IFNG and neoplasm: Other studies have shown that solute carrier family 7 member 11 (SLC 7A 11) and solute carrier family 3 member 2 (SLC 3A 2) are inhibited by interferon gamma (IFN γ) released from CD 8+T cells, thereby inhibiting cystine uptake by tumor cells, reducing the activity of GPX 4, and activating the process of lipid peroxidation in tumor cells (22).
