Genetic mutants with asm-1, asm-3, rrf-3 alterations

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

    20

  • Lifespan (days)

    22.7

  • Lifespan change (compared to wild type)

    30.46%

  • Phenotype

    Double inactivation of asm-3 and asm-1 further extended lifespan, with the mean lifespan 30% greater than that of the control.

  • Lifespan comparisons

    Triple mutant asm-1(RNAi);asm-3(ok1744);rrf-3(pk1426) has a lifespan of 22.7 days, while double mutant asm-3(ok1744);rrf-3(pk1426) has a lifespan of 20.1 days and wild type has a lifespan of 17.4 days.

Sphingomyelin phosphodiesterase 1


Locus: CELE_B0252.2


Wormbase description: asm-1 encodes a protein similar to human acid sphingomyelinase (ASM) or sphingomyelin phosphodiesterase; the ASM-1 protein has a putative secretory signal peptide at the N-terminus, saposin-like and proline-rich domains and putative N-linked glycosylation sites; asm-1 shows phosphodiesterase activity when expressed in COS-7 cells; while mammalian ASM is detected as both intracellular and secreted forms, asm-1 was detected exclusively in the secreted form; northern blot analysis indicates that asm-1 is expressed at higher levels in the embryo compared with other stages.

RNA-dependent RNA polymerase Family


Locus: CELE_F10B5.7


Wormbase description: rrf-3 encodes an RNA-directed RNA polymerase (RdRP) homolog that inhibits somatic RNAi, and thus promotes activity of repeated genes (e.g., multicopy transgenic arrays); the effect of RRF-3 on RNAi is opposite to that of RRF-1 (which stimulates somatic RNAi), which might arise from competition by RRF-3 with RRF-1 or EGO-1 in RNAi formation; rrf-3(allele) or rrf-3(allele2) mutants are hypersensitive to somatic RNAi, and conversely suppress the activity of an integrated rol6 (su1006) transgene.
