摘要

The aim of this study was to look for a new medicine in diagnosing and treating of glioblastoma. Radioiodine-labeled anti-epidermal growth factor receptor (EGFR) binding nanoparticles were constructed. In vitro cell-binding assays were confirmed by confocal microscopy and flow cytometry. Cell cytotoxicity assays were evaluated by MTT assay; radionuclide uptake assays were performed by gamma-counter. Radioiodine-imaging studies were conducted using a xenograft nude mouse model in vivo. The results showed that EGFR significantly enhanced the uptake and accumulation of BSA-PCL in the experimental model of xenografts in nude mice, suggesting improved specific nanoparticle-based delivery. In conclusion, the data showed I-131-EGFR-BSA-PCL leading radioiodine therapy for U251 and U87 cells had a good effect in vitro and in vivo. Thus, I-131-EGFR-BSA-PCL may provide a new method for glioblastoma treatment.
