About 90% of oral cancer is of squamous cell carcinoma type. Surgery and radiation with and without chemotherapy are the major treatments for oral cancer. Better advanced treatment is still needed. Multidrug resistance plays an important role in failure of oral cancer chemotherapy. In this study, we tried to fabricate a novel nanoparticle that could carry both MDR1-siRNA to block MDR1 expression and doxorubicin (DOX), a chemotherapy drug, into cancer cells in order to directly kill the cells with little or no effect of multidrug resistance. Results showed that mesoporous silica nanoparticles (MSNP) can be modified by cationic polymerpolyethylenimine (PEI) to obtain positive charges on the surface, which could enable the MSNP to carry MDR1-siRNA and DOX. The transfection efficiency assays demonstrated that the MSNP-PEI-DOX/MDR1-siRNA was efficiently transfected into KBV cells in vitro. KBV cells transfected with MSNP-PEI-DOX/MDR1-siRNA could effectively decrease gene expression of MDR1 (~70% increase after 72 hours posttreatment) and induce the apoptosis of KBV cells (24.27% after 48 hours posttreatment) in vitro. Importantly, MSNP-PEI-DOX/MDR1-siRNA dramatically reduced the tumor size (81.64% decrease after 28 days posttreatment) and slowed down tumor growth rate compared to the control group in vivo (P<0.05). In the aggregate, newly synthesized MSNP-PEI-DOX/MDR1-siRNA improves cancer chemotherapy effect in terms of treating multidrug-resistant cancer compared to DOX only, clearly demonstrating that MSNP-PEI-DOX/MDR1-siRNA has potential therapeutic application for multidrug-resistant cancer in the future.
