Yeast as a model for medical and medicinal research

In the past, studies using the yeast Saccharomyces cerevisiae enabled major breakthroughs in the understanding of basic cellular and molecular processes. Today, the use of yeast is undergoing a 'rebirth' in both fundamental and applied research. Indeed, advances in yeast technology have paved the way for a variety of new genome-wide screening approaches. Experimental strategies using yeast aim to unravel disease-related molecular events and to discover novel medicinal compounds. In this article, the impact of yeast as an experimental tool for disease-related studies is summarized and the use of yeast in high-throughput screenings for pharmacological purposes is evaluated. The recently applied and promising approach of so-called humanized yeast systems is also discussed.
