    Whole-body Sirt1 deletion in the adulthood Whole-body deletion of Sirt1 in the adulthood results in mice which are seemingly normal in every way. When mice were given low doses of resveratrol after Sirt1 was disabled, there were no discernible improvement in mitochondrial function or any paramenter, while mice with normal Sirt1 function given reservatrol showed dramatic increases in energy, mitochondrial biogenesis and function, AMPK activation and increased NAD+ levels in skeletal muscle. When mice lacking Sirt1 were given low doses of reserveratrol, AMPK was unaffected. When doses were significantly increased in these mice, AMPK was activated in a SIRT1-indepent manner, but still no benefit to mitochondrial function resulted [22560220]. Mouse
    rsks-1 mutation rsks-1 deletion mutants also live longer. TOR RNA interference further extends lifespan of rsks-1 mutants [17266679]. Worm
    rrf-1 mutation Although rrf-1(pk1417) mutants seem to have elevated DAF-16 activity (as sod-3 transcript level is increased) the mean and maximum lifespan or ability to withstand elevated temperature is not different from wild-type [22574120]. Worm
    ATG7 deletion ATG7 deletion reduces chronological lifespan by 70% [19302372]. Yeast
    VPS27 deletion Under starvation conditions VPS27 deletion mutants have a dramatically reduced lifespan [20953148]. Yeast
    ATG18 deletion The replicative lifespan of ATG18 deletion mutant is not shorter than that of wild-type under DR [18690010]. Yeast
    HNRNPD deletion 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 [Pont et al., 2012]. Mouse
    Prkar2b knockout Loss of function of Prkar2b results in mice that are lean and insulin sensitive. Both median and maximum lifespan is increased by 14%. Median lifespan is increasesd (from 884 to 1005) and 80% lifespan increased from 941 to 1073 days. There is no difference either in median or 80% lifespan in female genotypes [19536287].

    CKA2 deletion CKA2 deletion approximately doubles mean chronological lifespan under starvation/extreme DR in BY4741 also increases as well as as heat-shock resistance in SDC medium in the W303-1A and DBY746 genetic backgrounds [20657825]. Yeast
    CKB2 deletion Lack of Ckb2 promotes a modest but significant chronological lifespan extension and marked increase in yeat resistance [20657825]. Yeast
    VPS21 deletion Lack of VPS21 reduces lifespan under starvation conditions to a level similiar to that of wild-type cells incubated in synthetic complete medium and therefore blocked the lifespan-extending effect of DR [20657825]. Yeast
    VPS8 deletion Lack of VPS8 reduces lifespan under starvation conditions to a level similiar to that of wild-type cells incubated in synthetic complete medium and therefore blocked the lifespan-extending effect of DR [20657825]. Yeast
    VPS36 deletion VPS36 deletion mutant had a chronological lifespan as long as wild type BY4741. Thus, Vps36 is not necessary for the starvation/extreme DR-dependent lifespan extension [20657825]. Yeast
    CUP9 deletion Deletion of CUP9 increases replicative lifespan by 30% in the alpha and a strains [18340043]. Although CPU9 was identified as a potential long-lived mutant strain in a bar-code screen, the chronological lifespan of CUP9 deletion mutant is not significantly different from than of wild-type under starvation/extreme DR [20657825]. Yeast
    APD1 deletion Although APD1 was identified as a potential long-lived mutant strain in a bar-code screen, deletion of APD1 does not significantly affect chronological lifespan under starvation/extreme DR [20657825]. Yeast
    ZTA1 deletion Deletion of ZTA1 increases replicative lifespan by 15% in the alpha strain and decreased by 10% in the a strain [18340043]. Although ZTA1 was identified as a potential long-lived mutant strain in a bar-code screen, deletion of ZTA1 does not significantly affect chronological lifespan under starvation/extreme DR [20657825]. Yeast
    SSN2 deletion Although SSN2 was identified as a potential long-lived mutant strain in a bar-code screen, deletion of SSN2 does not significantly affect chronological lifespan under starvation/extreme DR [20657825]. Yeast
    ACB1 deletion ACB1 deletion extends chronological lifespan under starvation/extreme DR. Similar heat-shock resistance and resistance to a very hight concentration of acetic acid (but not resistance to oxidative stress) was enhanced by the deletion of ACB1. Deletion of ACB1 in W303-1A and DBY746 genetic backgrounds on synthetic complete media causes severe growth defects and sightly shorter lifespan and also heat-sensitivity [20657825]. Yeast
    TRM9 deletion TRM9 deletion almost triples mean chronological lifespan under starvation/extreme DR, increases heat resistance, but reduces resistance to acetic acid. Similar effect were present in the BY746 background in SDC medium [20657825]. Yeast
    RPL12B deletion Deletion of RPL12B increases mean replicative lifespan by 20% in the alpha strain [18423200] and by 22% in the remade strain, but increases non-significantly the mean replicative lifespan by 13% in the ORF collection [22377630]. RPL12B mutation promotes mean chronological longevity extension and heat-shock resistance but reduces acetic acid resistance under starvation/extreme DR. In DBY746 mutation of RPL12B almost doubles mean chronological lifespan in SDC medium and increases heat-shock resistance [20657825] Yeast
    ARO7 deletion Under starvation/extreme DR deletion of ARO7 increases mean chronological lifespan and confers higher resistance to heat-shock, but made cell more sensitive to acetic acid and leads to growth defects. In W303-1A background ARO7 deletion causes an even more severe growth defect and mutants are short-lived [20657825]. Yeast
    FAR3 deletion Deletion of FAR3 significantly reduces mean chronological lifespan under starvation/extreme DR relatively to wild-type [20657825]. Yeast
    FAR11 deletion Deletion of FAR11 significantly reduces mean chronological lifespan under starvation/extreme DR relatively to wild-type [20657825]. Yeast
    PPG1 deletion PPG1 deletion reduces significantly mean chronological lifespan under starvation/extreme DR [20657825]. Yeast
    BUL1 deletion Deletion of BUL1 does non-significantly reduces mean chronological lifespan under starvation/extreme DR [20657825]. Yeast
