The Walsh laboratory investigates the signaling- and transcriptional-regulatory mechanisms that control both normal and pathological tissue growth in the cardiovascular system. Many of these studies involve analyses of the PI3-kinase/Akt/GSK/Forkhead signaling axis. This pathway is of critical importance in the regulation of organ growth and body size. Signaling through this pathway controls cellular enlargement (hypertrophy), cell death (apoptosis), and blood vessel recruitment and growth (angiogenesis). Related studies examine how alterations in the expression of adipocyte-derived cytokines, referred to as adipokines, interfere with normal signaling within the cardiovascular system and thereby contribute to cardiovascular disease. Finally, they examine how age-associated loss of skeletal muscle mass affects metabolic and cardiovascular function, and are exploring the possibility that muscle-secreted factors (myokines) confer some of the benefits of exercise training on cardiovascular and metabolic diseases.

Tamar Aprahamian, Ph.D, Assistant Professor
An Assistant Professor of Medicine, Dr. Aprahamian obtained a B.S. in Biology at Boston College, and a Ph.D. from the program of Cell, Molecular and Developmental Biology at Tufts University Sackler School of Biomedical Sciences. Her research studies have included developing a novel mouse model to study the interactions between atherosclerosis and autoimmunity.This revealed a synergy between the two disease processes promoted by impaired apoptotic clearance. Continued studies demonstrated beneficial effects of simvastatin on a mouse model of accelerated atherosclerosis and lupus. Dr. Aprahamian received a K-01 to study the role of PPARgamma agonists and adiponectin in systemic lupus erythematosus. She was the first to show that the immunomodulatory effects of PPARgamma agonists can ameliorate lupus-like disease, and lupus-associated atherosclerosis in several mouse models and this effect is mediated by adiponectin. Recently, she has started exploring the role of adiponectin in the adipose tissue microenvironment, and its effects on systemic metabolism and obesity-related inflammation.

David A. Goukassian, MD, PhD
NASA Human Research Program (IRP) identified space irradiation (IR) as one of the space flight risk factors to the cardiovascular (CV) system. In addition, long-duration space missions such as work on ISS, future lunar, near Earth asteroid, and Mars missions, as well as emerging civilian space travel activities, necessitate ground-based studies on degenerative CV risk assessment of space IR. Our laboratory has been funded by NASA to examine the effects of a single low dose space IR (specifically, 50 cGy, 1 GeV of ionized proton and 15 cGy, 1 GeV/n of ionized iron, days and up to 10 months after initial IR exposure) on the function of the heart during normal aging as well as on ability of the heart to recovery after an ischemic CV event, i.e., acute myocardial infarct -AMI. Further, our research is aimed at understanding the harmful effects of terrestrial ionizing radiation, specifically, cancer radiotherapy of the organs in the close proximity of the heart. Why do we want to study this? There is a large number of published epidemiological reports on evidence of increased incidence of CV diseases in cancer patients treated with radiotherapy emitters, this would be high dose radiation in multiple fraction, non-occupational (nuclear accidents such as Chernobyl and Fukushima) and occupational exposure (nuclear plant workers, radon miners, nuclear submarine crew). Moreover, a very recent report revealed 2.5-fold elevated mortality risk after cardiac surgery in cancer survivor patients 5-18 years after radiotherapy. Our goals are: (1) to understand and determine the early signs of increased cardiovascular risks due to cancer radiotherapy; (2) discover and eventually development prognostic factors/bio-markers for predicting ionizing radiation(IR)-mediated CV decease risks; (3) determine molecular mechanisms underlying the harmful effects of IR on CV health.

A professor of biophysics and physiology, research professor of medicine, and Director of the NMR Facility, is the Director of the Cardiovascular Magnetic Resonance Spectroscopy and Imaging Center. Dr. Hamilton pioneered applications of NMR spectroscopy for the noninvasive analysis of lipid structures and compositions in atherosclerotic plaques (ex vivo). Current research integrates the NMR analysis with images of plaques, both in vivo and ex vivo. The long-term goals of projects on atherosclerosis are to provide robust interpretations of MR images of plaques, and to distinguish in human arteries vulnerable plaques from stable plaques in vivo before plaque rupture occurs. A second major area of research is the transport of fatty acids in plasma, in membranes, and inside cells. His group has studied the binding of fatty acids to albumin and to intracellular fatty acid binding proteins (FABP) and determined high-resolution tertiary structures of FABP by NMR spectroscopic methods. New fluorescence approaches were developed in his research program to determine how fast fatty acids move across membranes and how fast they enter cells. Dr. Hamilton is a founding organizer of the international workshop, Fatty Acid Uptake Into the Brain. Currently Dr. Hamilton is Associate Editor for Lipids and Obesity Research and a member of the Editorial Board of Journal of Lipid Research.
Victoria L. M. Herrera, M.D.
A pediatric cardiologist trained at Children’s Hospital Boston, Harvard Medical School, is Professor of Medicine, and Director for the Ultrasound Micro-Imaging Core. She was a former NIH Physician Scientist Awardee and received the Syntex Scholar’s Award for excellence in Cardiovascular Research for work done at the Whitaker Cardiovascular Institute. She was a member of the NIH Task Force for Hypertension, AHA Massachusetts Affiliate study section, NIH Cardiovascular-A Study Section, AHA North American Consortium Study Section, and Hypertension editorial board. Currently, she is on the editorial board for Physiological Genomics, and reviewer for NIH program project grants. Her research program focuses on an integrative molecular-genetic analysis of mechanisms underlying the acceleration of coronary artery disease and strokes by hypertension-hyperlipidemia interactions, fetal programming of adult-onset vascular diseases, endothelial injury/repair balance in aging and vascular diseases.

