WebOct 11, 2006 · The cystine/glutamate exchanger (xCT) provides intracellular cyst(e)ine for production of glutathione, a major cellular antioxidant. Using xCT overexpression and underexpression, we present evidence that xCT-dependent glutathione production modulates both neuroprotection from oxidative stress and cell proliferation. In embryonic …
WebFeb 2, 2024 · In the present study, we found that autophagy has a selective role in sustaining cysteine (Cys) pools in PDAC. One of the major mechanisms of Cys homeostasis is through the import of cystine (the oxidized dimer of cysteine) through system x c −, a cystine/glutamate antiporter composed of SLC7A11 (xCT) and SLC3A2 .
There are many mechanisms that exist to regulate the expression of system Xc-, although it is not the sole determinate of extracellular glutamate or intracellular glutathione. An example is amino acid deprivation, which triggers up regulation of the transporter. A key regulator is extracellular glutamate; when it becomes excessive, it goes from an excitatory transmitter to an excitotoxin.
