    摘要: A recombinant expression vector, comprising extracellular soluble domain genes of DLK1 and IgG antibody Fc domain genes, is constructed, and DLK1-Fc fusion protein is expressed and purified at 293E cell. The invention confirmed the efficacy as a drug for inhibiting cancer metastasis by confirming markedly reduced migration of cancer cells by DLK1-Fc fusion protein and also computing pharmacokinetic parameters. DLK1-Fc fusion protein has relatively higher stability than non-fusion protein, significantly reduces migration of various cancer cell lines, and provides superior cancer metastasis inhibition effect even at small concentration. Accordingly, DLK1-Fc fusion protein can be used efficaciously as an effective ingredient of a composition for inhibiting cancer metastasis.

    摘要: The present invention relates to a novel endocytic motif, and in particular, to a fusion polypeptide including the motif represented by an amino acid sequence of SEQ ID NO. 1 and a protein transduction domain, a pharmaceutical composition for preventing or treating cancer including the same, and a method for treating cancer including the step of administering the composition. The present invention shows the effects of suppressing metastasis, infiltration, angiogenesis, and growth of cancer by specifically inhibiting c-Met endocytosis and effectively inhibiting HGF/c-Met signaling pathway associated with metastasis and growth of various types of cancer cells. Therefore, the present invention can be applied to an anticancer agent for various types of cancer.
