Background
The
Conclusions
The decreased ACSL5 and Wnt2B expressions correlated with aberrations in pulmonary development and in the pathogenesis of CPAM, so downregulation of ACSL5 and Wnt2B could play an important role in the development of bronchial-alveolar structures in CPAM.
Methods
Expression of ACSL5 and Wnt2B was evaluated by immunohistochemical staining, Western blotting, and quantitative real-time polymerase chain reaction, which were performed on surgical specimens of CPAM and adjacent normal lung tissues as controls.
Results
Immunohistochemistry revealed that ACSL5 and Wnt2B immunopositive cells were predominantly detected in the mesenchymal cell nucleus, and there were lower expressions of ACSL5 and Wnt2B immunopositive cells in CPAM tissues than those in adjacent normal lung tissues. Western blotting and quantitative real-time polymerase chain reaction showed that ACSL5 and Wnt2B protein and mRNA expressions were significantly decreased in CPAM tissues as compared to the adjacent normal lung tissues (P < 0.05). In addition, there was a reduced level of ACSL5 relative to that of Wnt2B. Conclusions: The decreased ACSL5 and Wnt2B expressions correlated with aberrations in pulmonary development and in the pathogenesis of CPAM, so downregulation of ACSL5 and Wnt2B could play an important role in the development of bronchial-alveolar structures in CPAM.
