Peroxynitrite activates ERK via Raf-1 and MEK, independently from EGF receptor and p21Ras in H9C2 cardiomyocytes [PDF]

, 2005
Peroxynitrite is a potent oxidant and nitrating species proposed as a direct effector of myocardial damage in a wide range of cardiac diseases. Whether peroxynitrite also acts indirectly, by modulating cell signal transduction pathways in the myocardium,

Endogenous Amplification of Apoptosis via p53 Regulation using a Cascade Nanocatalytic Medicine

Advanced Science, EarlyView.
An engineered MOF nanomedicine (MAL) triggers cascade nanocatalysis in tumors, converting H2O2 and L‐Arg into cytotoxic peroxynitrite. This induces DNA damage, activates the p53 pathway, and amplifies mitochondrial apoptosis via the BAX/Bcl‐2/Caspase‐3 axis, effectively inhibiting colorectal cancer growth with high biocompatibility.

Tyrosine nitration in prostaglandin H2 synthase

Journal of Lipid Research, 2002
In this study, we investigated the effects of various nitrogen oxide (NOx) species on the extent of prostaglandin H2 synthase-1 (PGHS-1) nitration in purified protein and in vascular smooth muscle cells.

One-electron oxidation and reduction of glycosaminoglycan chloramides: a kinetic study. [PDF]

, 2013
Hypochlorous acid and its acid-base counterpart, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, these being significant components of the extracellular matrix (ECM).

Leishmanicidal activity of peroxynitrite

Redox Report, 1995
Nitric oxide reacts with superoxide to produce peroxynitrite which has been reported to be highly microbicidal to Trypanosoma cruzi in phosphate buffer but ineffective against Leishmania major in culture medium. This contradiction and the potential importance of peroxynitrite as a cytotoxic effector molecule of both macrophages and neutrophils led us ...

Therapeutic Gases in Biomedicine: Updates on Nitric Oxide and Beyond

Advanced Science, EarlyView.
Therapeutic gases, including NO, CO, H2S, H2, CO2, O2, and Xe, play vital roles in cellular signaling and repair. This review highlights the emerging carriers and delivery systems that enable controlled, localized gas release for diagnostic and therapeutic applications.

Nitric Oxide, Peroxynitrite and Malondialdehyde Levels as Markers for Nitrosative/Oxidative Stress in Iraqi Patients with Systemic Lupus Erythematosus

Iraqi Journal of Pharmaceutical Sciences, 2017
Systemic lupus Erythematosus is an autoimmune disease of unknown aetiology affecting multiple organ system. Reactive nitrogen and oxygen species are claimed to play a role in this disease.

Reaction of peroxynitrite with thiols, hydrogen sulfide and persulfides

Redox Biochemistry and Chemistry
Three decades of research on the biochemistry of peroxynitrite (ONOOH/ONOO−) have established that this stealthy oxidant is formed in biological systems, and that its main targets are carbon dioxide (CO2), metalloproteins and thiols (RSH).

A computational model for analysis of uncoupled NO synthase on nitric oxide and superoxide interaction in microcirculation [PDF]

, 2007
Nitric oxide (NO) produced by endothelial cells is a key component for blood-vessel dilation. Dilation is achieved through smooth muscle relaxation as a response to NO transport.

Semiconducting Polymer Nanoparticles Enable Light‐Controlled Bidirectional Modulation of Nitric Oxide in Endothelial Cells

Advanced Science, EarlyView.
Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.
