| mir-34 upregulation | mir-34 upregulation extends median lifespan and mitigated neurodegeneration induced by polyglutamine. | Fly | — | — | — |

| Jafrac1 overexpression | Neuronal overexpression of Jafrac1 significantly increases both mean and maximum lifespan, while neuronal knockdown as well as loss of function mutation, causes a reduction in lifespan by 30%. The mean lifespan is 26% and 29% higher in females and males, respectively. The maximum lifespan is increased by 22% and 26% in females and males, respectively [19720829].
There is a consistent and significant lifespan extension (15% mean lifespan increase) in both males and females when Jafrac1 is overexpressed in somatic cells. Jafrac1 overexpression using the weaker 5961FS driver moderately but significantly extends lifespan [20976250]. | Fly | +15 to +29 | +22 to +26 | — |

| DATS treatment | Treatment with 5-10 μM DATS increases lifespan even when treatment is started during young adulthood. DATS increases the lifespan of daf-2 and daf-16 mutants, but not that of eat-2 mutants.
DATS treatment leads to the induction of the skn-1 target gene gst-4 and this induction is dependent on skn-1. DATS effect on lifespan is dependent on skn-1 activity in both intestine and ASI neurons [21296648]. | Fly | — | — | — |
| THC treatment | In male mice supplementation with tetrahydrocurcumin beginning at the age of 13 month increases the mean lifespan by an average of 84 days, i.e. an increase of 11.7% [17516143]. | Mouse | +11.7 | — | — |
| THC treatment | Tetrahydocurcumin extends the lifespan and reduces oxidative stress in male and female fruit flies. THC extends lifespan of Drosophila and inhibits the oxidative stress response by regulating *FOXO* and *Sir2* [22156377]. | Fly | — | — | — |
| tert knockout | First-generation tert(-/-) zebrafish die prematurely with shorter telomeres. tert(-/-) fish develop degenerative phenotypes, including premature infertility, gastrointestinal atrophy, and sarcopenia. tert(-/-) mutants have impaired cell proliferation, accumulation of DNA damage markers, and a p53 response leading to early apoptosis, followed by accumulation of senescence cells. Apoptosis is primarily observed in the proliferative niche and germ cells. Cell proliferation, but not apoptosis, is rescued in tp53(-/-)tert(-/-) mutants, underscoring p53 as mediator of telomerase deficiency and consequent telomere instability [http://denigma.de/url/3p]. | Zebra | — | — | — |
| Drd4 knockout | 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]. | Mouse | -7 to -9.7 | — | — |
| Fxn disruption | Disruption results in reduced lifespan, increased oxidative stress, impaired respiration, and the development of hepatic tumors [16278235]. | — | — | — | — |
| Foxm1 overexpression | Increased hepatocyte expression in 12-month-old (aged) transgenic mice of Foxm1b alone is sufficient to restore hepatocyte proliferation to levels found in 2-month-old (young) regenerating liver [14647066]. | Mouse | — | — | — |
| Foxm1 deletion | Deletion of Foxm1 causes age-related deterioration in liver regeneration [14647066]. | Mouse | — | — | — |
| Fgf23 knockout | 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]. | Mouse | — | — | — |

| Efemp1 knockout | 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]. | Mouse | — | +20 | +30 |
| Cdkn1a knockout | Deletion of Cdkna1 (alias p21) prolongs the lifespan of telomerase-deficient mice with dysfunctional telomeres and improves the repopulation capacity and self-renewal of hematopoietic stem cells [17143283].
The p21(-/-) strains like the Cdkn1a(tmi/Tyj) exhibits enormous regenerative capacities as it closes ear holes similar to MRL mice [20231440; 21722344]. | Mouse | — | — | — |
| Cav1 knockout | Knockout mice are viable and fertile but exhibit an approximately 50% reduction in lifespan probably due to a combination of pulmonary fibrosis, pulmonary hypertension, and cardiac hypertrophy [14690422]. | Mouse | -50 | — | — |
| Casp-2 deficiency | Loss of caspase-2 resulted in a shortened (10%) maximum lifespan and in enhanced aging-related traits such as impaired hair growth, increased bone loss, and reduced body fat content [17188333]. | Mouse | — | — | -10 |
| Bub3 and Rae1 haploinsuficiency | Haploinsufficiency of Bub3 and Rae1, but not haploinsufficiency of either gene by itself, reduces lifespan by 12% and appears to accelerate aging [16476774]. | Mouse | -12 | — | — |
| Brca1 deletion | Deletion of Brca1 causes senescence in mutant embryos and cultured cells and tumorigenesis and signs of premature aging in adults [12533509]. Brca1 heterozygous seem to have shortened lifespan with 70% of tumor incidence. Lymphoma, but not ovarian and mammary gland tumors, occurs commonly in these animals. After a whole-body exposure to ionizing radiation, Brca1 heterozygous mice have a 3-5-fold higher incidence to ovarian tumors, but not lymphoma, when compared with Brca1(+/+) mice [17420720]. | Mouse | — | — | — |
| Bax knockout | Inactivation of proapoptotic Bax extends fertile potential and minimized age-related health problems, including bone and muscle loss, excess fat deposition, alopecia, cataracts, deafness, increased anxiety, and selective attention deficit. Bax deficiency does not lead to an increase in tumor incidence. Despite the apparently increased quality of life of aging females lacing Bax, there is no significant differences in overall lifespan [17360389]. | Mouse | — | — | — |
| Atr knockout | Deletion of Atr in young adults eliminates 80-90% of proliferating cells and results in several age-related phenotypes accompanied by a depletion of stem and progenitor cells and exhaustion of tissue renewal and homeostatic capacity [18371340].
Atr mutant mice (so called Seckle mice) exhibit high levels of replicative stress during embryogenesis, when proliferation is widespread, but this is reduced to marginal amounts in postnatal life. In spite of this decrease, adult Seckel mice display accelerated aging, which is further aggravated in the absence of p53. Seckel mice die in less than half a year, exhibit pancytopenia, cachexia and signs of premature aging, including hair graying, kyphosis, osteoporosis, accumulation of fat in the bone marrow, decreased density of hair follicles and thinner epidermis [19620979]. | Mouse | — | — | — |
| Atm knockout | 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]. | Mouse | — | — | — |
| 2-MEA treatment | Addition of 1% by weight 2-MEA to the diet of male LAF mice, started shortly after weaning, increases average lifespan by approximately 30%, but does not extend maximum lifespan [5723482; 11795501].
Addition of 2-MEA to the maternal diet of female mice increases the lifespan of male and female offspring by 15 and 8%, respectively [Harman & Eddy, 1979; 11795501].
Addition of 2-MEA of an antioxidant mixture containing ethoxyquin and 2-MEA to the diet of dietary restricted mice shortens lifespan approximately 20% [2394907]. | Mouse | +30 | — | — |
