Inducible Nitric Oxide Synthase (iNOS) Mediates Vascular Endothelial Cell Apoptosis in Grass Carp Reovirus (GCRV)-Induced Hemorrhage.

ABSTRACT: Hemorrhage is one of the most obvious pathological phenomena in grass carp reovirus (GCRV) infection. The etiology of GCRV-induced hemorrhage is unclear. We found inducible nitric oxide synthase (iNOS) may relate to viral hemorrhage according to the previous studies, which is expressed at high levels after GCRV infection and is related to apoptosis. In this study, we aimed to investigate the mechanism of iNOS on apoptosis and hemorrhage at the cell level and individual level on subjects who were infected with GCRV and treated with S-methylisothiourea sulfate (SMT), an iNOS inhibitor. Cell structure, apoptosis rate, and hemorrhage were evaluated through fluorescence microscopy, Annexin V-FITC staining, and H&E staining, respectively. Cell samples and muscle tissues were
