Development of Competitive Enzyme-Linked Immunosorbent Assays for Antibody Detection Based on Bluetongue Virus Monoclonal Antibodies.

Bluetongue is a ruminant infectious disease that is characterized by hyperpyrexia, leukocyte decrease and mucosal ulcerative inflammation changes. In this study, three segments of Bluetongue virus (BTV)-8 VP2 protein (BTV-8A, 8B, and 8C) were cloned into pET-28a (+) and pMAl-c5X vectors and expressed in Escherichia coli BL21 (DE3) as histidine (His)-tagged (His-8A/8B/8C) and maltose-binding protein (MBP)-tagged (MBP-8A/8B/8C) fusion proteins. After purification, His-8A/8B/8C were used to immunize BALB/mice and MBP-8A/8B/8C were used to screen for monoclonal antibody (mAb)-secreting hybridomas.

MiR-490-5p Inhibits Hepatocellular Carcinoma Cell Proliferation, Migration and Invasion by Directly Regulating ROBO1.

Studies have investigated the effect of ROBO1. All the same, the relationship between miR-490-5p and ROBO1, and the underlying mechanism are still unclear. We aimed to study the effect of microRNA-490-5p (miR-490-5p) on hepatocellular carcinoma (HCC) cell proliferation, migration and invasion by directly regulating ROBO1.
