1 beta-catenin in the alveolar epithelium protects from lung fibrosis after intratracheal bleomycin. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
2 OBJECTIVES: We aimed to determine the role of beta-catenin in alveolar epithelium during bleomycin-induced lung fibrosis. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
3 MEASUREMENTS AND MAIN RESULTS: Increased beta-catenin expression was noted in lung parenchyma after bleomycin. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
4 Mice with selective deletion of beta-catenin in AECs had greater AEC death at 1 week after bleomycin, followed by increased numbers of fibroblasts and enhanced lung fibrosis as determined by semiquantitative histological scoring and total collagen content. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
5 In vitro, beta-catenin-deficient AECs showed increased bleomycin-induced cytotoxicity as well as reduced proliferation and impaired wound closure. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
6 Consistent with these findings, mice with AEC beta-catenin deficiency showed delayed recovery after bleomycin. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
7 CONCLUSIONS: beta-Catenin in the alveolar epithelium protects against bleomycin-induced fibrosis. Bleomycin catenin (cadherin associated protein), beta 1 Mus musculus
