چکیده انگلیسی
Targeted therapy is an emerging technique in cancer detection and treatment. This paper presents the results of a combined experimental and theoretical study of the specific targeting and entry of luteinizing hormone releasing hormone (LHRH)-conjugated PEG-coated magnetite nanoparticles into triple negative breast cancer (TNBC) cells and normal breast cells. The conjugated nanoparticles structures, cellular uptake of PEG-coated magnetite nanoparticles (MNPs) and LHRH-conjugated PEG-coated magnetite nanoparticles (LHRH-MNPs) into breast cancer cells and normal breast cells were investigated using a combination of transmission electron microscope, optical and confocal fluorescence microscopy techniques. The results show that the presence of LHRH enhances the uptake of LHRH-MNPs into TNBC cells. Nanoparticle entry into breast cancer cells is also studied using a combination of thermodynamics and kinetics models. The trends in the predicted nanoparticle entry times (into TNBC cells) and the size ranges of the engulfed nanoparticles (within the TNBC cells) are shown to be consistent with experimental observations. The implications of the results are then discussed for the specific targeting of TNBCs with LHRH-conjugated PEG-coated magnetite nanoparticles for the early detection and treatment of TNBC.
