Moreover, there was no difference in FUS mRNA and FUS protein expression in IPF patient–derived airway organoids with high MIR205HG and IL-33 expression relative to alveolar organoids with low MIR205HG and IL-33 expression (Figure 9B and Supplemental Figure 9, F and G). The gene discussed is FUS; the disease is idiopathic pulmonary fibrosis.
