Factors

We need to know every factor which determines lifespan.

Lifespan factors often but not always originate from defined genetic elements. They are not just genes, by definition they can be anything for which a Classifications schema can be build for that is related to the regulation of lifespan, such entities may include Single-Nucleotide Polymorphism, transcript variants, proteins and their complexes, compounds (i.e. small molecules like metabolites and drugs), etc. A factor should be based on a defined molecular entity or genomic position and been classified. It shall be highly flexible and scalable Concept.

While individual lifespan factors within each species or precise defined molecular entities will be captured within the Lifespan App, Data Entries of the Data App may summarize for instance the relevance of each factor class (e.g. homologous group; chemical derivate of related structure and properties, etc.) as well as draw overall conclusions. o

    BMH1 Brain Modulosignalin Homologue 1 Deleting BMH1 extends chronological lifespan by 25% and is associated with activated stress response, decreased ROS levels and increased heat-shock-element-driven transcription activity. BMH1 deletion was non-additive with the genetic DR mimetic cdc25 and tor1. Water starvation (a form of extreme DR) extends chronological lifespan of BMH1 mutant even more as it does in wild-type. BMH1 genetically interacts with DR as well as TOR- and PKA-signaling pathways to regulate lifespan. Phosphorylation of Ser238 on Bmh1 increases during chronological aging, which is delayed by DR or reduced TOR activity [19805817]. Budding yeast
    BRE5 BREfeldin A sensitivity 5 Deletion of BRE5 increases mean replicative lifespan by 30% [16293764] and mean chronological lifespan in diploid cells [21447998] Budding yeast
    CCR4 Carbon Catabolite Repression 4 Deletion of CCR4 increases mean chronological lifespan by 20 - 41% (20, 33, 41) in diploid cells [21447998]. In W303R CCR4 deletion shortens replicative lifespan by approximately 80% and results in temperature sensitivity that is suppressed by SSD1-V. SSD1-V partially suppresses the short-lifespan of ccr4 mutant. CCR4 mutation is synthetically lethal in combination with deletion of MPT5 in the absence of SSD1-V [11805047]. Budding yeast
    CRC1 CaRnitine Carrier 1 Deletion of CRC1 increases replicative lifespan [16293764]. CRC1 deletion increases replicative lifespan by 25% in the alpha strain [19030232] Budding yeast
    CKB2 Casein Kinase Beta' subunit Lack of Ckb2 promotes a modest but significant chronological lifespan extension and marked increase in yeat resistance [20657825]. Budding yeast
    CTT1 CaTalase T 1 Overexpression of cytosolic catalase T CTT1 alone slightly shortens stationary phase survival in strain DBY746. Overexpression CTT1 in combination with SOD1 increases stationary phase survival by about 10% [12586694]. Mutational inactivation [20696905] or deletion [21076178] of CTT1 lead to a longer chronological lifespan. Budding yeast
    CDC6 Cell Division Cycle The CDC6-1 conditional allele results in an approximately 20% increase in mean replicative life span. This allele is defective for replicative initiation form the rDNA ARS at 27 degree Celsius, resulting in a reduced rate of extrachromosomal rDNA circle accumulation [9428525]. The cdc6-1 allele results in genomic instability at the permissive temperature [8552037]. Budding yeast
    CDC25 Cell Division Cycle 25 The CDC25-10 allele extends mean and maximum replicative lifespan by 34% and 18%, respectively, at 30 degree Celsius. cdc25-10 mutants have an extended replicative lifespan under AL. Growth on 0.5% glucose restriction does not further extend replicative lifespan of cdc25-10 mutants. CDC25 null mutant is not viable. CDC25 appears to act in the same genetic pathway as SIR2 and NPT1 and is suggested to be genetic model of DR [11000115]. Budding yeast
    LAG1 Ceramide synthase component A gene deletion of LAG1 in haploid cells results in a pronounced increase (approximately 50%) in mean and in maximum replicative lifespan in the YPHDF-1A strain [8195187], but has no significant effect on lifespan in stains W303R or PSY316 (N. Bishop, G.Liszt, and L. Guarente, unpublished]. The LAG1 transcribed is preferentially expressed in young cells. LAG1 null mutant is viable and has no obvious phenotypes but shows delayed ER to Golgi transport when combined with DGT1 mutation [10198056] and is synthetical lethal with LAC1 deletion. Budding yeast
    CTF8 Chromosome Transmission Fidelity 8 Deletion of CTF8 increases mean chronological lifespan by 15-92% (15, 18, 42, 45, 92) in diploid cells [21447998]. Budding yeast
