then asked whether DR longevity critically requires peroxisome function, specifically peroxisome protein import, using PRX-5 TPD. Animals on DR lived significantly longer as expected. However, we saw a complete abrogation of DR longevity in animals with induced PRX-5 degradation, showing that functional peroxisomes are a central requirement for DR longevity (
