Children and other vertebrate animals stunted due to malnutrition can compensate for this deficit by resuming growth at a higher-than-normal rate via a still ill-defined mechanism. High mortality and adverse effects later in life may offset the positive effects of catch-up growth. Here we report that the invertebrate Drosophila melanogaster also experiences catch-up growth following a period of starvation, and the relaxin receptor Lgr4 instigates this catch-up growth. Starved larvae compensate for weight loss by growing two or more times faster and starting maturation within the same time as the non-starved sibling by preventing a rise in insulin-like growth (IGF)-induced ecdysone under Lgr4 control. Our data reveal that catch-up growth is associated with a surge of insulin, not IGF, which may clarify how catch-up growth often leads to metabolic problems and obesity.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
