Ageing (and hence longevity) is intimately related to the ability of an organism to cope with both intrinsic and extrinsic stresses. Nutrient starvation is one of the common but major stresses for all organisms. We use Saccharomyces cerevisiae as a model to understand how eukaryotic cells regulate starvation-specific gene expression and how this regulation impacts on cell survival (chronological aging).


Currently, two complementary approaches are adopted to address the issue. One is to reveal the genetic interaction network governing stress response and chronological ageing. The other is to elucidate the mechanisms by which the nutrient starvation signals are transmitted and converged on transcription factors responsible for the activation of stress response. Furthermore, the knowledge gained from both approaches is being applied to develop novel expression systems for biotechnology.
