Several ER stress-related genes (Figure 7D), claudin family genes (Figure 7E), S100 family genes (Figure 7F), as well as keratin family genes (Figure 7G) were upregulated in IPF AEC2s which are the orthologous genes upregulated in the mouse subset AEC2-3. The gene discussed is S100A1; the disease is idiopathic pulmonary fibrosis.
