    sug overexpression Overexpression of sug (from a doxycycline-inducible promoter) results in a 5-9% increase in mean lifespan [12620118]. Fly +5 to +9
    Sod2 overexpression Overexpression of Sod2 by 5-115% decreases lifespan by 4-5% without any compensatory changes in metablic rate, level of physical activity, or the levels of other antioxidants (Sod, Cat, and glutathione) [10545213]. Targeted overexpression of Sod2 in motor neurons alone extends lifespan by 30% [11113599]. Induced overexpression of Sod2 in adult animals extends lifespan up to 37% [12072463]. Overexpression of catalase in combination with SOD2 has no added benefit for lifespan [12072463]. Animals overexpressing SOD2 or catalase do not exhibit a decrease in metabolism as measured by oxgen consumption [12072463]. Sod2 overexpression results in a 20% increase in mean and maximum lifespan [18067683]. Fly +20 to +37 +20
    Rdh overexpression Overexpression of Rdh from a doxycycline-inducible promoter results in a 6-17% increase in mean lifespan [12620118]. Rdh is an open reading frame in the first intron of the encore gene [12620118]. Fly +6 to +17
    Eip71CD overexpression Overexpression of Eip71CD (alias MsrA) in nervous system extends the lifespan by up to 70%, increases resistance to oxidative stress, and delays the onset of senescence-induced decline in activity levels and reproductive capacity. Eip71CD is a downstream effector of foxo [22310715]. Mean and maximum lifespan is increased by up to 2-% in animals that overexpress Eip71CD [20655917]. Fly +20 to 70 +20
    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
    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
    Hsp68 overexpression Overexpression of Hsp68 extends modestly (by around 15%) median and maximum lifespan [14602080]. There is a consistent and significant lifespan extension by 20% in both males and females when hsp68 is overexpressed in somatic cells. hp68 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]. Fly +20 +15 +15
    Hsp27 overexpression Overexpression of Hsp27 (by the UAS/GAL4 system) increases stress resistance and extends the mean lifespan by 30% [15308776]. Fly +30
    Hsp26 overexpression Overexpression of Hsp26 (by the UAS/GAL4 system) increases stress resistance and extends the mean lifespan by 30% [15308776]. Fly +30
    hep overexpression Overexpression of hey significantly extends median (50%) and maximum (25%) lifespan [14602080]. Fly +50 +25
    GLaz overexpression 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]. Fly +29
    Mt2 overexpression Overexpression of Mt2 extends mean and maximum lifespan [15533947]. Fly
    Ef1alpha48D overexpression Overexpression of Ef1alpha48D (transformed with a P-element vector and under control of hsp70 regulatory sequences) results in lifespan extension by 18-41% [2508089]. Fly +18 to +41
    Neural-specific POSH overexpression 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]. Fly +14
    p53 overexpression Overexpression of wild-type Dmp53 during adult life has no significant effect on lifespan [16303568]. Fly
    cher overexpression Overexpression of cher from a doxycycline-inducible promoter results in a 7 - 9% increase in mean lifespan (in PdL x rtTA; Oregon-R x rtTA) [12620118]. Fly +7 to +9
    Cct1 overexpression Overexpression of Cct1 from a doxycycline-inducible promoter results in a 6 - 8% increase in mean lifespan (in the PdL x rtTA; Oregon-R x rtTA strain) [12620118]. Fly +6 to +8
    Sod overexpression Simultaneous overexpression of catalase and Sod (alias Sod1) results in a one-third lifespan extension, a slower rate of mortality acceleration, and a delayed loss in physical performance, but neither has any effect on lifespan alone [8108730]. General overexpression of Sod (also known as Cu/ZnSOD) alone is sufficient to extend lifespan by up to 48%. Simultaneous overexpression of catalase with Cu/ZnSOD has no added benefit, presumably due to a pre-existing excess of catalase [9858546]. Fly +38
