WebOct 14, 2024 · Oxidative stress in endothelial cells depletes BH4, switches NOS generation from NO to OO-, promotes formation of ONOO- from NO and OO-; dropping the intracellular ratio of BH4:BH2 inducing a feed forward cycle of more and more BH4 depletion and NOS-Uncoupling. Low levels of ONOO- exposure cause BH4 levels to drop by 60% in 500 … WebPeroxynitrite (ONOO −) is a potent bio-oxidant involved in many physiological and pathological processes; however, most of the pathological effects associated with ONOO − in vivo are still ambiguous.
