synergistic detrimental effects when present with other risks that contribute to its
pathogenesis. Oxidative injury to the endothelium via reactive oxygen species (ROS) and
nitric oxide (NO) dysregulation is a common denominator of smoking-induced alterations in
vascular function. However, the mechanisms underlying ROS and NO dysregulation due to
smoking remain unclear. We tested if arginase (Arg) activation/upregulation contributes to …
