Respiratory disease accounts for a large proportion of emergency admissions to hospital and diseaseassociated mortality. Genetic association studies demonstrate a link between iron metabolism and pulmonary disease phenotypes. IREB2  is a gene that produces iron regulatory protein 2 (IRP2), which has a key role in iron homeostasis. This review addresses pathways involved in iron metabolism, particularly focusing on the role of IREB2 . In addition to this, environmental factors also influence phenotypic variation in respiratory disease, for example inhaled iron from cigarette smoke is deposited in the lung and causes tissue damage by altering iron homeostasis. The effects of cigarette smoke are detailed in this article, particularly in relation to lung conditions that favour the upper lobes, such as emphysema and lung cancer. Clinical applications of iron homeostasis are also discussed in this review, especially looking at the pathophysiology of chronic obstructive pulmonary disease, lung cancer, pulmonary infections and acute respiratory distress syndrome. Promising new treatments involving iron are also covered.

Disease Epidemiology

Chronic obstructive pulmonary disease (COPD), the frequently fatal pathology of the respiratory tract, accounts for half a billion cases globally. COPD manifests via chronic inflammatory response to irritants, frequently to tobacco smoke. The progression of COPD from early onset to advanced disease leads to the loss of the alveolar wall, pulmonary hypertension, and fibrosis of the respiratory epithelium. Here, we focus on the epidemiology, progression, and biomarkers of COPD with a particular connection to lung cancer. Dissecting the cellular and molecular players in the progression of the disease, we aim to shed light on the role of smoking, which is responsible for the disease, or at least for the more severe symptoms and worse patient outcomes. We summarize the inflammatory conditions, as well as the role of EMT and fibroblasts in establishing a cancer-prone microenvironment, i.e., the soil for ‘COPD-derived’ lung cancer. We highlight that the major health problem of COPD can be alleviated via smoking cessation, early diagnosis, and abandonment of the usage of biomass fuels on a global basis.

Chronic Obstructive Pulmonary Disease (COPD) and Lung cancer are the major reasons for lung disease-related mortality worldwide. Chronic inflammation is a key attribute of COPD and a potential driver of lung carcinogenesis. Among various environmental risk factors, cigarette smoke plays a crucial role in the development and progression of COPD and lung cancer. Several epidemiological studies show that COPD patients are at a greater risk of developing lung cancer independently of cigarette smoking which suggests the role of genetic predisposition in the disease development. Uncovering the mechanistic link between these two diseases is hampered due to their heterogeneous nature: each is characterized by several sub-phenotypes of diseases. This review focuses on the nature of the link between the two diseases and specific mechanisms that occur in both COPD and lung cancer, some of the therapeutic targets which are currently employed, and the role of gene-editing technology to combat these debilitating lung-inflammatory disorders.
