Closer inspection revealed that 3 of 13 significantly overexpressed miRNAs in the IPF lung fibroblasts are due to treatment with TGF-β1 (Figure 8B), with the other 10 miRNAs present as baseline difference between the IPF and normal lung fibroblasts (Figure 8B). The gene discussed is TGFB1; the disease is idiopathic pulmonary fibrosis.
