Schwartz et al. found that some key genes in the GSH system, such as glutathione peroxidase 3 (GPX3), glutaredoxin (GLRX), and superoxide dismutase (SOD2), were expressed at higher levels in OCCC cells and were significantly increased when tumor cells were exposed to chemotherapeutic agents like platinum [68, 75]. Here, GPX3 is linked to neoplasm.
