Quantification of Fascin-1-Positive Extracellular Vesicles by Nanoflow Cytometry for Early Detection of Hepatocellular Carcinoma in Liquid Biopsy.

ABSTRACT: Background: Hepatocellular carcinoma (HCC) lacks effective early diagnostic biomarkers. Identifying extracellular vesicles (EVs)-associated biomarkers for early HCC detection in HCC progression is precise and critical. Methods: Databases, tissue microarrays (TMA) were used to identify Fascin-1 as a candidate target for HCC, EVs isolated from tumoral and adjacent tissues. The tumor cells were transfected with lentivirus to obtain the engineered EVs. Results: Fascin-1-enriched EVs promoted HCC cell migration and induced cytoskeleton reorganization in vitro. Importantly, quantifying Fascin-1-positive EVs (Fascin-1⁺EVs) in patient plasma by nanoflow cytometry (nFCM) demonstrated high diagnostic performance (AUC=0.8925, 95%CI: 0.7959-0.9891) for discrimina
