Unveiling the "logic" behind the dietary regulation of healthspan

The organismal healthspan is significantly influenced by the quality and quantity of the diet, but our understanding of the detailed molecular mechanisms remains limited. In our laboratory, we study the physiological functions of various nutrients during each life stage, including development, growth, reproduction, and aging. We aim to elucidate the adaptive mechanisms in response to nutritional imbalances, whether transient or chronic, and their impact on molecular mechanisms related to metabolic physiology, tissue homeostasis, feeding behavior, stress response, reproductive capacity, and overall lifespan.
