Project Title:Reducing the metabolic burden of rRNA synthesis promotes healthy longevity
Project Summary:Ribosome biogenesis is an anabolic process driven by RNA polymerase I (Pol I)-mediated synthesis of pre-ribosomal RNA (pre-rRNA). While Pol I activity was previously linked to longevity, the underlying mechanisms were not studied beyond effects on protein translation and downstream proteostasis. Here we used multi-omics and functional tests to show that curtailment of Pol I activity preserves mitochondrial function and lowers ATP expenditure, thereby promoting longevity in Caenorhabditis elegans. Reduced pre-rRNA synthesis also improved longevity and energy homeostasis in Drosophila melanogaster and human cells, respectively. Conversely, the enhancement of pre-rRNA synthesis boosted growth and neuromuscular performance of young nematodes at the cost of accelerated metabolic decline, mitochondrial stress and premature aging. Moreover, restriction of Pol I activity extended lifespan more potently than translational repression, and retained its geroprotective effects when initiated late in life, showcasing moderation of Pol I activity as an effective longevity treatment not limited by aging.

Collection:

Collection ID:CO002404
Collection Summary:Worms were washed and pelleted, M9 media was removed with ~100 µl remaining in the sample, and the sample was snap frozen.
Sample Type:Worms

Treatment:

Treatment ID:TR002423
Treatment Summary:Ncl-1 and tif-IA knockdown was achieved by feeding the worms for 2 generations with bacteria (from the Ahringer RNAi feeding library, Source BioScience Ltd.) producing the corresponding dsRNA. Worms were cultured under standard conditions as described in ‘Wormbook’, F1 was grown at 15°C and F2 at 20°C, and F2 animals were grown on RNAi until days 2, 6 or 12 of adulthood.

Sample Preparation:

Sampleprep ID:SP002417
Sampleprep Summary:Phospholipids were extracted from C. elegans by successive addition of PBS pH 7.4, methanol, chloroform, and saline to a final ratio of 14:34:35:17. Evaporation of the organic layer yielded a lipid film that was dissolved in methanol and subjected to UPLC-MS/MS.
