This finding was later supported by the discovery that EZH2 and G9a also cooperate to regulate the repression of C-X-C motif chemokine ligand 10 (CXCL10) (Coward et al., 2018) another important factor in regulating pulmonary fibrosis (Tager et al., 2004). Here, CXCL10 is linked to pulmonary fibrosis.
