Role of Inflammatory and Proresolving Mediators in Endothelial Dysfunction
Basic &Clinical Pharmacology &Toxicology, Volume 136, Issue 5, May 2025.ABSTRACT Excessive local inflammation is a common mechanism in many cardiovascular diseases (CVDs) such as hypertension, atherosclerosis and aortic aneurysms. In endothelial cells, inflammatory cytokines such as interferons, tumour necrosis factor alpha or interleukins increase oxidative stress and contractile prostanoids and the expression of adhesion

New Phytologist, Volume 246, Issue 3, Page 901-910, May 2025.Summary Nectar, a vital mediator of plant–pollinator interactions, exhibits remarkable chemical diversity beyond sugars, including reactive oxygen species and specialized metabolites such as pigments. Colored nectars, present in over 70 species, function as visual signals, inhibitors of microbial growth, or nutritional rewards, underscoring their ...

Indirect Antioxidant Effects of the Nitrite Anion: Focus on Xanthine Oxidase
Advances in Redox Research, 2023 One electron reduction of nitrite (NO2−) has been determined to be a significant, noncanonical source of nitric oxide (NO) with molybdopterin enzymes being identified as critical to this process. Of the molybdopterin enzymes identified as NO2− reductases,

Plant, Cell &Environment, Volume 48, Issue 5, Page 3559-3572, May 2025.ABSTRACT Nitrate reduction requires reducing equivalents produced by the photosynthetic electron transport chain. Therefore, it has been suggested that nitrate assimilation provides a sink for electrons under high light conditions. We tested this hypothesis by monitoring photosynthetic efficiency and the chloroplastic glutathione redox potential (chl ...

Superoxide reductase from Desulfoarculus baarsii: reaction mechanism and role of glutamate 47 and lysine 48 in catalysis [PDF]
Biochemistry, American Chemical Society, 2001, pp.5032-40, 2015 Superoxide reductase (SOR) is a small metalloenzyme that catalyzes reduction of O(2)(*)(-) to H(2)O(2) and thus provides an antioxidant mechanism against superoxide radicals. Its active site contains an unusual mononuclear ferrous center, which is very efficient during electron transfer to O(2)(*)(-) [Lombard, M., Fontecave, M., Touati, D., and Nivi ...
