    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.
