Recombinant plasmid DNA variation of clostridium oncolyticum — model experiments of cancerostatic gene transfer

The specific germinating capacity of spores of Clostridium oncolyticum in tumours in vivo, and various reports on concomitant partial oncolysis (tumour lysis) have prompted us to propose a concept of equipping C. oncolyticum with genes of other organisms producing cancerostatics.

description The specific germinating capacity of spores of Clostridium oncolyticum in tumours in vivo, and various reports on concomitant partial oncolysis (tumour lysis) have prompted us to propose a concept of equipping C. oncolyticum with genes of other organisms producing cancerostatics. As an example we used Colicin E3, whose structural genes lies in the E. coli plasmid pColE3-CA38. After in vitro recombination of restrictase EcoRI-fragmented pCo-lE3-CA38 DNA with an uncharacterized plasmid fraction from C. concolyticum a plasmidfree strain of C. oncolyticum was infected with recombinant DNA. A special microbiological selection system allows the identification of C. oncolyticum clones with Colicin E3-similar formation of cleared haloes. Die spezifische Keimfähigkeit von Sporen von Clostridium oncolyticum in Tumoren in vivo, sowie verschiedene Berichte über eine dadurch ausgelöste partielle Onkolyse (Tumorlyse) werden zum Anlaß genommen, ein Konzept zur Ausstattung von C. oncolyticum mit Cancerostatica-produzierenden Genen anderer Organismen vorzuschlagen. Als Beispiel wird Colicin E3 verwendet, dessen Strukturgen im E. coli Plasmid pColE3-CA38 liegt. Nach in vitro Rekombination von Restrictase Eco Rl-fragmentierter pColE3-CA38 DNS mit einer uncharakterisierten Plasmid-Fraktion aus C. oncolyticum wird ein Plasmid-freier Stamm von C. oncolyticum mit der Rekombinanten-DNS infiziert. Ein spezielles mikrobiologisches Selektionssystem erlaubt die Identifizierung von C. oncolyticum Klonen mit Colicin E3-ähnlicher Hemmhofbildung.
