Theme

Peptide Sciences Emerge to Open Up New Therapeutic Windows Against Cardiovascular Diseases

This laboratory investigates the pathophysiological roles of vasoactive peptides and their molecular mechanisms in the formation of atherosclerosis and angiogenesis.

1) Atherosclerosis working group assesses the modulatory effects of novel peptide hormones on atherosclerosis and its related diseases. Among numerous peptides recently identified, we sorted them into two groups: good or bad for atherosclerosis. We would like to produce the peptide-based treatments, such as analogues using good ones and receptor blockers against bad ones, and diagnostic biomarkers, which will become useful in the new future clinical practice.

2) Angiogenesis working group investigates the molecular mechanisms of angiogenesis regulated by TGF-β in vivo. Further, we elucidate the role of TGF-β signaling in tumor metastases under their microenvironment.