    CSR2 Chs5 Spa2 Rescue 2 Deletion of CSR2 results in higher levels of intracellular reactive oxygen species, augmentation of scavenging enzymes and extends replicative as well as chronological lifespan [16336970]. Budding yeast
    CKA2 CK2 subunit 2 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]. Budding yeast
    CYR1 CYclic AMP Requirement 1 The CDC35-1 allele of the adenylate cyclase CYR1 confers a 75% extension of replicative lifespan at 25 degree Celsius [11000115]. Transposon-mutagenized CYR1 increases resistance to oxidants and extends chronological lifespan by up to 90%. Stress-resistance transcription factors Msn2/Msn4 and protein kinase Rim15 are required for this lifespan extension [11292860]. CYR1 mutation is assumed to act as genetic DR mimetic [11000115]. The CDC35-1 allele of the adenylate cyclase CYR1 confers a 75% extension of replicative lifespan at 25 degree Celsius [11000115]. cyr1-1 mutation extends median chronological lifespan by 28-47% and is non-addative with lifespan extension conferred by overxpression of human MAPK1 [17662940]. Budding yeast
    CLN3 CycLiN 3 Overexpression shortens chronological lifespan together with age-dependent increases in genome instability and apoptosis. While around 80% of wild-type cells are alive almost non CLN3 overexpressers are alive (under condition that avoids adaptive regrowth) [17710147]. Budding yeast
    CPR7 Cyclosporin-sensitive Proline Rotamase 7 Deletion of CPR7 has no effect on lifespan replicative lifespan, but increases chronological lifespan [11361336] Budding yeast
    COX4 Cytochrome c OXidase 4 COX4 (subunit of cytochrome oxidase) deletion decreases mitochondrial membrane potential in rho+ cells to a value intermediate between rho+ and rho0 as well as increases mean and maximum replicative lifespan by 24% and 55%, respectively. Deletion of either RTG2 or RTG3 abrogated the replicative lifespan extension by COX4 deletion. ERC levels in cox4Delta rho+ cells was the same or lower than in rho+ cells [22303396]. Budding yeast
    REI1 Cytoplasmic pre-60S factor REI1 deletion increases mean replicative lifespan by about 40% [16293764] in the alpha and a strains [19030232]. Budding yeast
    DNM1 Dnm1p Deletion of DNM1 extends significantly mean and maximum lifespan by 49 and 111% in FY10 strain and by 15 and 12% in BY4741 strain [17173038]. Budding yeast
    ERG5 ERGosterol biosynthesis 5 Deletion of ERG5 decreases replicative lifespan by 35% in the a strain [18340043], but increases mean chronological lifespan by 26 - 116% (26, 40, 43, 62, 116) in diploid cells [21447998]. Deletion of ERG5 cancels out the replicative lifespan extension of 0.5% glucose restriction [18690010]. Budding yeast
    FRE6 Ferric REductase 6 FRE6 deletion increases mean replicative lifespan by 14% and cancels out the lifespan extending effect of DR [22912585]. Budding yeast
    FOB1 FOrk Blocking less 1 Mutation in FOB1 extends replicative lifespan by 30-50% [10230397]. FOB1 mutation increases replicative lifespan by 25% in the alpha strain and by 10% in a strain [19030232]. FOB1 mutant exhibit an about 20% mean replicative lifespan increase [15722108]. Deletion of FOB1 causes extension in the short life span of the sir2 mutant by around 50% [10521401]. Mutation of the FOB1 gene slows the generation of rDNA circles and thus extends lifespan by approximately 30% in W303 and 50% in K2307 [10230397]. Even in cells lacking both Sir2 and Fob1, nicotinamide prevents the lifespan extension by DR [16311627]. Budding yeast
    FBP1 Fructose-1,6-BisPhosphatase 1 Deletion of FBP1 increases survival during the first 15 days during chronologocal aging, but does not increase chronological lifespan. FBP1 deletion reduces production of reactive oxygen species while overexpression of FBP1 shortens chronological lifespan [16199065]. Budding yeast
    GPA2 G Protein Alpha subunit 2 Deletion of GPA2 increases mean and maximum replicative lifespan by 40% and 26%, respectively [11000115]. Deletion of GPA2 extends replicative lifespan by reducing cAMP-PKA activity and provides a genetic model for DR [11000115]. Budding yeast
    GPR1 G-Protein coupled Receptor 1 Deletion of GRP1 increases mean and maximum replicative lifespan by 41% and 26%, respectively. GRP1 deletion mutants have also longer chronological lifespan. Deletion of GPR1 extends replicative lifespan by reducing cAMP-PKA activity and provides a genetically model for DR [11000115]. Budding yeast
    GIS1 GIg1-2 Suppressor 1 Deletion of GIS1 increases replicative lifespan by 25% in the alpha strain [19030232] and causes major although not complete reversion of chronological lifespan extension by 0.5% glucose restriction [18225956]. Budding yeast
