Our laboratory is conducting research toward the realization of healthy longevity, mainly from the viewpoint of metabolism. There are various themes such as bile acids, gut flora, cancer, and central nervous system, and since the study group focuses on experiments, each of them is conducting research while utilizing the time other than the study group. In the experiments, we use mice, fruit flies, nematodes, etc. as model animals and conduct various in vivo tests. Using functional natural substances, we are conducting a wide range of research in the fields of non-illness and anti-aging.
