Abstract/Description

Caloric restriction (CR), the reduction of nutrient intake short of malnutrition, extends the lifespan of various organisms and can improve measures of human health. Whether mechanisms of lifespan extension are conserved between humans and model organisms is unknown. In mammals, implementing CR is easily achieved by providing a restricted group with a fraction of the food consumed by an "ad libitum" fed group, which has unlimited food access. Due to the difficulty in directly controlling...
Show moreCaloric restriction (CR), the reduction of nutrient intake short of malnutrition, extends the lifespan of various organisms and can improve measures of human health. Whether mechanisms of lifespan extension are conserved between humans and model organisms is unknown. In mammals, implementing CR is easily achieved by providing a restricted group with a fraction of the food consumed by an "ad libitum" fed group, which has unlimited food access. Due to the difficulty in directly controlling Drosophila food intake, caloric restriction, performed similarly to the mammalian paradigm, has never been tested in flies. Here, we demonstrate a system that allows measurement of food intake throughout life. This system will be used to measure fly lifespan under caloric restriction analogous to current mammalian studies. Our work will help tease apart the differences between the various caloric and dietary restriction paradigms in Drosophila, strengthening our understanding of how fly models relate to mammalian systems.
