Dr. Alexander de Luna Fors

Principal Investigator

Our laboratory studies gene function and evolution at the systems level. We build and analyze large libraries of yeast mutants in a systematic effort to understand how genes, the environment and their interactions influence complex cellular phenotypes such as growth, survivorship and aging. We use robotic integration to explore how gene expression affects fitness and how duplicate and multifunctional genes impact functional innovation and biological robustness.

Research lines:

Genetics of aging in yeast

  • The genetic architecture of yeast chronological lifespan: searching for genetic aging factors and their genetic interactions.
  • Gene-environment interactions that underlie longevity by dietary restriction.
  • Characterization of pharmacological interventions that extend cellular lifespan and the underlying such phenotypic effects.
  • The natural variation of the mutational effects in yeast aging.

Evolution of gene function

  • Molecular and functional evolution of duplicate genes.
  • Evolution, genetics, and molecular biology of multifunctional proteins.
  • Modifiers of the expression of genes subject to telomere position effect.

Recent projects:

  • “The effect of genes, the environment and its interactions on the aging of yeast “. CONACYT – Basic Science - CB-2015/254365 (2016 - 2019).
  • “Genomic analysis of the cellular mechanisms of the anti-diabetic drug Metformin”. CONACYT National Problems - PN2016/2370 (2018 - 2019).
