The primary function of thioredoxin (Trx) is the reduction of oxidized cysteine residues and the cleavage of disulfide bonds. [10] Multiple in vitro substrates for thioredoxin have been identified, including ribonuclease, choriogonadotropins, coagulation factors, glucocorticoid receptor, and insulin.
The concept of antioxidative stress may best be described by excessive or detrimental nutritional consumption of a diet rich in antioxidants, [3] unbalancing the immune systems' pathogenic response processes. Serious health conditions can result if these processes are chronically unbalanced, ranging from acute to chronic.
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

Deferoxamine is produced by removal of the trivalent iron moiety from ferrioxamine B, an iron-bearing sideramine produced by the actinomycetes, Streptomyces pilosus.Its discovery was a serendipitous result of research conducted by scientists at Ciba in collaboration with scientists at the Swiss Federal Institute of Technology in Zurich and the University Hospital in Freiburg, Germany [15] [4 ...
Mutated p53 is involved in many human cancers, of the 6.5 million cancer diagnoses each year about 37% are connected to p53 mutations. [30] This makes it a popular target for new cancer therapies. Homozygous loss of p53 is found in 65% of colon cancers, 30–50% of breast cancers, and 50% of lung cancers.
Antioxidants & Redox Signaling is a peer-reviewed scientific journal covering reduction–oxidation (redox) signaling and antioxidant research. It covers topics such as reactive oxygen species/reactive nitrogen species (ROS/RNS) as messengers gaseous signal transducers, hypoxia and tissue oxygenation, microRNA, prokaryotic systems, and lessons from plant biology.
Coenzyme Q 10 (CoQ 10 / ˌ k oʊ k j uː ˈ t ɛ n /), also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. [1] [2] [3] It can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.
Antioxidants are reducing agents, and limit oxidative damage to biological structures by passivating them from free radicals. [ 4 ] Strictly speaking, the free radical theory is only concerned with free radicals such as superoxide ( O 2 − ), but it has since been expanded to encompass oxidative damage from other reactive oxygen species (ROS ...
