Glutathione in metastases: From mechanisms to clinical applications.

2016

Metastatic spread, not primary tumors, is the leading cause of cancer death. Glutathione (γ-glutamyl-cysteinyl-glycine, GSH) is particularly relevant in cancer cells as it is involved in regulating carcinogenic mechanisms, growth and dissemination, and multidrug and radiation resistance. Upon interaction of metastatic cells with the vascular endothelium, a high percentage of metastatic cells with high GSH levels survive the combined nitrosative and oxidative stresses elicited by the vascular endothelium. GSH release from different organs, mainly the liver, and its interorgan transport through the blood circulation to metastatic foci, promote their growth. This review focuses on the relation…
