Using the model of cyclophosphamide-accelerated diabetes in non-obese diabetic (CAD-NOD) mice, we report that recombinant adenovirus mediated PDX-1 gene therapy, ameliorates hyperglycemia in CAD-NOD mice. Our data demonstrate that 43% of the overtly diabetic CAD-NOD mice treated with Ad-CMV-PDX-1 became normoglycemic and maintained a stable body weight.
A novel approach to this problem is currently being pursued by a small biotech company named Orgenesis, which initiated its approach by asking the following question: What if a diabetes patient's own cells-extracted from his or her own mature tissue-could be made to produce insulin, secreting the compound automatically when needed? This particular variety of cell therapy is a form of what has been dubbed "autologous cell replacement."
Orgenesis has successfully tested its technology in mice, rats and pigs, and is working toward initiating clinical trials in humans.
