| Outline of Final Research Achievements |
We investigated the involvement of intracellular copper homeostasis in SOD3 regulation during monocytic differentiation into macrophage. We confirmed that the alteration of copper homeostasis after phorbol ester (TPA) treatment regulates SOD3 expression. Moreover, Atox-1, a copper chaperone, functions as a transcription factor of SOD3. It raises the possibility that the alteration of copper homeostasis after TPA treatment changes histone modification, especially in histone acetylation. Overall, our results suggest that intracellular copper ion functions as a key molecule for the redox regulation, and better understanding the role of copper ion might lead to improve vascular diseases.
