An ideal nano drug delivery agent must be potent enough to carry high dose of therapeutics and competent enough in targeting specific cell of interest, having adequate optimized physiochemical properties and biocompatibility. Carrying differentially polar therapeutics simultaneously will make them superior in their class. However, it is of enormous challenge to the researchers to find such a unique nanocarrier and to engineer all of the above-mentioned features into it. In this manuscript, we have shown for the first time that apoferritin (Apf) can carry and deliver high dose of doxorubicin (Dox), docetaxel (Doc), and combination of both Dox and Doc specifically into the cancer cell and enhances killing compared to free drug without any functionalization or property modulation. In addition, we have shown that Apf alone is noncytotoxic in nature and interacts with intracellular tubulin/microtubule. Drug loaded Apf specifically bound and consequently internalized into the human breast cancer cell line (MCF7) and human cervical cancer cell line (HeLa) through receptor mediated endocytosis process and releases either single or combination of drugs in the endosome. We have also checked the binding efficacy of both drugs using molecular docking. Further, using fluorescence microscopy, we have shown that Apf can deliver combination of drugs inside cancer cells and the drugs exerts their effect thereof. Finally, we have studied the efficacy of Apf complexes with individual drugs and in combination compared to free drugs in a tumor mimicking 3D multicellular spheroid model of HeLa cell. © 2016 American Chemical Society.
