Abstract

The combination of nanocarriers and chemotherapy drugs can release the chemotherapy drugs to the tumor tissue, which can enhance the antitumor effect and reduce the adverse reactions at the same time. In this study, a co-delivery system based on hollow mesoporous silica nanoparticles (HMSN) was developed and characterized. We also investigated the in vitro effect of this system on CD117+CD44+A2780 cell line. HMSN was selected as the nanocarrier, with -COOH modified on the surface and doxorubicin (DOX), NVP-AEW 541 (NVP) loaded inside. IGF‑1R was chosen as the drug target, apoptosis rate and expression of cyclin B1, Bax, Bcl-xl, p-Akt were used to evaluate the antitumor effect of HMSN‑COOH@DOX fluorescence NVP. The HMSN co-delivery system was successfully synthesized with encapsulation efficiency of 37% (DOX) and 44% (NVP), and high PH-sensitive property was observed. The apoptosis rate of CD117+CD44+A2780 ovarian cancer stem-like cells treated by HMSN co-delivery system were almost 3 times higher than those of the free drugs group. The expression of Bax was significantly increased while Bcl-xl, and p-Akt reduced (P≤0.05). These data indicate that the co-delivery system demonstrated a high efficiency in promoting apoptosis in ovarian cancer stem-like cells by targeting IGF‑1R, but further study is still needed.
