- The National Heart, Lung, and Blood Institute awarded the University of Arizona $108,950 on September 1, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to develop nanoplatforms for co-delivery of drugs and genes to protect lung endothelium from neonatal and pediatric lung injury. The recipient will optimize nanoparticle formulations for stability, safety, and endothelial targeting in neonatal lungs, characterizing physicochemical properties that influence targeting...
- The National Institutes of Health National Heart Lung and Blood Institute awarded the University of Arizona $558,127 on August 1, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to investigate cardiac SK channel remodeling in heart disease and arrhythmias. The research combines experimental and computational studies to address gaps in understanding small-conductance Ca²⁺-activated K⁺ channels (SK channels) in diseased hearts. The work focuses on two primary challenges: the...
- Grant Award Summary The University of Arizona received a $576,786 Project Grant from the National Heart, Lung, and Blood Institute (NHLBI) under the Cardiovascular Diseases Research program (CFDA 93.837), awarded September 5, 2025, with completion targeted for August 31, 2028. This research initiative investigates protein translation mechanisms underlying oxidative stress response in heart failure, specifically examining the role of YTHD2 (a YTH domain-containing N6-methyladenosine binding...
- The National Institutes of Health National Heart, Lung, and Blood Institute awarded the University of Arizona $743,545 on July 15, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to develop deep learning methods for drug discovery targeting atrial fibrillation. The research focuses on identifying selective inhibitors of small conductance calcium-activated potassium (SK) channels as a therapeutic approach to atrial fibrillation. The project builds on the investigative...
- The National Heart, Lung, and Blood Institute awarded the University of Arizona $577,065 on September 1, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to investigate the roles of endoplasmic reticulum stress in calcium-dependent cardiac arrhythmias. The research addresses how endoplasmic reticulum stress response contributes to acquired cardiovascular diseases with high arrhythmic risk, particularly those involving hyperactivity of the ryanodine receptor (RYR2), the...
- The National Institute of Arthritis and Musculoskeletal and Skin Diseases awarded the University of Arizona $375,381 on September 2, 2026, under the Arthritis, Musculoskeletal and Skin Diseases Research program (CFDA 93.846) to develop a small-molecule drug discovery platform targeting MYBPC1 mutations that cause distal arthrogryposis. The project addresses the absence of available therapeutics for distal arthrogryposis, a congenital muscle disorder affecting approximately 1 in 3,000 live births...
The National Heart, Lung, and Blood Institute awarded the University of Arizona $726,242 on August 20, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to characterize the cellular and molecular role of GATA4 in bicuspid aortic valve disease. The project, R01HL183091, runs through May 31, 2030, with place of performance in Tucson, Arizona. The award funds three research aims. Aim 1 comprehensively characterizes a GATA4S379G mouse model of bicuspid aortic valve disease, quantifying birth rates, mortality, sex-specific penetrance, and assessing cardiac structure and function through echocardiography and magnetic resonance imaging. Aim 2 applies single-cell RNA sequencing, spatial transcriptomics, and HiChIP to define cell type-specific regulatory networks disrupted by mutant GATA4 during valve morphogenesis, focusing on altered AP-1/NFAT/TNFA signaling that drives abnormal cusp formation. Aim 3 uses patient-derived and isogenic human induced pluripotent stem cells carrying the GATA4S377G mutation to define how this variant disrupts transcriptional regulation, chromatin architecture, and cellular function across endocardial cells, fibroblasts, and cardiomyocytes, employing multi-omic integration and functional assays of endothelial-to-mesenchymal transition and extracellular matrix remodeling. The University of Arizona operates as the Arizona Board of Regents for administrative and financial purposes. This is a project grant, the standard NIH research grant mechanism.
