Locust corpora cardiaca contain an inactive adipokinetic hormone
. FEBS Letters, 447(2-3), 237-240.
Editor's Note: The researchers additionally determined that in flies genetically engineered to overexpress the hormone AKH (Adipokinetic Hormone
), metabolism and activity levels were enhanced and life span was extended, even without dietary restriction.
That happens because an enzyme called AMP-activated kinase stimulates the secretion of the adipokinetic hormone, which is the functional equivalent of glucagon.
Adipokinetic hormone is the insect equivalent to the hormone glucagon in the human pancreas.
