| Outline of Final Research Achievements |
In order to visualize specific mRNA and its translated products simultaneously at a single molecular level in eukaryotic cells, we developed a new microscopy with single molecule sensitivity, and established various cell lines of Saccharomyces cerevisiae and human, which stably express reporter genes. Because Saccharomyces cerevisiae exhibited strong autofluorescence in the cytoplasm, we used plasma membrane localization reporter genes. In human cell lines, we used a microtubule-binding reporter gene. In both cases, we succeeded in visualizing specific reporter proteins in a single molecule sensitivity. In addition to reporter proteins, we also tried to visualize its mRNA in a single molecule sensitivity.
