1 Hippocampal slices exposed to various ROS and NO donors resulted in increases in levels of the active forms of both p42 MAPK and p44 MAPK. Reactive Oxygen Species mitogen-activated protein kinase 3 Homo sapiens
2 The ROS- and NO-enhanced tyrosine phosphorylation and activation of p42 MAPK and p44 MAPK were inhibited by pretreatment with the antioxidant N-acetyl-L-cysteine. Reactive Oxygen Species mitogen-activated protein kinase 3 Homo sapiens
3 Our observations indicate that ROS and NO can mediate protein tyrosine phosphorylation and MAPK signaling in the hippocampus via a redox-sensitive mechanism and suggest a potential cellular mechanism for their effects in the nervous system. Reactive Oxygen Species mitogen-activated protein kinase 3 Homo sapiens
