A. Schema showing auranofin shifting of intracellular redox towards an oxidizing state by diminishing regeneration of reduced thioredoxin. B. Schema showing related path by which thioredoxin reductase inhibition increases intracellular hydrogen peroxide (H2O2). Particular importance of NADPH regeneration from NADP+ in glioblastoma metabolism and growth is reviewed in ref. 313.
