Enhanced therapeutic effect of cisplatin on the prostate cancer in tumor-bearing mice by transfecting the attenuated Salmonella carrying a plasmid co-expressing p53 gene and mdm2 siRNA.

Abstract:

:Prostate cancer urgently needs an efficient therapy. Here we demonstrated that cisplatin combined with gene therapy by transfecting the attenuated Salmonella that carry a plasmid containing p53 gene and MDM2 siRNA provided a super-synergistic effect on the inhibition of prostate cancer growth in vivo. This synergistic therapy was associated with the induction of apoptotic cell death with a decreased Bcl2 to Bax expression ratio and increased expression of cleaved caspase 3 and caspase 9 in the prostate cancer xenograft. These results indicate that cisplatin-chemotherapy in combination with targeting the MDM2/p53 axis is an attractive strategy to treat prostate cancer.

  • Effects of COX-2 inhibitor on growth of human gastric cancer cells and its relation to hepatocyte growth factor.

    abstract::It is known that hepatocyte growth factor binding to its receptor regulates gastric cancer progression and metastasis. HGF was found to up-regulate the expression of cyclooxygenase-2 gene and increases prostaglandin (PG) synthesis in gastric mucosa cells. Overexpression of COX-2 and increased PG secretion have also be...
