Nucleus-targeted DNA tetrahedron as a nanocarrier of metal complexes for enhanced glioma therapy

Chem Commun (Camb). 2018 Aug 21;54(68):9394-9397. doi: 10.1039/c8cc04021d.

Abstract

A negatively-charged and nucleus-targeted DNA tetrahedron is rationally designed and used as a nanocarrier of positively-charged metal complexes. This tetrahedron speeds up the translocation of metal complexes into the cell nucleus, and inhibits the growth and invasion of glioma cells by triggering vascular mimicry-associated signaling pathways, thus achieving precise glioma treatment.
