Summary

It is a mystery how multicellular organisms regulate the size of their cells and their overall mass. A number of papers, using the fruit fly Drosophila as a model system, now show that different molecules along the pathway that transduces signals from the insulin receptor and its ligand are involved in regulating cell size and growth rate. Sally Leevers ties together the findings of these different studies in an illuminating Perspective.
