NADH-quinone oxidoreductase 1 (NQO1) modulates cellular NAD(+)/NADH ratio which has been associated with the aging and anti-aging mechanisms of calorie restriction (CR). Here, we demonstrate that the facilitation of NQO1 activity by feeding β-lapachone (βL), an exogenous NQO1 co-substrate, prevented age-dependent decline of motor and cognitive function in aged mice. βL-fed mice did not alter their food-intake or locomotor activity but did increase their energy expenditure as measured by oxygen consumption and heat generation...

Coenzyme Q10 supplementation increases life-span of rats fed on a diet enriched with polyunsaturated fatty acids (Quiles, J.L., Ochoa, J.J., Huertas, J.R., Mataix, J., 2004b. Coenzyme Q supplementation protects from age-related DNA double-strand breaks and increased lifespan in rats fed on a PUFA-rich diet. Exp. Gerontol. 39, 189-194). Our study was set as a first attempt to establish a mechanistic link between life span extension and CoQ10 supplementation. When rats were fed on a PUFAn-6 plus CoQ10 diet, levels of CoQ10 were increased in plasma membrane at every time point compared to control rats fed on a PUFAn-6-alone diet...
