    Understanding Complex Interactions in Metabolic and Cardiovascular Disease:
    Genetics, the Microbiome, Sex, and Diet

    Jake Lusis, PhD

    Professor of Microbiology, Human Genetics and Medicine, University of California, Los Angeles


    One important application of animal models is, of course, to identify mechanisms through experimental perturbation. A less well-known application is to utilize natural variation to study complex interactions. The lab detailed in this presentation studies a panel of diverse inbred strains of mice to understand interactions between genetics, sex, the microbiome, and diet in the context of cardiometabolic disease.


    One surprising research finding is that genetic variation of the host is a major determinant of the composition of the gut microbiome. For example, when a panel of common inbred strains of mice was maintained in the same vivarium and fed the same diet, the heritability of gut microbiota was about 40% or higher for most genera of gut bacteria. Nevertheless, the microbiome could be dramatically altered by dietary challenge, and microbiota transplantation studies showed that the effects of the diets on the host were dependent in part upon genetic background, sex, and microbiome composition. While the lessons gleaned from studies in mice may not be directly translatable to humans, an understanding of the basic principles will help guide human studies.

    Bench to Bedside in Oncology: Translation of Cancer Vaccines from Mouse Models
    to Human Clinical Trials

    Jay Berzofsky, MD, PhD

    Chief, Vaccine Branch; Senior Investigator Head, Molecular Immunogenetics and Vaccine Research Section, National Cancer Center, NIH


    This presentation will review two cancer vaccine platforms developed in transgenic mouse models that were successfully translated to human trials with promising results. The first was developed by studying TARP, a prostate cancer antigen discovered at NCI, mapping HLA-A2-presented epitopes, and testing these in HLA-A2 transgenic mice. Additional studies in mouse models were conducted following amino acid modification to improve binding to HLA-A2 – a process referred to as ““epitope enhancement.” The mouse studies led to a phase I clinical trial in patients with stage D0 prostate cancer, in which the primary tumor is removed but a rising PSA indicates microscopic recurrence, before any tumor can be seen radiographically.


    The second platform is a recently developed vaccine targeting the HER2 oncogene, responsible for about one-quarter of breast cancers and a smaller percent of several other cancers. For mice, an adenovirus expressing the extracellular and transmembrane domains of rodent HER2 was developed. Positive effects in HER2-transgenic BALB/c mice and wild-type BALB/c mice has led to an in-progress clinical trial in patients with advanced metastatic HER2+ tumors who have failed other therapies.

    Jill Weimer, PhD

    Senior Director of Therapeutic Development at Sanford Research

    Associate Scientist in the Pediatric and Rare Diseases Group at Sanford Research


    The fatal, primarily childhood, neurodegenerative disorders known collectively as neuronal ceroid lipofuscinoses (NCLs) are currently associated with mutations in 14 genes. The protein products of these genes (CLN1 to CLN14) differ in their function and their intracellular localization. NCL-associated proteins have been localized mostly to lysosomes (CLN1, CLN2, CLN3, CLN5, CLN7, CLN10, CLN12, and CLN13) but also the endoplasmic reticulum (CLN6 and CLN8), or in the cytosol associated to vesicular membranes (CLN4 and CLN14). Some of them, such as CLN1 (palmitoyl-protein thioesterase 1), CLN2 (tripeptidyl-peptidase 1), CLN5, CLN10 (cathepsin D), and CLN13 (cathepsin F), are soluble lysosomal proteins; others, like CLN3, CLN7, and CLN12, have been proposed to be lysosomal transmembrane proteins.


    This presentation will examine mouse models and recently developed porcine models for many of these NCLs that have facilitated therapeutic studies leading to clinical trials. As our understanding of the pathology of these diseases advances, identifying the right collaborators to execute understanding disease mechanisms, performing preclinical studies, and moving to clinical trials will be critical.

    The Translational Medicine Guide: “Asking the Right Question at the Right Time"

    Laetitia Devy-Dimanche, PhD

    Head of Global Project Management, EMD Serono, Inc.


