The protective effects of DL-Selenomethionine against T-2/HT-2 toxins-induced cytotoxicity and oxidative stress in broiler hepatocytes
2019
Abstract T-2 and HT-2 toxins can cause cytotoxicity and oxidative stress in animals, while DL-Selenomethionine plays an important role in preventing oxidative stress and improving cell viability. However, the role of DL-Selenomethionine in T-2/HT-2 toxins-induced cell damage is still unknown. In this study, we investigated whether DL-Selenomethionine plays a protective role against T-2/HT-2-induced cytotoxicity and oxidative stress in primary hepatocytes. Our results demonstrated that T-2/HT-2 toxins-exposed broiler hepatocytes exhibited significantly decreased cell viability and intracellular glutathione (GSH) concentration while increased Lacate dehydrogenase (LDH) leakage, intracellular reactive oxygen species (ROS), glutathione peroxidase (GSH-PX), malondialdehyde (MDA) and catalase (CAT) levels, as well as elevated expression levels of genes related to oxidative stress, in a toxin dose-dependent manner ( P P in vitro data demonstrate that DL-Selenomethionine can function as an effectively protective agent against T-2/HT-2-induced cytotoxicity and oxidative stress.
