Upregulation of vascular endothelial growth factor by hydrogen peroxide in human colon cancer

Figure 5 Measurement of nuclear and cytoplasmic NF-κB associated fluorescence by LSC. The red fluorescence represents the nuclear area, and the intensity of green fluorescence over nucleus(Fn) reflects NF-κB activity. A, B: LS174T cells without H₂O₂ treatment. C, D: Increase in NF-κB activity of LS174T cells with H₂O₂ exposure. E, F: HCT8 cells without H₂O₂ treatment. G, H: Increase in NF-κB activity of LS174T cells with H₂O₂ exposure.
