Bioengineered nCAR/miR-34a-5p induces apoptosis in ES cells. (A) The apoptotic profiles were evaluated by flow cytometric analysis after Annexin V-FITC/PI staining. (B) Comparison of the percentages of apoptotic cells with different treatments showed that bioengineered nCAR/miR-34a-5p largely induced apoptosis (P < 0.0001, two-way ANOVA). (C–D) Immunofluorescence assessment of apoptotic biomarker cleaved-casepase-3 in ES A673 cells further confirmed the effect of bioengineered nCAR/miR-34a-5p on apoptosis, which was quantitated as over 100% increase in the number of cleaved-caspase-3-positive cells treated with nCAR/miR-34a-5p, as compared to either control RNA or vehicle treatment (P < 0.01, one-way ANOVA). Values are mean ± SD of triplicate treatments. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
