    2-ME treatment Animals fed a diet supplemented with 2-mercaptoethanol (2-ME) exhibit an increased mean and maximum lifespan [6334792]. T-cell-dependent immune responses are higher in the 2-ME-fed mice compared to the controls when the animals are young. The accumulation of fluorescent products of lipid peroxidation damage is also delayed in the lymphocytes of the 2-ME-fed mice and tumor onset and incidence is reduced in these animals [6334792]. 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
    30% Dietary restriction 30% dietary restriction starting at 2 months of age increases overall, average, median and maximal lifespan. Knockout of Ghr failed to respond with lifespan extension to this regimen [16682650]. Mouse
    Acacb knockout Acacb-null animals (alias Acc2-/-) exhibit upon regular diet an increase triglyceride breakdown, leaner phenotype, increased insulin sensitivity and no effect on lifespan [17923673]. Mouse
    Adcy5 knockout Adcy5 knockout mice are to cardiac stress and have an increased median lifespan of 30% as well as an increased maximal lifespan of 12%. Further, they are also protected from age-related reduced bone density and susceptibility to fractures, and reduced cardiac function [17662940]. Mouse +30 +12
    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
    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
    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
    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
    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
    Bub1b mutation Bub1b mutation decreases median lifespan by 60% (from 15 to 6 months). Bub1b mutant mice develop many phenotypes suggestive of accelerated aging, including: progressive bilateral cataracts, substantial loss of sub dermal adipose tissue, spinal kyphosis, muscle atrophy, and decreased wound healing. Moreover, there is a pronounced increase in senescent associated Beta-galactosidase expression in late generation Bub1b mutant mice, indicative of increased rate of cellular senscence. Homozyogous knockout of Bub1b results in lethality, while heterozygous animals exhibit no aging phenotypes [15208629]. Mouse -60
    Bub1b mutation The median and maximum lifespan of mice with a nonsense mutation 2211insGTTA in BubR1 is significantly reduced. BubR1(+/GTTA) mice develop several aging-related phenotypes at an accelerated rate, including catarct formation, lordokyphosis, skeletal muscle wasting, impaired exercise ability, and fat loss. Further BubR1(+/GTTA) mice develop mild anaplodies and exhibit enhanced growth of carcinogen-induced tumors [Wijshake et al. 2012]. Mouse
    Bub1b overexpression Sustained high-level expression of BubR1 preserves genomic integrity and reduces tumorgenesis (even in the presence of genetic alterations that strongly promote aneuplodization and cancer, such as oncogenic Ras) and extends the lifespan and delays age-related deterioriation and aneuploidy in several tissues [23242215]. BubR1 overabundance exerts its protective effect by correcting mitotic checkpoints defects [23242215]. BubB1 overexpression extends maximum lifespan by 20 - 41% compared to GFP-carrying control transgenic mice [23242215]. Mouse +20 to +41.3
    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
    C3 treatment Tris-malonic acid derivate of the fullerene C60 molecule (C3) increases the lifespan of Sod2(-/-) mice by 300% [15451059]. Mouse +300
    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
    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
    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
    Cisd2 knockout Cisd2 knockout shortens lifespan resulting in premature aging [19451219]. Mouse
    Cisd2 overexpression A persistent level of Cisd2 achieved by transgenic expression extends mean, median and maximum lifespan without any apparent deleterious side effects [22661501]. Mouse
    Coq7 knockout Mice heterozygous in Coq7 live about 15 to 30% longer than controls [16195414]. Mouse +15 to +30
    Ctf1 knockout Absence of Ctf1 is associated with decreased arterial fibrosis, stiffness mad senescence and increased longevity. Ctf1-null mice have a decrease in arterial stiffness and decrease in levels of inflammatory, apoptotic and senescence, whereas telomere-linked and DNA repair proteins as well as antioxidant enzyme activities are increased. The median lifespan of Ctf1-null mice is increased by 5 month (18%) [23172930]. Wild-type and Ctf1-null mice exhibit an increase of senescence markers (p53, Mdm2, p21, and p16) with age but are lower in Ctf1-null mice. Ctf1-null mice have a diminished vascular NFκB signaling, lower inflammation and oxidative stress and reduced senescence. Ctf1-null mice have a 12% increase in body weight, 130% increased adiponectin levels and 51% decreased leptin concentrations [23172930]. Mouse +18
    Decreased Trp53 Decreased activity of Trp53 results in increased cancer and decreased apoptosis. Mouse
    Diabenol treatment In female NMRI and transgenic HER-2/neu mice supplementation of diabenol with drinking water 5 times a week since the age of 2 months, increases survival and inhibits spontaneous carcinogenesis. In NMRI diabenol does not influence body weight gain dynamics, food and water consumption, but slowed down age-related disturbances in estrous function and increases the lifespan of all and 10% most long-living ones. Diabenol treatment in NMRI mice also inhibits spontaneous tumor incidence (mammary and lymphomas mainly) and increases mammary tumor latency. Diabenol treatment slows down age-related changes in estrous function in HER-2/neu mice, but fails to influence survival and slightly inhibited the incidence and decrease the size of mammary adenocarcinoma metastasis into the lung [15754958]. Mouse
    Dietary restriction on high-fat diet Dietary restriction on a high-fat diet increases both mean and maximum lifespan by 36% compared to the high-fate diet control group [22509016]. Mouse +36 +36
