Influence of FOXP3 Knockdown on the proliferation, DNA synthesis and apoptosis of human SSC line. (A) Fluorescence microscope and phase-contrast microscope revealed transfection efficiency of FOXP3-siRNAs using the FAM-labeled miRNA oligonucleotides. Scale bars = 40 μm. (B) Western blots showed the protein changes of FOXP3 by FOXP3-siRNAs in human SSC line. (C) Real-time PCR displayed the mRNA changes of FOXP3 by FOXP3-siRNAs in human SSC line. (D) EDU incorporation assay showed the percentages of EDU-positive cells affected by control siRNA, FOXP3-siRNA 1 and FOXP3-siRNA 3 in human SSC line. Scale bars = 40 μm. Values are means ± SD from three independent experiments. (E) CCK-8 assay demonstrated the proliferation of human SSC line after transfection with FOXP3-siRNA 1 and FOXP3-siRNA 3. (F–G) Annexin-V/PI staining and flow cytometry displayed the percentages of early apoptosis and late apoptosis of human SSC line transfected with FOXP3-siRNA 1 and control siRNA. All values are means ± SD from three independent experiments. * indicated statistical significance (p<0.05) between FOXP3-siRNAs and control siRNA treatments. All experiments were repeated for at least three times.
