Adenoviral gene therapy for pancreatic cancer: where do we stand?

Designing E1 Deleted Adenoviral Vector by Homologous Recombination

Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...

Wild Type p53 Gene Transfer Increases Chemosensitivity and Apoptotic Response of PANC-1 Pancreatic Tumor Cell Line

The effect of p53 gene therapy on chemosensitivity and apoptotic response of PANC-1 tumor cells, which express high amount of mutant p53, to cancer chemotherapeutic agents of Etoposide and Doxorubicin was investigated. Comparison of the chemosensitivity of PANC-1 cells to its wild type p53 transfectants showed that wt-p53 expressing transfectants are more sensitive to both Etoposide and Doxorub...

Effect of NK4 Transduction in Bone Marrow-Derived Mesenchymal Stem Cells on Biological Characteristics of Pancreatic Cancer Cells

Pancreatic cancer usually has a poor prognosis, and no gene therapy has yet been developed that is effective to treat it. Since a unique characteristic of bone marrow-derived mesenchymal stem cells (MSCs) is that they migrate to tumor tissues, we wanted to determine whether MSCs could serve as a vehicle of gene therapy for targeting pancreatic cancer. First, we successfully extracted MSCs from ...

Antitumor effect of in vivo somatostatin receptor subtype 2 gene transfer in primary and metastatic pancreatic cancer models.

Our previous studies conducted in pancreatic cancer models established in nude mice and hamsters revealed that cloned somatostatin receptor subtype 2 (sst2) gene expression induced both antioncogenic and local antitumor bystander effects in vivo. In the present study, in vivo gene transfer of sst2 was investigated in two transplantable models of primary and metastatic pancreatic carcinoma devel...
