Insect hormone PTTH regulates lifespan through temporal and spatial activation of NF-κB signaling during metamorphosis.

The prothoracicotropic hormone (PTTH) is a well-known neuropeptide that regulates insect metamorphosis (the juvenile-to-adult transition) by inducing the biosynthesis of steroid hormones. However, the role of PTTH in adult physiology and longevity is largely unexplored. Here, we show that loss-of-function mutants are long-lived and exhibit increased resistance to oxidative stress in .
