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

    CTA1 CaTalase A 1 CTA1 overexpression partially suppresses the shortened chronological lifespan by ISC1 mutation [21707788]. Budding yeast
    DAP2 Dipeptidyl AminoPeptidase 2 DAP2 deletion decreases mean and maximum replicative lifespan under AL by 19 and 36%, respectively, and cancels out the lifespan extending effect of moderate DR [22912585]. Budding yeast
    CDC13 Single stranded DNA-binding protein found at TG1-3 telomere G-tails; regulates telomere replication through recruitment of specific sub-complexes, but the essential function is telomere capping Decreased replicative lifespan Budding yeast
    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
    SNF4 Sucrose NonFermenting 4 Deleting SNF4 extends replicative lifespan by 10-20% in S288C strain [10921902]. Budding yeast
    RPL43A Ribosomal Protein of the Large subunit 43A Deletion decreases mean replicative lifespan by 60% in the alpha strain and by 50% in a strain [18423200] as well as -64% in the ORF collection, but increases mean replicative lifespan by 16% in the remade strain [22377630]. Budding yeast
    PHO85 PHOsphate metabolism 85 Deletion decreases replicative lifespan by 45% in the alpha strain [18340043], but increases mean chronological lifespan in diploid cells [21447998] Budding yeast
    YKU70 Subunit of the telomeric Ku complex (Yku70p-Yku80p) Deletion fo YKU70 shortens lifespan, but does not accelerate the normal aging process [10521401]. YKU70 null mutants are defective for non-homologous end-joining [8754818] and for telomeric silencing [9635192]. Budding yeast
    RAD52 RAD51 homolog (RecA homolog, E. coli) (S. cerevisiae) Deletion in RAD52 causes a 75% reduction in mean replicative lifespan in PSY316 strain [10207108]. Similiar reduction of lifespan occurs in strains W3031-A and W303R [M. Baeberlein, M. McVey, and L. Guarente, unpublished]. RAD51 is required for formation of extrachromosomal rDNA circles [10207108], but not for replication fork pausing nor DNA breakage with the rDNA [10693764]. Budding yeast
    RAS1 Deletion in RAS1 increases mean (23%) and maximum (29%) replicative lifespan (in SP1) [8034612]. RAS1 deletion increases replicative lifespan by 15% in the alpha strain [19030232]. However, deletion of RAS1 slightly shortens chronological lifespan (in SP1) [12586694]. No lifespan extension results from overexpression of RAS1 (in SP1) [8034612]. Budding yeast
    LOC1 Nuclear protein involved in asymmetric localization of ASH1 mRNA; binds double-stranded RNA in vitro; constituent of 66S pre-ribosomal particles Deletion increased mean (25.1 -> 36.7) and maximum replicative lifespan in BY4742 [18423200]. Replicative lifespan increased by 40% in the alpha strain [19030232]. Budding yeast
    SSF1 Constituent of 66S pre-ribosomal particles, required for ribosomal large subunit maturation; functionally redundant with Ssf2p; member of the Brix family Deletion increased mean (25.1 -> 38.5) and maximum replicative lifespan in BY4742 [18423200]. Replicative lifespan increased by 60% in the alpha strain [19030232]. Budding yeast
    YPT32 Yeast Protein Two 32 Deletion increases mean chronological lifespan by 13 - 45% (13, 17, 45) in diploid cells [21447998]. Budding yeast
    PAN2 Poly(A)-binding protein-dependent poly(A) riboNuclease 2 Deletion mutant of PAN2 live approximately as long as wild-type under starvation/extreme DR [20657825]. Budding yeast
    RPN4 Regulatory Particle Non-ATPase 4 Deletion mutants of the C2H2 zinc-finger transcription factor RPN4, are characterized by a reduced non-adaptable proteasome pool and display a 37 - 53% and 22-33% reduction in mean and maximum replicative lifespan. TOR1 deletion extends rpn4 replicative lifespan. Severe DR by reducing glucose concentration to 0.05% increased replicative lifespan of rpn4 mutants. RPN4 transcription is controlled by HSF1 [21931558]. Budding yeast

    ACO2 ACOnitase 2 Deletion of ACO2 increases replicative lifespan by 20% in the alpha strain and decreases it by 10% in the a strain [18340043]. Its deletion increases mean chronological lifespan by 6 - 44% (6, 22, 20, 20, 19, 44) in diploid cells [21447998]. Budding yeast

Adh1 is oxidatively modified during aging and its activity becomes reduced. Overexpression of ADH1 by introducing and extra copy increases mean replicative lifespan by 30% as well as slightly chronological lifespan and was associated with increased Sir2 activity [17975074].
