  • Title: Screening for genetic modifiers of amyloid toxicity in yeast.
    Author: Giorgini F, Muchowski PJ.
    Journal: Methods Enzymol; 2006; 412():201-22. PubMed ID: 17046660.
    Abstract:
    In recent years the facile, yet powerful, genetics of the baker's yeast Saccharomyces cerevisiae has been appropriated for the study of amyloid toxicity. Several models of amyloid toxicity using this simple eukaryotic organism have been developed that faithfully recapitulate many disease-relevant phenotypes. Furthermore, these models have been exploited in genetic screens that have provided insight into conserved mechanisms of amyloid toxicity and identified potential therapeutic targets for disease. In this chapter, we discuss the strengths and weaknesses of yeast models of amyloid toxicity and how experiments with these models may be relevant to amyloid disorders. We suggest approaches for development of new yeast models of amyloid toxicity and provide an overview of screening protocols for genetic modifiers of amyloid toxicity by both random and systematic approaches.
