(Submitter supplied) Hormesis occurs when a low level stress elicits adaptive beneficial responses that protect against subsequent exposure to severe stress. Recent findings suggest that mild oxidative and thermal stress can extend lifespan by hormetic mechanisms. Here we show that the botanical pesticide plumbagin, while toxic to C. elegans nematodes at high doses, extends lifespan at low doses. Because plumbagin is a naphthoquinone that generates free radicals in vivo, we investigated whether it extends lifespan by activating an adaptive cellular stress response pathway. more...

(Submitter supplied) One of the most important issues in the study of aging is to discover compounds with longevity-promoting activity and to unravel their underlying mechanisms. Queen honey bees are continuously fed royal jelly (RJ), and they live more than 10 times longer than hive workers, derived from the same diploid genome, which are fed it only for a short period of time during their larval stages. Therefore, RJ is likely to contain longevity-promoting agents for queens. more...

(Submitter supplied) Background: Arsenite is one of the most toxic chemical substances known and is assumed to exert detrimental effects on viability even at lowest concentrations. By contrast and unlike higher concentrations, we here find that exposure to low-dose arsenite promotes growth of cultured mammalian cells. In the nematode C. elegans, low-dose arsenite promotes resistance against thermal and chemical stressors, and extends lifespan of this metazoan, whereas higher concentrations reduce longevity. more...

(Submitter supplied) Aging is a major international concern and brings with it formidable socioeconomical and healthcare challenges. An attainable approach to improve general health in humans is using small molecules. Tomatidine, a natural compound abundant in unripe tomatoes, inhibits aging-related skeletal muscle atrophy in mice. Here we show that tomatidine extends lifespan and healthspan in the aging animal model C. more...

(Submitter supplied) We have identified through high-throughput screen a number of small molecules that promote resistance of human WI-38 cells to hydrogen peroxide. To look into potential mechanism of action for a chalcone hit, we analyzed transcriptional profile by RNA-seq for WI-38 cells treated with this molecule.

(Submitter supplied) Vitamin D is a secosteroid that has multiple regulatory roles including the regulation of bone and calcium homeostasis. Deficiency of 25-hydroxyvitamin D, the major circulating form of vitamin D, is associated with an increased risk of age-related chronic diseases including Alzheimer’s disease, Parkinson’s disease, cognitive impairment, and cancer. In this study, we utilized Caenorhabditis elegans to examine the mechanism by which vitamin D influences aging. more...

(Submitter supplied) In this work, we examined the effect of the transcription factor ATFS-1 in the long lifespan of the nuo-6 mitochondrial mutant. We also examined the effect of the hypoxia transcription factor hif-1. We sequenced both atfs-1 deletion mutants and atfs-1 gain-of-function point mutants in which the mitochondrial localization sequence of ATFS-1 is disrupted. Note that sequencing batch 2 was previously uploaded as part of GSE93724.

(Submitter supplied) We have previously reported that tyrosol (TYR), one of the main phenols in extra virgin olive oil (EVOO), promotes lifespan extension in the nematode Caenorhabditis elegans, also inducing a stronger resistance to thermal and oxidative stress in this animal model. Although the influence of several longevity-related genes in these effects has been reported by our group, we decided to perform a whole genome DNA-microarray approach in order to identify other genes and molecular pathways further involved in TYR effects on C. more...

(Submitter supplied) Hydrogen sulfide (H2S) has dramatic physiological effects on animals that are associated with improved survival in changing conditions. C. elegans grown in H2S are long-lived and thermotolerant (1). To begin to identify mechanisms by which adaptation to H2S effects fundamental physiological functions, we have defined transcriptional changes associated with the response to H2S. Using microarray analysis we observe rapid changes in the abundance of specific mRNAs. more...

(Submitter supplied) D-Glucosamine (2-amino-2-deoxy-D-glucose, C.A.S.# 3416-24-8) (GlcN) is a freely available and commonly used dietary supplement possibly promoting cartilage health in humans which also acts as an inhibitor of glycolysis. We here find that GlcN extends C. elegans lifespan by impairing glucose metabolism to activate AMP-activated protein kinase (AMPK/AAK2) leading to increased mitochondrial biogenesis. more...
