Figure 5.

Flow cytometric analysis of the interaction between AC-GlcNAc-conjugated polyethyleneimine (PEI) and NF-κB decoy oligonucleotide (ODN) complexes and cervical cancer cells (HeLa cells), vimentin-deficient HeLa cells, and normal human dermal fibroblasts (NHDFs). (a) Flow cytometric charts of these interactions. (b) Mean fluorescent intensity of the interaction between these complexes and each cell type. Values are indicated based on fluorescence intensity of the negative control. Statistical analyses were performed by Student’s t-tests (n = 4–8, ** p < 0.01).
