| Insr | Insulin receptor | Deletion of Insr specifically in adipose tissue results in a 15-18% increase in mean, median and maximum lifespan. Fat-specific insulin-receptor knockout (FIRKO) reduces fat mass and protects against age-related obesity and its subsequent metabolic abnormality, without an decrease in food intake. Both male and female FIRKO mice have an increase in mean lifespan of around 134 days (18%), with parallel increases in median and maximum lifespan. FIRKO mice consume the same amount of food on per animal basis as control littermates, but have 15-25% lower body-mass and 50-70% reduced fat mass [12543978]. Disruption of Insr in all tissues reults in neonatal lethality [8612577]. | House mouse |
| Xrcc5 | X-ray repair complementing defective repair in Chinese hamster cells 5 | Deletion results in signs of premature ageing such as osteopenia, atrophic skin, hepatocellular degeneration, and age specific mortality. | House mouse |
| Fxn | frataxin | Disruption results in reduced lifespan, increased oxidative stress, impaired respiration, and the development of hepatic tumors [16278235]. | House mouse |
| Drd4 | Dopamine D4 Receptor | Drd4 knockout mice, when compared with wild-type and heterozygous mice, display a 7 - 9.7% decrease in lifespan, reduced spontaneous locomotor activity, and no lifespan increase when reared in an enriched environment [23283341]. | House mouse |
| Efemp1 | Epidermal growth factor-containing fibulin-like extracellular matrix protein 1 | Efemp1 knockout mice exhibited an early onset of aging-associated phenotypes including a 20% shorted median lifespan and 30% shorter maximum lifespan, decreased body mass, lordokyphosis, reduced hair growth, and atrophy [17872905]. | House mouse |
| Ercc4 | Excision repair cross-complementing rodent repair deficiency, complementation group 4 | ERCC4-ERCC1-deficient mice exhibit signs of premature aging [17183314]. | House mouse |
| miR-214 | microRNA 214 | Expression increases with age in mouse liver. The miRNA downregulates detoxification and regeneration genes, which may contribute to aging [18561983]. | House mouse |
| Mir669c | microRNA 669c | Expression increases with age in mouse liver. The miRNA downregulates detoxification and regeneration genes, which may contribute to aging [18561983]. | House mouse |
| Fgf23 | Fibroblast growth factor 23 | Fgf23 knockouts have a short lifespan and display premature aging-like symptoms including kyphosis, muscle wasting, osteopenia, emphysema, uncoordinated movement, atherosclerosis, and atrophy of the intestinal villi, skin, thymus, and spleen [16436465].
Lack of Fgf23 activities results in extensive premature aging-like features and early mortality of Fgf-23(-/-) mice, while restoring the systemic effects of FGF-23 significantly ameliorates these phenotypes, with the resultant effect being improved growth, restored fertility, and significantly prolonged survival of double mutants [18729070]. | House mouse |
| Gdf11 | growth differentiation factor 11 | GDF11 is a circulating factor in young mice that declines with age.
Treatment of old mice to restore GDF11 to youthful levels recapitulated the of young-old parabiosis and reverses age-related hypertrophy. | House mouse |
| Pappa | Pregnancy-associated plasma protein A | Genetic deletion of PAPPA extended mean and maximum lifespan by 30-40% and reduced cancer incidence with no reduction in food intake or secondary endocrine abnormalities. | House mouse |
| Ghr | Growth hormone receptor | Ghr knockouts (the so called Laron mice) are dwarfs with significantly extended lifespan by 40-50% [12933651]. Ghr-/- mice are significantly longer lived as Ghr+/+ or Ghr+/- mice (by 40-50%) in both females and males [10875265; 19370397]. 30% DR fails to affect overall survival, average or median long-lifespan of Growth hormone receptor knockout (GHRKO) mice and increased maximal lifespan only in females. Insulin sensitivity in GHRKO mutants is greater than in wild-type and is not further increased by DR [16682650]. Intermittent fasting also fails to extend the long lifespan of GHRKO mice [19747233]. Lifespan of mice with a deletion in the Ghr gene live almost 5 years [21123740]. In C57BL/6J this mutation increases life expectancy by 16 to 26% depending on gender [12933651] and in mice of mixed genetic background the increases amounted to 36-55% [9371826]. Serum levels of GH are elevated in mutant mice [9371826] and mutants are smaller than wild-type. IGF-1 and IGFBP-3 levels are also reduced in Ghr mutant mice [10875265]. The age-associated decline in memory retention is delayed in Ghr mutants [11336996]. Overexpression of a growth hormone antagonist (a mutated growth hormone that competes with the endogenous one) has no effect on lifespan [12933651]. | House mouse |
| Gsta4 | glutathione S-transferase, alpha 4 | Gsta4 null mice, had impaired 4-hydroxynonenal detoxification, but extended average lifespan. | House mouse |
| Rae1 | RAE1 RNA export 1 homolog (S. pombe) | Haploinsufficiency of Bub3 and Rae1, but not haploinsufficiency of either gene by itself, reduces lifespan by 12% and appears to accelerate ageing. | House mouse |
| Bub3 | budding uninhibited by benzimidazoles 3 homolog (S. cerevisiae) | Haploinsufficiency of Bub3 and Rae1, but not haploinsufficiency of either gene by itself, reduces lifespan by 12% and appears to accelerate aging [16476774]. | House mouse |
| Gpx4 | Glutathione peroxidase 4 | Heterozygous knockouts have a 7% increase in median lifespan. | House mouse |
| Trp63 | Transformation related protein 63 | Heterozygous Trp632 mutant mice have a shortened lifespan (by 21.5%) and display features of accelerated aging [16107615].
