Abstract:
PURPOSE: Provided is a preparation of infectious HCV-like particles which are characteristically used as antigens for the detection HCV vaccine or HCV antibodies and for the inspection or examination of infection inhibiting drugs. CONSTITUTION: The preparation of infectious HCV-like particles is characterized by using a recombinant alphavirus expression vector(KCCM-10287) and a helper vector(KCCM-10286) which express HCV core, E1 and E2.

Abstract:
PURPOSE: An Alphavirus expression vector capable of expressing a cancer-inhibiting protein, its producing method and its use are provided, thereby effectively inhibiting and preventing the growth of a cancer cell. CONSTITUTION: The Alphavirus expression vector capable of expressing a cancer-inhibiting protein contains a first cancer-inhibiting gene which is operably linked under operation of a first subgenomic promoter, a second cancer-inhibiting gene which is operably linked under operation of a second subgenomic promoter, and a third cancer-inhibiting gene which is operably linked under operation of a third subgenomic promoter, in which the cancer-inhibiting gene is selected from pRb/p110 or its homologue p107 and p120, p53 protein, p21 protein, p21 protein(WAF-1), bak, BRCA1, BRCA2, PTEN, APC, DCC, NF-1, NF-2, WT-1, MEN-I, MEN-II, zac1, p73, VHL, FCC and MCC; and the Alphavirus is Sindbis virus or Semliki Forest virus(SFV).
Abstract:
PURPOSE: Provided is HIV like particle which is composed of HIV-1 Gag, Env, Pol and/or Pro proteins expressed by an expression vector containing HIV-1 env, gag, pro, pol genes. The HIV like particle can be used as an antigen in a diagnosis kit of HIV infection and for HIV vaccine composition. CONSTITUTION: Alphavirus based expression vectors contain HIV-1 env, gag, pro and pol genes and they are as follows: pSFV/env-gag, pSFV/gag-env, pSFV/env-gag-pro, pSFV/env-gag-gagpro, pSFV/env-gag-gagΔpro, and pSFV/gagpol-env. The expression vectors further contains CTE(constitutive transport element) gene and they are as follows: pSFV/env-gag-gagpro-CTE, pSFV/env-gag-gagΔpro-CTE, pSFV/gagpol-env-MCTE, and pSF/gag-env-MCTE. HIV-like particle is manufactured by introducing one of the above vectors or its RNA transcript into an animal cell then expressing it.

Abstract:
PURPOSE: Alphavirus-based expression vectors expressing tumor suppressor proteins, a method for preparing the same and the use thereof are provided, thereby simultaneously expressing various tumor suppressor proteins, and consequently suppressing tumor effectively. CONSTITUTION: The alphavirus-based expression vector expressing tumor suppressor proteins comprises a first tumor suppressing gene or angiogenesis suppressing gene which is operably linked to a first subgenomic promoter; a second tumor suppressing gene or angiogenesis suppressing gene which is operably linked to a second subgenomic promoter; and a third tumor suppressing gene or angiogenesis suppressing gene which is operably linked to a third subgenomic promoter, wherein the first, second and third tumor suppressing genes or angiogenesis suppressing genes are the same or different; the tumor suppressing gene is p53 gene or PTEN gene; the antigiogenesis suppressing gene is angiostatin gene; and the alphavirus-based expression vector expresses tumor suppressor proteins Semliki forest virus(SFV) and Sindbis virus.