    EMD Serono’s Translational Medicine Guide (TxM guide) has been developed to help each project team maximize success in achieving clinical proof of concept (cPoC) by considering multiple aspects of drug discovery and development. The TxM guide is a forward-looking strategic planning framework for teams to ask “the right questions at the right time.”


    This presentation will lay out the three primary goals of the TxM guide: (1) to identify the right biological target for the selected disease, (2) to identify the right molecule that delivers the right exposure at the target site of action and elicits the desired target modulation over the stated time period, without compromising patient safety, and (3) is to identify the right patient group in the selected disease. The speaker will then outline how the TxM guide helps teams to build a body of scientific and medical evidence to be better positioned to achieve positive cPoC.

    Neurimmune’s Reverse Translational Medicine Platform: Development of Human Antibodies
    for the Treatment of Protein Aggregation Diseases

    Jan Grimm, PhD

    Chief Scientific Officer, Neurimmune Holding AG

    Will not be streaming live


    Abnormal folding and aggregation of endogenous proteins in the brain or peripheral tissues characterizes many degenerative diseases, including Alzheimer’s and Parkinson’s disease, amyotrophic lateral sclerosis, and type 2 diabetes. The abnormal protein aggregates are stable; they can be involved in cell-to-cell propagation of pathology and can adopt conformations with cytotoxic activities. The presence of plasma antibodies against such misfolded proteins suggests active humoral immune responses, along with the formation of B cell memory.


    In this presentation, the speakers will detail their the hypothesis that selected B cell clones triggered by neoepitopes of pathological protein conformations encode antibodies that can block the toxicity and promote the clearance of protein aggregates. To test this hypothesis, the memory B cell repertoires of a large cohort of healthy aged human donors were analyzed, including donors with disease risk and abnormally slow progression or onset. Based on these analyses, the research team generated recombinant high-affinity human monoclonal antibodies that can be effective in neutralizing toxicity, blocking cell-to-cell propagation, and triggering the removal of protein aggregates by microglia or macrophage-mediated phagocytosis. Recent study results will be reviewed.

    Improving Translational Animal Models of CNS Disease – The Critical Role of New Technologies

    Antti Nurmi, PhD

    Managing Director, Charles River


    This presentation will offer an overview of established animal models of CNS diseases, their key properties, and how well they model human disease. Issues related to interpretations in animal behavior studies will be addressed, along with how valid interpretations mimic human symptoms and behaviors. The speakers will also explore novel methods that help build translational bridges between mice and men, in turn, improving confidence in the preclinical data to increase translatability to the clinic. These examples include clinically applied imaging techniques, such as positron emission tomography (PET), magnetic resonance imaging (MRI), as well as more advanced animal behavioral techniques such as touch screen operant assays and kinematic motion analysis. Attendees will also learn how multi-model studies in the rodent brain led to the discovery of vascular and metabolic anomalies of the liver, which has serious implications for biomedical research beyond CNS disease research.

    Patient in a Dish – Non-alcoholic Steatohepatitis (NASH) and Beyond

    Ryan Feaver, PhD

    Program Leader, NASH at HemoShear Therapeutics, LLC


    Non-alcoholic fatty liver disease (NAFLD) is a rapidly emerging public health crisis, affecting up to one-third of the US population, and can progress to non-alcoholic steatohepatitis (NASH) and cirrhosis, often resulting in liver transplant or death. This is one of the most active areas in drug discovery with over 40 drugs in the preclinical and clinical phase of development, but none to date have advanced beyond phase III clinical trials or been approved for therapy. The field is hampered by a lack of disease understanding and overreliance on >40 rodent models unable to map to the human response.


    This presentation introduces an in vitro approach that combines primary human hepatocytes, stellate cells, macrophages, a physiologically relevant tissue microenvironment consisting of liver sinusoid hemodynamic and transport conditions, and clinically-derived concentrations of NASH risk factors to create “NASH in a dish.” To date, the in vitro human NASH model has been used to survey the current drug development landscape in order to understand the therapeutic gaps, providing the principal data set to identity new targets for NASH therapies. Future research applications will also be discussed.

