| Overexpression of mitochondrial targeted CAT | Overexpression of human catalase targeted to mitochondria (MCAT) extends mean and maximum lifespan by about 20% in mice. Inactivation of aconitase in heat mitochondria and mitochondrial damage is also reduced in long-lived CAT mutant mice [15879174].
The MCAT strain has a reduced severity of age-dependent arteriosclerosis and increased genomic stability, as indicated by an decrease in oxidative stress and mitochondrial deletions in heart and muscle tissues. Median and maximum lifespan in increased about 17 - 21% [16144468]. | Mouse | +20 | +17 to +21 | +17 to +21 |
| 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 | — | — | — |
| GH overexpression | Overexpression of GH is associated wtih markedly reduced lifespan and various indices of premature aging [8100276]. Transgenic mice overexpressing bovine Gh1 are bigger than controls and display early onset of pathological changes in the kidneys such glomerulosis and glomerulonephritis as well as signs of premature aging such as a shortened lifespan, increased astrogliosis, shortened reproductive lifepsan and early onset of age-related changes in cognitive function, hypothalamic neurotransmitter turnover, and plasma corticosterone levels [14583653]. | Mouse | — | — | — |
| Pten overexpression | Increasing gene dosage via homogeneous and moderate overexpression, while retaining its normal pattern of tissue expression of Pten increases mean, median and maximum lifespan in both females and males. Mean lifespan is extended by 18% (males), 11% (females) and 14% (both). Median lifespan in males, females and both increases by 12%, 16% and 12%, respectively [22405073]. Transgenic Pten mice carrying the additional genomic copies of Pten are protected from cancer and present a significant extension of lifespan that is independent of their lower cancer incidence. Pten(g) mice have an increased energy expenditure and protection from metabolic pathologies [22405073]. | Mouse | +14 | +12 | — |
| 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 | — | — | — |
| Pcmt overexpression | Overexpression of Pcmt extends lifespan by 32-39% at 29 degrees but not at 25 degrees [11742076].
The adult lifespan of animals overexpressing Pcmt is extended [18772467]. | Mouse | 0 to 39 | — | — |
| CKIepsilon mutation | A mutation in CKIepsilon called tau, if homozygous, shortens the circadian period (by 20%), increases metabolic rate (by 20%), and increases lifespan by 14-16% under conditions of constant darkness [12054192].
Male and female wild-type hamsters are heavier than homozygous mutants throughout the entire lifespan, and heterozygous mutants have intermediate weight [12054192]. | Hamster | +14 to +16 | — | — |
| Down syndrom | Individuals with Down syndrome develop the neuropathological lesions of Alzheimer disease significantly earlier than those without [3158266] and have a shorter lifespan. Down syndrome is cuased by duplication of small regions of chromosome 21 [8197171]. The major features of Down syndrome are mental retardation, characteristic facial features, congenital malformations of the heart and gastrointestinal tract, thyroid disease, and an increased incidence of leukaemia [Epstein, 1989]. Neurons cultured in vivo form individuals with Down syndrome degenerate and exhibit apoptosis [8524410]. Down syndrome neurons also display increased generation of reactive oxygen species and treatment with antioxidants can prevent degeneration. | Human | — | — | — |
| LMNA mutation | Dominant mutation in LMNA (lamin A/C) gene cause Hutchinson-Gilford progeria syndrome (HGPS) which is rare and characterized by prematurly senile appearing skin and hair, with death from coronary artery disease often by age 10 [Gilford 1904; Hutchinson 1886; OMIM]. The median age of death in HGPS individuals is 13.4 years. A C to T transition at nucleotide 1824 is associated with HGPS [Sandra-Giovannoli et al., 2003; Eriksson et al., 2003]. The 1824C-T allele appears to act in a dominant negative manner by interfering with normal splicing, resulting in production of both the normal transcript and a transcript deleted for 150 bp at the 3' end [Sandre-Giovannoli et al, 2003]. Cultured skin fibroblasts from individuals with progeria exhibit an increased fraction of hat-labile proteins [1128606].

| MORF4 overxpression | Overexpression of MORF4 reverses the immortal phenotype of immortal cell lines in complementation group B [9891081]. Cellular senescence is dominant over immortality in fused hybrids of normal and immortal human cell in culture [6879195]. Fusion of immortal cell lines with each other led to the idenetification of four complementation groups for immortality [3413074]. MORF4 rescues the immortal phenotype [9891081]. | Human | — | — | — |
| HSPA9 overexpression | Overexpression of HSPA9 (mortalin) increases the proliferation potential of normal fibroblasts [11959102]. Transfection of normal human fibroblasts with human HSPA9 (or the murine Hspa9) overexpression vectors led to an increase in the number of population doublings the cells could sustain before senescing (increase varying from 32-60%, depending on the exact construct used). Transfected cells retain a youthful morphology longer than the controls cells, and there is an dealy in appearance of senescence associated beta-galactosidase activity [10838077]. Mot-2 overexpressing cells exhibit a reduction in p53 transcriptional activation (as measured by expression from vectors containing either luciferase or beta-glactosidase driven by p53 binding sites) [10838077], which might partially or wholly explain the effects of Mot-2 on proliferative potential. HSPA9 is differentially distributed and/or translated in normal vs. transformed cells [8454632]. | Human | — | — | — |
| Pink1 overexpression | Overexpression of Pink1 and overexpression of Pink1 with alpha-synclein results in an increase in lifespan which is accompanied by an increase in healthspan (as measured by mobility) when driven by a dopaminergic cells targeting TH-Gla4 transgene [22653599]. | Fly | — | — | — |

| MAPT overexpression | Expression of wild-type human MAPT (tau) moderately shortened lifespan. Expression of a mutant form of human MAPT (Arg406 Trp), associated with an early onset familial form of demetia, results in a several shortened lifespan. MAPT is implicated in the pathogenesis of Alzeimer's disease and related disorders in humans. Transgenic flies exhibit key features of the human disorders: adult onset, progressive neurodegeneration, early death, enhanced toxicity of mutant tau, accumulation of abnormal tau, and relative anatomic selectivity. However, neurodegeneration occurred without the neurofibrillary formation that is observed in humans disease and some rodent taupathy models [11408621]. | Fly | — | — | — |
| MSRA overexpression | Animals engineered to overexpress bovine MSRA in the nervous system have an extended median lifespan by up to 70% (relative to parental control), increased resistance to oxidative stress, and delayed the onset of senescence-induced decline in activity levels and reproductive capacity [11867705]. | Fly | — | +70 | — |
| Rdh overexpression | Overexpression of Rdh from a doxycycline-inducible promoter results in a 6-17% increase in mean lifespan [12620118].

| Cbs overexpression | Ubiquitous or neuron-specific transgenic overexpression of Cbs enhances longevity in fully-fed animals.
Adult-specific ubiquitous expression of Cbs is sufficient to increase female mean and maximum lifespan by 12 - 43% and 10%, respectively. Males, whose lifespan is relatively less affected by DR, exhibite a smaller, but still significant increase in lifespan by 7% upon Cbs overexpression. Neuronal overexpression also increases lifespan, albeit modestly (approximately 12% mean and 15% maximum lifespan extension), whereas overexpression in the fat body and in the gut has no effect [21930912]. | Fly | +12 to +43 | — | +10 to +15 |
