摘要

Various signals, including those stemming from nutrients such as carbohydrates and amino acids, tightly coordinate cell growth. These signals can be altered in disease states, such as obesity and cancer. Reporting in Science, Bar-Peled et aV identify a protein complex called GATOR that is crucial for linking nutrient sensing by the cell to the control of cell growth. They also find that this complex is disrupted in some cancers, hinting at a mechanism by which cancer cells disconnect their growth from normal growth-control signals.
