WebCystine Uptake and Expression of GCLC and GPX4 are Low GGT1 Dependent in ChRCC. Cysteine is a rate-limiting substrate for the synthesis of glutathione ( 30) and can be incorporated by cells as gamma-glutamyl cysteine, a product of GGT function. Cysteine can also be generated by reduction of cystine. WebIntroduction. Ferroptosis is a newly identified type of iron-dependent programmed cell death that was first reported by Dixon et al in 2012. 1 As a new type of programmed cell death, ferroptosis is different from apoptosis, autophagy, necrosis, pyrolysis and other forms of cell death in terms of morphology and biochemistry.
