  • Patent number: 9879281
    Abstract: Disclosed herein is a novel recombinant virus vector derived from the attenuated vaccinia virus strain KVAC103. The recombinant virus vector is obtained by inserting an exogenous gene into the KVAC103 and may be used as a safe vaccine delivery vehicle in mammals. Particularly, recombinant viruses obtained by rescuing some of the genes deleted from the parent virus have an enhanced ability to proliferate in cells being cultured, and thus are easily produced. In addition, the recombinant viruses express an increased level of an exogenous antigen, and thus has enhanced immunogenic efficacy. Such recombinant virus vectors may be used in vaccines for preventing diseases, therapeutic vaccines, and molecular biological studies.

  • Patent number: 9879232
    Abstract: The attenuated vaccinia virus strain KVAC103 was obtained by subculturing a vaccinia virus strain 103 times in VERO cells. The attenuated vaccinia virus strain KVAC103 has significantly low toxicity, shows reduced skin lesions, and, at the same time, induces effectively immune responses to poxvirus. Thus, it can be used as a poxvirus vaccine while causing less side effects.

  • Patent number: 8835164
    Abstract: Disclosed are a cell line that expresses protein of Seq. No. 1, and a method for screening an anticancer compound of uterine cervical cancer by using the same. The stable cell line that expresses oncoprotein E6 of a human papillomavirus type 16 variant strain is used to determine a difference in amounts of expression of tumor suppressor genes, such as p53, between E6 protein of the reference strain and E6 protein of a variant strain, thereby screening an anticancer compound of uterine cervical cancer, etc. Further, it is possible to develop an anticancer agent of uterine cervical cancer.

  • Publication number: 20140186357
    Abstract: A treatment method for degenerative brain disorders using a pharmaceutically effective dose of the inhibitor of SUMO1 (small ubiquitin-like modifier 1) and BACE1 (?-secretase) interaction, or the inhibitor of SUMO1 expression or activation is provided. More specifically, it was confirmed that SUMO1 increased BACE1 accumulation and A? generation, that is SUMO1 regulated BACE1 accumulation by interacting with BACE1, and BACE1 dileucine motif was involved in SUMO1-mediated BACE1 accumulation. In addition, SUMO1 protein induced autophagy in H4 cells, while SUMO1 depletion reduced LC3-II level. It was further confirmed that SUMO1 and LC3 were co-localized in the cortex of APP transgenic mice. As shown herein, a pharmaceutically effective dose of the inhibitor of SUMO1 and BACE1 interaction or the inhibitor of SUMO1 expression can be effectively used for the treatment of degenerative brain disorders.

  • Patent number: 8679768
    Abstract: The present inventors screened peptides having a specific sequence specifically binding to amyloid-beta antibody and accordingly confirmed that A?22(pE)-42 peptide showed higher reactivity to amyloid-beta antibody in serum of Alzheimer's disease patients. Therefore, the said A?22(pE)-42 peptide can be used as an active ingredient for the kit for diagnosing dementia and thus it can be said that the peptide can be effectively used for the diagnosis of dementia whose early diagnosis is hardly possible.

  • Patent number: 8519108
    Abstract: The method of the present invention comprising successive column chromatography processes for the purification of an anthrax protective antigen can achieve an improved purity of the anthrax protective antigen product by effectively removing impurities (e.g., cellular residual proteins in the culture solution) without the loss of anthrax protective antigen. Therefore, the method of the present invention can be advantageously used for economically producing the anthrax protective antigen on a large scale.

  • Publication number: 20130089536
    Abstract: The present invention relates to a GCP II (glutamate carboxypeptidase II) mutant (K699S) having the activity of inhibiting glutamate production and the activity of cleavaging ?-amyloid, and to a pharmaceutical composition for the prevention and treatment of a disease selected from the group consisting of amyloidosis, Alzheimer's disease, Down syndrome accompanying Alzheimer's disease, stroke, dementia, Huntington's disease, Pick's disease, and Creutzfeldt-Jakob disease comprising the GCP II mutant (K699S) as an active ingredient. The GCP II (glutamate carboxypeptidase II) mutant (K699S) demonstrates not only excellent A? cleavage activity compared with the wild type GCP II but also excellent activity of inhibiting glutamate production, unlike the wild type GCP II, so that the mutant has been confirmed to have higher effect and stability than the wild type, suggesting that the GCP II mutant can be effectively used for the prevention or treatment of neurodegenerative diseases.
