Moreover, although our results show that significantly elevated expression of COL27A1 and WNT11 was found in pulmonary fibrosis patients, we did not find any diagnostic or prognostic information related to these genes, indicating that further in vivo experiments and preclinical studies require to be carried out to explore their potential diagnostic and prognostic value in pulmonary fibrosis. The gene discussed is COL27A1; the disease is pulmonary fibrosis.
