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.

The present invention provides diagnostic methods for predicting the effectiveness of treatment of an hepatocellular carcinoma (HCC) patient with an IGF-1R kinase inhibitor by assessing whether the HCC tumor cells express a high level of AFP, or whether serum levels of AFP protein are high. The present invention also provides diagnostic methods for predicting the effectiveness of treatment of cancer patients with IGF-1R kinase inhibitors, based on a determination of the expression level of IR, IGF-2, IGFBP3 or IGFBP7 in tumor cells, or a 4-gene index calculated using the expression vales for each of these four genes, which can be used to identify tumors that will be sensitive to IGF-1R kinase inhibitors, and also those that will be insensitive. Improved methods for treating cancer patients with IGF-1R kinase inhibitors that incorporate the above methods are also provided.

The invention provides mutain of a human insulin-like growth factor conjugated protein 7 (IGFBP7). The mutain contains mutation of Arg198Ile/His200Phe, and has an amino acid sequence of SEQ ID NO.1. An igfbp7 gene coding sequence is selected from an SW480cDNA library of a human colorectal cancer cell line and is constructed into pET28a plasmids of a prokaryotic expression vector, so that the IGFBP7 protein can be expressed in a colon bacillus strain BL21. On the basis of the expression vector, mutain of the IGFBP7 is constructed, BL21 is converted, the mutain is expressed and purified, and a key site where the IGFBP7 is bonded with insulin is pointed out. The mutain provided by the invention has simple steps in a preparation method and high success rate, and the bonding capacity of the protein with insulin is remarkably reduced, so that insulin resistance can be suppressed and the mutain can be applied to the preparation of a medicament for treating type 2 diabetes.
