(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) 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...

(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) Background: We here show that inhibitors of mitochondrial complex I promote physical activity, stress resistance as well as lifespan of Caenorhabditis elegans despite normal food uptake, i.e. in the absence of DR. Dietary restriction (DR) extends lifespan and promotes metabolic health in evolutionary distinct species.

(Submitter supplied) FoxO transcription factors promote longevity across taxa. How they do so is poorly understood. In the nematode Caenorhabditis elegans, the A- and F-isoforms of the FoxO transcription factor DAF-16 extend life span in the context of reduced DAF-2 insulin-like growth factor receptor (IGFR) signaling. To elucidate the mechanistic basis for DAF-16/FoxO-dependent life span extension, we performed an integrative analysis of isoform-specific daf-16/FoxO mutants. more...

(Submitter supplied) We have shown that worms that possess mutations in two electron transport chain subunits live longer due to mtROS signalling. Wild type worms can also live longer by treatment with the pro-oxidant paraquat. Paraquat treatment is not additive to the mutations in the ETC subunits. We aimed to determine the underlying changes in gene expression that were common to both paraquat treatment and the two mutations. more...

(Submitter supplied) Background: C. elegans fed with a chemical inhibitor of glucose, namely 2-deoxy-D-glucose (DOG), exhibit considerably extended life span. DOG, in contradiction to D-glucose, cannot be metabolized in the glycolytic pathway. This results in the fact that less glucose is available for ATP production, and thus makes DOG-feeding of the roundworms equivalent to glucose restriction.

(Submitter supplied) We demonstrate that transcriptomic profiling of the NER mutant ercc-1 offers better understanding of the complex phenotypes of ercc-1 deficiency in C. elegans, as it does in mammalian models. There is a transcriptomic shift in ercc-1 mutants that suggests a stochastic impairment of growth and development, with a shift towards a higher proportion of males in the population. Extensive phenotypic analyses confirm that NER deficiency in C. more...

(Submitter supplied) Vaccinia virus-related kinase (VRK) is an evolutionarily conserved nuclear protein kinase. VRK-1, the single Caenorhabditis elegans VRK ortholog, functions in cell division and germline proliferation. However, the role of VRK-1 in post-mitotic cells and adult lifespan remain unknown. Here, we show that VRK-1 increases organismal longevity by activating the cellular energy sensor, AMP-activated protein kinase (AMPK), via direct phosphorylation. more...
