Glucagon-Like Peptide-1 agonists, reperfusion injury and type 2 diabetes
Primary supervisor: Anastasia Mihailidou
Diabetes is the fastest growing disease worldwide and in the past two decades the prevalence has doubled in Australia, contributing to significant disability, with increased mortality and morbidity from acute myocardial infarction (AMI). Patients with diabetes have a two-fold increase in the risk of short- and long-term mortality after AMI. Current anti-hyperglycemic medications reduce morbidity and mortality in patients with diabetes, however diabetic patients continue to have 2- to 4-fold greater risk of myocardial infarction and heart failure. Additional treatment strategies are needed that prevent these cardiovascular complications in diabetes. The glucagon-like peptide 1 (GLP-1) agonists are an exciting new class of anti-hyperglycaemic medication that not only lower glucose levels, but also reduce weight and have protective effects on pancreatic islets. This project will evaluate the cardiac effects of Liraglutide, a GLP-1 agonist, to protect against AMI using Zucker fatty rats at 12 weeks as a model of type 2 diabetes. Our recent studies show that during myocardial ischemia-reperfusion, cardiac damage is aggravated in Zucker male rats at 12 weeks of age, an established animal model of type 2 diabetes. The studies will involve both functional studies and molecular techniques (immunohistochemistry, western blot analysis).
