| Gclc | Glutamate-cysteine ligase catalytic subunit | Overexpression of Gclc extends mean and maximum lifespan by up to 50% [16148000]. | Fruit fly |
| Gclm | Glutamate-cysteine ligase modifier subunit | Overexpression of Gclm extends the mean lifespan by up to 24% [16148000]. | Fruit fly |
| gig | gigas | Overexpression of gig, also known as dTsc2, results in lifespan extension. Overexpression of dTsc2 increases mean lifespan by 20% and 12%, at 25°C and 29°C, respectively, and protects from deleterious effects of rich food, as if mimicking the effect of DR [15186745].
Overexpression of dTsc2 via a UAS promoter in the eye using the driver gmr-GAL4 or in the nervous system by using appI-GAL4 does not extend the lifespan. Using the drivers 24BGAL4 and PO188-GAL4, enhancer traps that are predominantly expressed in the muscle and fat results in mean lifespan extension of 27% and 37%, respectively, at 29°C [15186745]. Fat-specific drivers DJ634-GAL4 and PO163-GAL4 when used to overexpress dTsc2, also led to a mean lifespan extension of 22% and 31%, respectively, at 29°C [15186745]. | Fruit fly |
| GLaz | Glial Lazarillo | Overexpression of GLaz results in increased resistance to hyperoxia (100% O2) and a 29% extension of mean lifespan under normoxia. Lifespan was also extended 30-60% under starvation [16581512]. Loss-of-function mutation of GLaz which decreases its expression of GLaz results in shorter lifespan and decreased resistance to oxidative stress in males [16581513]. | Fruit fly |
| Trxr-1 | Thioredoxin reductase-1 | Overexpression of Trxr-1 (alias GSR; glutathione reductase) in transgenic flies results in increased lifespan and oxidative stress resistance, but only under hyperoxia [10506576]. | Fruit fly |
| hk | hook | Loss of function mutation in hk decreases mean lifespan by 58 - 60% and maximum lifespan by 15 - 47% [17435236]. | Fruit fly |
| Hsp23 | Heat shock protein 23 | Overexpression of Hsp23 increases mean lifespan by more than 30% and increases the premortality phase [14734639]. | Fruit fly |
| Hsp26 | Heat shock protein 26 | Overexpression of Hsp26 (by the UAS/GAL4 system) increases stress resistance and extends the mean lifespan by 30% [15308776]. | Fruit fly |
| Hsp27 | Heat shock protein 27 | Overexpression of Hsp27 (by the UAS/GAL4 system) increases stress resistance and extends the mean lifespan by 30% [15308776]. | Fruit fly |
| Hsp68 | Heat shock protein 68 | Overexpression of Hsp68 extends modestly (by around 15%) median and maximum lifespan [14602080]. Hsp68 is activated by the JNK pathway and target gene of foxo [20976250].
There is a consistent and significant lifespan extension by 20% in both males and females when hsp68 is overexpressed in somatic cells. hsp68 overexpression using GMR-Gal4, and eye-specific driver that expresses Gal4 in salivary glands has no effects. Hsp78 overexpression using the weaker 5961FS driver moderately but significantly extends lifespan [20976250]. | Fruit fly |
| Hsp70Bc | Heat-shock-protein-70Bb | Overexpression of the Hsp70 locus (containing Hsp70Bb and Hsp70Bc) in transgenic flies extends lifespan as much as 7.9% [9363888]. | Fruit fly |
| Indy | I'm not dead yet | Flies heterozygotic for a disruption in Indy gene have extended mean (87-92%) and maximum (45%) lifespan. Homozygotes for the disruption show only a 10 - 20% increase in mean lifespan [11118146]. Heterozygous insertion of a p-element in the non-coding region of Indy locus leads to a reduction in Indy mRNA expression and causes a significant median lifespan extension in male and female by about 29% and 34%, respectively. At normal or high calorie conditions Indy heterozygote mutants have a significant lifespan extension, but under low calorie conditions, Indy heterozygous mutants have minimal median lifespan extension. Reduction of calorie content from high to normal calorie condition results in 19% decline in Indy mRNA and from normal to low calorie condition results in additional 9% decrease in Indy mRNA. Reduction of calorie content from high to normal calorie conditions in heterozygous Indy mutants leads to 20% reduction in Indy mRNA expression without any additional decrease upon further reduction to low calorie food. Maximum lifespan extension is associated with Indy mRNA levels between 25 - 75% of normal. Long-lived heterozygous Indy mutants on high-calorie food and normal wild-type on low-calorie food have several phenotypes in common: 50 - 60 % reduced mRNA expression levels of Ilp2, Ilp3 and Ilp 5; similar high percentage of anti-FOXO-positive nuclei in fat body cells; higher sensitivity to starvation; do not gain weight; similar decrease in triglycerides and fat storage; normal food intake [19470468].
Mutations in Indy dramatically extend lifespan without a loss in fertility, physical activity, flight velocity or metabolic rate [11118146; 12626742]. Indy encodes a high-affinity dicarboxylate/citrate plasma membrane transporter found most abundantly in adult fat body, oenocytes and midgut cells, the primary sites of intermediary metabolism [12391301]. Indy mutation alters metabolism in a manner similiar to DR and mutants have several phenotypes with long-lived DR files in common, including decreases insulin-like signaling, lipid storage, weight gain, and resistance to starvation, and an increase in spontaneous physical activity [19470468].
