Our laboratory seek to clarify mechanisms of life at molecular, organelle, cellular, organic and body levels with a new approach 'Systems Physiology' combining physiological experiments 'wet experiments' and mathematical analysis 'dry experiments'.

Satoshi Matsuoka M.D., Ph.D., ProfessorCEO

I am interested in how functions of cell, organ and body are organized by orchestrating various elements (proteins) especially in heart. We challenge this problem by performing a multi-level experiments combined with mathematical analysis. Molecular biological study, electrophysiological study, fluorescence imaging, motion analysis as well as mathematical modeling and analysis are used. With this approach, we clarified how individual ion channels/transporters play in cardiac excitation-contraction coupling, rhythm generation of heart (automaticity) and cell volume regulation. The representative mathematical model is a model of comprehensive cardiac myocyte, Kyoto model.
We investigate also functions of non-excitable cells, such as lymphocytes. We study how ion channels/transporters, especially mitochondria Ca transporters, regulate lymphocyte response to antigen.

We welcome all who are interested in systems physiology and want to challenge the logic of life.

Yukario Takeda Ph.D., Assistant ProfessorCEO

I have been interested in local Ca signalings in wide variety of cell types (e.g. pacemaker cells within GI tract, vascular smooth muscle cells, and pancreatic beta cells) and their relationships to distinct cellular functions, especially when Ca dynamics are modulated by second messengers. In this lab, I am focusing on cardiac pacemaker cells and lymphocytes. By combining experiments with biosimulation analysis, I am challenging to reveal how local Ca handlings between mitochondria and ER at submembrane spaces control automaticity of the pacemaker cells and lymphocyte response to antigen, particularly when different types of intracellular signaling cascades are stimulated.

Mohammed Moinul Islam M.S., Graduate School Student CEO

I am enthusiastic about how life is mastered by complex activities of biomolecules and this enchantment influenced me to develop my career in the direction of academic teaching and research on medical science. As a PhD research student I am now working on the molecular mechanisms and roles of mitochondrial Ca2+ transporters especially the Na+-Ca2+ exchange system (mediated via NCLX) under the guidance of Professor Satoshi Matsuoka.

Title: Analysis of relationship between migration and calcium dynamics in a tumor cell by using a cell migration chemotactic control technology (supervised by Prof. Matsuoka and Prof. Fujita).
It has been reported that a gradient of intracellular calcium concentration is produced during migration or chemotaxis of a kind of cells. However, it is not clarified whether the same phenomenon occurs in tumor cells. Therefore, I want to clarify the relationship between cell migration and calcium dynamics in tumor cells by using a cell migration chemotactic control technology. In addition to this, I do hope to discover unknown mechanisms underlying tumor cell migration.
