Abstract:

The aim of this study is to evaluate newly developed radiopharmaceutical�??s (99mTc-MTX-CSNPs) incorporation to human breast cancer (MCF-7) and human keratinocyte (HaCaT) cell lines for breast cancer diagnosis. For this purpose, methotrexate (MTX) loaded chitosan nanoparticles (CSNPs) were prepared by ionic gelation process, stored for 6 months and evaluated in terms of particle size, PdI value and zeta potential. Produced MTX-CSNPs were radiolabeled by 99mTc with high labeling efficiency (>90%). Then, newly developed radiopharmaceutical�??s target/non-target ratio was investigated with cell culture studies by using MCF-7 and HaCaT cell lines. Results demonstrated that the incorporation of 99mTc-MTX-CSNPs in breast cancer cells was found about 2-times higher than normal cells. So, 99mTc-MTX-CSNPs might be used for human breast cancer diagnosis in nuclear medicine patients.
