DNAH6 and idiopathic pulmonary fibrosis: The expression of cilium genes was closely correlated to MUC5B level and the extent of honeycombing in IPF patients, such as DNAH6 and DNAH7, which was associated with the cilia motility (Yang et al., 2013), and the biological module of cilia genes can also predict the survival of IPF patients (McDonough et al., 2019).
