Targeting the transcription of a toxin gene to activated endothelial cells might be used for inhibiting angiogenesis in solid tumors. As a model, we transiently transfected human endothelial cells (HUVEC) in culture with expression plasmids for the toxic A-chain of diphtheria toxin (DT-A), using electroporation (achieving ≈70% transfection efficiency). Protein synthesis in HUVEC was highly sensitive to DT-A expression from constitutive viral promoters. E-selectin is strongly expressed on HUVEC activated by TNF
α or TPA. We therefore tested a human E-selectin promoter (−547 to +33) for targeting transcription of DT-A or reporter genes to HUVEC. Luciferase reporters were efficiently expressed in HUVEC from this promoter, with or without an enhancer responsive to Ets-1. Expression was increased by TNF α or TPA. DT-A showed highly preferential expression (increased by TNF α or TPA) in HUVEC, compared with WI38 human fibroblasts. HUVEC expressing DT-A were killed via apoptosis. Overall expression levels were influenced by alternative ‘backbone’ sequences used in the expression plasmids. We propose that delivery of transcriptionally regulated expression plasmids for DT-A in vivo, using cationic lipids that show preferential accumulation in activated or proliferating endothelium, may offer a novel means of inhibiting undesired angiogenesis. diphtheria toxin endothelial cells E-selectin promoter transcription References
