Molecular evolution



Expansion of genomic information has enabled us to illustrate the evolutionary history of many genes and organisms. We combine experimental and computational approaches to figure out evolutionary events. The new nomenclature of HSP70 we proposed has been listed in many databases.

Metabolite tracing using 13C and NMR



We are analyzing the function of the unique metabolic pathway by combining molecular approaches and the NMR-based metabolite-tracing technology pioneered at Yale.

Our main target includes the bdelloid rotifer Adineta vaga that has acquired massive bacterial and fungal genes by horizontal gene transfer.

Calorie restriction & maternal effect



Maternal calorie restriction (CR) is known to increase offspring's lifespan in an emerging invertebrate model called rotifers. We are investigating the composition of eggs from calorie-restricted and fed mothers to clarify the mechanism underlying the maternal CR effect.

We also study stress proteins, cell cycle regulators, autophagy, and population dynamics of monogonont rotifers.

Morphological studies



Biology used to be a field to describe the natural wonders of the world with a reverence for the diversity. I still like the concept. We report morphological characteristics of animals in Southeast Asia using histological approaches from evolutionary point of view.

Energy metabolism & food science

Although vertebrates share many basic biochemical pathways such as glycolysis and TCA cycle, their detailed metabolic features are diverse especially when illustrating dynamic processes. For example, fish generally prefers amino acids and lipids over carbohydrate as energy source. Nitrogen waste products can be either ammonia, urea, or uric acid depending on species and environment.

We investigate the metabolic diversity in various animals. Recent keywords are fish, lipid distribution, oxidative stress etc. Understanding fish metabolism also contribute to food science and aquaculture.
