10 February DRC Director's Report - February 2021 February 10, 2021 By The Fraternal Order of Eagles Diabetes Research Center DRC, Diabetes, FOE Diabetes Research Center 0 The exact mechanisms underlying the metabolic effects of gastric bypass or bariatric surgery remain unclear. At the University of Iowa Carver College of Medicine, Mohamad Mokadem, MD, Assistant Professor of Internal Medicine and member of FOEDRC, and his research team have developed an animal model of bariatric surgery, which they are using to understand the underlying mechanisms by which this treatment not only prevents obesity but also reverses diabetes. Mokadem’s lab studied obese animals that underwent bariatric surgery (i.e. weight loss surgery) in order to understand the body’s physiologic response to such a treatment. Understanding these responses could lead to the development of similar therapies that are less invasive. They found that one type of bariatric surgery, namely the Roux-en-Y Gastric bypass, induces its weight loss and other metabolic benefits by altering the activity of a specific nerve (the splanchnic) that connects the gut to the brain to cause direct burning of the fat within the abdomen. This fat burning increases energy expenditure and is specific for this model of bariatric surgery. The new findings in their study identified a receptor within the intestine (the Endocannabinoid-receptor-1) that seems to be responsible for activating this “splanchnic” nerve signal to cause the metabolic benefits of this surgical procedure. The main implication of these findings on patient care is the future possibility of manipulating a specific receptor or its downstream effectors or the splanchnic nerve itself, to mimic the long-lasting effects of bariatric surgery. The more we understand details of how bariatric surgery works the more we will understand the underlying changes that are leading to the obesity epidemic. In addition, this research may lead to less invasive options to manage obesity and to reverse diabetes. Related Articles DRC Director's Report - January 2021 A recent study by a team of UI researchers led by E. Dale Abel, MD, PhD, Director, FOEDRC discovered eating a ketogenic diet rescued mice from heart failure. The study, published in the November issue of the journal Nature Metabolism, was one of three companion papers from independent research teams that all point to the damaging effects of excess sugar (glucose) and its breakdown products on the heart. The UI study also revealed the potential to mitigate that damage by supplying the heart with alternate fuel sources in the form of high-fat diets. Given its need for a constant, reliable supply of energy, the heart is very flexible about the type of molecules it can burn for fuel. Most of the heart’s energy comes from metabolizing fatty acids, but heart cells can also burn glucose and lactate, and also ketones. DRC Director's Report - February 2019 The Department of Defense office of the Congressionally Directed Medical Research Programs has awarded DRC member, Ethan Anderson, Associate Professor College of Pharmacy, funding as part of its Peer Reviewed Medical Research Program (PRMRP) Discovery Award competition. The project is: Exploiting the Paracrine-Like Effect of Prohibitin-1 to Treat Septic Cardiomyopathy. The grant will provide $310,000 in total support over a 2-year period. DRC Director's Report - December 2018 As we come to the end of another successful year for the FOEDRC, I want to thank the FOE and my colleagues within the Diabetes Research Center for continuing to push the research boundaries to improve the lives of many who suffer from diabetes. On a personal note, I received a number of honors for my work this year including being asked to deliver the Presidential Lecture of the University of Iowa, receiving Fraternal Order of Eagles Humanitarian Award and the 2018 History Makers Award - the African American Museum of Iowa (AAMI). My receipt of this recognition is really a recognition of what you do and I consider myself very fortunate to lead such an outstanding organization. To close out the year I thought you might be interested in reading about some ways that our researchers are turning “fun and games” into a benefit for our patients with diabetes.

DRC Director's Report - November 2018 We have known for a very long time that obesity is associated with many cardiovascular and metabolic diseases. Type 2 diabetes, fatty liver disease (where liver stores fat in large lipid droplets), coronary artery disease, heart failure, and many more chronic diseases are all linked to obesity. DRC Director's Report - March 2019 Brian T. O’Neill, MD, PhD, assistant professor in the Division of Endocrinology in the Department of Internal Medicine and member of the FOEDRC recently published in the journal Diabetes the discovery that FoxO proteins, which are transcription factors that regulate DNA, are the critical regulators of diabetes-related muscle atrophy.