    Metastatic Breast Cancer Explored in a Human, 3D, Microfluidic Liver Chip

    D. Lansing Taylor, PhD

    Director, University of Pittsburgh Drug Discovery Institute, Allegheny Foundation; Professor of Computational and Systems Biology, University of Pittsburgh


    This talk will provide an overview of quantitative systems pharmacology (QSP), an integrated and iterative computational and experimental approach to drug discovery, that was recently implemented in several drug discovery programs. Specifically, the speaker will discuss the evolution of a human, 3-D, 4-cell type, microfluidic, liver microphysiology system (MPS) as a key experimental component of the institution’s metastatic breast cancer and liver disease programs.


    Metastatic breast cancer involves intravasation, extravasation and “seed and soil” growth establishment in the target organ. Initial studies are being investigated in the human liver MPS by exploring the seed and soil growth and drug sensitivity using the wild-type estrogen receptor alpha (ESR1) and two of the most common mutations, D538G and Y537S, in comparison to experiments performed in 2-D, where the research team explored distinguishable phenotypes that these mutations may confer using genome-editing methods. Results from completed and in-progress studies will be reviewed.

    Microvessel-Based 3D Assays of Angiogenesis

    James B. Hoying, PhD, FAHA

    Chief of the Division of Cardiovascular Therapeutics at the Cardiovascular Innovation Institute and President & CEO of Angiomics, Inc.; Chief Scientist, Advanced Solutions Life Sciences, University of Louisville


    Tissue health and disease involve complex interactions between the microvasculature, stroma, and parenchyma of the tissue. The microvasculature itself requires a dynamic interplay between vascular and perivascular cell types to maintain proper form and function.


    In this presentation, the speaker will discuss a versatile, enabling assay platform uniquely positioned to assess an integrated angiogenesis response in a complex environment. Involving the use of intact, isolated human microvessels in a 3-D stromal environment, the assay platform recapitulates native angiogenesis for use in phenotypic screens of different neovascular behaviors. The system is based on bona fide angiogenic sprouting and neovessel growth from isolated, intact parent microvessels that retain all intrinsic vascular and perivascular cells within a 3-D matrix environment. This model system has been effectively used to identify and characterize putative angiogenic factors and inhibitors, evaluate microvascular instability, and define tissue dynamics during angiogenesis. It is compatible with high-content analysis modalities and has a proven utility in a variety of research and pharmaceutical applications. In addition, the microvessels are showing promise in regenerative medicine and tissue fabrication as a promising vascularizing solution.

    A Unifying Model to Explain Primary and Compensatory Immune Resilience of Cancer

    Francesco Marincola, MD, FACS

    Distinguished Research Fellow in Immuno-Oncology, AbbVie


    Available data suggest that three landscapes best portray the cancer microenvironment: an immune-active, an opposite immune-deserted, and an intermediate immune-depleted. This trichotomy is observable across most solid tumors, suggesting that convergent evolutionary adaptations determine the survival and growth of cancer in the immune competent host. The mechanisms allowing persistence of cancer in the immune-active cluster are referred to as compensatory immune resistance (CIRes). Conversely, survival of cancer in the immune-silent environment is referred to as primary immune resistance (PIRes).


    To explain CIRes and PIRes, several models have been proposed that largely outnumber the fewer immune landscapes. In this presentation, the speakers will share how they the research team came to build a navigational map of cancer to assign distinct immune-resistance models to the respective immune-landscape. The survey confirmed that immune suppression strictly goes hand-in-hand with immune activation in the favorable landscape, while the silent landscape is characterized by lack of immune modulation and by a lean oncogenic process that permits growth without activation of the host’s defense mechanisms.

