Bioanalytical and Environmental Chemistry
Research members
Research theme
The aim of our laboratory is to develop new measurement techniques and systems for bioanalysis and medical diagnosis.
All living organisms are composed of a large number and wide range of bio-molecules that act in concert. Therefore, it is very important to sensitively detect such bio-molecules and to elucidate functions and interactions of such bio-molecules. Our research group focuses on the development of comprehensive genome-wide multicomponent analysis. Recently, single-cell analysis is becoming more important as even so-called “homogeneous” cell populations have shown significant cell-to-cell heterogeneity. Thus, our research interest is also focused on the development of single cell trapping and handling devices for further understanding of living organisms.

Eukaryotic cells contain membrane-enclosed organelles that play an important role in cell growth and differentiation. Organelle communication is mediated directly by membrane contacts and indirectly via transport vesicles that transit between organelles. Cytoskeleton regulates organelle movement and the organization of membrane contact sites. We focus on mammalian cells and try to understand the following cellular events.

  1. The interrelationship between the endoplasmic reticulum and other organelles, including mitochondria, the Golgi apparatus, and lipid droplets.

Although several drugs targeting specific molecules have been developed and are used clinically for various cancer treatment, the clinical outcome of patients with metastasis is still poor. We therefore focus on the molecular mechanisms of cancer progression such as colorectal cancer, stomach cancer, or melanoma to develop more effective drugs, using cancer cell lines, gene deficient mice, and human clinical specimens. We also push forward the search of new drug discovery seeds, using chemical library or existing drug library. Recently we also focus on the development of nucleic acid drugs, a new drug category.

Laboratory of Immune Regulation
Research members
Research theme
Macrophages and dendritic cells recognize not only microorganisms from outside of the body, but also dying self-cells to eliminate them by engulfment. This clearance prevents the release of potentially harmful or immunogenic intracellular materials from dying cells. Our laboratory is investigating the molecular mechanisms for recognition and phagocytosis of dying cells by phagocytes, and the pathological relevance of impaired phagocytosis to inflammatory disorders including autoimmune diseases. We are also exploring the mechanisms of neutrophil extracellular trap formation to establish a novel therapy for neutrophil-related diseases.
