Systematic collections of single-gene deletions have been invaluable in uncovering determinants of lifespan in yeast. Overexpression of a single gene does not have such a clear outcome as cancellation of its function but it can lead to a variety of imbalances, deregulations and compensations, and some of them could be important for longevity. We report an experiment in which a genome-wide collection of strains overexpressing a single gene was assayed for chronological lifespan (CLS).

Loss of heterozygosity (LOH) in a vegetatively growing diploid cell signals irregularity of mitosis. Therefore, assays of LOH serve to discover pathways critical for proper replication and segregation of chromosomes. We screened for enhanced LOH in a whole-genome collection of diploid yeast strains in which a single gene was strongly overexpressed.

Article Synopsis
  • Destabilization of proteins impairs their metabolic efficiency, and it's unclear how often this causes toxicity.
  • Researchers created temperature-sensitive mutants of the yeast genes ADE2 and LYS2 by altering a few amino acids, leading to reduced fitness from overexpressing these proteins.
  • The study suggests that growth issues arise not only from damaged proteins but also from the energy and processes required to eliminate them, indicating that even slight protein destabilization can lead to toxicity.
