Abstract

Background Nano-therapy exhibit the potential of revolutionizing cancer therapy. This field introduces nanovectors/nanocarriers for anticancer drugs targeted delivery, and also finds application in imaging. Chrysin, a natural flavonoid, was recently studied as having important biological roles in chemical defenses, nitrogen fixation, anti-inflammatory, and anti-oxidant properties. We aim at studying the effect of nano-chrysin on breast cancer cell line. Methods The effect of chrysin loaded PCL-PEG-PCL was studied on T47D breast cancer cell line. The structure and drug-loading of chrysin were characterized using 1H NMR, FT-IR and SEM. The in vitro cytotoxicity of pure and nano-chrysin was tested by the MTT assay. Gene expression of FTO, hTERT, and BRCA1 were evaluated using Real-time PCR. Results Data analysis from MTT assay showed that chrysin has a time-dependent cytotoxic effect on T47D cell line. Furthermore, the results of Real-time PCR suggested that encapsulated chrysin have higher antitumor effect on gene expression of FTO, BRCA1 and hTERT than free chrysin. Conclusion Combined nano-chrysin therapy will not only improve cancer cell cytotoxicity, but also be a complementary and potential complex in breast cancer therapy. © 2016
