Oncogenic PI3K Promotes Methionine Dependency in Breast Cancer Cells Through the Cystine-Glutamate Antiporter xCT

The precursor homocysteine is metabolized either through the methionine cycle to produce methionine or through the transsulfuration pathway to synthesize cysteine. Alternatively, cysteine can be obtained through uptake of its oxidized form, cystine. Many cancer cells exhibit methionine dependency su...
