Our data is in line with previous reports of several IPF pathogenic pathways, namely the WNT pathway38,39 (e.g. FZD5, SFRP1, SFRP2) and migratory associated processes40–42 (e.g Thy1, MMP13, ADAMTSL3) that respond to the IPF environment. The gene discussed is THY1; the disease is idiopathic pulmonary fibrosis.
