UAB scientists have proved through years of research that high blood sugar causes the body to overproduce a protein called TXNIP, which is increased within the beta cells in response to diabetes, but had never previously been known to be important in beta cell biology. Too much TXNIP in the pancreatic beta cells leads to their deaths and thwarts the body’s efforts to produce insulin, thereby contributing to the progression of diabetes. But UAB scientists have also uncovered that the drug verapamil, which is widely used to treat high blood pressure, irregular heartbeat and migraine headaches, can lower TXNIP levels in these beta cells — to the point that, when mouse models with established diabetes and blood sugars above 300 milligrams per deciliter were treated with verapamil, the disease was eradicated.
