The major interest in this laboratory is to understand how cellular functions such as signal transduction, membrane traffic, transport, growth and secretion are regulated in a Ca2+-dependent manner by biomolecular interactions of enzymes, receptors, adaptor proteins and other protein factors. Basic knowledge in biochemistry, cell biology and molecular biology is required.

Current projects are as follows:

  1. Cellular response to Ca2+ -stimulation by drugs, amino acids, cytokines etc.
  2. Structures, functions and ligand-recognition mechanisms of the penta-EF-hand Ca2+-binding protein ALG-2.
  3. Regulation of cell death by cellular factors in relation to Ca2+.
  4. Regulation of intracellular transport of macromolecules by Ca2+.

Microtubule network in spherical hepatocytes

The human health is closely related with the metabolic conditions, which is greatly affected by nutrition. In this lab, we are investigating the nutritional regulation of energy and protein-amino acid metabolism. It has been recently elucidated that branched-chain amino acids (BCAA) have great effects on the protein and glucose metabolism.

How can liver, a metabolic center organ, keep hepatocyte-phenotype? We have found that cultured hepatocytes with spherical cell shape can keep high levels of liver specific phenotype and that some liver-enriched transcription factors such as HNF-4. We are now focusing our effort on 1) identification of a regulatory transcription factors controlling HNF-4 by cell shape and 2) molecular mechanism of signal transduction pathway from cell shape to nucleus. Recently we are also trying to establish artificial liver support system by using spherical human hepatoma cells.

Current projects are follows:

  1. Nutritional regulation of gene expression in animals.
  2. Molecular mechanism of hepatocytes differentiation of 3-dimentional culture.
  3. Physiological significance of liver clock.
  4. Regulatory mechanism for the BCAA catabolism.
  5. Regulation of glucose metabolism by BCAA.
