Glutamine fuels a vicious cycle of autophagy in the tumor stroma and oxidative mitochondrial metabolism in epithelial cancer cells: implications for preventing chemotherapy resistance
These harmful actions lead to different forms of lung injury such as tissue damage, cell activation, and proliferation
Without the protection from oxidative injury afforded by glutathione, cells may be damaged or killed
