651-S100A8/A9 and Hypothalamic Regulation of Cancer Cachexia
A research study published in Cell Metabolism investigates the biological mechanisms of cancer cachexia, a wasting syndrome characterized by severe muscle and adipose tissue loss. Using mouse models and human imaging, researchers discovered that while tumors increase their own metabolic activity, total energy expenditure remains stable because the body compensates by reducing energy use in the brain and kidneys. A critical finding is that tumors act as nutritional "sinks," acquiring protein and nitrogen from both dietary intake and the breakdown of host tissues. The study identifies a novel…
