In conclusion, our findings present new insights into the mechanism underlying endogenous metabolite-mediated longevity. Besides α-KB, other endogenous metabolites, such as oxaloacetate72, ω-6 polyunsaturated fatty acids73, and α-ketoglutarate74, can also delay aging and extend lifespan, suggesting that the key to longevity is hidden in our body. The endogenous metabolites provide new approaches for the prevention and treatment of aging and aging-related diseases
