Figure Lengend Snippet: Fig. 4. TAK1 activation in IMF of CD patients. A: Western blotting analysis of phosphorylated (p)TAK1 in specimens obtained from normal ileum (n 9) or stenotic segments of CD patients (n 15) and relative densitometric analysis. B: tissue sections of ileum obtained from control patients with right colon carcinoma (n 9) or stenotic segments of CD patients (n 15) were stained for pTAK1. -SMA was used as a myofibroblast marker (scale bars, 23.8 m). Arrows, pTAK1 -SMA myofibroblasts. C: Western blotting of pTAK1 in IMF derived from control subjects and CD patients (n 4–5 cell lines for each group) and relative densitometric analysis. D: immunocytochemical analysis of pTAK1 in control and CD-derived IMF (scale bars, 37.5 m; n 3 cell lines for each group). E: Western blotting analysis of pTAK1 on CD-derived IMF treated with 10 g/ml anti-TGF- neutralizing antibody (ab) for 3.5 h and relative densitometric analysis (n 4). Data are reported as means SE. ***P 0.001, **P 0.05, and *P 0.01 vs. control.
