Arntl | aryl hydrocarbon receptor nuclear translocator-like | Arntl knockout mice display symptoms of premature aging including a shorter lifespan, sarcopenia, cataracts, less subcutaneous fat, and organ shrinkage [16847346]. | House mouse |
Atm | Ataxia telangiectasia mutated homolog (human) | Atm-deficient mice are viable, retarded in growth, infertile (male produce no mature sperm and female no gametes), display neurological dysfunction, and exhibit severe defects in T cell maturation while going on to develop thymomas [8917548; 8689683]. The majority of mutant mice rapidly develop thymic lymphomas and die before 4 months of age [8843194].
Cells of Atm(-/-) mice exhibit slow growth also in culture and premature senescence, telomeres are extensively shortened in multiple tissues [8689683].
Mice mutant for Atm and Terc display progressive multi-organ system compromise and features of accelerated aging [12540856]. | House mouse |
dcp-66 | Deacetylase Complex Protein 66 | dcp-66 RNAi shortens the mean lifespan by 29% and suppresses lifespan extension by isp-1 mutation, but does not significantly affect lifespan extension neither by eat-2 nor daf-2 mutation [22829775]. | Nematode |
EXO1 | exonuclease 1 | The rs1776180 C allele in the promoter of EXO1 is significantly enriched in female Germans centenarians and this can be replicated in 445 female French centenarians. The C allele leads to the loss of binding site for the basic helix-loop-helix transcription factor E47, resulting in higher EXO1 expression [19698732].EXO1 was found to be associated with longevity [19698732]. EXO1 was not found to be associated with longevity [23770741]. | Human |
GCN4 | Transcriptional activator of amino acid biosynthetic genes in response to amino acid starvation; expression is tightly regulated at both the transcriptional and translational levels | Deletion of GCN4 increases the replicative lifespan by 10% in the alpha strain [19030232].
GCN4 deletion decreases the lifespan in the alpha and a strain [20657825].
The chronological lifespan of GCN4 deletion is strongly decreased in the a strain [20421943]. | Budding yeast |
SOD1 | SuperOxide Dismutase 1 | The overexpression of Sods, mitochondrial Sod2 and cytosolic CuZnSod (Sod1), in combination delays the age-dependent reversible inactivation of mitochondrial aconitase, a superoxide-sensitive enzyme, and extends chronological lifespan by 30% [12586694]. Deletion of SOD1 decreases replicative lifespan by 40% [17460215]. Overexpression of SOD1 with CCS1 levuates the level of Cn, Zn-Sod activity and increased chronological lifespan. However overexpression of SOD1 without high cooper or simultonous overexpression of CCS1 shortened both chronological and replicative lifespan [15659212]. Overexpression of SOD1 has no effect on replicative lifespan [10224252]. Deletion of SOD1 shortens replicative lifespan by approximately 40%. The magnitude of the decrease in lifespan does not appear to dependent on oxygen concentration in the atmosphere [12020810]. Deletion of SOD1 shortens replicative lifespan [10547026]. Deletion of SOD1 shortens replicative as well as chronological lifespan [10222047].
Cells with a deletion of SOD1 exhibit a profound defect in entry into and survival during stationary phase (i.e. chronological lifespan) in the W303-B strain [8647826; 10222047], which is partially suppressed by expression of human Bcl-2 [9199172].
Hypersensitivity to oxygene and significantly decreased replicative lifespan of SOD1 deletion can be ameliorated by exogenous ascorbate. If acorbate's negative effects of auto-oxidation are prevented by exchange of medium, ascorbate prolongs mean and maximum replicative lifespan in the atmosphere of air and pure oxygene [15621721].
SOD1 deletion causes sensitivity to hyperoxia as well as methionine and lysine auxotrohies [9199172].

WRN | Werner syndrome, RecQ helicase-like | Mutation in WRN causes Werner Syndrome which characteristics includes prematurely aged facies, scleroderma-like skin changes, cataracts, arteriosclerosis, subcutaneous calcification, and diabetes mellitus [McKusick et al. 1963; 5327241]. Inheritance is autosomal recessive and malignancy is frequent. THe frequency is 3 per million individuals in Japan [7460386].
Cells from a Werner heterozygote exit the cell cycle at a faster rate than do normal cells [8265666]. Loss of WRN promoter aberrant mitotic recombination [11316787].
The single nucleotide polymorphism rs1800392 in WRN has been associated with exceptional longevity in a plethora of genetic signatures [22279548]. WRN was found to be associated with longevity [10069711; 20855428; 20855428; 20855428 ;17903295; 22406557; 16405962; 16405962; 16405962; 20855428; 20855428; 20855428; 22279548]. WRN was found to be associated with longevity [24244950]. | Human |
