Lung Cancer in Pulmonary Fibrosis: Tales of Epithelial Cell Plasticity

Abstract: Lung epithelial cells exhibit a high degree of plasticity. Alterations to lung epithelial cell function are critically involved in several chronic lung diseases such as pulmonary fibrosis. Pulmonary fibrosis is characterized by repetitive injury and subsequent impaired repair of epithelial cells, which leads to aberrant growth factor activation and fibroblast accumulation. Increased proliferation and hyper- and metaplasia of epithelial cells upon injury have also been observed in pulmonary fibrosis; this epith… Show more

“…It is important to investigate whether the expression of HS6ST2S contributes to the bronchiolar metaplasia process of the distal lung in IPF. In addition, bronchiolar metaplasia is thought to be a preneoplastic lesion, and IPF is frequently associated with the development of lung cancer (49). On this note, HS6ST2S has been shown to be overexpressed in pancreatic cancer, and silencing of HS6ST2S leads to inhibition of cell invasion and migration and to reduced tumorigenesis (50).…”

“…Secondly, Rexo2 is an RNA exonuclease and recently another similar enzyme, Xrn2 has been associated with murine lung cancer [19] through its involvement in epithelial cell proliferation. Impaired restoration of the alveolar epithelium following the initial stimulus is a potential trigger for pulmonary fibrosis [40,41], therefore variation in a gene implicated in alveolar cell proliferation could contribute to radiation-induced lung damage.…”

“…Cigarette smoking is the leading cause of lung cancer [6,7] and is related to almost 50–90% of cases [2]. Other risk factors are occupational exposure to carcinogens, passive smoking, air pollution, heavy metals, inorganic dusts, chemical compounds [2,8,9], airflow abstraction, emphysema [10] and pulmonary fibrosis [11]. …”
