  • Patent number: 10640777
    Abstract: The present invention provides an antibody having cross-linking ability against human Sema3A and mouse Sema3A. The antibody of the present invention can be used as therapeutic antibody drugs for inhibiting Sema3A in various cancers in which Sema3A expression is high, such as glioblastoma, pancreatic cancer and liver cancer. Since Sema3A is considered to be a therapeutic target of diabetic retinopathy, autoimmune arthritis, neuropathic pain and osteoporosis, the antibody of the present invention or an antigen binding fragment thereof can be used as a therapeutic agent for associated diseases in addition to an anti-cancer drug. The antibody of the present invention inhibits the growth of cancer cells derived from various carcinomas through inhibition of Sema3A function due to high anti-Sema3A binding, and inhibits the movement of cancer cells through inhibition of phosphorylation of ERK among Sema3A lower signaling substances.

  • Patent number: 9062326
    Abstract: There is provided an expression vector for animal cell having an increased gene expression efficiency, and particularly, an expression vector for animal cells including a MAR element and a SAR element, which are gene expression increasing factors, at a 5? end of a promoter, a 3? end of a transcription termination site, or at both of the 5? end of the promoter and the 3? end of the transcription termination site. The expression vector for animal cells according to the present invention exhibits remarkably increased gene expression efficiency as compared to conventional expression vectors for animal cells, such that protein expression of foreign genes may be significantly increased using this expression vector for animal cells. Particularly, the expression vector for animal cells according to the present invention may be useful in that a high-expression cell line may be secured even without MTX amplification.

  • Patent number: 7259010
    Abstract: The present invention relates to mammalian expression vectors including nuclear matrix attachment region of human interferon ?, and more particularly to pPGM-1, pPGM-2 and pPGM-3 including nuclear matrix attachment region of interferon ? gene. Those expression vectors confer position independent expression of the introduced foreign gene, thus increasing the frequency of colonies which efficiently express the recombinant protein.
