  • Patent number: 9816083
    Abstract: The current invention discloses a genetically engineered bacterium used for the treatment of breast cancer. The said bacterium is attenuated Salmonella typhimurium VNP20009 with cloned L-methioninase gene. The method for constructing this genetically engineered bacterium and the application thereof are also disclosed herein. In the current invention, our biologic drug for the treatment of breast cancer is a type of safe, non-toxic new drug with anti-tumor activity. It can highly express methioninase through recombinant DNA technology using attenuated Salmonella typhimurium VNP20009 as a carrier, which has a strong anti-tumor activity and can meet the needs. The preparation method is simple and easy to operate, showing good application prospect.
