Özet
Gold nanoparticles (GNPs) tagged with peptides are pioneers in bioengineered cancer therapy. The aim of the current work was to elucidate the potential anticancer interactions between doxorubicin and GNPs loaded with tumor necrosis factor-alpha (TNF-?). To investigate whether GNPs loaded with TNF and doxorubicin could stimulate autophagy and apoptosis in breast cancer cells. Two human breast cancer cell lines, MCF-7 and AMJ-13, as well as different apoptotic and autophagy markers, were used. In both cell types, treatment with TNF-loaded GNPs in conjunction with doxorubicin increased the production of apoptotic proteins including Bad, caspase-3, caspase-7, and p53 with upregulation of the LC3-II and Beclin1 proteins. In addition, the findings showed that the mitogen-activated protein kinase signaling pathway was dramatically affected by the GNPs loaded with TNF-? and combined with doxorubicin. This had the effect of decreasing p-AKT while simultaneously increasing p-JNK1/2. The findings demonstrated that GNPs loaded with TNF-? and combined with doxorubicin can induce both autophagy and apoptosis in breast cancer cells. These results suggest that TNF- and doxorubicin-loaded GNPs provide a therapeutic option as a nanomedicine to inhibit the proliferation of breast cancer.
