LBR | Lamin B receptor | Overexpression of Lamin B receptor in the adult muscle and in the abdominal fat body results in a 54% and 46% reduction of mean lifespan, respectively [18494863]. | Fruit fly |
mir-277 | — | Constitutive miR-277 expression shortens lifespan and synthetically lethal with reduced insulin signaling, indicating that metabolic control underlies this phenotype. Transgenic inhibition with a miRNA sponge construct also shortens lifespan [23669073].
miR-277 is downregulated during adult life [23669073].
mir-277 controls branched-chain amino acid catabolism and as a result it can modulate the activity of TOR kinase [23669073]. | Fruit fly |
MAPT | microtubule-associated protein tau | 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]. | Human |
GH1 | Growth hormone 1 | 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]. | Cattle |
Gh | Growth hormone | 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 signs of premature aging such as a shortened lifespan, glomerulosclerosis and glomerulonephritis, increased astrogliosis, and early onset of age-related changes in cognitive function [14583653]. | House mouse |
Terf2 | telomeric repeat binding factor 2 | Overexpression results in signs of premature ageing. | House mouse |
Trp53 | Transformation related protein 53 | Mice heterozyogous for an allele of p53 that removes the 5' portion of the protein demonstrate decreased cancer, permature aging phenotypes, and shortened lifespan in the mixed inbred C57BL/6â129/Sv background. It has been proposed that the this allele of p53 results in increased activity/overexpression [11780111]. Decreased activity of Trp53 results in increased cancer and decreased apoptosis. Mutant mice with activated Trp53 display enhanced resistance to spontaneous tumours and signs of premature ageing including reduced lifespan, osteoporosis, organ atrophy and a diminished stress tolerance [11780111]. However, super-p53 mice generate by a transgenic copy of a large genomic segment containing an intact and complete copy of p53 have an ehanced response to DNA damage, are significantly protected from cancer and had no indication of accelerated aging [12426394]. super-Ink4a/Arf/p53 mice have a synergic protection against cancer and delayed aging [Workshop RoSyBa 2011]. | House mouse |