    A Diet-Induced Animal Model of Nonalcoholic Fatty Liver Disease

    Arun Sanyal, MD

    Professor, Department of Internal Medicine, Division of Gastroenterology, Virginia Commonwealth University


    Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease and a growing indication for liver transplantation for end-stage liver disease as well as liver cancer. There are currently no approved therapies for nonalcoholic steatohepatitis (NASH). While a large number of therapeutic targets have been identified, there is a need for viable preclinical animal models that recapitulate all stages of NASH development and progression, and that recapitulate the human disease with respect to inducers, liver histology, activation of pathways known to be relevant to human disease, and a transcriptomic profile similar to that in humans.


    This presentation introduces a model where the phenotype was originally noted in a B6129SF2/J mice family and which is now shown to meet the above noted criteria in a consistent manner through brother-sister inbreeding to create an isogenic mouse strain. Study data indicate that this mouse captures the key elements of human disease and provides a tool to better understand the inter-relationships between pathways with disease progression, and to test the therapeutic potential of individual or combination therapies for related disease.

    Fitness Impacts Susceptibility for Obesity and Metabolic Disease

    John P. Thyfault, PhD

    Associate Professor of Physiology, University of Kansas


    High or low aerobic capacity/fitness status significantly impacts mortality and susceptibility for metabolic diseases such as fatty liver and diabetes, but the mechanisms remain unknown. The ramifications of this knowledge gap are profound for developing treatment strategies as patients are increasingly sedentary with very low aerobic capacity. We utilize rats selectively bred for high (HCR) and low (LCR) intrinsic aerobic capacity over several generations to examine the mechanisms by which aerobic capacity impacts metabolic vulnerability for fatty liver, insulin resistance, and obesity, following acute and chronic high fat diets. HCR rats live longer than LCR rats and are less susceptible to cognitive impairment, cardiovascular disease, and cancer. Our studies have shown that there are key differences in regulation of energy balance, substrate utilization and trafficking, and metabolic flexibility that all likely play a role in the low fit LCR rats being more susceptible to obesity and metabolic dysfunction. Emerging evidence suggests that these divergent phenotypes are driven by large differences in “hepatic mitochondrial function”, defined as respiratory capacity, fatty acid oxidation, and energy state. Low fit LCR rats have compromised hepatic mitochondrial function that is further worsened following high fat diet-induced hepatic steatosis. In contrast, HCR rats maintain mitochondrial function and are protected against the development of dietary induced steatosis.  In addition, chronic high fat diets with 1% cholesterol, which is commonly used to evoke steatohepatitis, show that the LCR develop significant hepatic inflammation, necrosis, and apoptosis, while the high fit HCR animals appear relatively protected despite hepatomegaly occurring in both groups. Recent data suggests that hepatic energy state, modulated by fatty acid oxidation, impacts energy intake through as of yet unknown mechanisms. In addition, aerobic capacity status also dramatically impacts histone acetylation profile and hepatic transcriptional adaptability. In conclusion, these studies are beginning to reveal mechanisms by which low fitness, through hepatic differences in metabolism, impact susceptibility and treatment strategies for obesity and metabolic disease.

    Diet Preferences in Large Animal Models of Cardiovascular Disease: Does it Matter?

    Anthony G. Comuzzie, PhD, FTOS

    Executive Director, The Obesity Society


    Most of the animal-based research related to diet and risk associated with cardiovascular disease, obesity, and diabetes has focused primarily on the impact of specific dietary fats. While these efforts have recently expanded to examine the impact of carbohydrates and proteins, the potential contribution of overall palatability on the feeding behavior of research animals has largely been ignored. Data from multiple feeding studies that have been conducted in the baboon suggest the importance of considering palatability in the development of dietary challenges to investigate the impact of nutritional components on cardiometabolic health.


    This presentation will review the speaker’s research, which indicates that the research animals’ pattern of consumption, an important component in the mechanism of nutritional impact on disease risk, may vary depending on the palatability of the diet. The researchers have found that by increasing the palatability of challenge diets, simply by adding fruit flavoring and baking, they can obtain a pattern of consumption that is most likely more like that seen in humans, and as a result more successfully drives the development of the clinical manifestations of interest.

