Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Analogous to the border customs, liver mainly functions as a filter to detoxify chemicals and metabolite administered orally or intravenously. Besides, the liver cancer cells overexpress the drug exporters which cause high drug effluxion from liver cancer cells, leading to chemoresistance and a diminished chemotherapeutic effect on liver cancer. Recently, we found that RNA nanoparticles display rubber-like property that can rapidly deliver therapeutics to tumor site efficiently and the rest of the RNA nanoparticle were cleared by renal excretion within half hour after systemic injection. Therefore, we designed a new multivalent RNA nanoparticle harboring three copies of hepatocyte targeting-ligands, one copy of miR122, and 24 copies of Paclitaxel to overcome the drug effluxion and chemoresistance thus, synergistically treating HCC. The hepatocyte targeting ligands introduce tumor specificity to the RNA nanoparticles as they selectively bind and internalize into liver cancer cells. The rubber-like RNA nanoparticles allow for enhanced targeting ability to the HCC tumors. The RNA nanoparticles carrying miR122 and PTX were delivered to the liver cancer cells efficiently due to their rubber-like property to enhance their EPR as well as the receptor-mediated endocytosis by hepatocyte targeting-ligands. The miR122 efficiently silenced the drug exporters and the oncogenic proteins. The synergistic effect between miR122 and PTX was confirmed by HSA (Highest Single Agent) synergy model. IC₅₀ was determined to be 460 nM. In vivo studies on mice xenografts revealed that the RNA nanoparticle predominantly accumulated in HCC tumor sites and efficiently inhibited the tumor growth after multiple IV injection. This demonstrates the potential of the rubber-like multivalent RNA nanoparticles to conquest the liver cancer, a currently incurable lethal disease.
