Role of proteomics in the investigation of pulmonary fibrosis

Abstract

Pulmonary fibrosis arises as a consequence of aberrant remodeling and defective repair mechanisms within the lung. This destructive process is the cause of much of the morbidity and mortality in many pulmonary disorders. Unfortunately, therapeutic options are limited. A significant advancement in the management of patients with pulmonary fibrosis would be the identification of biomarkers for diagnosis, prognosis and prediction of patient response to therapy. Bronchoalveolar lavage is an ideal tissue target for the discovery of these potential biomarkers in pulmonary fibrosis. Integrative approaches using both gel- and mass spectrometry-based proteomic workflows will allow full coverage of this complex proteome, thereby unlocking this potential information as a clinical tool to aid diagnosis and guide treatment for individual patients with pulmonary fibrosis.
