Abstract: The present invention relates to a humanized scFv delivery vehicle targeted to be human T-cell specific, and provides: a humanized scFv which comprises a heavy-chain variable region (VH) consisting of a polypeptide comprising an amino acid sequence given by sequence number 32 and comprises a light-chain variable region (VL) consisting of a polypeptide comprising an amino acid sequence given by sequence number 34; and a T-cell-specific drug or marker delivery vehicle comprising the humanized scFv. The humanized scFv of the present invention has minimalised antigenicity and has an effect which does not give rise to an immune reaction even when used in the human body, and thus can advantageously be used as a delivery vehicle for specifically delivering a target substance such as a siRNA gene or an immune reaction regulating protein to T-cells.

Abstract: The present invention relates to a fusion protein resulting from the fusion of a cancer-specific antibody and an angiogenesis inhibitor, and relates to an anti-cancer composition including the same. More specifically, in the present invention, it is preferable that the cancer-specific antibody is trastuzumab or a fragment thereof, and the angiogenesis inhibitor is a VEGF-Trap. When the fusion protein according to the present invention is used, there are advantages in that angiogenesis and cancer cell growth can be effectively inhibited as compared to trastuzumab or VEGF-Trap, and side effects can also be reduced.

Abstract: The present invention relates to an anticancer agent containing a TMPRSS4 (transmembrane protease, serine 4) inhibitor as an effective ingredient, more precisely an anticancer agent containing an inhibitor of TMPRSS4 activity as an effective ingredient. The anticancer agent of the present invention can be used effectively for the treatment of cancer by inhibiting TMPRSS4 expression in cancer cells and thereby inhibiting cancer cell invasion and cancer cell growth.

Abstract: A humanized antibody is produced by process comprising the steps of: (a) selecting a specificity determining residue (SDR) of the complementarity determining region (CDR) of murine monoclonal antibody heavy chain and light chain variable regions; and (b) grafting said SDR to at least one of the corresponding amino acid sequences in human antibody variable regions.

Abstract: Disclosed herein are a pharmaceutical composition for inhibiting the growth or metastasis of cholangiocarcinoma, comprising a L1CAM activity inhibitor or expression suppressor and a treatment method using the composition. This is based on the finding that L1CAM is overexpressed on cholangiocarcinoma and plays an important role in the growth and metastasis of cholangiocarcinoma and the mortality of cholangiocarcinoma patients increases as the expression rate of L1CAM increases. Also, antibodies inhibitory of the activity of L1CAM, or siRNAs suppressing the expression of L1CAM, are found to reduce the growth and invasion of cholangiocarcinoma cells. Mouse monoclonal antibodies, recognizing the L1CAM protein on the cholangiocarcinoma cell surface and binding specifically to cholangiocarcinoma tissues, or siRNAs, antisense oligonucleotides or shRNAs, may be useful in the treatment of cholangiocarcinoma by inhibiting the growth, invasion and migration of cholangiocarcinoma cell.

Abstract: The present invention relates to humanized antibodies specific to a tumor-associated glycoprotein, TAG-72, and anticancer compositions comprising the humanized antibodies. In detail, the present invention relates to a humanized antibody which has enhanced antigen binding affinity by mutating a heavy chain of a humanized antibody PXA/HzK specific for TAG-72, an antibody which is prepared by replacing a light chain of the humanized antibody with a human light chain, and anticancer compositions including the antibodies.
