  • Publication number: 20130028957
    Abstract: The present invention provides a pharmaceutical composition for treating cancer, comprising at least one selected from deoxyribonucleic acids (DNA) for encoding small interfering RNA (siRNA) which complementarily binds to the base sequence of the transcript (mRNA transcript) of the FLJ25416 gene, represented by sequence number 3, sequence number 5, and sequence number 7 to inhibit the intracellular expression of the FLJ25416 gene, antisense RNA which inhibits expression of the FLJ25416 gene, and short hairpin RNA (shRNA) which inhibits expression of the FLJ25416 gene. As the siRNA, which is complementary to the base sequence of the transcript (mRNA transcript) of the FLJ25416 gene, the antisense RNA, and the shRNA, according to the present invention, inhibit expression of the FLJ25416 gene which is known to be expressed in cancer cells, and thus kill cancer cells, the composition of the present invention can be used as a novel anti-cancer agent.

  • Publication number: 20110065176
    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.

  • Publication number: 20110008370
    Abstract: Provided are a composition for diagnosing cancer or screening an anticancer drug comprising an FLJ25416 gene or an antibody directed to a protein expressed from the FLJ25416 gene, a composition for treating cancer comprising an inhibitor of the gene or an inhibitor of the protein expressed from the gene and a pharmaceutically acceptable carrier, and a kit for diagnosing cancer comprising at least one of the FLJ25416 gene and the protein expressed from the FLJ25416 gene. The FLJ25416 gene is expressed at high level in specific cancer cells, and induces an increase in proliferation rate of normal cells. The expression of the gene is suppressed, which results in an inhibitory effect on cancer cell growth. Thus, the FLJ25416 gene can be used as a target gene for diagnosis or treatment of cancer.
