Fra2 TG mice possess strong activation of IL-13 downstream signaling. (A) Western blot analysis and quantification of phosphorylated (p) and total STAT6 levels in lung homogenates of Fra2 TG and WT mice (n = 5 per group); α-Tubulin (α-TUB) is shown as a loading control, ^***p < 0.001. (Uncropped scans of the original membranes can be found in Figure E2) (B) Representative immunohistochemical staining (from n = 5) against pSTAT6 (brown).