Of the Indy206 and Indy302 mutation only one of the two has lower mRNA levels and both do not extend lifespan of female flies in any genetic background. In original genetic background only Indy mutation associated with altered RNA expression extends the lifespan of males. This effect is abolished by back-crossing into standard out-bred genetic backgrounds and is associated with an unidentified locus on the X chromosome. Original Indy line with long-lived males is infected by the cytoplasmic Wolbachia. Longevity of Indy males disappear after tetracycline clearance of this endosymbiont [17571923]. | Fruit fly |
| InR | Insulin-like 1 receptor | Mutations in InR (InRE19/InRp5545 transheterozygous) result in dwarf females with extended lifespan of up to 85% and dwarf males with reduced late age-specific mortality (although no significant change in lifespan) [11292875]. InrGC25/InrE19 transheterozygous animals are short-lived an exhibit an elevated rate of age-independent mortality [11292874].
Natural allelic variation in InR are associated with variation in lifespan [15013662; 20074316]. | Fruit fly |
| lt | light | Loss-of-function mutation of lt reduces mean lifespan by 47% and maximum lifespan by 10% [17435236]. | Fruit fly |
| Mnt | CG13316-PC, isoform C | A dMnt null allele results in flies with larger cells, increased weight, and decreased lifespan [16055719]. | Fruit fly |
| mth | methuselah | Mutants in mth display approximately 35% and 36% increase in average and maximum lifespan as well as enhanced resistance to various forms of stress (including starvation, high temperature, and dietary paraquat) [9794765].
Reduced expression of mth targeted only to the insulin-producing cells of the brain is sufficient to extend lifespan and to enhance oxdative stress resistance [23121290].
IPC-targeted overexpression of β-arrestin alone mimics the longevity phenotype of reduced mth signaling [23121290]. | Fruit fly |
| mys | myospheroid | mys mutants exhibit ameliorated age-related declines in locomotor activity and an increase in mean lifespan of 20% [14570233]. | Fruit fly |
| NF1 | Neurofibromin 1 | NF1 mutants have a shortened lifespan and exhibited increased vulnerability to heat and oxidative stress as well as reduced mitochondrial respiration and elevated ROS production. Overexpression of NF1 increases mitochondrial respiration and reduced ROS production. It increases mean lifespan by 49% in males and 68% in females and maximum lifespan by 38% in males and 52% in females. It also improved reproductive fitness [17369827]. | Fruit fly |
| Orco | Odorant receptor co-receptor | Loss-of-function mutation in Orco (alias Or83b) results in olfactory defects, altered adult metabolism, enhanced stress resistance, and life-extension. Fully fed female homozygous Or83b null mutants exhibit a 56% increase in median lifespan and a 30% increase in maximum lifespan. Males are also significantly longer-lived, though to a smaller degree and maximum lifespan is not extended. Heterozygous mutants of both sexes show an intermediate longevity. Lifespan of homozygous Orco null mutants is further increased by DR, but the relative increase in median and mean longevity is significantly greater when mutants were maintained in well-fed conditions [17272684].

| ovo | — | The dominant ovoD1 allele extends female lifespan by approximately 50%. It does not synergize or prevent life-extension caused by chico [10617470; 11292874].
ovoD1 mutants are sterile [Mevel-Ninio et al. 1991]. | Fruit fly |
| p53 | — | Overexpression of wild-type p53 during adult life has no significant effect on lifespan. Expression of dominant-negative versions of p53 in adult neurons extends lifespan by 58% in females and by 32% in males and increases resistance to genotoxic stress and resistance to oxidative stress, but not to starvation or heat stress, while not affecting egg production or physical activity.
Dominant negative p53 expression cancels out lifespan extension effect of DR, low calorie-food (5% SY). Muscle or fat body specific expression of a dominant negative form of p53 as well as globally lack of p53 decreases lifespan [16303568]. Loss of p53 activity slightly shortens the lifespan. Mutants that lack p53 survive well up to 50 days, but mortality rate increases relative to wild-type at later ages. p53 mutant animals are extremely sensitive to irradiation [12935877].
Expression of dominant-negative (DN) form of p53 in adult neurons, but not in muscle or fat body cells, extends median lifespan by 19% and maximum lifespan by 8%. The lifespan of dietary-restricted flies is not further extended by simultaneously expressing DN-DMp53 in the nervous system, indicating that a decrease in Dmp53 activity may be part of the DR lifespan-extending effect. Selective expression of DN-Dmp53 in only the 14 insulin-producing cell (IPCs) in the brain extends lifespan to the same extent as expression in all neurons and this lifespan extension is not additive with DR [17686972].

| Pcmt | Protein-L-isoaspartate (D-aspartate) O-methyltransferase | 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]. | Fruit fly |
| Pka-C1 | cAMP-dependent protein kinase 1 | PKA-overexpressing flies (hsPKA*/+) have an about 30% extended maximum lifespan [17369827]. | Fruit fly |
| POSH | Plenty of SH3s | Neural-specific overexpression of POSH extends the mean lifespan of adult flies by 14% at 25°C. Ectopic expression of POSH during development results in morphological abnormalities [11868902]. | Fruit fly |
| puc | puckered | Heterozygous loss-of-function mutations in puc (either pucA241.1 or pucE69) significantly extend median and maximum lifespan and increase resistance to oxidative stress. Heterzyogosity for puc only modestly extends lifespan in animals carrying a hypomorphic allele of the JNK kinase hep [14602080].
puc heterzyogotes do not differ signficantly from wild-type for body size, reproductive activity or developmental timing, but exhibit increased resistance to oxidative stress and starvation [14602080]. | Fruit fly |