The decreased longevity in Trp63(+/-) mice is almost identical to that of Trp53(+/m) mice in which enhanced Trp53 activity provides resistance to spontaneous tumors while simultaneously accelerating aging [16107615]. Trp63(+/-) are not susceptible to spontaneous tumors [16107615]. | House mouse |
| Shc1 | SHC (Src homology 2 domain containing) transforming protein 1 | Heterozyogus and homozygous Shc1 knockout mice have an 7% and 28% increase in mean lifespan, respectively [10580504].
p66shc-/- cells are more resistant to apoptosis induced by hydrogen peroxide and UV light. p66shc-/- mice aremore restante to oxidative stress induced by paraquat [10580504]. | House mouse |
| Nudt1 | nudix (nucleoside diphosphate linked moiety X)-type motif 1 | hMTH1-Tg mice express high levels of the hMTH1 hydrolase that degrades 8-oxoGTP and 8-oxoGTP and excludess 8-oxoguanine from both DNA and RNA.
hMTH1-overexpresing mice have significantly lower steady-state levels of 8-oxoguanine in both nuclear and mitochondrial DNA of several organs, including the brain. hMTH1 overexpression prevents the age-dependent accumulation of DNA 8-oxoguanine that occurs in the wild-type mice. These lower levels of oxidized guanines are associated with increased longevity and hMTH1-Tg animals live significantly longer than their wild-type littermates [23648059].

| HNRNPD | eterogeneous nuclear ribonucleoprotein D (AU-rich element RNA binding protein 1, 37kDa) | HNRNPD controls inflammation by turning off the inflammatory response to stop the onset of septic shock. Cessation of inflammatory cytokine respisne is mediated partly through cytokine mRNA degradation facilitated by RNA-binding proteins, including HNRNPD. HNRNPD deletion leads to accelerated aging as evidenced by strinking telomere erosion, markedly increased DNA damage repsosne at telomere ends, pronounced cellular senescence and rapid premature aging that increases with successive generations. HNRNPD which is a family of four related genes also maintains the integrity of chromosomes by activating telomerase, because HNRNPD strongly activates the transcription promoter for Tert [Pont et al., 2012]. | House mouse |
| Ghrhr | Growth hormone releasing hormone receptor | Homozygosity for the Ghrhr(lit) knockout mutation (called little mouse) lowers plasma growth hormone levels, impairs growth and increases lonegevity about 20% [11371619]. Lit homozygous animals are smaller than normal mice [1270792] and their pituitary is defective in growth hormone and prolactin [978118]. | House mouse |
| Top3b | Topoisomerase (DNA) III beta | Homozygous disruption of Top3b results in a normal development but a shorter lifespan (by approximately 70%) accompanied by lesions in multiple organs in C57BL/6 [11331780].
Yeast Top3 physically interacts with Sgs1 [7969174]. Human TOP3A interacts with BLM [10734115; 10728666] and both TOP3A and TOP3B interact with RECQ5 [10710432]. | House mouse |
| Lmna | lamin A | Homozygous mice display signs of premature ageing, including a marked reduction in growth rate and death by 4 weeks of age. | House mouse |
| Igf1r | Insulin-like growth factor 1 receptor | Homozygous null mutation of Igf1r is lethal at birth [8402901]. Mice heterozygous for IGF1R live 26% longer. Female Igf1r(+/-) mice have 33% longer mean lifespan, whereas male mice exhibit an increase in mean lifespan of 16% (not statistically significant). Long-lived Igf1r+/- mice do not develop dwarfism, have normal energy metabolism, food and water intake, unaffected nutrient uptake, physical activity, glucose regulation, serum insulin and glucose, fertility and reproduction [12483226]. Heterozygous Igf1r mutants are more resistant to paraquat and mouse embryonic fibroblasts derived from them are more resistant to hydrogen peroxide [8402901]. | House mouse |
| Prdx1 | Peroxiredoxin 1 | Homozygous Prdx1 knockout mice have a lifespan significant shorter than +/+ and +/- littermates and develop severe haemolytic anaemia and several malignant cancers (starting at about 9 months of age) [12891360] | House mouse |
