Abstract: The present invention relates to human monoclonal antibodies neutralizing vascular endothelial growth factor receptor and the use thereof. More specifically, relates to human ScFv molecules neutralizing vascular endothelial growth factor receptor, and a composition for inhibiting angiogenesis and a composition for treating cancer, which contain the human ScFv molecules. The disclosed monoclonal antibody neutralizing vascular endothelial growth factor receptor shows excellent neutralizing ability in living cells, compared to that of a commercially available antibody against vascular endothelial growth factor receptor, and shows the ability to neutralize vascular endothelial growth factor receptor not only in humans, but also in mice and rats. Thus, the monoclonal antibody will be useful in anticancer studies and will be highly effective in cancer treatment.

Abstract: The present invention relates to a method for screening anticancer agent or SIP1/ZEB2 inhibitor using integrin alpha 5 (ITGA5), more precisely a method for measuring integrin alpha 5 expression pattern in SIP1/ZEB2 over-expressing cell line or SIP1/ZEB2 expression induced cell line, both treated with sample compounds, by comparing with that of the control. The method of the present invention facilitates screening of anticancer agent or SIP1/ZEB2 inhibitor simply by measuring integrin alpha 5 expression, so that it can be effectively applied in the field of medicine.

Abstract: The present invention relates to: a dual targeting antibody of a novel form having a water-soluble ligand fused to the N-terminus of a heavy chain or light chain of an antibody; a DNA encoding the dual targeting antibody; a recombinant expression vector containing the DNA; a host cell which is transformed with the recombinant expression vector; a method for preparing the dual targeting antibody by culturing the host cell; and a pharmaceutical composition including the dual targeting antibody.

Abstract: The present invention relates to humanized monoclonal antibodies LB-00503 and LB-00506, which are specific for human 4-1BB molecules, have high binding affinities and can bind efficiently with activated T cells expressing the 4-1BB molecule, as well as pharmaceutical compositions. Particularly, the present invention provides said humanized antibody LB-00503, which is modified from the humanized antibody Hz4B4-2 and substitutes the 61st amino acid, serine by asparagine in the amino acid residues of 59th˜61st and said humanized antibody LB-00506, which enhances the antibody binding affinity of said humanized antibody LB-00503 in which 2 amino acid residues of the right border in the antibody binding site CDR2 of the heavy chain variable region are substituted from glutamine (Q)—glycine (G) to lysine (K)—serine (S).
