Nucleic acids are generally regarded as the payload in gene therapy, often requiring a carrier for intracellular delivery. With the recent discovery that spherical nucleic acids enter cells rapidly, we demonstrate that nucleic acids also have the potential to act as a delivery vehicle. Herein, we report an amphiphilic DNA-paclitaxel conjugate, which forms stable micellar nanoparticles in solution. The nucleic acid component acts as both a therapeutic payload for intracellular gene regulation and the delivery vehicle for the drug component. A bioreductively activated, self-immolative disulfide linker is used to tether the drug, allowing free drug to be released upon cell uptake. We found that the DNA-paclitaxel nanostructures enter cells ∼100 times faster than free DNA, exhibit increased stability against nuclease, and show nearly identical cytotoxicity as free drug. These nanostructures allow one to access a gene target and a drug target using only the payloads themselves, bypassing the need for a cocarrier system.
