Cancer Pro-oxidant Therapy Through Copper Redox Cycling: .

Authors:
Manuel Rieber

Curr Pharm Des 2020 ;26(35):4461-4466

IVIC, Cancer Cell Biology Laboratory, CMBC, Caracas 1020A, Venezuela.

Background: Copper (Cu) is a transition metal active in Fenton redox cycling from reduced Cu+ and H2O2, to oxidized Cu2+ and the hydroxyl radical (·OH) highly reactive oxygen species (ROS). At homeostatic Cu levels, ROS promote cell proliferation, migration, angiogenesis, and wound repair. To limit ROS toxicity, cells use Cu-dependent chaperone proteins, Cu-binding ceruloplasmin, and Cu-modulated enzymes like superoxide dismutases (SOD) like SOD1 and SOD3 to scavenge excess superoxide anions which favour Cu+ reduction, and mitochondrial cytochrome c oxidase, important in aerobic energy production.
