Besides, levels of peroxisome proliferator-activated receptor γ coactivator-1α (PGC1α) and mitochondrial transcription factor A (TFAM) are steadily inhibited in IPF cells (Hecker et al., 2014; Bernard et al., 2015, 2017; Caporarello et al., 2019). This evidence concerns the gene TFAM and idiopathic pulmonary fibrosis.