    Small Molecule Discovery for Regenerative Medicine: The Essential Role of
    Non-Traditional Animal Models

    Kevin Strange, PhD

    Novo Biosciences


    Regenerative medicine is the field of biomedical R&D and clinical practice focused on repairing, regenerating, or replacing tissues and organs that have been lost or damaged due to injury, disease, and the degenerative changes associated with aging. The discovery and development of small molecules capable of activating innate tissue repair and regenerative processes is a newly emerging field in regenerative medicine. Arguably, the most economical and efficient strategy for development of small molecules with regenerative medicine applications is to use “non-traditional” animal models for both target- and phenotype-based drug discovery.


    Novo Biosciences, Inc. and the MDI Biological Laboratory have undertaken a focused effort to develop lead small molecules capable of activating endogenous tissue regenerative mechanisms. These efforts are greatly facilitated by RegenDbase, a unique computational biology and bioinformatics tool, as well as the use of the zebrafish for phenotype-based small molecule screening and discovery. This presentation will examine the discovery and characterization of MSI-1436, the first and, to date, only small molecule capable of inducing regeneration in the adult mammalian heart following ischemic injury.

    Bugs as Drugs

    Kip West, PhD

    Director, Pharmacology, Synlogic


    Inborn errors of metabolism (IEM), which include diseases such as urea cycle disorders (UCD), phenylketonuria (PKU) and maple syrup urine disease (MSUD), are rare genetic diseases in which defects in enzymes (or pathways) involved in nutrient metabolism result in the inability to convert food products into proteins, alternative essential factors or energy. Such deficiencies in substrate conversion lead to either a build-up of toxic metabolites or lack of an essential compound. While these diseases individually are rare, collectively they represent a large unmet medical need due to the potential threat of mortality that accompanies the metabolic decompensation events characteristic of these diseases, as well as the cognitive and behavioral symptoms that significantly impair the daily lives of these patients. Unfortunately, the current treatments for IEM are either marginally efficacious or non-existent. Moreover, people suffering from these diseases endure life-long dietary restrictions which include low-protein prescription diets. Regrettably, low levels of dietary protein can lead to a failure to thrive, and lifelong compliance with such restrictive diets is challenging.


    At Synlogic we are using synthetic biology in combination with natural probiotics to develop engineered bacteria or Synthetic BioticTM Medicines, which are programmed to perform metabolic conversions to compensate for missing pathways such as those found in IEM patients. To this end, we have employed a probiotic bacterial strain, E. coli Nissle, as our platform or “chassis” and using synthetic biology have generated engineered strains capable of efficiently consuming toxic metabolites specific to different IEM disorders and to lower systemic levels of the toxins.


    In our lead program in UCD, we have developed a strain that is highly effective at consuming ammonia in vitro. When tested in a mouse model of UCD, this strain demonstrated significant blood ammonia-lowering activity and a survival benefit compared to controls. In addition, our clinical candidate strain has demonstrated safety in both mouse and nonhuman primate toxicology studies at multiples several fold above the predicted human dose.


    In our PKU program, we have engineered the Nissle chassis to take up phenylalanine (Phe) with high affinity and efficiently metabolize it into a nontoxic by-product. In vitro studies demonstrate that our PKU strain degrades Phe at a high rate compared to the parental Nissle strain. Moreover, this in vitro metabolic activity translated to in vivo activity where, in the enu2 mouse model of PKU, oral administration of the strain was able to blunt hyperphenylalaninemia (an increase in blood Phe) compared to controls. Importantly, we have also demonstrated dose-dependent production of a strain-specific biomarker associated with the engineered Phe degradation mechanism in nonhuman primates, a more physiologically relevant animal model.


    Finally, for MSUD, we have created a strain that demonstrates high in vitro breakdown of the branch chain amino acid leucine (the predominant toxic metabolite underlying this disease), and was also capable of lowering both blood and brain leucine levels and improving neurological function in vivo in a mouse model of intermediate MSUD (iMSUD).


