Evaluation of Plasma Extracellular Vesicle MicroRNA Signatures for Lung Adenocarcinoma and Granuloma With Monte-Carlo Feature Selection Method
Conclusion
Extracellular Vesicle is a promising technology for non-invasive diagnosis. miRNAs processed by exosomes can be detected by liquid biopsy and used as biomarkers. To evaluate the discriminative ability of miRNAs from whole plasma, EV and EV-free plasma, we analyzed the miRNA expression profiles in whole plasma, EV and EV-free plasma of lung adenocarcinoma and granuloma patients. We found that the top discriminative miRNAs in whole plasma, EV and EV-free plasma were quite different, and the classification rules also varied. The prediction performance of whole plasma was the best but the EV outperformed EV-free plasma. Our results suggested that EV can be used as a lung cancer biomarker but EV may be less stable or difficult to detect than whole plasma, therefore, the whole plasma was still a good choice as lung cancer signatures.
