Abstract

The first example of mitochondrial delivery of the anticancer drug doxorubicin (Dox) is presented by lipid-functionalized DNA nanocages (LNCs). Dox localized in mitochondria induces significant cytotoxicity and cellular apoptosis in MCF-7 compared with Dox localized in lysosomes. These results suggest that LNC has the potential to be an outstanding tool in the treatment of specific organelle-related diseases such as cancers. Delivery of the anticancer drug doxorubicin to mitochondria by lipid-functionalized DNA nanocages (LNCs) is demonstrated for the first time. The results suggest outstanding potential for the use of LNCs as drug nanocarriers in treatments for organelle-specific diseases.
