Proliferation-Related Activity in Endothelial Cells Is Enhanced by Micropower Plasma

Figure 7

H₂O₂ generated by the micropower plasma is required for activation of NF-κB in the HUVECs. (a) Percentage of nuclear translocation of NF-κB in the cells treated with the micropower plasma or 15 μM H₂O₂ for 300 s. The data shown were represented as mean ± SD for at least 55 cells. The plasma treatment resulted in a significant increase in the nuclear translocation of NF-κB in the cells ( versus control and treatment of H₂O₂). (b) Percentage of nuclear translocation of NF-κB in the cells treated with the micropower plasma with/without 50 unit/mL catalase. The data shown were represented as mean ± SD for at least 57 cells. No difference in the percentage of nuclear translocation of NF-κB was observed between the nontreated and the plasma-treated conditions when H₂O₂ was decomposed by using catalase.
