ABSTRACT
Objective To explore the mechanism that gold nanorods trigger apoptosis in cancer cells.Methods Gold nanorods was synthesized by gold seed growing method, and its characterization was detected; gold nanorods on cell proliferation-toxicity were evaluated by CCK-8 Kit and apoptosis were detected by flow; mitochondrial membrane potential were tested by JC-1 and activation of Caspase 9 and Caspase 3 were detected by western blot. Results The results found that gold nanorods had nontoxic to normal cells, but highly toxic to tumor cells; and with the increasing of gold nanorods’ working time, the percentage of apoptotic cancer cells was increasing; in addition to, normal cells’ mitochondrial membrane potential did not change, but cancer cells had a significant reduction in mitochondrial membrane potential.Conclusion This study proves that gold nanorods induce apoptosis through the mitochondrial apoptosis pathway.
