Oral delivery of a therapeutic gene encoding glucagon-like peptide 1 to treat high fat diet-induced diabetes.

| Abstract |
The number of people suffering from insulin-independent type 2 diabetes mellitus (T2DM) is ever increasing on a yearly basis. Current anti-diabetic medications often result in adverse weight gain and hypoglycemic episodes. Hypoglycemia can be avoided with glucagon-like peptide (GLP)-1 receptor agonists, which are expensive and require daily injections that may result immune activation. This study demonstrates the use of non-viral vector based oral delivery of GLP-1 gene through enterohepatic recycling pathways of bile acids. Oral administration of the plasmid DNA (pDNA) encoding GLP-1 decreased diabetic glucose levels to the normoglycemic range with significant weight reduction in a high-fat diet (HFD) induced diabetic mouse model and a genetically engineered T2DM rat model. This novel oral GLP1 delivery system is an attractive alternative to treat late-stage T2DM conditions that require repeated insulin injection and can potentially minimize the occurrence of hypoglycemic anomalies.
