Proliferating eukaryotic cells undergo a finite number of cell divisions before irreversibly exiting mitosis. Yet pathways that normally limit the number of cell divisions remain poorly characterized. Here we describe a screen of a collection of 3762 single gene mutants in the yeast Saccharomyces cerevisiae, accounting for 2/3 of annotated yeast ORFs, to search for mutants that undergo an atypically high number of cell divisions. Many of the potential longevity genes map to cellular processes…

Rapid Nuclear Exclusion of Hcm1 in Aging Saccharomyces cerevisiae Leads to Vacuolar Alkalization and Replicative Senescence

It is shown that yeast aging begins with the nuclear exclusion of Hcm1 in young cells, resulting in loss of acidic vacuoles, and a molecular mechanism regulating vacuolar acidity that signals the end of RLS when acidification is lost is pointed to.

Communications between Mitochondria, the Nucleus, Vacuoles, Peroxisomes, the Endoplasmic Reticulum, the Plasma Membrane, Lipid Droplets, and the Cytosol during Yeast Chronological Aging

This analysis suggests a model for how temporally and spatially coordinated movements of certain metabolites between various cellular compartments impact yeast chronological aging, and suggests a limited set of proteins responds to such changes of the metabolites by altering the rate and efficiency of a certain cellular process essential for longevity regulation.

A functional unfolded protein response is required for chronological aging in Saccharomyces cerevisiae

It is found that cells lacking a functional UPR display a significantly reduced chronological lifespan, which contrasts previous findings in models of replicative aging, and a role for caloric restriction and reduced acid stress in improving ER homeostasis during aging is supported.

Ssd1 and Gcn2 suppress global translation efficiency in replicatively aged yeast while their activation extends lifespan

TRNA overexpression sufficed to extend lifespan in an autophagy-dependent manner in the absence of changes in global translation, indicating that Gcn4-mediatedAutophagy induction is the ultimate downstream target of activated Gcn2, to extended lifespan.

The integrated stress response in budding yeast lifespan extension

It is demonstrated that yeast remains a powerful model system for elucidating conserved mechanisms to achieve lifespan extension that are likely to drive therapeutic approaches to extend human lifespan and healthspan.

Loss of Rer1 causes proteotoxic stress that drives cell competition and inhibits Myc-driven overgrowth

The results show that the increased levels of Rer1 in Myc-overexpression led to the downregulation of Notch activity, consistent with its known function as a negative regulator of the Notch pathway.

Regulation of Lysosomal Function by the DAF-16 Forkhead Transcription Factor Couples Reproduction to Aging in Caenorhabditis elegans

These findings support a model in which protein clearance in the soma is linked to reproduction in the gonad via the active regulation of lysosomal acidification, and implicate the steroid signaling pathway and DAF-16 in dynamically regulating lysOSomal pH in the intestine of wild-type worms in response to the reproductive cycle.

The role of autophagy in the regulation of yeast life span

It is demonstrated that yeast remains an invaluable tool for the identification and characterization of conserved mechanisms that promote cellular longevity and are likely to be relevant to humans, and that the process of autophagy has been implicated in nearly all known longevity‐promoting manipulations and thus represents an ideal target for interventions aimed at improving human health span.

Caenorhabditis elegans model system has critically contributed to these unprecedented aspects of the ER UPR and broadens the possible therapeutic targets to treat the ER-stress associated human disorders and time-dependent physiological deterioration of aging.



The Anaphase Promoting Complex Regulates Yeast Lifespan and rDNA Stability by Targeting Fob1 for Degradation

A mechanistic role played by the APC is provided to promote replicative longevity and genomic stability in yeast and an epistatic interaction between apc5CA and fob1∆ is suggested.

Replication control and cellular life span

The transcriptome of prematurely aging yeast cells is similar to that of telomerase-deficient cells.

The transcriptome of young and old cells isolated by elutriation is analyzed, which allows isolation of biochemical quantities of old cells much further advanced in their life span than old cells prepared by the biotin-streptavidin method, to suggest that old cells are responding to genome instability.

A Functional Analysis Reveals Dependence on the Anaphase-Promoting Complex for Prolonged Life Span in Yeast

Defects in anaphase-promoting complex (APC) activity, which regulates mitotic progression and chromatin assembly, results in genomic instability, a hallmark of premature aging and cancer. We

Genome-wide analysis of longevity in nutrient-deprived Saccharomyces cerevisiae reveals importance of recycling in maintaining cell viability.

A novel approach that combines the power of fluorescence-activated cell sorting with barcode microarray analysis and applies this to determining the importance of every gene in the Saccharomyces cerevisiae genome in a high-throughput, genome-wide fitness screen is presented.

ER-phagy mediates selective degradation of endoplasmic reticulum independently of the core autophagy machinery

It is shown that stress-induced ER whorls are selectively taken up into the vacuole, the yeast lysosome, by a process termed ER-phagy, which represents a distinct type of organelle-selective autophagy.

Autophagy Genes Are Essential for Dauer Development and Life-Span Extension in C. elegans

Using nematodes with a loss-of-function mutation in the insulin-like signaling pathway, it is shown that bec-1, the C. elegans ortholog of the yeast and mammalian autophagy gene APG6/VPS30/beclin1, is essential for normal dauer morphogenesis and life-span extension.
