Lipid peroxidation in cell death.

Biochemical and Biophysical Research Communications - BBRC, 2017
Disruption of redox homeostasis is a key phenotype of many pathological conditions. Though multiple oxidizing compounds such as hydrogen peroxide are widely recognized as mediators and inducers of oxidative stress, increasingly, attention is focused on ...

Antioxidant Effects of Grape Vine Cane Extracts from Different Chinese Grape Varieties on Edible Oils

Molecules, 2014
This study involved the determination of the peroxide value (POV) as a measure of the resistance of the oxidation of edible oil with grape vine cane additives to assess their antioxidation potential.

Anisidine value as a measurement of the latent damage of fats

Grasas y Aceites, 1991
Although the peroxide value is a common measurement of lipid oxidation, its use is limited to the initial stages of oxidation. Since peroxides are vulnerable to further decomposition, the complete oxidative history of the oil may not be revealed.

Oxidation of human low density lipoprotein results in derivatization of lysine residues of apolipoprotein B by lipid peroxide decomposition products.

Journal of Biological Chemistry, 1987
Modification of low density lipoproteins (LDL) by oxidation has been shown to permit recognition by the acetyl-LDL receptor of macrophages. The extensive oxidation of LDL that is required before interaction occurs with this receptor produces major ...

Effect of Traditional Drying Methods on Proximate Composition, Fatty Acid Profile, and Oil Oxidation of Fish Species Consumed in the Far‐North of Cameroon

Global Challenges, 2020
The purpose of this study is to evaluate the effects of two traditional drying methods on proximate composition, lipid oxidation, and fatty acid composition of two freshwater fish species from Maga Lake in Cameroon.

Oxidative damage of U937 human leukemic cells caused by hydroxyl radical results in singlet oxygen formation.

PLoS ONE, 2015
The exposure of human cells to oxidative stress leads to the oxidation of biomolecules such as lipids, proteins and nuclei acids. In this study, the oxidation of lipids, proteins and DNA was studied after the addition of hydrogen peroxide and Fenton ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Lipid Oxidation in Dispersive Systems with Monoacylglycerols

Czech Journal of Food Sciences, 2009
Model fat blends with a monoacylglycerol emulsifier with different acyl chain (C10, C12, C14, C16, C18, C18:1, C20, C22) were prepared and stored under oxygen atmosphere 8 weeks at temperature 20°C.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
