Department of Population Health and Reproduction
Our current and future research plans are directed towards elucidating the molecular basis of inherited diseases in companion animals. We are interested in developing tests to help breeders eliminate inherited diseases in dogs and horses. A large number of the diseases seen in veterinary practice that affect purebred animals have a heritable basis.
Characterizing inherited disease in dogs has the added benefit of providing an animal model for human diseases. Presently we have projects in both horses and dogs. We are working on the molecular basis of chronic progressive lymphedema in horses and susceptibility to pneumonia in horses. In dogs we are working on the molecular basis of Addison’s disease, cleft palate, Intervertebral disc disease, myopia, vertebral spinal malformations and longevity. My laboratory has identified the mutations responsible for lethal white foal syndrome (LWFS), HERDA, and Hoof wall separation syndrome (HWSS) in horses and hyperuricosuria (HUU), spinal disraphism (SD), Juvenile Addison’s disease (JADD), Alaskan Husky encephalopathy, Saluki encephalopathy, chondrodystrophy, glioma susceptibility, cleft lip, palate and syndactyly (CLPS) and cleft palate (CP1).
I welcome STAR students interested in genetic diseases.

Veterinary Genetics Laboratory
Dr. Bellone is a molecular geneticist whose research interests include elucidating the genetics of economically and medically important traits in the horse as well as traits that serve as models for other species. Current projects in horses involve investigating the genetic and molecular basis of several ocular disorders and in some cases associated pigmentation phenotypes. Recently her laboratory discovered the genetic risk factor for the second most common tumor of horses, ocular squamous cell carcinoma. Other findings include identifying the genetic mechanisms for congenital stationary night blindness in multiple horse breeds, as well as distichiasis in Friesian horses. Currently her collaborative research team is trying to identify the genetic risk factor for equine recurrent uveitis, the leading cause of blindness in horses, among other projects. The primary research goal is to develop DNA diagnostic tests that assist animal breeders in making informed mating decisions and work towards better clinical management practices, by understanding the biological mechanisms behind complex heritable traits. Dr. Bellone is passionate about training and working closely with students in her laboratory to assist them in making significant contributions to these projects.

Given the diversity of pathologies for which mitochondrial dysfunction is implicated, transformative approaches are needed to investigate disease pathogenesis, improve diagnosis, identify prognostic biomarkers, and generate novel treatment strategies. For the first time, we aim at creating a database in VetMed by leveraging our own clinical and research as well as those published in peer-reviewed Journals to consolidate a broad range of mixed phenotypes associated with mitochondrial disorders and dysfunction. The complete, thorough mitochondrial phenotyping platform will include datasets composed of available data (e.g., multi-omics data, mitochondrial function readouts, genetics, and quantitative imaging mitochondrial morphology descriptors) from different species to promote knowledge among clinicians and faciliate diagnosis of mitochondrial disorders in animals.

Tendon repair, stem/progenitor cell biology
College of Agriculture and Environmental Sciences (See also: Orthopaedics/Biomechanical Engineering, Biochemistry/Cellular Biology, and Translational Research)
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

(See also: Epidemiology, Food Animal Medicine/Food Safety, Microbiology/Parasitology)
Dr. Pereira research focuses on evidence based medicine on antimicrobial resistance in livestock and judicious use of antimicrobials through interventions that promote livestock health and well-being. Maintaining the effectiveness of antimicrobial drugs to treat infections is of relevance to the health of both animal and human populations. Recent project investigated enteric microbiota of calves using metagenomic sequencing approaches, and herd management impacts on prevalence of resistant enteric bacteria, including evaluation of drug use, feeding practices, and housing management of dairy calves and heifers.
Epidemiology is the foundation of his research which also employs statistics, microbiology, and molecular and genomic approaches. Using these tools, some current research projects include investigating and identifying risk factors for selection and spread of antimicrobial resistance in Salmonella from livestock, and investigating impacts on drug resistance and animal health from feeding pre-weaned calves waste milk (milk containing drug residues) with the aim of identifying interventions to reduce unwanted impacts from this practice.
Previous projects accomplished include:
Spatial-temporal trends in antimicrobial resistant Salmonella isolates recovered from Northern California dairy cattle at a veterinary microbiology laboratory between 2002 and 2017.
Potential 10 week projects for Summer 2018:
Antimicrobial resistance in bacteria causing metritis in dairy cows.
Evaluation of on-farm factors affecting antimicrobial drug on the dairy farms.

(See also: Neurology/Neurobiology, Translational Research, Biochemistry/Cellular Biology)
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.
