Volker Adams obtained his PhD at the University of Konstanz in Biology and his work focused on isolation and characterization of mitochondrial contact sites in different organs. His postdoctoral training was in molecular genetics at the Institute of Molecular Genetics, Baylor College of Medicine, Houston Texas, USA. After moving to Leipzig, and taking over the position as head of the research laboratory at the Heart Center Leipzig his main research interest during the last 20 years is to understand the molecular changes in the endothelium and the skeletal muscle related to the beneficial effects of exercise training.
Steven L. Britton is a Professor of both Anesthesiology and Molecular & Integrative Physiology at the University of Michigan. Based upon the strong linkage between low exercise capacity and all-cause morbidity he hypothesized that: variation in capacity for aerobic metabolism is the central mechanistic determinant between disease and health (aerobic hypothesis). As an unbiased test of this hypothesis, Britton and Lauren G. Koch demonstrate that two-way artificial selection of rats for low and high exercise capacity also produces rats that differ for numerous disease risks, including the metabolic syndrome, fatty liver disease, Alzheimer’s degeneration, and obesity. This rat model system is shared with investigators at over 50 institutions to understand exercise as it relates to health and disease.
Since 2003, the laboratory of Dr. Yan Burelle has developed a research program focused mitochondrial physiology. The central interest of his laboratory has been to integrate multiple facets of mitochondrial biology to gain a global understanding of the importance of these organelles in physiological homeostasis, and development of human diseases, including acquired cardiac and skeletal muscle pathologies as well as genetic mitochondrial diseases. His laboratory has developed an expertise in the assessment of multiple mitochondrial functions and quality control mechanisms, which have been used not only in basic studies using animal models, but also in tissues from patients in the context of translational research. Some of the recent work from his laboratory focuses on mechanisms involved in mitochondrial quality control in the heart, and their implication in the maintenance of mitochondrial health and cardiac response to stress. Over the years, his laboratory benefited from uninterrupted funding from CIHR, and NSERC. Dr. Burelle received salary support from FRSQ for several years and was awarded the Pfizer Cardiovascular Award, and the Merck-Frost New Investigator Award for his work. He is the author of several articles published in leading journal of his field including Autophagy, Circulation Research, and the American Journal of Respiratory and Critical Care Medicine.

Dr. Coleman’s research focuses on triacylglycerol biochemistry and metabolism, particularly the glycerol-3-phosphate and monoacylglycerol pathways of triacylglycerol synthesis and the enzymes that activate the long-chain fatty acids substrates of the acyltransferases involved in these pathways. Her laboratory cloned and characterized 2 novel glycerol-3-phosphate acyltransferases, GPAT2, a major GPAT in testes and GPAT 4, a major GPAT whose deficiency in mice results defective energy metabolism. Her studies of mice that are deficient in GPAT1 showed the importance of this isoform in the development of hepatic steatosis, as well as its role in diet and hormonally induced insulin resistance.
Her studies on acyl-CoA synthetases, enzymes that activate the long-chain fatty acids substrates for both glycerolipid biosynthesis and fatty acid oxidation have demonstrated that acyl-CoAs are compartmentalized within cells. Characterization of mice with tissue-specific deficiencies of acyl-CoA synthetase-1 (ACSL1) shows a requirement for this isoform in targeting fatty acids towards beta-oxidation in heart, white adipocytes, brown adipocytes, and muscle. Without ACSL1, energy metabolism in these tissues is impaired, and glucose homeostasis is compromised. Her studies are currently incorporating approaches such as metabolomics in identifying novel pathways that connect acyl-CoA metabolism with metabolically dysregulated disease states, including cardiac hypertrophy, insulin resistance, and cancer.
Our research determines the roles of intermediary metabolism in governing integrated physiological homeostasis. In the past five years, my laboratory created a platform for metabolic analysis that includes the development of novel germline and tissue-specific mouse strains that are unable to appropriately metabolize ketone bodies, which are key integrators of mitochondrial oxidative substrate metabolism. My laboratory’s metabolic analyses of these strains include stable isotope-manipulated systems coupled with NMR and LC/MS computational metabolomics methods to quantitatively map substrate fate and measure metabolic flux. Together, the tools and approaches developed and used in the lab offer a unique window into the metabolic adaptations and maladaptations in myocardial disease, nonalcoholic fatty liver disease, and obesity/metabolic syndrome.

Åsa Gustafsson is interested in understanding the molecular pathways that regulate the life and death of cardiac myocytes. Activation of cell death pathways is a common occurrence in cardiovascular disease and contributes to the development of heart failure. Using genetic and molecular biology approaches, Dr. Gustafsson is elucidating the pathways involved in regulating mitochondrial structure, function, and degradation in myocardial cells. Specifically, she is interested in how the E3 ubiquitin ligase Parkin regulates mitochondrial turnover in cardiac myocytes. Defects in this pathway leads to accumulation of aberrant mitochondria and loss of myocytes. Dr. Gustafsson joined the Skaggs School of Pharmacy and Pharmaceutical Sciences in October 2009. Prior to coming to UCSD, she was an Assistant Professor at San Diego State University. She received her Ph.D. in Biomedical Sciences from the Department of Pharmacology at the University of California, San Diego, CA in 2001.

I use non-invasive magnetic resonance spectroscopy (MRS) to investigate the etiology of insulin resistance in type 2 diabetes and specifically the causes and consequences of fat storage in heart, liver and muscle. To this end, I use cardiac and hepatic 1H-MRS to study ectopic fat storage in these tissues and 31P-MRS to address energy metabolism in vivo. Applying these tools, I found that in vivo mitochondrial function is reduced in diabetic patients. Furthermore, I showed that lipid content and oxidative capacity in cardiac and skeletal muscle are modulated by endurance training and acute exercise and that high concentrations of FFA- as seen in diabetes - lead to increased fat storage. In 2010, I received a NWO-VENI award to investigate the role of hepatic mitochondrial energy and lipid metabolism in type 2 diabetes. Based on pilotwork generated in my team, I received in 2012 an EFSD research grant to investigate the muscle metabolite acetylcarnitine; this work has resulted in a recent publication where we showed that acetylcarnitine is detectable with 1H-MRS and that levels are inversely related to insulin resistance (Lindeboom, JCI 2014). With a recent NWO-VIDI award I will investigate the interaction of NAD+ and acetylcarnitine and their role in protein acetylation and the development of insulin resistance.

Stefan Wagner is Professor for Translational Cardiology at the University of Regensburg. He finished his medical training and received his M.D. at the Georg-August-University of Goettingen. In his thesis he investigated the role of Na/Ca exchange for cardiac Na and Ca metabolism upon reactive oxygen-species-dependent (ROS) injury. During his post-doctoral training he studied the role of Ca-Calmodulin-dependent serine/threonine kinase II (CaMKII). He identified a novel CaMKII-dependent Na entry pathway by voltage-gated Na channels (NaV1.5) and showed its relevance for cardiac Ca overload, contractile dysfunction and arrhythmias. Since his appointment at the University of Regensburg he strongly collaborates with cardiac surgeons and pharmaceutical companies to translate this findings into the clinic. He currently studies two potential CaMKII inhibitors in various animal models and human tissue. Recently, he also identified a novel link from sleep-disordered breathing to cardiac arrhythmias in patients by showing a ROS-dependent activation of CaMKII that leads to profound dysregulation of cardiac Na and Ca metabolism.
