Intermediary metabolism.
Caenorhabditis elegans has orthologs for most of the key enzymes involved in eukaryotic intermediary metabolism, suggesting that the major metabolic pathways are probably present in this species. WeExpand

Life extension via dietary restriction is independent of the Ins/IGF-1 signalling pathway in Caenorhabditis elegans
Dietary restriction (DR) increases life span in a wide variety of animals. In Caenorhabditis elegans both reduced bacterial concentration (BDR) and culture on non-bacterial, semi-defined, axenic foodExpand

Axenic growth up-regulates mass-specific metabolic rate, stress resistance, and extends life span in Caenorhabditis elegans
Culture in axenic medium causes two-fold increases in the length of development and adult life span in Caenorhabditis elegans. We asked whether axenic medium imposes dietary restriction (ADR), andExpand

Testing the rate-of-living/oxidative damage theory of aging in the nematode model Caenorhabditis elegans
The integration of the rate-of-living and oxidative damage theory of aging predicts that lifespan extension is linked to low energy metabolism, low ROS production rates, low molecular damage and aExpand

Reduced Insulin/Insulin-like Growth Factor-1 Signaling and Dietary Restriction Inhibit Translation but Preserve Muscle Mass in Caenorhabditis elegans *
Reduced signaling through the C. elegans insulin/insulin-like growth factor-1-like tyrosine kinase receptor daf-2 and dietary restriction via bacterial dilution are two well-characterizedExpand

Metformin promotes lifespan through mitohormesis via the peroxiredoxin PRDX-2
Significance Recently it has been suggested that metformin, the most commonly used antidiabetic drug, might also possess general health-promoting properties. Elucidating metformin’s mode of actionExpand

LC–MS Proteomics Analysis of the Insulin/IGF-1-Deficient Caenorhabditis elegans daf-2(e1370) Mutant Reveals Extensive Restructuring of Intermediary Metabolism
The insulin/IGF-1 receptor is a major known determinant of dauer formation, stress resistance, longevity, and metabolism in Caenorhabditis elegans. In the past, whole-genome transcript profiling wasExpand

Iron-Starvation-Induced Mitophagy Mediates Lifespan Extension upon Mitochondrial Stress in C. elegans
Frataxin is a nuclear-encoded mitochondrial protein involved in the biogenesis of Fe-S-cluster-containing proteins and consequently in the functionality of the mitochondrial respiratory chain.Expand

Assaying metabolic activity in ageing Caenorhabditis elegans
Accurate measures of physiological and metabolic condition could provide more insight into how longevity genes and signalling pathways affect global metabolic activity and life span. The presentExpand

Disruption of insulin signalling preserves bioenergetic competence of mitochondria in ageing Caenorhabditis elegans
BackgroundThe gene daf-2 encodes the single insulin/insulin growth factor-1-like receptor of Caenorhabditis elegans. The reduction-of-function allele e1370 induces several metabolic alterations andExpand
