Redox therapy is an experimental therapy [1] [2] that aims to effect an outcome by modifying the levels of pro-oxidant and antioxidant agents in cells. [3] The term "redox" is a contraction of "reduction-oxidation". For cancer patients, the therapy is predicated on the idea that the redox state of cells may have an effect on cancer development. [4]
High amount of aerobic glycolysis (also known as the Warburg effect) distinguishes cancer cells from normal cells.The conversion of glucose to lactate rather than metabolizing it in the mitochondria through oxidative phosphorylation, (which can also occur in hypoxic normal cells) persists in malignant tumor despite the presence of oxygen.
NRF2 is a basic leucine zipper (bZIP) protein that may regulate the expression of antioxidant proteins that protect against oxidative damage triggered by injury and inflammation, according to preliminary research. [6] In vitro, NRF2 binds to antioxidant response elements (AREs) in the promoter regions of genes encoding cytoprotective proteins. [7]
In terms of cancer prevention, a 2019 study found that participants with the highest intake of lutein and zeaxanthin had the lowest risk of colorectal cancer. Vitamin A Salmon is rich in vitamin A ...
Spinach contains numerous types of antioxidants that guard against cancer, heart disease and Type 2 diabetes. ... and mood regulation, that are controlled by your gut microbiome.
The use of antioxidants to prevent some diseases is controversial. [59] In a high-risk group like smokers, high doses of beta carotene increased the rate of lung cancer since high doses of beta-carotene in conjunction of high oxygen tension due to smoking results in a pro-oxidant effect and an antioxidant effect when oxygen tension is not high.
Cancer cells with elevated ROS levels depend heavily on the antioxidant defense system. ROS-elevating drugs further increase cellular ROS stress level, either by direct ROS-generation (e.g. motexafin gadolinium, elesclomol) or by agents that abrogate the inherent antioxidant system such as SOD inhibitor (e.g. ATN-224, 2-methoxyestradiol) and ...
Oxidation response is stimulated by a disturbance in the balance between the production of reactive oxygen species and antioxidant responses, known as oxidative stress. Active species of oxygen naturally occur in aerobic cells and have both intracellular and extracellular sources.
