Group Amphibian Development

Staff/ YAOITA Yoshio (Professor), TAKASE Minoru (Associate Professor),
NAKAJIMA Keisuke (Assistant Professor), TAZAWA Ichiro (Assistant Professor)

    We focus on the molecular mechanism of amphibian development and the differentiation, development and function of endocrine organs by making use of various techniques in experimental embryology, cell biology, molecular biology, gene engineering and genome editing.

Key Words Metamorphosis, Programmed Cell death, Thyroid hormone, Gonad, Germ cell

Group Evolution and Diversity Resulting from the Life Cycle

Staff/ SUZUKI Atsushi (Associate Professor), KURABAYASHI Atsushi (Assistant Professor), ISLAM Mohammed Mafizul (Assistant Professor), TAKEBAYASHI-SUZUKI Kimiko (Assistant Professor (Special Appointment))

    Current amphibian diversity is a product of the life cycle that has evolved since the birth of life. We engage in pioneering research to reveal the processes and mechanisms mediating diversity, and we strive to maintain and preserve diversity across a wide range of biological hierarchies at the gene–genome–chromosome, cell–tissue, individual, population, species, and higher taxonomic levels.

Key Words Evolution, Diversity, Endangered species, Preservation, Phylogeny, Morphogenesis, Early development

Group Genetic Information and Environmental Impact

Staff/ KASHIWAGI Akihiko (Professor, Special Appointment), FURUNO Nobuaki (Associate Professor), MIURA Ikuo (Associate Professor), HANADA Hideki (Assistant Professor), KASHIWAGI Keiko (Assistant Professor (Special Appointment))

    The aim of our amphibian based research is to investigate 1) gene function using transgenic, knockout and other techniques, 2) oogenesis and oocyte maturation mechanism, 3) sex determination mechanism, 4) possible effects of environmental pollutants, gravity and magnetic fields, and 5) chromosome abnormality.

Key Words Gene function, Oogenesis and oocyte maturation, Sex determination, Environmental pollutants, Gravity and Magnetic fields, Chromosome abnormality

The Only One Research Institute and Resource Center for Amphibian Studies

    This is a unique institute in the world, in that it can stably keep and maintain amphibians, which have various advantages as experimental animals. Making use of this feature, the Institute pursues pioneering research and leads the world in the fields of development, inheritance, and evolution. Currently, the Institute maintains species of wild and mutant amphibians, genetically modified amphibians and endangered amphibians, and works to establish and provide standard inbred strains of the tropical clawed frog (Silurana tropicalis) as model amphibian species. Through such activities, the Institute aims to form a global hub for amphibian research.
