26540405 Study demonstrated that the mRNA expression levels of the two system xc- subunits, SLC7A11 and SLC3A2, in peripheral white blood cells are lowered in patients with schizophrenia than healthy individuals
26254540 Sulfasalazine, a relatively non-toxic drug that targets cystine transporter, may, in combination with CDDP, be an effective therapy for colorectal cancer.
26252954 the rate of cystine uptake was significantly faster than the rate of glutamate release in human glioma cells.
26019222 increased SLC7A11 expression predicted shorter malignant glioma patient survival.
25860939 We discovered that many genes involved in oxidative stress/antioxidant defense system, apoptosis/anti-apoptosis/cell death, and cellular response to unfolded proteins/topologically incorrect proteins are potentially regulated by xCT.
25399695 Data indicate that cystine-glutamate exchange transporter protein SLC7A11 mRNA is regulated by cellular stress and nonsense-mediated RNA decay (NMD).
25002527 Results show that Nrf2 and ATF4 were upregulated by proteasome inhibition and cooperatively enhance human xCT gene expression upon proteasome inhibition.
24686172 IGF-I regulates cystine uptake and cellular redox status by activating the expression and function of xCT in estrogen receptor-positive (ER(+)) breast cancer cells by a mechanism that relies on the IGF receptor substrate-1 (IRS-1).
24516043 Our findings indicate that miRNA-27a negatively regulates SLC7A11 in cisplatin-resistant bladder cancer, and shows promise as a marker for patients likely to benefit from cisplatin-based chemotherapy
24094812 the xCT antiporter, which is expressed on one-third of triple-negative breast tumors in this study, may have a role in glutamine updake and dependence
