Abstract:

Despite the broad anticancer activity, whereas the clinical application of luteolin is hindered by unsatisfactory water solubility and non-targeting. Herein, targeted inhibitory effects of luteolin-loading HER2 nanospheres (Her-2-NPs) were successfully prepared by thin film ultrasonic method. In comparison with the non-targeted nanospheres, Her-2 nanospheres could significantly boost the intake of luteolin in SK-BR-3 cells. The proliferation and apoptosis of breast cancer cells were detected by MTT testing and flow cytometry examination, respectively. Consequently, the expressions of FOXO1 mRNA level was detected using qPCR assay and protein level was detected using Westernblot. We discovered that Luteolin-loading Her-2 nanospheres could significantly hinder the proliferation of breast cancer cells, down-regulation their migration, and up-regulation FOXO1 expression at mRNA and protein levels, reveal a mechanism whereby luteolin interferes with breast cancer. Collectively, these results suggest Her-2-modified nanospheres increases the efficiency of luteolin uptake and thus improves the treatment benefit of breast cancer.