    In conclusion, we are creating novel medicines called “Synthetic Biotic Medicines” for the treatment of different diseases through the combination of synthetic biology and probiotics.  We have developed Synthetic Biotic Medicines for several different IEM that can reduce systemic levels of the toxic metabolites associated with these diseases in disease-relevant animal models. We believe that Synthetic Biotic Medicines have the potential to provide new therapeutic options for patients in several IEM and we are advancing these living medicines through preclinical and clinical development with the goal of significantly impacting the quality of patients’ lives.

    Rapid 3D Bioprinting of Blood Vessel Network and Microphysiological Systems

    Shaochen Chen, PhD

    Professor, University of California, San Diego


    This presentation will review the speakers’s recent research efforts in rapid continuous projection 3-D bioprinting to create 3-D scaffolds using a variety of biomaterials. These 3-D biomaterials are functionalized with precise control of micro-architecture, mechanical, chemical, and biological properties. Such functional biomaterials allowed for investigation of cell-microenvironment interactions at nano- and micro-scales in response to integrated physical and chemical stimuli. From these fundamental studies, both in vitro and in vivo microphysiological systems can be created, including a human liver tissue for tissue regeneration, disease modeling, and drug discovery.


    To vascularize these engineered tissues, the researchers have developed a prevascularization technique using the rapid 3-D bioprinting method. With regionally controlled biomaterial properties, the endothelial cells formed lumen-like structures spontaneously in vitro. In vivo implantation demonstrated the survival and progressive formation of the endothelial network in the prevascularized tissue. Anastomosis between the bioprinted endothelial network and host circulation was observed with functional blood vessels featuring red blood cells. With superior bioprinting speed, flexibility and scalability, this new prevascularization approach can be broadly applicable to the engineering and translation of various functional tissues.

    Atherosclerosis is the underlying cause of cardiovascular events and the major cause of morbidity and mortality in developed countries. The bulk of contemporary atherosclerosis literature is focused on mouse models performed in mice lacking either LDL receptor or ApoE. While these studies have determined potential therapeutic targets, there are limited examples of targets identified or validated in mouse models that have subsequently led to human interventions. A major shortcoming of common animal models is their failure to develop atherosclerosis that accurately mimics lesions in advanced stages and to recapitulate acute thrombotic events associated with atherosclerosis that trigger overt clinical symptoms.


    Aortic aneurysms are less common than atherosclerotic diseases, but represent an area of considerable unmet medical need. In this presentation, the speaker will review three common mouse models of abdominal aortic aneurysms and discuss how a lack of information on the natural history of the human disease hinders the determination of the fidelity of these animal models. Discussion will include current clinical trials and their potential role in increasing the diminutive number of therapeutic targets for these diseases.

    Rat Models of Susceptibility to Complex Diseases: A Solution to Eroom’s Law

    Steven Britton, PhD

    Professor of Anesthesiology, Professor of Molecular and Integrative Physiology, University of Michigan


    Since 1950, the inflation-adjusted industrial development costs per drug increased nearly 100-fold to arrive at 1 billion dollars. This trend, termed Eroom’s Law (i.e., Moore’s Law backwards), is an enigma because huge high-throughput technological gains should have raised the efficiency of research and development (R&D). A recent quantitative decision-theoretic model of the R&D process led to the conclusion that Eroom’s is explained by: 1) limited creation and use of valid animal models of disease, and 2) too much reliance on reductionist molecular approaches that are devoid of the very complexity that embodies emergent disease conditions.


    This presentation will offer an alternative – an integrative, theory-based, approach to resolving complex diseases that builds upon an evidenced link between low exercise capacity and high morbidity and mortality. Attendees will learn about a predictive test of this hypothesis, which demonstrates that two-way selective breeding of genetically heterogeneous rats for low and high intrinsic treadmill running capacity (used as a surrogate for energy transfer) also produces rats that differ for risk of obesity, diabetic neuropathy, metabolic syndrome, and reduced longevity.
