The proper regulation of body size is of fundamental importance, but the mechanisms that stop growth are still unclear. Scientists have shed new light on how animals regulate body size. The researchers uncovered important clues about the molecular mechanisms triggered by environmental conditions that ultimately affect final body size. They show that the timing of synthesis of a steroid hormone called ecdysone is sensitive to nutrition in the fruit fly and describe the key proteins involved in this regulatory mechanism. This study explains what causes hormones to become environmentally-sensitive and provides important clues on body size regulation.
