Deregulating cellular energetics by reprogramming metabolic pathways, including arginine metabolism, is critical for cancer cell onset and survival. Drugs that target the specific metabolic requirements of cancer cells have emerged as promising targeted cancer therapeutics. In this study, we investigate the therapeutic potential of targeting colon cancer cells using arginine deprivation induced by a pegylated cobalt-substituted recombinant human Arginase I [HuArgI (Co)-PEG5000].
