In this study, the expression of Wnt signaling molecules β-catenin, Wnt3A, inhibitor of β-catenin and T-cell factor (ICAT), Wnt5A/B, dishevelled associated activator of morphogenesis 1 (DAAM1), and nemo-like kinase (NLK) was examined in the lung parenchyma biopsies from 10 IPF patients and 7 healthy individuals. Here, CTNNBIP1 is linked to idiopathic pulmonary fibrosis.