    Cat overexpression Simultaneous overexpression of catalase and Sod1 results in a one-third (i.e. 30%) lifespan extension, a slower rate of mortality acceleration, and a delayed loss in physical performance, but neither has any effect on lifespan alone [8108730]. Targeted overexpression of CAT in the mitochondrial matrix has no effect on lifespan at 25 degree Celsius, slightly shortens lifespan at 29 degree Celsius as is associated with increased resistance to endogenous hydrogen peroxide, paraquat, and cold stress [12521602]. Fly
    Gadd45 overexpression Gadd45 overexpression in the nervous system leads to a significant increase of lifespan without a decrease in fecundity and locomotor activity. The lifespan extension effect is more pronounced in males than in females. Additional maximum lifespan is also extended. The maximum lifespan is increased by 50% and 59% for females and males, respectively. The median lifespan is extended by 46 and 77% for females and males, respectively [22661237]. Fly
    Constitutive active S6k overexpression Overexpression of a constitutively active form of S6k (alias dS6K) decreases mean lifespan by 34% at 29°C [15186745]. Fly -34
    Sir2 overexpression Overexpression of Sir2 (alias dSir2) extends lifespan by up to 57% and specifically median lifespan by 40-60%. Ubiquitous Sir2 overexpression causes a 4-fold increase in Sir2 mRNA expression and an up to 57% increase in average lifespan (29% for females and 18% for males). A 10 - 20% increase in Sir2 mRNA levels causes no lifespan extension. Neuronal Sir2 overexpression extends average lifespan by 52% in females and 20% in males. Motor-neuronal specific expression fails to cause lifespan extension. DR fails to cause further increase in lifespan or even reduces lifespan toward normal of dSir2 overexpression mutants [15520384]. Mild Sir2 overexpression in the fat-body extends lifespan and reduces relative body fat content in both males and females [22661237]. A diet-dependent lifespan phenotype of dSir2 overexpression in the fat-body, but not in muscles, negates the effects of background genetic mutants [23246004]. Fly +18 to + 57 +4- to +60
    foxo overexpression foxo overexpression extends lifespan. Activation of foxo in the adult pericerbral fat body is sufficient for lifespan extension [15175753]. Overexpression of foxo in the adult adipose tissue alone prolongs lifespan [15192154; 15175753]. Limited activation of foxo reduces the expression of Drosophila insulin-like peptide dilp-2 synthesized in neurons and, represses endogenous insulin-dependent signaling in peripheral fat body [15175753]. foxo overexpression in adult fat body under normal nutritional conditions leads to extension of lifespan of females and causes a right shift of the response curve of lifespan to DR [18241326]. Overexpression of dFOXO in adult fat body increases median, by 21-33%, and maximum lifespan as well as lowers the age-specific mortality at all ages, in two independent experiments. Overexpression of dFOXO increases lifespan by lowering the whole mortality trajectory, with no effect on slope (similar to DR). Initiation of dFOXO expression at different ages increases subsequent lifespan with the magnitude of increase decreasing as the animals were put on RU486 (which activates the foxo transgene via UAS) at older ages. The effects of removal of dFOXO overexpression at different ages closely mirrored those of induction of expression and produce shortest lifespan observed in animals taken of RU486 at the earlier ages [17465980]. Fly +21 to +33
    Thor overexpression Ubiquitously overexpression of wild-type Thor (alias d4E-BP) causes no change under AL, but an activated allele (with more than 3-fold increased binding activity to delF4E) significantly extends lifespan of females (weak allele) and females as well as males (strong allele). Mean lifespan is extended by 11 to 40%. Median lifespan of males and females is enhanced by by 11 and 22%, respectively. Maximum lifespan is extended by 16 and 18% for males and females, respectively. Under DR (0.25% YE) there is no lifespan extension, beyond the effect of DR alone, in all (wild-type, weak and strong) Thor alleles [19804760]. Lifespan of animals with increased Pten and 4E-BP activity in muscle exhibit and extended mean and maximum lifespan by 20% and 15.8% [21111239]. Fly +11 to +40 +11 to +22 +16 to +18
    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].
