Magnetic Nanomedicine for CD133-Expressing Cancer Therapy Using Locoregional Hyperthermia Combined with Chemotherapy

Abstract

Aim: Cells with CD133 overexpression, a theoretical cancer stem cells (CSCs) marker, have been shown to induce colorectal cancer (CRC) initiation and relapse. Therefore, the detection and treatment of CSCs are the most important factors in overcoming CRC. Materials & methods: Herein, we developed a magnetite-based nanomedicine (superparamagnetic iron oxide@poly(sodium styrene sulfonate)/irinotecan/human serum albumin-anti-CD133 nanoparticle) using loco-regional hyperthermia combined with chemotherapy for CRC- and CSC-specific targeting treatment. Results: The designed nanoparticles were highly biocompatible and exhibited a higher temperature increase rate under radiofrequency generator irradiation. The nanoparticles could be used as a T2-weighted magnetic resonance imaging contrast media, and also applied during hyperthermia and chemotherapy to display a synergistic anticancer effect. Conclusion: Therefore, the superparamagnetic iron oxide@poly(sodium styrene sulfonate)/irinotecan/human serum albumin-anti-CD133 nanoparticles are a powerful candidate for future antitumor strategies.
