RAS-driven oncogenesis is supported by downstream antioxidant programs.

In our recent study, we demonstrated that oncogenic RAS (rat sarcoma)-mediated transformation and tumorigenesis are supported by transcriptional induction of a crucial antioxidant component, SLC7A11 (solute carrier family 7 member 11), otherwise known as XCT, a gene encoding the cystine/glutamate transporter. Our data highlight that this promotes the biosynthesis of glutathione, in turn allowing RAS transformed cells to mitigate tumorigenesis-linked oxidative stress.
