Using epithelial cells from patients with idiopathic pulmonary fibrosis, Königshoff et al [15] showed that Western blot analysis of Wnt target gene products cyclin D1 and MMP-7 demonstrated increased functional Wnt/β-catenin signaling in pulmonary fibrosis compared with control patients. The gene discussed is CCND1; the disease is idiopathic pulmonary fibrosis.
