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]
NRF2 appears to participate in a complex regulatory network and performs a pleiotropic role in the regulation of metabolism, inflammation, autophagy, proteostasis, mitochondrial physiology, and immune responses. [10] Several drugs that stimulate the NFE2L2 pathway are being studied for treatment of diseases that are caused by oxidative stress ...
Lipophilic antioxidants [3] and iron chelators [1] can prevent ferroptotic cell death. Researchers have identified roles in which oxytosis/ferroptosis can contribute to the medical field, such as the development of cancer therapies. [4] Ferroptosis activation plays a regulatory role on growth of tumor cells in the human body.
Lycopene is an antioxidant commonly found in tomatoes — it has been shown to prevent cell damage and provide myriad benefits to the body, including but not limited to helping improve sperm count.
Keap1 has been shown to interact with Nrf2, a master regulator of the antioxidant response, which is important for the amelioration of oxidative stress. [ 6 ] [ 7 ] [ 8 ] Under quiescent conditions, Nrf2 is anchored in the cytoplasm through binding to Keap1, which, in turn, facilitates the ubiquitination and subsequent proteolysis of Nrf2 .
Small changes in cellular oxidant status can be sensed by specific proteins which regulate a set of genes encoding antioxidant enzymes. Such a global response induces an adaptive metabolism including ROS elimination, the bypass of injured pathways, reparation of oxidative damages and maintenance of reducing power.
Cancer systems biology encompasses concrete applications of systems biology approaches to cancer research, notably (a) the need for better methods to distill insights from large-scale networks, (b) the importance of integrating multiple data types in constructing more realistic models, (c) challenges in translating insights about tumorigenic ...
Antioxidants are helpful in reducing and preventing damage from free radical reactions because of their ability to donate electrons which neutralize the radical without forming another. Vitamin C, for example, can lose an electron to a free radical and remain stable itself by passing its unstable electron around the antioxidant molecule.
