In this study, 2-amino-2-deoxy-glucose (2DG) was conjugated to COOH modified cobalt ferrite magnetic nanoparticles (COOH-MNPs), which were designed to target tumor cells as a potential targetable drug/gene delivery agent for cancer treatment. According to our results, it is apparent that, 2DG labeled MNPs were internalized more efficiently than COOH-MNPs under the same conditions in all cell types (MDA-MB-231 and MCF-7 cancer and MCF-10A normal breast cells) (p < 0.001). Moreover, the highest amount of uptake was observed in MDA-MB-231, followed by MCF-7 and normal MCF-10A cells for both MNPs. The apoptotic effects of 2DG-MNPs were further evaluated, and it was found that apoptosis was not induced at low concentrations of 2DG-MNPs in all cell types, whereas dramatic cell death was observed at higher concentrations. In addition, the gene expression levels of four drug-metabolizing enzymes, two Phase I (CYP1A1, CYP1B1) and two Phase II (GSTM3, GSTZ1) were also increased with the high concentrations of 2DG-MNPs.

© 2022 Wiley-VCH GmbH.Development of targeted nanoparticles as carriers to deliver photosensitizers to cancer cells is highly beneficial for ensuring the expected therapeutic outcome of photodynamic therapy. Herein, polyacrylic acid (PAA) coated superparamagnetic iron oxide nanoparticles (SPIONs), conjugated with endothelial growth factor receptor (EGFR) targeting Cetuximab (Cet) were loaded with a BODIPY-based (BOD-Se-I) photosensitizer (Cet-PAA@SPION/BOD-Se-I) to achieve enhanced and selective photodynami...
Targeted delivery of CPG-oligodeoxynucleotide to breast cancer cells by poly-amidoamine dendrimer-modified magnetic nanoparticles
Taghavi Pourianazar, Negar; Gündüz, Ufuk; Gündüz, Güngör; Department of Biotechnology (2016)
One major application of nanotechnology in cancer treatment involves designing nanoparticles to deliver drugs, oligonucleotides, and genes to cancer cells. Nanoparticles should be engineered so that they could target and destroy tumor cells with minimal damage to healthy tissues. This research aims to develop an appropriate and efficient nanocarrier, having the ability of interacting with and delivering CpG-oligodeoxynucleotides (CpG-ODNs) to tumor cells. CpG-ODNs activate Toll-like receptor 9 (TLR9), which...

In this study, strong magnetic featured silica coated Cobalt ferrite (CoFe204) nanoparticles were labeled with 2-deoxy glucose (2-DG) for better targetting to cancer cells and the molecular effects of these prepared magnetic nanoparticles (MNPs) were investigated in cancer cell lines. In this study, in vitro characterization of 2-DG labelled MNPs were carried out in breast cancer cells (MDA-MB-231 breast cancer and normal cell MCF10A), and cellular uptake mechanisms, genotoxicity, intracellular levels of ox...

Khodadust, Rouhollah; Unsoy, Gozde; Gündüz, Ufuk (2014-10-01)
The objective of this study was to develop and evaluate the anticancer activity and the safety of a combinational drug delivery system using polyamidoamine (PAMAM) dendrimer-coated iron oxide nanoparticles for doxorubicin and poly I:C delivery in vitro. Dendrimer-coated magnetic nanoparticles (DcMNPs) are suitable for drug delivery system as nanocarriers with their following properties, such as surface functional groups, symmetry perfection, internal cavities, nano-size and magnetization. These nanoparticle...
