    We aim for understanding how nutrients influence tissue homeostasis and organismal survival in molecular level using fruit fly, Drosophila melanogaster. Dietary restriction (DR) has been shown to extend lifespan in diverse organisms including mammals. However, tissue-specific effects of DR on aging have not fully understood. We are mainly focusing on how DR impacts on intestinal homeostasis including gut permeability, intestinal stem cell activity and inflammation which are known to be affected by age. We are also interested in understanding how different tissues or cells communicate each other upon different nutrient conditions and age to maintain tissue homeostasis.
