Figure Lengend Snippet: HANPs increased the level of intracellular Ca 2+ , depolarized mitochondria membrane potential and promoted ROS production of the tumor cells. The relative intracellular Ca 2+ fluorescence intensity of 143B ( A ) and UMR106 ( B ) cells after the cells were treated with six HANPs at the concentration of 400 μg/mL for 1, 2 and 3 days. The representative CLSM images of 143B and UMR106 cells by JC-1 staining after the cells were treated with six HANPs at the concentration of 400 μg/mL for 3 days (n=3; after HANPs treatment, the corresponding red fluorescence (JC-1 aggregates) decreased, while the corresponding green fluorescence (JC-1 monomers) increased, indicating that mitochondrial depolarization occurred in tumor cells after HANPs treatments) ( C ). The relative ROS fluorescence intensity in 143B ( D ) and UMR106 ( E ) cells after the cells were treated with six HANPs at the concentration of 400 μg/mL for 1, 2 and 3 days (n=3; for 143B cells: vs control, *P<0.05,**P<0.01; vs R-HANPs-1, $ P<0.05, $$ P<0.01; for UMR106 cells: vs control, *P<0.05,**P<0.01; vs N-HANPs-1, ++ P<0.01; vs N-HANPs-2, & P<0.05, && P<0.01).
