PGK1 enhances productive bovine herpesvirus 1 infection by stimulating β-catenin-dependent transcription

Abstract Bovine herpesvirus 1 (BoHV-1) productive infection stimulates β-catenin-dependent transcription to facilitate virus replication. Phosphoglycerate kinase 1 (PGK1), which catalyses the initial step of ATP

Article Description

The levels of cellular reactive oxygen species (ROS) and ATP as well as the mitochondrial membrane potential (MMP) in response to bovine herpesvirus 1 (BHV-1) infection of MDBK cells were measured, respectively. BHV-1 infection increased ROS production which depended on viral entry, and de novo protein expression and/or DNA replication. Vice versa, excessive ROS was required for efficient viral replication. Levels of both ATP and MMP were significantly decreased after BHV-1 infection. Interestingly, the loss of MMP was ameliorated by ROS depression. Collectively, ROS dependent mitochondrial damage and ultimately disruption of energy metabolism (ATP depletion) are a potential pathogenic mechanism for BHV-1 infection.
