| Outline of Final Research Achievements |
In the present study, out of 120 compounds, we found that Cu(II)(Edtc)2 (Cu10), a organic-inorganic hybrid molecule, strongly induces metallothionein (MT) synthesis without non specific cell damage in human vascular endothelial cells. We also showed that Cu10 is easily taken up by vascular endothelial cells, and that Cu10 induce MT synthesis via metal response element-binding transcription factor-1 (MTF-1) pathway but not Nrf-2 pathway. Cu10 also induces MT synthesis in other cell types such as human brain microvascular pericytes and human coronary artery smooth muscle cells. However, the stimulatory effect of Cu10 was weaker than Cu10-stimulated vascular endothelial cells, suggesting that Cu10 has more strong activity on MT synthesis in vascular endothelial cells. These observations suggest that Cu10, a organic-inorganic hybrid molecule, may have a potential to contribute for prevention of vascular diseases including atherosclerosis.
