Osteoimmunology (see also: biochemistry, dermatology, immunology and osteoimmunology)
Our laboratory studies the interface between the skeletal and immune systems, a newly emerging area of research called “osteoimmunology”. Haematopoietic stem cells in the bone marrow give rise to both T cells which are important in inflammation and osteoclasts that regulate bone resorption. Differentiation and activation of osteoclasts from their precursors is tightly regulated by cytokines and growth factors such as receptor activator of nuclear factor kappa beta (RANKL), tumor necrosis factor (TNF) and various interleukins. Receptor engagement of these molecules results in signaling cascades and transcriptional changes that give rise to medical conditions such as rheumatoid arthritis, osteoporosis and osteopetrosis. Using in vivo gene transfer of immune cytokines IL-23 and IL-17, we have established new arthritis animal models that highlight the importance of these immune cytokines in arthritis initiation and bone homeostasis. Using in vitro assays, we continue our attempts to define the cellular and molecular mechanisms that take place in this fascinating interplay of the immune and skeletal systems.

Our highly translational research program is actively investigating the regulation of energy homeostasis and carbohydrate/lipid metabolism, and involvement of endocrine systems in the pathophysiology of obesity, diabetes, and cardiovascular disease. My laboratory is studying the mechanisms regulating the secretion of pancreatic and gastrointestinal, and adipocyte hormones. The role of endocrine, metabolic, and dietary factors in regulating energy balance, insulin action, and lipid/carbohydrate metabolism is studied in animal models (rodents and nonhuman primates) and humans. We are conducting studies on the prevention and treatment of diabetes in a rat model of type 2 diabetes developed in our laboratory (UCD-T2DM Rat) that is more similar in pathophysiology to type 2 diabetes in humans than other available models (Am. J. Physiol., 2008). We have used the UCD-T2DM model for 15 additional published studies on the pathophysiology of T2DM and for investigating pharmacological and surgical approaches for the treatment and prevention of T2DM. We have been involved in clinical studies and experiments in animal models investigating the effects of bariatric surgery procedures on how these endocrine changes are involved in improvements of carbohydrate and lipid metabolism and the resolution of type 2 diabetes observed after surgery. Another major focus of the research is the role of diet composition (such as dietary fat and fructose) in the development and progression of obesity, diabetes, and dyslipidemia including studies in animal models and clinical studies in humans. In addition, our laboratory has been conducting translational studies funded by the NIH, ADA, and pharmaceutical/ biotechnology industry sources at the California National Primate Research Center in a diet-induced rhesus monkey model of metabolic syndrome with insulin resistance and dyslipidemia (Clinical. Trans. Sci., 2011, ILAR Journal, 2017) as extensions of our studies in rodent models and as preclinical investigations that generate data and hypotheses that are then tested in clinical studies in humans. We have demonstrated that consumption of fructose, but not glucose-sweetened beverages for 10 weeks increases visceral adiposity and lipids and decreases insulin sensitivity in humans (J. Clin. Invest., 2009). We also recently completed a comprehensive NIH-funded dose-response study of the metabolic effects of sugar- sweetened beverages (Am. J. Clin. Nutr., 2015) and are currently studying the metabolic effects of dietary sugars under ad libitum versus energy-balanced conditions.

Tendon repair, stem/progenitor cell biology
College of Agriculture and Environmental Sciences (See also: Orthopaedics/Biomechanical Engineering, Genetics/Genomics and Genetics/Genomics)
My primary research interests include:
(1) the development, maturation, and repair of musculoskeletal connective tissues like tendon and ligament
(2) cellular mechanisms behind broiler muscle pathology
(3) the roles of the microbiome in proper gut transition in foals from birth to weaning.
In my musculoskeletal research projects, I am particularly interested in how differences in niche affect cells within the environment in growth and repair. Moreover, I am interested in the physiology of usage and elite performance as well as pathophysiology from over-usage, acute and chronic injury for all musculoskeletal tissues on all species as they might be related to use, environment, or genetics, and as they might be related to the manipulation of niche and collagen regulation genes. Furthermore, because the proper development of the musculoskeletal system depends greatly upon proper foal growth and foal growth subsequently depends upon appropriate nutrition, I am interested in understanding how gut microbes facilitate healthy gut transitions in the foal.More information can be found at: http://animalscience.ucdavis.edu/faculty/mienaltowski/index.html

Research in the Segal Lab revolves around engineering zinc finger, TALE, and CRISPR/Cas nucleases and transcription factors. Almost every disease has a genetic component. Often this information is used only to determine how condemned a person is to develop disease. We would like to use the genetic information to fix the disease. A guiding principle for our work has been to study how nature does what it does, then attempt to use that knowledge to make useful tools to improve public health. We continue to develop new methodologies for genome editing. Our most recent efforts focus on creating epigenomic editing tools that can precisely manipulate epigenetic information at specific loci. Such tools can be used for the long-term control of gene expression for both research and therapeutic applications. Angelman syndrome is a rare neurogenetic disease that is the textbook example of an imprinting disorder. We are using artificial transcription factors to activate the epigenetically silenced gene in in the brains of mice and other animal models.

My name is Aijun Wang. I am an assistant professor at the Department of Surgery, School of Medicine. My research interests center on engineering stem cells and biomaterials to develop novel regenerative medical therapies, especially surgical treatments for congenital anomalies. Since my employment as Co-Director of the Surgical Bioengineering Laboratory and an Assistant Professor at the University of California Davis School of Medicine in 2012, my lab has successfully combined tissue-engineering technologies with the most advanced fetal intervention, and developed novel biomaterial and stem cell-based treatments (including nanofibrous materials, fetal membrane, decelluarized extracellular matrix, iPSC-derived stem cells, placenta-derived stem cells) for devastating structural and genetic birth defects, such as spina bifida, hemophilia and congenital diaphragmatic hernia. Currently, we are extensively using the mouse, rat, guinea pig, rabbit and sheep experimental models to develop novel regenerative therapies. We are also adapting these novel therapies we developed in the lab for the treatment of naturally occurring diseases in companion animals.
