We selected 19 genes related to IPF (not necessarily associated with gene expression in lung tissues) to visualize their gene expression: CCL1815, CXCL1216, CXCL1317, collagens (COL1A1, COL1A2, COL3A1, COL5A2, COL14A1)18, DSP19, FAS20, IL-821, MMP122, MMP223, MMP722, MUC5B19, SPP124, PTGS225, TGFB126 and THY127. The gene discussed is COL1A2; the disease is idiopathic pulmonary fibrosis.
