  "summary": "The metabolic environment of a tumor is shaped by the nutrients available in its interstitial fluid, yet the redox composition of that fluid is poorly defined. Measuring sulfur metabolites in the interstitial fluid of tumors, matched healthy organs, and serum across three mouse models of cancer, we find that the tumor microenvironment (TME) is a chemically reduced compartment in which free…",
