Redox Signaling in Plants

Antioxidants & Redox Signaling, 2013
Our aim is to deliver an authoritative and challenging perspective of current concepts in plant redox signaling, focusing particularly on the complex interface between the redox and hormone-signaling pathways that allow precise control of plant growth and defense in response to metabolic triggers and environmental constraints and ...

Homocysteine and Redox Signaling

Antioxidants & Redox Signaling, 2005
Homocysteine is a thiol-containing amino acid that has gained notoriety because its elevation in the plasma is correlated with complex and multifactorial diseases, including cardiovascular diseases, neurodegenerative diseases, and neural tube defects.

Redox signaling in macrophages

Molecular Aspects of Medicine, 2001
Macrophages are phagocytic cells that produce and release reactive oxygen species (ROS) in response to phagocytosis or stimulation with various agents. The enzyme responsible for the production of superoxide and hydrogen peroxide is a multi-component NADPH oxidase that requires assembly at the plasma membrane to function as an oxidase.

Sodium in Mitochondrial Redox Signaling

Antioxidants & Redox Signaling, 2022
Background: Mitochondrial Na + has been discovered as a new second messenger regulating inner mitochondrial membrane (IMM) fluidity and reactive oxygen species (ROS) production by complex III (CIII). However, the roles of mitochondrial Na

Selenium and redox signaling

Archives of Biochemistry and Biophysics, 2017
Selenium compounds that contain selenol functions or can be metabolized to selenols are toxic via superoxide and H2O2 generation, when ingested at dosages beyond requirement. At supra-nutritional dosages various forms of programmed cell death are observed.

Photosensitization and Redox Signaling

Antioxidants & Redox Signaling, 2000
The effect of light in combination with a chemical or a natural compound is termed photosensitization, and is known to have multiple cellular effects. Among them, modulation of gene expression is one of the most important, because it directly influences cell adaptation to novel environmental conditions.

Subcellular Redox Signaling

2017
Oxidative and antioxidative system of cells and tissues maintains a balanced state under physiological conditions. A disruption in this balance of redox status has been associated with numerous pathological processes. Reactive oxygen species (ROS) as a major redox signaling generates in a spatiotemporally dependent manner.

Redox Signaling of Angiogenesis

Antioxidants & Redox Signaling, 2002
Reactive oxygen species (ROS) play a crucial role in vascular angiogenesis. Both in vitro and in vivo studies indicate that angiogenic response in vascular tissue is triggered by ROS signaling in a highly coordinated manner. It appears that massive amounts of ROS produced during ischemia and reperfusion in the vascular tissue, especially in heart ...

Lipid Rafts and Redox Signaling

Antioxidants & Redox Signaling, 2007
In addition to the amplifying action of enzymes in the cell-signaling cascade, another important mechanism has been shown to amplify the signals massively when ligands bind to their receptors, which is characterized by clustering of membrane lipid microdomains or lipid rafts and formation of various signaling platforms.

Redox Signaling in Cancer Biology

Antioxidants & Redox Signaling, 2006
Over the last three decades, it is has become increasing clear that intracellular signaling pathways are activated via changes in intracellular metabolic oxidation/reduction (redox) reactions involving reactive oxygen species (ROS; i.e., superoxide and hydrogen peroxide).
