RAGE-aptamer significantly reduced levels of 8-hydroxy-2'-deoxy-guanosine, AGEs, RAGE, proliferating nuclear antigen, cyclin D1, vascular endothelial growth factor (VEGF), monocyte chemoattractant protein-1 (MCP-1), and CD31 and Mac-3, respective markers of endothelial cells and macrophages in tumors of nude mice and suppressed the proliferation and liver metastasis of malignant melanoma.
Furthermore, knockdown of ATF3 attenuated subcutaneous tumor growth and CD31(+) neovasculature in xenograft assays with HT29 and CaCO2 cells and inhibited hepatic metastasis.
