Figure 4. Effects of CE-CKC emulsions and cyclosporine A (CsA) on gene expression in HCE-2 cells following LPS stimulation. HCE-2 cells were preincubated for 30 min with cationic emulsions of cetalkonium chloride (CE-CKC) or dexamethasone (DXM). The cells were then stimulated with lipopolysaccharide (LPS) for 24 h. Emulsions were omitted during LPS stimulation, whereas CsA was present. Results are expressed as percentage of the unstimulated control (set at 100%). Experiments were performed in duplicates.
