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.

Abstract: A polypeptide that contains an amino acid sequence present in human leptin blocks the inhibitory effect of human C-Reactive Protein on human leptin. Accordingly, such a polypeptide is implicated in an approach to treating or preventing conditions associated with the impact of CRP on leptin.

Abstract: Leptin controls the production of C-Reactive Protein (CRP), which, in turn, interacts with leptin to diminish its ability to signal satiety and reduce food intake. The interactions between leptin and CRP can be exploited to screen for agents capable of disrupting the leptin-CRP interaction, and thereby improve leptin signaling. Such agents can be used to reduce body weight, adiposity, and alleviate insulin resistance and diabetes.
