| Outline of Final Research Achievements |
Mitochondria have attracted interest as an organelle that can be used as a target in medical therapy, in the maintenance of beauty & health and the development of the life sciences. The objectives of the research supported by this grant is to develop a nano device that can be used for regulating mitochondrial gene expression including mitochondrial gene silencing and mitochondrial transgene expression. In this study, we report on the successful mitochondrial delivery of nucleic acids in human cells using a MITO-Porter, which is a liposome-based carrier that is capable of introducing macromolecular cargos into mitochondria via membrane fusion. Moreover, we achieved mitochondrial RNA knockdown and mitochondrial transgene expression using such a MITO-Porter system. Our system for regulating mitochondrial gene expression system promises to have a significant impact on the medical and life sciences.
