Moreover, Runx2 expression is highly increased in fibrotic alveolar epithelial type II (AT II) cells, but not affected in fibroblasts during the process of pulmonary fibrosis, suggesting that the role of Runx2 in regulating fibrosis‐associated genes is opposite between AT II cells and fibroblasts.16 The gene discussed is RUNX2; the disease is pulmonary fibrosis.
