Human, bronchoalveolar lavage, extracellular vesicles


ABSTRACT: The aim of the project was to explore large extracellular vesicles capacity to seperate non lung cancer from lung cancer cases. A case control study of patients suspected for lung cancer (12 non lung cancer and 12 lung cancers). The raw files are labeled according to clinical status. Small and large extracellular vesicles were isolated by differential centrifugation. The proteome of full BAL, vesicle depleted BAL, small and large extracellular vesicles were characterized by LC-MS. Small extracellular vesicles were further analyzed by nanoparticle tracking analysis, Transmission electron microscopy and western blots.

Acellular bronchoalveolar lavage (BAL) proteomics can partially separate lung cancer from non-lung cancer patients based on principal component analysis and multivariate analysis. Furthermore, the variance in the proteomics data sets is correlated mainly with lung cancer status and, to a lesser extent, smoking status and gender. Despite these advances BAL small and large extracellular vehicles (EVs) proteomes reveal aberrant protein expression in paracrine signaling mechanisms in cancer initiati  ...[more]
