Özet
Aim: Breast cancer is the most common frequently diagnosed malignancy among women and leading cause of cancer death in
women worldwide. The aim of this study is 1) to increase the biocompatibility of the titanium dioxide (TiO�) nanoparticles (NPs)
by coating it with PolyEthylene Glycol (PEG) and to develop a new nanostructure system and 2) to determine anticancer activity of
doxorubicin (DOX) loaded PEG-TiO� on MDA-MB-231 cell lines.
Material and Methods: TiO� nanoparticles used in this study were synthesized, coated with PEG, and PEG-TiO� nanostructure system
was loaded by DOX. UV analysis was performed on the prepared solutions. The synthesized drugs were applied to the MDA-MB-231
breast cancer cell line and cytotoxic effect of these drugs were determined by using MTT method. The MDA-MB-231 cells were
treated with different concentrations of TiO� (5-100 μg/ml) for 24, 48 and 72 hours. Apoptosis and necrosis were determined by
fluorescence microscopy using the Hoechst 33258 (HO) /propidium iodide (PI) double staining.
Results: The effects of TiO�, PEG-TiO�, DOX, and TiO�-PEG-DOX on the MDA-MB-231 cell line were compared with the control group
and IC50 values were determined for 24, 48 and 72 hours.
Conclusion: In this study, it was shown that the effect of TiO�-PEG-DOX nanostructured system on MDA-MB-231 cell line was
inhibition growth in cancer cells and induction of apoptosis when compared with control group and DOX.
