NPS treatment of C3.43 cells results in significant upregulation of caspase 3/7 activity at lower treatment energies.

<p><b>(A)</b> Measured levels of activated caspase 3/7 in cells at 3h post NPS treatment for a range of NPS energy densities. Data shown as the mean of 4 experiments and the error bars represent the standard error of the mean (**p<0.01 ***p<0.001, One-way ANOVA followed by Dunnett’s multiple comparisons test to untreated cells). <b>(B)</b> Mean distribution of treated C3.43 tumor cells in early and late apoptosis at 3 h post-treatment with indicated NPS energy density <b>(C)</b> Data collected 24 h post NPS treatment.
