Microenvironmental InterFereNce of metabolism regulates chemosensitivity

Abstract

The tumor microenvironment is recognized as a critical regulator of cancer progression, and multiple roles are also emerging for the microenvironment in modulating response to therapeutic intervention. A recent study by Wang and colleagues identified IFN-γ as a central effector of CD8 T cell-mediated regulation of glutathione and cysteine metabolism in fibroblasts, which consequently abrogates stromal-induced resistance through modulation of cisplatin intracellular content in ovarian cancer cells.
