The grant funds development of an electromagnetic-actuated dynamic cell culture system designated "MagniWell-12," designed to advance research on airway epithelial cells by simulating physiological stretch-relax...
- Federal Project Grant Award Summary Iowa State University of Science and Technology received a $1.18 million Project Grant from the National Heart, Lung, and Blood Institute (NHLBI) under the Cardiovascular Diseases Research program (CFDA 93.837), effective September 1, 2025, through August 31, 2029. The award funds development of a Scientific Machine Learning (SciML)-accelerated cardiovascular digital twin platform designed to personalize long-term heart valve interventions for valvular heart...
- The National Heart, Lung, and Blood Institute awarded the University of Missouri System $840,770 on July 1, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to investigate the interplay of central and peripheral vascular effects of insulin in obesity. The research focuses on skeletal muscle blood flow impairment and glucose uptake dysregulation in individuals with obesity and insulin resistance. The project examines how central (brain) insulin sensitivity drives sympathetic...
The National Heart, Lung, and Blood Institute awarded The University of Iowa $743,341 on September 1, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to elucidate the role of insulin receptor substrate 2 (IRS2) in cardiac calcium homeostasis and arrhythmogenesis. The research addresses sudden cardiac death from ventricular arrhythmias following myocardial infarction, driven by chronic sympathetic overactivation that disrupts cardiomyocyte calcium homeostasis and triggers dangerous heart rhythms. Current beta-blocker therapy suppresses both pathological and essential physiological signaling, leaving substantial patient populations inadequately protected. The project combines molecular, cellular, and physiological techniques to test the hypothesis that IRS2 orchestrates a cardioprotective mechanism preserving calcium homeostasis during sympathetic stress and protecting against ventricular arrhythmias and adverse remodeling in ischemic hearts. Preliminary work has identified IRS2 induction in post-MI hearts of both humans and mice, demonstrated that genetic IRS2 overexpression suppresses catecholamine-induced arrhythmias, and identified a specific phosphorylation site on IRS2 that acts as a sympathetic stress-activated phospho-switch driving beta-adrenergic receptor internalization. A phospho-deficient IRS2 knock-in mouse model recapitulates the arrhythmic phenotype of cardiac IRS2 deficiency. Place of performance is Iowa City, Iowa. The period of performance runs from September 1, 2026, through May 31, 2030. This is a Project Grant assistance type award.
