Sudden cardiac death (SCD) claims more lives each year than all other causes of death combined. The underlying mechanisms remain unclear, precluding the design of new, more effective therapies. Progress in understanding SCD mechanisms has been limited by the lack of a suitable animal model resembling the human phenotype. While reactive oxygen species (ROS) have been strongly implicated in the pathogenesis of both SCD and heart failure (HF), insight into the mechanistic role has been limited by the lack of sophisticated tools. Dr. Dey’s work reveals important new mechanistic and therapeutic insights with potential for broad clinical translation. Her studies have demonstrated that antioxidant flux depends on mitochondrial substrate catabolism with the availability of NADPH as a major rate controlling step. Further, she developed several unique and highly clinically-relevant animal models, including the first female model of non-ischemic HF with spontaneous SCD. Additional studies by Dr. Dey have revealed that mitochondrial ROS (mROS) is the principal driver for SCD. Importantly, she also demonstrated that scavenging mROS in vivo mitigates SCD and reverses HF. Her ongoing research is aimed at dissecting the mechanisms by which chronic elevations in sympathetic activity induce mROS-mediated adverse remodeling in the heart, leading to HF and increased risk of SCD. Her research program focuses on the design of potential new in vivo therapies for HF and SCD by reducing sympathetic stress-mediated adverse remodeling in the heart (e.g., using gene therapy to convert sympathetic nerves to parasympathetic nerves, device-based stimulation of sympathetic nerves). Dr. Dey’s goal is to form strong, long-term collaborations to employ a multidisciplinary translational approach to address questions of clinical significance related to HF and SCD.

In addition to glucose, breast tumors often utilize glutamine to support biomass and energetic requirements for cell proliferation and migration. While glutamine not only drives breast cancer cell growth, it is also a necessary amino acid for normal cell function for a wide range of other cells within the human body, including immune cells that target and kill cancer cells. Dr. Edwards' primary research focus is to investigate the microenvironmental role of glutamine metabolism in regulating tumor immunity and metastatic progression in breast cancer.

Dr. Kroncke is a promising young scientist whose research focus has been to explain the interplay between membrane protein flexibility and structure that leads to robust function and dysfunction involved in human disease, with a special emphasis on ion channels involved in the heart contraction cycle. The increasing use of next generation sequencing in the clinical arena is uncovering a large number of variants across all genes, but methods to predict their pathogenicity are not well established. This results in an increasing number of “variants of uncertain significance” (VUSs), a major emerging problem in genomic medicine. Rare variants (mutations) in the cardiac ion channels are implicated in diverse heart diseases, including long QT syndrome (LQTS), short QT syndrome (SQTS), and Brugada syndrome (BrS), but are also common in healthy populations. While multiple algorithms predict whether ion channel variants are deleterious (SIFT, PolyPhen-2, PredSNP, CADD, etc.), too many neutral variants are classified as disease-causing. The long-term research interest of Dr. Kroncke is to improve our understanding of the clinical burden of ion channel non-synonymous single nucleotide polymorphisms (nsSNPs) on carriers. He believes predicting protein-specific functional phenotypes accurately of nsSNPs within these genes is the best path to reaching this goal, initially focused on ion channels associated with Long QT Syndrome.

Reactive oxygen species (ROS) are often damaging compounds that can contribute to tissue injury and inflammation in the context of inflammatory bowel disease and colorectal cancers. However, ROS is also crucial for maintaining normal tissue homeostasis, and recent data have indicated that the exact role of ROS and antioxidants in intestinal homeostasis and disease is quite complex and likely highly contextual. Dr. Short’s research focuses on a family of antioxidant proteins known as the glutathione peroxidases and how they modify intestinal stem cell function, immune responses, and epithelial restitution using a variety of mouse models, as well as novel 3D patient-derived organoids. Ultimately, this work will yield a greater understanding of how individual antioxidant proteins modify redox homeostasis and contribute to intestinal health.

As a cancer epidemiologist, Dr. Shu's research interests focus on the urgent need to develop novel and reliable biomarkers for cancer risk and prognosis. Dr. Shu has been actively conducting research in identifying novel biomarkers for a variety of cancers using genomics, transcriptomics, methylomics, proteomics, and metaboldata. For the first time, his research provided strong evidence for a potential causal relationship between fasting insulin and breast cancer risk using the Mendelian randomization approach. Dr. Shu received the AACR Scholar-in-Training Award for his work in 2017. The study has recently been published in The International Journal of Epidemiology and has received many accolades. Dr. Shu later conducted two prospective metabolomics studies of colorectal and pancreatic cancers, which were the first studies conducted in Asian populations using pre-diagnostic samples. Both works have recently been published in The International Journal of Cancer. Dr. Shu further developed a promising K99/R00 application based on his expertise in cancer etiology, causal inference, and omics studies.
