Nitric Oxide in Health and Disease of the Nervous System H-Y Yun1,2, VL Dawson1,3,4 and TM Dawson1,3
Molecular Psychiatry (1997) 2, 300–310 1997 Stockton Press All rights reserved 1359–4184/97 $12.00 PROGRESS Nitric oxide in health and disease of the nervous system H-Y Yun1,2, VL Dawson1,3,4 and TM Dawson1,3 Departments of 1Neurology; 3Neuroscience; 4Physiology, Johns Hopkins University School of Medicine, Baltimore, MD, USA Nitric oxide (NO) is a widespread and multifunctional biological messenger molecule. It mediates vasodilation of blood vessels, host defence against infectious agents and tumors, and neurotransmission of the central and peripheral nervous systems. In the nervous system, NO is generated by three nitric oxide synthase (NOS) isoforms (neuronal, endothelial and immunologic NOS). Endothelial NOS and neuronal NOS are constitutively expressed and acti- vated by elevated intracellular calcium, whereas immunologic NOS is inducible with new RNA and protein synthesis upon immune stimulation. Neuronal NOS can be transcriptionally induced under conditions such as neuronal development and injury. NO may play a role not only in physiologic neuronal functions such as neurotransmitter release, neural development, regeneration, synaptic plasticity and regulation of gene expression but also in a variety of neurological disorders in which excessive production of NO leads to neural injury. Keywords: nitric oxide synthase; endothelium-derived relaxing factor; neurotransmission; neurotoxic- ity; neurological diseases Nitric oxide is probably the smallest and most versatile NO synthases isoforms and regulation of NO bioactive molecule identified. Convergence of multi- generation disciplinary efforts in the field of immunology, cardio- vascular pharmacology, chemistry, toxicology and neu- NO is formed by the enzymatic conversion of the guan- robiology led to the revolutionary novel concept of NO idino nitrogen of l-arginine by NO synthase (NOS). -
Nitric Oxide Produced by Ultraviolet-Irradiated Keratinocytes Stimulates Melanogenesis
Nitric oxide produced by ultraviolet-irradiated keratinocytes stimulates melanogenesis. C Roméro-Graillet, … , J P Ortonne, R Ballotti J Clin Invest. 1997;99(4):635-642. https://doi.org/10.1172/JCI119206. Research Article Ultraviolet (UV) radiation is the main physiological stimulus for human skin pigmentation. Within the epidermal-melanin unit, melanocytes synthesize and transfer melanin to the surrounding keratinocytes. Keratinocytes produce paracrine factors that affect melanocyte proliferation, dendricity, and melanin synthesis. In this report, we show that normal human keratinocytes secrete nitric oxide (NO) in response to UVA and UVB radiation, and we demonstrate that the constitutive isoform of keratinocyte NO synthase is involved in this process. Next, we investigate the melanogenic effect of NO produced by keratinocytes in response to UV radiation using melanocyte and keratinocyte cocultures. Conditioned media from UV-exposed keratinocytes stimulate tyrosinase activity of melanocytes. This effect is reversed by NO scavengers, suggesting an important role for NO in UV-induced melanogenesis. Moreover, melanocytes respond to NO-donors by decreased growth, enhanced dendricity, and melanogenesis. The rise in melanogenesis induced by NO-generating compounds is associated with an increased amount of both tyrosinase and tyrosinase-related protein 1. These observations suggest that NO plays an important role in the paracrine mediation of UV-induced melanogenesis.

Potential Roles of Nitrate and Nitrite in Nitric Oxide Metabolism in the Eye Ji Won Park1, Barbora Piknova1, Audrey Jenkins2, David Hellinga2, Leonard M
www.nature.com/scientificreports OPEN Potential roles of nitrate and nitrite in nitric oxide metabolism in the eye Ji Won Park1, Barbora Piknova1, Audrey Jenkins2, David Hellinga2, Leonard M. Parver3 & Alan N. Schechter1* Nitric oxide (NO) signaling has been studied in the eye, including in the pathophysiology of some eye diseases. While NO production by nitric oxide synthase (NOS) enzymes in the eye has been − characterized, the more recently described pathways of NO generation by nitrate ( NO3 ) and nitrite − (NO2 ) ions reduction has received much less attention. To elucidate the potential roles of these pathways, we analyzed nitrate and nitrite levels in components of the eye and lacrimal glands, primarily in porcine samples. Nitrate and nitrite levels were higher in cornea than in other eye parts, while lens contained the least amounts. Lacrimal glands exhibited much higher levels of both ions compared to other organs, such as liver and skeletal muscle, and even to salivary glands which are known to concentrate these ions. Western blotting showed expression of sialin, a known nitrate transporter, in the lacrimal glands and other eye components, and also xanthine oxidoreductase, a nitrate and nitrite reductase, in cornea and sclera. Cornea and sclera homogenates possessed a measurable amount of nitrate reduction activity. These results suggest that nitrate ions are concentrated in the lacrimal glands by sialin and can be secreted into eye components via tears and then reduced to nitrite and NO, thereby being an important source of NO in the eye. Te NO generation pathway from L-arginine by endogenous NOS enzymes under normoxic conditions has been central in identifying the physiological roles of NO in numerous biological processes1. -

Nitric Oxide Signaling in Plants
plants Editorial Nitric Oxide Signaling in Plants John T. Hancock Department of Applied Sciences, University of the West of England, Bristol BS16 1QY, UK; [email protected]; Tel.: +44-(0)117-328-2475 Received: 3 November 2020; Accepted: 10 November 2020; Published: 12 November 2020 Abstract: Nitric oxide (NO) is an integral part of cell signaling mechanisms in animals and plants. In plants, its enzymatic generation is still controversial. Evidence points to nitrate reductase being important, but the presence of a nitric oxide synthase-like enzyme is still contested. Regardless, NO has been shown to mediate many developmental stages in plants, and to be involved in a range of physiological responses, from stress management to stomatal aperture closure. Downstream from its generation are alterations of the actions of many cell signaling components, with post-translational modifications of proteins often being key. Here, a collection of papers embraces the differing aspects of NO metabolism in plants. Keywords: nitrate reductase; nitration; nitric oxide; reactive oxygen species; stress responses; S-nitrosation; S-nitrosylation; SNO-reductase; thiol modification 1. Introduction Nitric oxide (NO) is now well acknowledged as an instrumental signaling molecule in both plants and animals [1]. First recognized as important as a signal in the control of vascular tone [2], its role in plants came to prominence in the late 1990s [3–5]. The forty years of research into NO in plants has just been highlighted by a review by Kolbert et al. [6]. In plants, NO has been found to be involved in a wide range of developmental stages and physiological responses. -
