High blood glucose is responsible for several complications in type 1 and type 2 diabetes. Researchers at Karolinska Institutet in Sweden have identified a new antidiabetic substance that preserves the activity of insulin-producing beta cells and prevents high blood glucose in mice. The study is published in the journal Science Translational Medicine.
Although several families of glucose-lowering agents are currently used in diabetes therapy, none of them can stop or reverse the progression of the disease. Maintenance of adequate beta cell activity is essential to prevent the progression of type 1 and type 2 diabetes.
"In diabetes, beta cells are challenged to produce high amounts of insulin," says the study's first author Erwin Ilegems, senior researcher at the Department of Molecular Medicine and Surgery, Karolinska Institutet. "Our study shows that this leads to a hypoxic state that increases the levels of HIF-1alpha protein, which in turn reduces beta cell activity. By treating diabetic mice with the HIF-1alpha inhibitor PX-478 we successfully decreased their blood glucose levels."
