Fetal tracheal occlusion (TO) is an emerging therapy that improves lung growth and reduces mortality, although substantial respiratory compromise persists in survivors. In this study, we used tracheal fluid in a fetal sheep model of CDH with TO for proteomic analysis with subsequent validation of findings in sheep lung tissue. We found that the proteomic profiles of CDH tracheal fluid was most similar to control lung and CDH\/TO lung most similar to TO lung. Among 118 proteins altered in CDH, only 11 were reciprocally regulated in CDH\/TO. The most significantly altered pathways and processes were cell proliferation, phosphatidylinositol 3-kinase\/AKT\/mammalian target of rapamycin signaling, inflammation, and microtubule dynamics. CDH suppressed and TO promoted cell proliferation and AKT-related signaling cascades. By Western blot analysis and immunohistochemistry, epithelial PCNA and phosphorylated AKT were decreased in CDH and increased in TO and CDH\/TO lungs. The Wnt target Axin2 was decreased threefold in CDH lung compared with control without a significant increase in CDH\/TO lung. Cilia-related pathways were among the most dysregulated with CDH lung having a nearly twofold increase in acetylated \u03b1-tubulin and a relative increase in the number of ciliated cells. While TO improves lung growth and patient survival in CDH, the procedure substantially alters many processes important in lung development and cell differentiation. Further elucidation of these changes will be critical to improving lung health in infants with CDH treated with TO.
