| 内容記述 | Epigenetics is thought to be involved in highly advanced life phenomena, and its regulation has created new opportunities in regenerative medicine. Mintbody (modification-specific intracellular antibody) can track a posttranslational protein modification in epigenetics using a genetic system encoded within a single chain of variable fragments tagged with a fluorescent protein. Magnetic resonance imaging (MRI) is a technique that allows observation of specific molecules in living organisms. The ferritin heavy chain (FTH1) is one of the MRI reporters used in mammals. The combination of FTH1 with mintbody may show remarkable ability as a reporter for MRI to investigate epigenetics in the deep part of a living organism. This article discusses the suitability and safety of FTH1 for use in the analysis of epigenetics by MRI. Cells expressing the FTH1 hybrid of mintbody showed insufficiently increased sensitivity by MRI even in the presence of excess iron. After incubation with ferric ammonium citrate, DNA damage was found in cells expressing the FTH1 hybrid of mintbody. The use of FTH1 as a genetically encoded reporter for MRI appears to be limited by the requirement of metal and its relatively low sensitivity. These results suggest future directionality and the possibility of studying epigenetics in vivo. | |||||
