Decreased β-catenin Protein in Lungs From Human Congenital Diaphragmatic Hernia Archival Pathology Specimens: A Case-control Study

In brief

This case-control study investigates Wnt signaling pathway alterations in human CDH lungs by measuring beta-catenin protein levels in archival pathology specimens. While animal models show disrupted Wnt signaling in CDH-associated lung hypoplasia, human data remains limited, making this translational research critical for understanding CDH pathophysiology.

• Lung hypoplasia is a major contributor to morbidity and mortality in congenital diaphragmatic hernia (CDH).
• Wnt-signaling pathway and β-catenin (CTNNB1) alterations are documented in animal CDH models but poorly characterized in humans.
• This study investigates whether Wnt-signaling gene expression is reduced in human CDH lungs compared to controls.
• β-catenin acts as a transcription coactivator and may be a therapeutic target if dysregulated in human CDH.
