ABSTRACT
Objective To explore the effects of adriamycin-loaded immuno-nanoparticles on multidrug resistance (MDR) of hepatoma cell line SMMC-7721/ADM. Methods The cytotoxicity of the adriamycin-loaded immuno-nanoparticles on the bepatoma cell line SMMC-7721/ADM in vitro and the tumor cell-binding ability of adriamycin-loaded immuno-nanoparticles were detected. Results The effect of the cytotoxicity of adriamycin-loaded immuno-nanoparticles on the hepatoma cell line SMMC-7721/ADM was significantly better than that of adriamycin-loaded nanoparticles. Adriamycin-loaded immuno-nanoparticles had the specific binding ability with the hepatoma cell line SMMC-7721/ADM. Conclusions Adriamycin-loaded immuno-nanoparticles can overcome the MDR of the tumor in vitro. The mechanism may be that immuno-nanoparticles could adhere to the tumor cell membrane, and the release of the loaded adriamycin creates a high local concentration in the extracellular medium. The increased concentration gradient improves the diffusion of adriamycin from the extracellular medium to the intracellular medium.
