Summary: | The invention relates to biotechnology, in particular to genetic engineering, and constitutes a comprehensive promoter (alternatives) which is active in more than three types of cancer cells of varying etiology, said promoter being more active than a native promoter of the BIRC5 gene and comprising a combination of recognition sites of transcription factor proteins, said combination being changed or extended in comparison to the initial promoters. The invention also relates to an expression vector comprising said promoter, to a method for selective killing of cancer cells but not of normal cells, resulting in toxin synthesis within the cancer cells with the use of the promoter, and also to a method for treating cancer in mammals by introducing an animal vector. The invention makes it possible to direct enzyme and cytokine synthesis with the use of the promoter according to the invention in such a manner that a prodrug which is deliverable externally is converted into a toxin, and to activate the cells of the immune system.
L'invention concerne la biotechnologie et notamment le génie génétique et porte sur un promoteur à profils multiples (et variantes), actif dans plus de trois types de cellules cancéreuses d'étiologies différentes et possédant une activité supérieure que le promoteur natif du gène BIRC5 et comprenant un ensemble élargi ou modifié par rapport aux promoteurs initiaux de sites de reconnaissance de protéines facteurs de transcription. L'invention concerne également un vecteur d'expression qui comprend ce promoteur, un procédé de suppression sélective de cellules cancéreuses mais pas de cellules normales, qui provoque la synthèse dans les cellules cancéreuses d'une toxine utilisant le promoteur ainsi qu'un procédé de traitement du cancer chez les mammifères par l'administration à l'animal dudit vecteur. L'invention permet de diriger la synthèse du ferment et de cytokine utilisant le promoteur selon l'invention de manière à ce que le promédicament fourni de l'extérieur se transforme en une toxine, et d'activer les cellules du système immunitaire. |
