Outline of Final Research Achievements |
Until now, how synthesis and consumption of ATP is balanced inside mammalian cells is unclear. Recently, I invented an ATP indicator fluorescent protein “QUEEN”, which can be used to quantify ATP concentration in single cells. Here, I improved QUEEN and developed a method for usage in mammalian cells. The new version of QUEEN was optimized for measurement at 37 °C and was able to express and observe in mammalian cells. I compared QUEEN signal with another previous method and showed that ATP concentration measured by QUEEN is reliable indeed. I also developed a method to monitor the cell response to metabolic inhibitors. By applying this approach to several conditions and cell species, I aim to make clear the energy balance mechanism in the cells.
