Expression of Runx3 in the mouse jejunum. A, Relative expression levels of Runx3, Runx1, and Cbfβ mRNA in jejunums of WT and Runx3+/− mice. B, Runx3 protein levels in jejunums of WT and Runx3+/− mice. C, Quantitation of mucosal Runx3-expressing cell numbers in jejunums of WT and Runx3+/− mice. Results are from 2 independent experiments; each experiment included 4 mice per group. *P < .05 and **P < .01. PBS/PE, Sham sensitized but PE challenged; PE/PE, PE sensitized and challenged.
