Outline Activities
(1) Vascular endothelium: My main research interest is endothelial signal transduction. I have clarified mechanosensitive endothelial responses, focusing on ATP release mechanisms. Furthermore, I have examined the effects of various hazardous environments, such as hypoxia, glucose overload and hyperlipidemia, on endothelial functions.
(2) I have developed an in vitro reconstruction system of smooth muscle contraction, using cultured smooth muscle cells, and examined the detailed contractile mechanisms of vascular and airway smooth muscle cells. Especially I have established the in vitro model system of airway hyperresponsiveness and revealed the possible involvement of RhoA and MMP-1 in hyperresponsiveness.
(3) in silico drug discovery: I have been using in sillico screening for discovering anti-cancer metastatic drugs.
(4) I have developed in silico drug repositioning system and have been conducting experiments to prove the usefulness of this system.

I give lectures of introduction to pharmacology, autonomic pharmacology, CNS pharmacology, endocrine pharmacology, pulmonary pharmacology and gastrointestinal pharmacology to undergraduate medical students (3rd grade), and conduct students' practice of autonomic nerve drugs and cardiovascular drugs.

Social activities:
I have been involved in the 'Ground Research Announcement for Space Utilization" promoted by NASDA , JAXA and Japan Space Forum.

    1996.04~2002.12ATP release pathway in vascular endothleial cells. ATP is released from vascular endothelium in response to mechanical stress. I have clarified that mechanosensitive ATP release is obtained through volume-regulated anion channels..
Current and Past Project

  • The purpose of this poject was to clarify the effects of gravity change on endothelial functions and their molecular emchanisms.

Professional and Outreach Activities
There would be various changes in vascular functions in microgravity, and therefore clinical courses of cardiovascular diseases and malignancy of astronauts may be different from those on earth, especially in a long term. I have examined the effects of gravity on endothelial functions especially mechanosensitivity as research commissions with Japan Aerospace Exploration Agency..
