| Outline of Final Research Achievements |
1.To establish a novel gene expression system controlled by light and magnetic field in vivo, we generated and examined chimeric transcription factors composed of truncated form of cryptochrome, a blue light and magnetic field-responsible transcription factor, GAL4BD and VP16AD. No reactivity to blue light and magnetic field was observed for the chimeric transcription factors.
2.Main approaches of light-selective gene delivery rely on the light-dependent enhancement of transfection efficiency. Studies focused on light-stimulated inhibitory regulation of transfection have rarely been reported. Our experiments revealed that jetPRIME-mediated transfection was strongly inhibited by blue light. Partial exposure of a culture vessel to blue light resulted in selective gene delivery into cells grown on the unexposed area of the vessel. By using this approach, different types of plasmid DNA were delivered into different areas in the culture vessel.
