| Resveratrol supplementation | A maximum dose of resveratrol increases the median lifespan by 56% [16461283]. | Fish | — | +56 | — |
| LA treatment | LA confers a memory effect, by fixing the lifespan of previous feeding regimen. When animals are switched early in life (12 months) from DR to AL and supplemented with α-lipoic acid the DR typical lifespan extension is maintained, but switching early from AL supplemented with α-lipoic acid to DR blocks the lifespan extending effect [18486188].
LA exhibits the ability to compensate for age-related, long-term memory deficits in old rats [8309958].

| Metformin treatment | In rats metformine treatment reduces body weight significantly (despite similar food intake) but fails to significantly extend the lifespan at any quantile (25th, 50th, 75th, or 90th), overall or maximum lifespan (p > 0.05) [20304770]. | Rat | — | — | — |
| C60-olive oil treatment | Oral administration of C60 dissolved in olive oil (0.8 mg/ml) at reiterated doses (1.7 mg/kg of body weight) for just about 7 months to rats not only does not entail chronic toxicity but it almost doubles the lifespan. The effects on lifespan is mainly due to the attenuation of age-associated increases in oxidative stress. Dissolved C60 is absorbed by the gastro-intestinal tract and eliminated in a few tens of hours [22498298].
C60-olive oil can increase the mean, median and maximum lifespan by 114, 91 and 74%. C60-olive oil extends the lifespan of animals with a probability of 0.999 and 0.995 with respect to water and olive oil treatments, respectively [22498298].
The GSSG/GSH ratio of animals treated by C60-oil is significantly less (about twice as less) as compared to controls [22498298].

| Olive oil treatment | Oral treatment with Olive oil (at the age of 10 month for 7 months) increases mean, median and maximum lifespan by 41, 18 and 53%, respectively. Olive oil extends the lifespan with a probability of 0.99 [22498298]. | Rat | +41.4 | +18.2 | +52.6 |
| Npy overexpression | Overexpression of Npy under the control of its own promoter results in increased mean and maximum lifespan. However the observed lifespan extension is relatively small (p = 0.0059 by Wilcoxin test and p = 0.05 by t-test; n = 20) [12668588].
The blood pressure of Npy transgenic rats was significantly lower as compared with nontransgenic siblings. Food intake and weight were not significantly different compared to controls [12668588]. | Rat | — | — | — |
| Homozygous Gh1 anti-sense transgene | Animals carrying two copies of a Gh1 anti-sense transgene (tg/tg) have a slighlty shorter lifespan (by 5-10%) compared to -/- animals. tg/tg animals are dwarfs and exhibit reduced levels of serum IGF1 [12057928]. | Rat | -5 to -10 | — | — |
| Heterozygous Gh1 anti-sense transgene | Animals carrying a single copy of an anti-sense Gh1 transgene (tg/-) live on average 7-10% longer. tg/- animals are dwarfs and exhibit reduced levels of serum IGF1 [12057928]. | Rat | +7 to +10 | — | — |
| Nudt1 Overexpression | 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]. | Mouse | — | — | — |
| 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 | — | — |
| 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 | — | — |
| 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 | — | — |
| Arhgap1 knockout | Most Ahrgap1 knockout mice are weak and die during the neonatal period. Animals that survived have a shorter lifespan (median lifespan is 12 months) and show premature aging-like phenotypes, including a reduction in body mass, a loss of subdermal adipose tissue, lordokyphosis, and osteoporosis [17227869]. | Mouse | — | — | — |
