    Vývoj nové rekombinační technologie k transformaci chloroplastů a její využití pro produkci E7 proteinu lidského papilomaviru v rostlinách

  • Annotation in Czech

    Je navržen vývoj nové metody transformace chloroplastů využívající lineární DNA vektory aplikované biolisticky spolu s chloroplastovými kazetami exprimujícími rekombinační geny Red bakteriofága lambda. Idea vychází z pokusů o cílenou inserční mutageneziv kvasinkách, sinicích a E. coli, kde konce DNA podporují výrazně homologní rekombinaci a lambdové proteiny Exo, Beta a Gam velmi účinně chrání a upravují konce DNA, které pak i při velmi krátké homologii výrazně podporují rekombinaci. Lineární vektory mohou být připraveny jako produkty PCR reakce se syntetickými primery na koncích, homologními s cílovou sekvencí v chloroplastovém genomu. Chloroplastové vektory ponesou kromě markerových genů také onkogen E7 z lidského papilomaviru ve formě neonkogenní,ale vysoce immunogenní fuze E7GGG/GUS. Cilem je získat transformanty produkující antigen využitelný jako součást terapeutické vakciny. Virové antigeny produkované v rostlinách budou stanovovány protilátkami a testovány na myších.

Completed project evaluation

  • Provider evaluation

    U - Uspěl podle zadání (s publikovanými či patentovanými výsledky atd.)

  • Project results evaluation

    Tobacco and Chlamydomonas strains were prepared with chloroplasts transformed by semisynt. vectors carrying human papilloma virus E7 oncogen. Algal extracts were used for mice immunization where E7-antibodies were induced but not cytotoxic lymphocytes.
