1 Treatment with arsenite also induced reactive oxygen species (ROS) production, and pretreatment with a ROS scavenger N-acetyl-L-cysteine (NAC) completely reversed the observed effect of arsenite on eNOS-Thr(497) phosphorylation. Reactive Oxygen Species nitric oxide synthase 3 Bos taurus
2 Overall, our study demonstrates firstly that arsenite acutely decreases NO production at least in part by increasing eNOS-Thr(497) phosphorylation via ROS-PP1 signaling pathway, which provide the molecular mechanism underlying arsenite-induced increase in vascular disease. Reactive Oxygen Species nitric oxide synthase 3 Bos taurus
