β-Hydroxybutyrate induces bovine hepatocyte apoptosis via an ROS-p38 signaling pathway

β-Hydroxybutyrate (BHB) is an important indicator for metabolic disorders in dairy cows, such as ketosis and fatty liver. Dairy cows with ketosis display oxidative stress that may be associated with high levels of BHB. The purpose of this study was to demonstrate a correlation between the high levels of BHB and oxidative stress in dairy cows with ketosis, and to investigate the molecular mechanisms underlying oxidative damage in bovine...
