Gremlin1 (p = 0.0011) (Myllärniemi et al., 2008a; Myllärniemi et al., 2008b) and Gremlin2 (p < 0.001) expressions in Group 1 (Figure 1B) were significantly high in the lung tissues of patients with fibrosis, while there was no difference in the expression of another BMP strong antagonist CHRD (p = 0.1819) between healthy people and patients with fibrosis. The gene discussed is CHRD; the disease is fibrosis.
