EGFR-targeted micelles containing near-infrared dye for enhanced photothermal therapy in colorectal cancer.


PMID 28445743

Abstract

The purpose of this research was to investigate the effectiveness of epidermal growth factor receptor (EGFR) targeted micelles loaded with IR-780 (Cetuximab/IR-780/micelles) for generating tumor targeting, multimodal images, and photothermal therapy (PTT). We initially studied the cellular uptake of these micelles using the HCT-116 and SW-620 cell lines. HCT-116 (high expression of EGFR) and SW-620 (low expression of EGFR) cell lines were used to examine biodistribution and antitumor effects of Cetuximab/IR-780/micelles. Time-lapse near-IR fluorescence (NIRF) images also indicated the highest IR-780 accumulation from Cetuximab/IR-780/micelles in HCT-116 tumors (p<0.05). HCT-116 tumors in tumor-bearing mice exhibited significantly higher accumulations of Cetuximab/IR-780/
