| Research Abstract |
In order to get new insights on physiological functions of small peptides, their potentials in tissues such as vessels and muscles were investigated in this study. As a result, it was clarified that basic di-peptides could relax contracted thoraces aorta in an endothelium-independent manner through the suppression of Ca2+-related signaling pathways by cell -line experiments and in silica analyses. Furthermore, we have demonstrated for the first time that the potent vasorelaxation power of basic do-peptides was ameliorated with aging and hypertension. We further got new evidence that basic di-peptides could absorb intact across intestinal membrane by our proposed new visualization technique (MADL-MS), and show anti-diabetic effect in muscle cells.
