Astaxanthin promotes the longevity of Caenorhabditis elegans via modulation of the intracellular redox status and PHA-4-mediated autophagy

Astaxanthin extends the lifespan and health span of C. elegans . Astaxanthin elevates skn-1 expression and oxidative stress resistance in C. elegans . The lifespan extension by astaxanthin depends on PHA-4-mediated autophagy.
