Abstract
Lysosomes are crucial cellular organelles for human health that function in
digestion and recycling of extracellular and intracellular macromolecules.
We describe a signaling role for lysosomes that affects aging. In the worm
Caenorhabditis elegans, the lysosomal acid lipase LIPL-4 triggered nuclear
translocalization of a lysosomal lipid chaperone LBP-8, which promoted
longevity by activating the nuclear hormone receptors NHR-49 and NHR-80. We
used high-throughput metabolomic analysis to identify several lipids in
which abundance was increased in worms constitutively overexpressing LIPL-4.
Among them, oleoylethanolamide directly bound to LBP-8 and NHR-80 proteins,
activated transcription of target genes of NHR-49 and NHR-80, and promoted
longevity in C. elegans. These findings reveal a lysosome-to-nucleus
signaling pathway that promotes longevity and suggest a function of
lysosomes as signaling organelles in metazoans.
