| Outline of Final Research Achievements |
In this research project, we focus on a small vesicle secreted out of a cell called exosome (Ex) as a vehicle to deliver miRNA molecules to a target tissue in the living body. Overexpression of two genes that is involved in biogenesis of Ex resulted in the increase amount of secreted Ex from the cells. In addition, we already obtained two different miRNA like molecules that increase radio-sensitivity of cells when introduced into cells. However, since we have not been able to clone a key gene that is involved in enclosure of RNA molecules into Ex, we could not examine the function of the gene.
