| Outline of Final Research Achievements |
Metallomics is the name given to the integrated research field of biometals. Metallomics and research on metallome require analytical techniques that can provide information for the identification and quantification of metal species. The hitherto techniques for bio-trace elements including metals/metalloids have been applicable to massive samples such as blood serum, tissue extract and urine. However, analytical techniques for metallomics research using cultured cells are needed. Thus, in this study, we intended to reveal novel techniques for metallome analysis using cultured cells and novel concepts for the metabolism of bio-trace elements by the novel techniques. The first outcome in this study is the development of “element array” technique to analyze changes in entire elements with a cellular event. The second is to propose new reactive molecular species, “reactive cyanogen species” which act as a detoxificant of excess amounts of intracellular selenium.
