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: 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.
