Exhaled Breath Condensate for Proteomic Biomarker Discovery
نویسندگان
چکیده
Exhaled breath condensate (EBC) has been established as a potential source of respiratory biomarkers. Compared to the numerous small molecules identified, the protein content of EBC has remained relatively unstudied due to the methodological and technical difficulties surrounding EBC analysis. In this review, we discuss the proteins identified in EBC, by mass spectrometry, focusing on the significance of those proteins identified. We will also review the limitations surrounding mass spectral EBC protein analysis emphasizing recommendations to enhance EBC protein identifications by mass spectrometry. Finally, we will provide insight into the future directions of the EBC proteomics field.

Background and Objective: The collection of exhaled breath condensate (EBC) is a noninvasive, safe and simple technique to obtain direct samples from lung and use for estimation of the effects of air pollution on human subjects. EBC contains several compounds including simple ions, hydrogen peroxide, proteins, cytokines, deoxyribonucleic acid (DNA), creatine, Electrolytes, trace elements and to...
متن کاملExhaled biomarkers in lung cancer.
Lung cancer is the leading cause of cancer death. Results of therapeutic interventions are particularly discouraging when the disease is discovered in an advanced stage. Early diagnosis is limited by the fact that the disease usually develops asymptomatically and available screening methods do not fulfil the requirements for reliable discrimination between patients with lung cancer and subjects...

متن کاملInfluence of condensation temperature on selected exhaled breath parameters
BACKGROUND The effects of changes in cooling temperature on biomarker levels in exhaled breath condensate have been little investigated. The aim of the study was to test the effect of condensation temperature on the parameters of exhaled breath condensate and the levels of selected biomarkers. METHODS Exhaled breath condensate was collected from 24 healthy subjects at temperatures of -10, -5,...
