Exploration of microRNA Biomarkers in Blood Small Extracellular Vesicles for Enzootic Bovine Leukosis.

ABSTRACT: Enzootic bovine leukosis (EBL) is a B-cell lymphosarcoma caused by the bovine leukemia virus (BLV). While most infected cattle show no clinical signs, approximately 30% of infected cattle develop persistent lymphocytosis (PL), and a small percentage may develop EBL. Currently, there is no method for predicting the possibility of EBL onset. In this study, we analyzed the microRNAs (miRNAs) encapsulated in small extracellular vesicles (sEVs) in the blood to explore the biomarkers of EBL. To identify candidate biomarkers, blood samples were collected from three BLV-uninfected and three EBL cattle. Total RNA was extracted from filtered serum and used for microarray analysis. Due to their association with cancer in human orthologs, we selected three miRNAs as candidate biomarkers, bta-miR-17-5p
