric Student t tests, one-way or two-way ANOVAs, or linear regression (when suitable), or their nonparametric options. For a complete description, see SI Components and Techniques. ACKNOWLEDGMENTS.
