The Role of an Acidic Peptide in Controlling the Oxidation Process of Walnut Oil

open access: yesFoods, 2019
Here, the mechanism of action of an antioxidant peptide rich in acidic amino acid residues in controlling lipid oxidation is discussed. Firstly, in the presence of this peptide, the fluorescence intensity of lipid peroxide in samples of walnut oil was ...

Antioxidant status in breast cancer patients of different ages after radiotherapy [PDF]

open access: yesArchives of Biological Sciences, 2009
In this study we investigated the effects of breast cancer radiotherapy on the antioxidant (AO) enzyme activities of copper, zinc superoxide dismutase (CuZnSOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR), as well as on ...

Superoxide Radicals in the Execution of Cell Death

open access: yesAntioxidants, 2022
Superoxide is a primary oxygen radical that is produced when an oxygen molecule receives one electron. Superoxide dismutase (SOD) plays a primary role in the cellular defense against an oxidative insult by ROS. However, the resulting hydrogen peroxide is

Beneficial Impact of an Extract from the Berries of Aronia melanocarpa L. on the Oxidative-Reductive Status of the Submandibular Gland of Rats Exposed to Cadmium

open access: yesAntioxidants, 2020
Oxidative stress underlies the pathomechanisms of toxic action of cadmium (Cd), including its damaging impact on the oral cavity. This study investigated whether the administration of an extract from Aronia melanocarpa L.

The Role of Peroxiredoxins in the Regulation of Sepsis

open access: yesAntioxidants, 2022
Oxidative stress, a result of a disturbance in redox homeostasis, is considered to be one of the main aggravating events in the pathogenesis of immune disorders.

The role of non-coding RNA in ferroptosis of liver cancer and its impact on lipid peroxidation

open access: yesFrontiers in Immunology
Ferroptosis is an iron-dependent programmed death caused by the imbalance of lipid peroxides in cells. Unlike apoptosis, autophagy and necrosis, ferroptosis is mainly induced by the small molecule compound erastin. The main characteristics of ferroptosis

Unveiling an unexpected superoxide-mediated photooxidation mechanism of squalene monohydroperoxides to squalene hydroperoxy cyclic peroxides through ESR and LC–MS/MS analyses

open access: yesScientific Reports, 2023
Lipid cyclic peroxides are a rarely reported and documented class of compounds in the human organism. Recently, we reported the formation of squalene (SQ) hydroperoxy cyclic peroxides derived from SQ monohydroperoxide isomers (SQ-OOHs) for the first time.

The glutathione peroxidase Gpx4 prevents lipid peroxidation and ferroptosis to sustain Treg cell activation and suppression of antitumor immunity

open access: yesCell Reports, 2021
Summary: T regulatory (Treg) cells are crucial to maintain immune tolerance and repress antitumor immunity, but the mechanisms governing their cellular redox homeostasis remain elusive.
