Copied from Pulmonary fibrosis{[Pulmonary fibrosis involves gradual exchange of normal lung parenchyma with fibrotic tissue. The replacement of normal lung with scar tissue causes irreversible decrease in oxygen diffusion capacity, and the resulting stiffness or decreased compliance makes pulmonary fibrosis a restrictive lung disease. Pulmonary fibrosis is perpetuated by aberrant wound healing, rather than chronic inflammation. It is the main cause of restrictive lung disease that is intrinsic to the lung parenchyma. In contrast, quadriplegia and kyphosis are examples of causes of restrictive lung disease that do not necessarily involve pulmonary fibrosis.]}

Common genes implicated in fibrosis are Transforming Growth Factor-Beta (TGF-β), Connective Tissue Growth Factor (CTGF) , Epidermal Growth Factor Receptor (EGFR)  , Interleukin-13 (IL-13)  , Platelet-Derived Growth Factor (PDGF)  , Wnt/β-catenin signaling pathway.


 * TGF-β is a cytokine that plays a critical role in the regulation of extracellular matrix (ECM) production and cellular differentiation . It is a potent stimulator of fibrosis, and increased TGF-β signaling is associated with the development of fibrosis in various organs.
 * CTGF is a matricellular protein that is involved in ECM production and remodeling . It is up-regulated in response to TGF-β and has been implicated in the development of pulmonary fibrosis.
 * EGFR is a transmembrane receptor that plays a role in cellular proliferation, differentiation, and survival. Dysregulated EGFR signaling has been implicated in the development of pulmonary fibrosis, and drugs that target EGFR have been shown to have therapeutic potential in the treatment of the disease.
 * IL-13 is a cytokine that is involved in the regulation of immune responses . It has been shown to promote fibrosis in the lungs by stimulating the production of ECM proteins and the recruitment of fibroblasts to sites of tissue injury.
 * PDGF is a cytokine that plays a key role in the regulation of cell proliferation and migration . It is involved in the recruitment of fibroblasts to sites of tissue injury in the lungs, and increased PDGF signaling is associated with the development and progression of pulmonary fibrosis.
 * Wnt/β-catenin signaling plays a critical role in tissue repair and regeneration, and dysregulated Wnt/β-catenin signaling has been implicated in the development of pulmonary fibrosis.
