Human and animal diabetes mellitus were controlled by a dietary treatment supplemented with either a sulfonylurea drug or insulin injection. Insulin injections were inconvenient and the hypoglycemia induced by insulin-overdose could be fatal. Sulfonylurea drugs were administered orally, however, do not typically provide satisfactory control of blood glucose as a starting treatment in 25% - 30% patients. Therefore, it was imperative to develop a method for the control of human and animal diabetes mellitus. Recently, insulin gene transferred and expressed in non-pancreatic cells as a means for the treatment of diabetes was developed rapidly in the expanding gene therapy. Retrovirus, lentivirus, adenovirus, adenoassociated virus and herpes simplex had been used as viral vectors, and the constructed viral-insulin gene was successfully transferred into diabetic rat cells. A gene, containing promoter, enhancer and rat type I insulin gene (a-chain, b-chain and signal peptide), was constructed into a retrovirus vector in the study. The constructed viral-insulin gene was transferred into mouse fibroblast cell. The insulin concentration in 3-day cultured mouse fibroblast cells was 4806.35 ± 53.72 pg/ml. The insulin concentration for the viral vector containing enhancer and promoter of rat insulin gene was higher than the vector containing only insulin gene by a 61% increase in the cultured mouse fibroblast cells. The enhancer and promoter activity of rat insulin gene would be an important determinant for the expression of insulin gene. The secreted amount of insulin by retrovirus vector contained enhancer/promoter gene in this study could achieve as high concentrations (4806.35 ± 53.72 pg/ml) as the insulin injection therapy. Blood glouse decreased sig- nificantly for at last 10 days demonstrated that transfection, direction injection of viral-insulin gene into pancreas of diabetic rat, was successful. These studies suggest that the retrovirus vector might be used to transfer the insulin gene in vitro and in vivo.   </p
