Meta-analytic evidence for the anti-aging effect of hormesis on Caenorhabditis elegans.

ABSTRACT: Mild stress-induced hormesis, as a promising strategy to improve longevity and healthy aging, meets both praise and criticism. To comprehensively assess the applicability of hormesis in aging intervention, this meta-analysis was conducted focusing on the effect of hormesis on Caenorhabditis elegans. Twenty-six papers involving 198 effect size estimates met the inclusion criteria. Meta-analytic results indicated that hormesis could significantly extend the mean lifespan of C. elegans by 16.7% and 25.1% under normal and stress culture conditions (p < 0.05), respectively. The healthspan assays showed that hormesis remarkably enhanced the bending frequency and pumping rate of worms by 28.9% and 7.0% (p < 0.05), respectively, while effectively reduced the lipofuscin
