Petroleum coke exposure leads to altered secretome profiles in human lung models.

ABSTRACT: Petroleum coke (PC) is a coal-like product that is produced during the refinement of crude oil and bituminous sand. Fugitive dust from open storage of PC in urban areas is a potential human health concern. Animal inhalation studies suggest that PC leads to an adverse pulmonary histopathology, including areas of fibrosis and chronic inflammation; however, little is known about its impact on human health. In order to identify biomarkers and cellular pathways that are associated with exposure, we performed two-dimensional liquid chromatography-mass spectrometric analyses on secreted proteins from two human lung culture models. A total of 2795 proteins were identified and relatively quantified from an immortalized cell line and 2406 proteins from primary cultures that were either mock treated
