It was recently reported that the plant polyphenol resveratrol, found, e.g., in grape berry skins, extended lifespan in the fruit fly Drosophila melanogaster and the nematode worm Caenorhabditis elegans. This lifespan extension was dependent on an NAD(+)-dependent histone deacetylase, Sir2 in Drosophila and SIR-2.1 in C. elegans. The extension of lifespan appeared to occur through a mechanism related to dietary restriction (DR), the reduction of available nutrients without causing malnutrition, an intervention that extends lifespan in diverse organisms from yeast to mammals. In Drosophila, lifespan extension by DR is associated with a reduction in fecundity. However, a slight increase in fecundity was reported upon treatment with resveratrol, suggesting a mode of action at least partially distinct from that of DR. To probe this mechanism further, we initiated a new study of the effects of resveratrol on Drosophila. We saw no significant effects on lifespan in seven independent trials. We analysed our resveratrol and found that its structure was normal, with no oxidative modifications. We therefore re-tested the effects of resveratrol in C. elegans, in both wild-type and sir-2.1 mutant worms. The results were variable, with resveratrol treatment resulting in slight increases in lifespan in some trials but not others, in both wild type and sir-2.1 mutant animals. We postulate that the effect of resveratrol upon lifespan in C. elegans could reflect induction of phase 2 drug detoxification or activation of AMP kinase.

    • "A question is thereby raised on the relationship between the antioxidant activity and the anti-aging efficacy of TCMF. Indeed, despite extensive research, lifespan studies using antioxidants have often been disappointing (Bass et al. 2007; Ran et al. 2007). Because candidate compounds are frequently selected simply by their vitro antioxidant efficacy, with the assumption that vitro is equal to vivo antioxidants and the latter will certainly extend lifespan.

    ABSTRACT: There is considerable interest in using traditional Chinese medicine formulas (TCMF) to delay aging or treat age-related diseases. Due to cost and duration, the beneficial effects of TCMF on prolongation are mainly extrapolated from vitro studies or physiological indexes. Little is known about whether TCMF are beneficial in whole level, particularly with respect to lifespan. To address this issue, we selected eight formulas with anti-oxidative activity and examined their effects on the lifespan of Caenorhabditis elegans. The results showed that seven of the eight formulas could prolong lifespan of TK22 mutant significantly and five of the eight formulas could obviously extend lifespan of N2 wild-type. To further characterize the prolongation effects, oxidative stress, thermal stress and reproduction test were assayed. We found that the formulas that extended lifespan of TK22 could also protect it from oxidative stress, without reducing the reproductive capacity. Meanwhile, the formulas that prolonged lifespan of N2 wild-type could also enhance its resistance against thermal stress, with damaging the reproductive fitness. These observations indicate that TCMF used in our experiment could be potential therapeutics for anti-aging.

    • "We have recently demonstrated that SIRT1 activation induced by resveratrol modulates the mitogen-activated protein kinase pathway [68]. Small molecules such as resveratrol are of great interest because they increase life-span in many species in a sirtuin-dependent manner [69] [70]. "

    ABSTRACT: Oxidative stress has a prominent role in lifespan regulation of the living organisms. One of the endogenous free radical scavenger systems is associated with GSH, the most abundant nonprotein thiol in mammalian cells, acting as a major reducing agent and antioxidant defence by maintaining a tight control of the redox status. We have recently designed a series of novel S-acyl-GSH derivatives capable to prevent amyloid oxidative stress and cholinergic dysfunction in Alzheimer disease models, upon the increase of GSH intake. In this study we show that the longevity of wild-type N2 Caenorhabditis elegans strain was significantly enhanced by dietary supplementation with linolenoyl-SG (lin-SG) thioester with respect to ethyl ester of GSH, linolenic acid or vitamin E. RNA interference analysis and activity inhibition assay indicate that lifespan extension was mediated by the upregulation of SIR-2.1, a NAD-dependent histone deacetylase ortholog of mammalian SIRT1. In particular, lin-SG-mediated overexpression of sir-2.1 appears to be related to the DAF-16 (FoxO) pathway. Moreover, lin-SG derivative protects N2 worms from the paralysis and oxidative stress induced by Aβ/H2O2 exposure. Overall, our findings put forward lin-SG thioester as an antioxidant supplement triggering sirtuin upregulation, thus opening new future perspectives for healthy aging or delayed onset of oxidative-related diseases.

    • "Resveratrol might not activate sirtuins in vivo (Kaeberlein et al., 2005; Pacholec et al., 2010), and sirtuins might not be involved in the extension of lifespan (Burnett et al., 2011). Some researchers have reported that resveratrol increased life span modestly, but the effect was either not or only marginally significant in Caenorhabditis elegans, Drosophila melanogaster, and mice (Bass et al., 2007; Miller et al., 2011), despite the fact that gene expression patterns of animals treated with resveratrol had some degree of similarity to those with low diet (Barger et al., 2008; Pearson et al., 2008). In addition, survival curves of animals treated with resveratrol are sometimes different from those with dietary restriction (Valenzano et al., 2006; Chandrashekara and Shakarad, 2012). "

    ABSTRACT: Longevity is a highly variable life history trait and its variation is attributable to both genetic and environmental factors. Exploring well-known environmental factors in a new model system is a useful approach to explore taxonomic variation in plasticity of longevity. We examined responsiveness of the Daphnia pulex clone TCO to potentially related interventions that have been reported to extend lifespan: resveratrol and dietary restriction. First, we examined effects of resveratrol on lifespan and fecundity in TCO which were grown at moderate (12K cells Ankistrodesmus falcatus mL(-1) ) and high (20K cells A. falcatus mL(-1) ) food levels. We found no evidence for lifespan extension by resveratrol, but found a reduction of lifetime fecundity. The effect of resveratrol on fecundity was more pronounced early in life. We then conducted an additional life table to test the effect of dietary restriction on TCO. Surprisingly, reduced food level did not extend the lifespan of TCO, which contrasts with previous studies in D. pulex. Our results suggest that variation in the response to dietary restriction might be more common than previously thought. If resveratrol activates genes involved in the response to dietary restriction, genetic polymorphisms in dietary restriction will influence responses to resveratrol. Thus, this experiment suggests that careful re-examination of resveratrol effects using diverse genotypes is required. J. Exp. Zool. 9999A: 1-9, 2013. © 2013 Wiley Periodicals, Inc.
