Compared with normoxia, miR-155 expression was increased by hypoxia in both healthy and IPF fibroblasts (Fig E9, C); however, LXRα and ABCA1 expression was increased by hypoxia only in IPF fibroblasts (Fig E9, D), suggesting selective deregulation of LXRα function. The gene discussed is NR1H3; the disease is idiopathic pulmonary fibrosis.
