Aspirin has been revealed to have many beneficial effects for health since it was discovered as a nonsteroidal anti-inflammatory drug (NSAID) to treat pain and inflammation. Here, we investigated the molecular mechanism of aspirin on the lifespan extension of Caenorhabditis elegans. Our results showed that aspirin could extend the lifespan of C. elegans, and increase its health span and stress resistance. The extension of lifespan by aspirin requires DAF-16/FOXO, AMPK, and LKB1, but not SIR-2.1. Aspirin could not extend the lifespan of the mutants of eat-2, clk-1, and isp-1. Aspirin could marginally extend the lifespan of long-live insulin-like receptor mutant daf-2(e1370) III. Taken together, aspirin might act through a dietary restriction-like mechanism, via increasing the AMP:ATP ratio and activating LKB1, subsequently activating AMPK, which stimulates DAF-16 to induce downstream effects through a DAF-16 translocation independent manner.
