9-TB up-regulates airway epithelial SPLUNC1 protein in CC10-_CAIKKβ transgene positive (Tg+) mice.

<p>Lungs from saline-treated Tg+ mice were processed for SPLUNC1 immunohistochemistry. Representative SPLUNC1 staining in medium-size airways of Tg+ mice treated with vehicle solution (<b>A</b>) and 9-TB (<b>B</b>). Quantitative data of airway SPLUNC1 protein (<b>C</b>) are expressed as a percentage of stained area versus total (stained plus non-stained) airway epithelial area. N = 4 mice per group. Data are expressed as means ± SEM.
