GHR | growth hormone receptor | Individuals with low GH/IGF-I signaling due to a defect in the growth hormone receptor (GHR) are protected against cancer. Among the human individuals with a defect in GHR no cancer deaths were observed. GHR deficiency does not appear to extend lifespan because it is associated with increased risk of heart disease [21325617]. Variants in GHR were found to be associated with longevity [19489743]. | Human |
Lamp2a | lysosomal-associated membrane protein 2 | Lamp2a, the receptor for chaperone-mediate autophagy (CMA) decreases in abundance with age. Maintaining the amount of the Lamp2a (in a double transgenic mice) specifically in the liver at levels found in young adults prevents age-dependent decrease in receptor abundance at the cellular and organ levels. In this mice CMA activity is maintained until advanced ages which results in preservation of the autophagic activity and is associated with lower intracellular accumulation of damaged proteins, better ability to handle protein damage and improved organ function [19115216; 18690243]. Lamp2a expression restored not only CMA but also macrophagy and proteasomal degradation to the level observed in young liver as well as `youthful` mitochondrial function and cellular ATP abundance and overall youthful liver functions [18776878].

IL6 | interleukin 6 (interferon, beta 2) | Elevated IL-6 serum levels are associated with diseases, disability and mortality in the elderly. The proportion of homozyogtes for the G allele at -174 locus (a promoter genetic variability) decreases centenarian males, but not centenarians females. Only males, homozygous for the G allele at -174 locus have higher IL6- serum levels. Individuals who are genetically predisposed to produce high levels of IL-6 during aging (i.e. -174 locus GG homozygous men) are disadvantaged for longevity [11500818]. | Human |
TSHR | thyroid stimulating hormone receptor | Two single nucleotide in the TSHR were associated with increased TSH in both centenarians and their offspring [19837933].TSHR was found to be associated with longevity [19837933]. TSHR was not found to be associated with longevity [19837933]. | Human |

RNA intereference of let-4 extends mean and 75%ile lifespan by 4%, but reduces maximum lifespan by 25% [22768380]. | Nematode |
WRN | Werner syndrome, RecQ helicase-like | Mutation in WRN causes Werner Syndrome which characteristics includes prematurely aged facies, scleroderma-like skin changes, cataracts, arteriosclerosis, subcutaneous calcification, and diabetes mellitus [McKusick et al. 1963; 5327241]. Inheritance is autosomal recessive and malignancy is frequent. THe frequency is 3 per million individuals in Japan [7460386].
Cells from a Werner heterozygote exit the cell cycle at a faster rate than do normal cells [8265666]. Loss of WRN promoter aberrant mitotic recombination [11316787].
The single nucleotide polymorphism rs1800392 in WRN has been associated with exceptional longevity in a plethora of genetic signatures [22279548]. WRN was found to be associated with longevity [10069711; 20855428; 20855428; 20855428 ;17903295; 22406557; 16405962; 16405962; 16405962; 20855428; 20855428; 20855428; 22279548]. WRN was found to be associated with longevity [24244950]. | Human |
Ucp3 | uncoupling protein 3 (mitochondrial, proton carrier) | Metabolic intensity (daily food energy/body mass) correlates with longevity in MF1 mice. The animals with the highest quartile of metabolic intensities have a mean lifespan of 36% longer than animals with the lowest quartile of metabolic intensities. The highest metabolism of long-lived animals can be attributed to increased uncoupling Ucp3 [15153176].
Skeletal muscle mitochondria isolated from high metabolism mice are more uncoupled that those from low metabolism mice [15153176]. | House mouse |
UCHL1 | ubiquitin carboxyl-terminal esterase L1 (ubiquitin thiolesterase) | UCHL1 is assoicated with Parkinson's disease [9774100]. UCHL1 belongs to a family of de-ubiquitinating enzymes responsible for the hydrolysis of bonds between ubiquitin molecules and small adducts [11084366]. Decreased activity due to mutation may result in decreased labeling of abnormal proteins for clearance. | Human |
SAG12 | senescence-associated protein 12 | Expression of SAG12 is specifically activated by developmentally controlled senescence pathways but not by stress- or hormone-controlled pathways [10579486; 10579487]. | — |
RTG2 | ReTroGrade regulation 2 | RTG2 is required for replicative lifespan extension associated with the retrograde response, a pathway that signals the functional status of mitochondria to the nucleus to regulate the expression of several genes [11024000]. RTG2 is not required for replicative lifespan extension by DR [11024000].
RTG2 null mutants are not petite [8422683], but display various nutrient auxotrphies and alterations of carbohydrate metabolism [7727418]. | Budding yeast |
PSEN1 | presenilin 1 | Mutations (more than 60 different) in PSEN1 are associated with Alzheimer's disease, of which all result in increased production of abnormally long amyloid beta-protein and an increase in senile plaque formation [10934557].PSEN1 was found to be associated with longevity [17903295]. | Human |
PARK2 | parkinson protein 2, E3 ubiquitin protein ligase (parkin) | Parkin loss of function (e.g. due to deletion or point mutations) results in autosomal recessive juvenile parkinsonism, a form of Parkinson's disease with age of onset below 40 years. Associated phenotypes include resting tremor, rigidity, bradykinesia and postural instability is associated with selective neurodegeneration of the pigmented neurons in the brain stem (substiantia nigria and locus coereus) as well as the presence of intracytoplasmic inclusion bodies (Lewy bodies) [4735177].PARK2 was found to be associated with longevity [22279548]. | Human |

unc-51 | UNCoordinated-51 | unc-51(e369) mutation reduces mean but extends maximum lifespan. unc-51(e369) mutation reduces lifespan of eat-2(ad1116) mutants to that of wild-type [18219227]. | Nematode |
NAC | N-acetyl cysteine | Treatment with 10 mM of NAC has no effect on the lifespan of wild-type, but fully abolishes the increased longevity of nuo-6 and severly limits that of isp-1. At high concentration (> 10-15 nM) NAC can be become deleteroius even on the wild-type [21151885]. | Nematode |
Vitamin C | — | Treatment with 1 mM vitamin C has no effect on lifespan of wild-type, but significantly shortens the lifespan of both isp-1 and muo-6 mutants [21151885].
Supplementation with vitamin C normalizes the median lifespan of wnr-1 and mir-124 mutants, which both exhibit premature aging [23075628]. | Nematode |
PPG1 | Protein Phosphatase involved in Glycogen accumulation 1 | PPG1 deletion reduces significantly mean chronological lifespan under starvation/extreme DR [20657825]. | Budding yeast |

HNRNPD | eterogeneous nuclear ribonucleoprotein D (AU-rich element RNA binding protein 1, 37kDa) | HNRNPD controls inflammation by turning off the inflammatory response to stop the onset of septic shock. Cessation of inflammatory cytokine respisne is mediated partly through cytokine mRNA degradation facilitated by RNA-binding proteins, including HNRNPD. HNRNPD deletion leads to accelerated aging as evidenced by strinking telomere erosion, markedly increased DNA damage repsosne at telomere ends, pronounced cellular senescence and rapid premature aging that increases with successive generations. HNRNPD which is a family of four related genes also maintains the integrity of chromosomes by activating telomerase, because HNRNPD strongly activates the transcription promoter for Tert [Pont et al., 2012]. | House mouse |
