Genetic mutants with age-1, oga-1 alterations

    Names of genes are ordered alphabetically. For the order of interventions, please see the specific paper.
  • Temperature °C


  • Diet

    NGM; OP50

  • Lifespan (days)


  • Lifespan change (compared to wild type)


  • Phenotype

    The adult lifespan extension associated with the oga-1(ok1207) mutant is not synergistic or additive with mutations of the long-lived insulin signaling pathway kinase age-1.

  • Lifespan comparisons

    Double mutant age-1(hx546);oga-1(ok1207) has a lifespan of 24.7 days, while single mutant age-1(hx546) has a lifespan of 25.6 days, single mutant oga-1(ok1207) has a lifespan of 20.9 days and wild type has a lifespan of 15.9 days.

Phosphatidylinositol 3-kinase age-1;hypothetical protein

Locus: CELE_B0334.8

Wormbase description: age-1 encodes the C. elegans ortholog of the phosphoinositide 3-kinase (PI3K) p110 catalytic subunit; AGE-1, supplied maternally and embryonically, is a central component of the C. elegans insulin-like signaling pathway, lying downstream of the DAF-2/insulin receptor and upstream of both the PDK-1 and AKT-1/AKT-2 kinases and the DAF-16 forkhead type transcription factor, whose negative regulation is the key output of the insulin signaling pathway; in accordance with its role in insulin signaling, AGE-1 activity is required for regulation of metabolism, life span, dauer formation, stress resistance, salt chemotaxis learning, fertility, and embryonic development; although the age-1 expression pattern has not yet been reported, ectopic expression studies indicate that pan-neuronal age-1 expression is sufficient to rescue life-span defects, while neuronal, intestinal, or muscle expression can partially rescue dauer formation, and neuronal or muscle expression can rescue metabolic defects.

O-GlcNAc selective N-Acetyl-beta-D-glucosaminidase (O-GlcNAcase)

Locus: CELE_T20B5.3

Wormbase description: oga-1 encodes an ortholog of mammalian O-linked N-acetylglucosamine (O-GlcNAc)-selective N-acetyl-beta-D-glucosaminidase (O-GlcNAcase); a polymorphism of OGA-1's human ortholog MGEA5 is associated with type 2 diabetes, and OGA-1 appears to be required for fine-tuning of insulin signalling; oga-1(ok1207) mutants are viable and fertile but accumulate O-GlcNAc on nuclear pores and other proteins, while showing S/T-phosphorylation of proteins, increased GSK-3beta activity, excess glycogen and trehalose, and decreased lipid storage; oga-1(ok1207) mutations enhance the Daf-c phenotype of daf-2(e1370ts) alleles even under conditions where oga-1(ok1207) alone diminishes dauer formation.
