Drug store researcher John Ussher led new research study identifying a protein that could be crucial to establishing treatments to prevent a type of cardiac arrest that prevails however frequently hidden in people with Type 2 diabetes

“We understand individuals with diabetes take drugs for many years to manage their blood sugars, however the drugs do not cure their diabetes,” stated lead author John Ussher, associate professor in the Professors of Drug Store and Pharmaceutical Sciences. “The bulk ultimately die not from high blood glucose, but from cardiovascular disease.”
People with Type 2 diabetes have a defect in their hearts’ ability to burn carbohydrates as a fuel source, Ussher explained, which can eventually result in diastolic heart failure, in which the heart contracts normally but does not relax correctly in between pumps.
Ussher’s lab used a mix of genetic modifications and drug treatments in animal models to show this process can be stopped by obstructing the action of a crucial protein called FoxO1.
“Our research demonstrated that if you can repair the heart’s ability to burn sugar for fuel, then the heart can relax better and not get this type of heart failure in the presence of diabetes,” said Ussher, who is Canada Research Study Chair (Tier 2) in Pharmacotherapy of Basal Metabolism in Obesity and a member of both the Alberta Diabetes Institute and the U of A’s Cardiovascular Research Centre.
Narrowing in on the target
Ussher kept in mind that Type 2 diabetes affects almost 400 million people worldwide. While numerous will experience systolic heart failure or problems with the way their heart pumps, research studies reveal just as many will have diastolic or relaxation issues, however they typically have no symptoms. Ussher prompted earlier screening for diastolic heart problem among individuals identified with diabetes and pre-diabetes.
“This is devastating for the people and a significant problem on the health-care system,” Ussher said. “There are no approved treatments that can reverse this type of cardiac arrest, which is why it’s very crucial to attempt to develop treatments.”
Ussher’s next action will be to try to better understand the system of the experimental drug they utilized to inhibit the FoxO1 protein, and after that improve upon it, as it has not been evaluated in humans and might have unknown side-effects.
“Another issue is FoxO1 is a protein that manages the expression of hundreds or thousands of genes,” he described. “There’s one gene that we want to modify to benefit the cardiac arrest, however what are the other 99 or 999 genes being affected by customizing this protein? How might these genes affect the body?”
A better technique, Ussher said, would be to modify the specific protein that hinders sugar metabolic process, whose gene expression is controlled by FoxO1.
“We believe that would be a more particular and better target that would have less possible for unfavorable impacts, so the long-term objective for us is to concentrate on using chemistry and other techniques to make new substances that could target that particular protein,” he stated.
