It’s reported that the CRGs, such as FDX1, LIAS, DLD, PDHA1, PDHB, DLAT, and LIPT1, were down-regulated in the lung tissues of pulmonary fibrosis mouse model, and the same results were obtained via analysis of lung tissues scRNA-seq data for human pulmonary fibrosis (23). This evidence concerns the gene DLD and pulmonary fibrosis.