Dr. Jiang, an Associate Professor of Pharmacology and Medicine, is a member of The Whitaker Cardiovascular Institute and Department of Pharmacology & Experimental Therapeutics. He received Ph.D. in Biochemistry at University College, University of London in England and then postdoctoral training at Joslin Diabetes Center, Harvard Medical School and University of Massachusetts School of Medicine.
Research Interests: Metabolic Syndrome, Obesity, Diabetes and Innate Immunity. Currently, Jiang lab mainly focuses on understanding how insulin signaling networks and innate immunity regulate metabolic functions.
1. Exploring the role of neutrophils and neutrophil elastase (NE) in the development of obesity-related adipose inflammation, insulin resistance and cardiovascular dysfunction. Using quantitative serum proteomic approach, The Jiang lab identified that there is an imbalance between NE and its inhibitor alpha-1-antitrypsin in both obese human subjects and mouse models. Interestingly, both NE knockout mice and human A1AT transgenic mice are resistant to high-fat diet-induced body weight gain, adipose inflammation, fatty liver and insulin resistance. NE knockout mice have higher AMP kinase activity and fatty acid oxidation rate. Currently, Jiang lab is exploring molecular and cellular mechanisms whereby obesity regulates neutrophils activity and subsequent adipose inflammation, fatty liver, insulin resistance and cardiovascular dysfunctions with mouse models.
2. CDP138 and its signal networks related to glucose and lipid metabolisms. Using a SILAC-based quantitative proteomics approach, we identified multiple phosphoproteins from insulin-stimulated adipocytes. As a result, Jiang lab found that CDP138, a novel phosphoprotein containing C2 domain, is involved in the regulation of GLUT4 translocation. With CDP138 knockout mouse model, Jiang lab is using TIRF microscopy-based live cell imaging, protein-protein interactions, gene expression profiling to study the signal network of CDP138 and its role in the regulation of glucose and lipid metabolisms and neuronal functions.

Michael T. Kirber, Ph.D., Associate Professor
Is an Associate Professor of Medicine and Technical Director of the Cellular Imaging Core. His research involves the development and application of advanced imaging systems for use in fluorescence microscopy. Biological interests focused on the study of the relationships existing between ion channel activity, intracellular calcium, and the contractile state of smooth muscle. He has studied mechanisms linking the activity of cation-selective mechanically gated ion channels to voltage gated calcium-selective channels and the release of calcium from intracellular storage sites in smooth muscle, processes which may be essential to certain myogenic responses. His research also involves spontaneous local release of intracellular calcium, known as calcium sparks. He performed the first three dimensional imaging of calcium sparks, which suggested the existence of microdomains within the cell which are important in determining the relationship between calcium sparks and spontaneous outward currents which they can generate. Other recent efforts involved the relationship between protein kinase C activity and the release of calcium from intracellular stores, which may be a novel physiologically important negative feedback regulatory mechanism.
Dr. Kirber’s education is in electrical and biomedical engineering. He did his post-doctoral training in the Physiology Department at University of Massachusetts Medical School where he studied smooth muscle cells using patch clamp techniques.

A professor of medicine, is fellow of the AHA Councils of Arteriosclerosis and Basic Science, and former member of the AHA National Molecular Signaling I study committee. He serves as reviewer for NIH special review study sections and was a past AHA Established Investigator. His research program focuses on an integrated molecular-genetic analysis of essential hypertension and associated target organ complications (i.e.: renal disease, cardiac hypertrophy and vascular cognitive impairment) using classical genetics and related genomic approaches. His studies include genetic rat models of essential hypertension and spatial learning and memory. His research also includes genetic association studies in selective human populations. The molecular characterization of novel angiotensin II, vasopressin and endothelin receptors in his laboratory has provided additional bases for ongoing investigation of their respective physiologic and pathophysiological roles in cardiovascular and neurobiological functions such as in learning and memory. These focused studies are complemented with classical QTL (quantitative trait locus) analysis and congenic rat development that are currently being performed to identify QTGs (quantitative trait genes) influencing blood pressure, cardiac hypertrophy, renal disease and learning and memory. Together with Dr. Victoria L. M. Herrera, Dr. Ruiz-Opazo has pioneered the production of transgenic rat models at BUSM.

Dr. Seta is an Assistant Professor of Medicine in the Vascular Biology Section. Her major research interests are arterial stiffness, aortic remodeling and hypertension. Arterial stiffness is a vascular condition characterized by impaired endothelial function and aortic remodeling resulting in loss of elasticity of large blood vessels and it has recently emerged as an independent risk factor for cardiovascular events. Dr. Seta’s lab showed that arterial stiffness develops rapidly in a model of diet-induced obesity, which mimics the human metabolic syndrome. We focus on the discovery of novel therapeutic targets and life-style interventions that can prevent or reverse arterial stiffness and its deleterious complications, including hypertension, particularly in settings of obesity and insulin-resistance. The laboratory optimized innovative in vivo and in vitro approaches to measure arterial stiffness and active and passive properties of blood vessels. Among others, we use high-resolution ultrasound echocardiography, radiotelemetry and high-fidelity pressure catheters, to assess arterial stiffness, blood pressure and cardiac and arterial functions. In addition, Dr. Seta’s laboratory investigates the molecular mechanisms of aortic dissection and aneurysm, two deadly cardiovascular conditions affecting the aorta for which, currently, there are no pharmacological treatments.
