Figure Lengend Snippet: Effects of matrine on intestinal pathology, inflammatory function, and JAK2 expression in experimental colitis mice Dextran Sulfate Sodium (DSS)-induced murine model of colitis was established in mice; matrine and 5-ASA treatment was administered as described. A – C Body weight and colon length were measured. D , E Histopathological alterations in colon tissues were evaluated using H & E staining; DAI scores were assigned according to the staining. F , G The levels of IL-1β, TNF-α, IL-6, MPO, NO, and MDA in colon tissues were examined using commercial assay kits. H , I The protein levels of JAK2 in mice colon tissues were determined using Immunohistochemical staining (IHC staining) and Immunoblotting. Magnification = 100 × or 200 × for IHC staining. J The protein levels of p-JAK2, p-STAT3, and STAT3 were detected using Immunoblotting. **p < 0.01, vs. PBS group; #p < 0.05, ##p < 0.01 vs. DSS group

Figure Lengend Snippet: Effects of JAK2 overexpression on intestinal epithelial cells upon inflammation MODE-K cells were transfected with a JAK2-overexpressing plasmid (JAK2 oe) or a control vector, with or without subsequent LPS stimulation. A The protein levels of JAK2 and p-JAK2 and the inflammatory factors IL-1β, TNF-α, and IL-6 were determined by Immunoblotting. B Cellular levels of MPO, NO, and MDA were measured using biochemical kits. C Intracellular ROS production was assessed by DCFH-DA staining and quantified with flow cytometry. D The protein levels of the bile acid metabolism-related factors FXR, MRP3 and MRP4 were examined by Immunoblotting. E The mRNA levels of MRP3, MRP4, OSTα, and OSTβ were measured by qRT-PCR. **p < 0.01 vs. Vector group; ##p < 0.01 vs. Vector group; &&p < 0.01 vs. LPS + Vector group
