Abstract

Historically, it has been challenging to go beyond epidemiology to investigate the pathogenic changes caused by tobacco smoking. The EpiAirway-100 (MatTek Corp., Ashland, MA) was employed to investigate the effects of cigarette smoke components. Exposure at the air-liquid-interface represented particle and vapour phase components of cigarette smoke. A proteomic study utilising iTRAQ labelling compared expression profiles. The correlative histopathology revealed focal regions of hyperplasia, hypertrophy, cytolysis and necrosis. We identified 466 proteins, 250 with a parameter of two or more peptides. Four of these proteins are potential markers of lung injury and three are related to mechanistic pathways of disease.
