Zusammenfassung:Methods of identifying specific target molecules for design of anti-angiogenic and vascular targeting approaches are disclosed. Transcriptional profiles of tumor endothelial cells were compared with that of normal resting endothelial cells, normal but angiogenically activated placental endothelial cells, and cultured endothelial cells. Although the majority of transcripts were classified as general angiogenesis markers, 17 genes were identified that show specific overexpression in tumor endothelium. Antibody targeting of four cell-surface expressed or secreted products (vimentin, CD59, HMGB1 and IGFBP7) inhibited angiogenesis in vitro and in vivo. Finally, targeting endothelial vimentin in a mouse tumor model significantly inhibited tumor growth and reduced microvessel density. The results demonstrate the utility of the identification and subsequent targeting of specific tumor endothelial markers for anticancer therapy.
