8th Annual SBP Rare Disease Day Symposium
The annual Rare Disease Day Symposium at Sanford Burnham Prebys Medical Discovery Institute (SBP) seeks to serve patients and families affected by rare genetic diseases.
The 2017 SBP Rare Disease Day event, scheduled to be held Friday, February 24, 2017 at the SBP campus in La Jolla, CA, will be the first scientific conference focusing specifically on Alagille Syndrome.
Alagille Syndrome (ALGS) is a rare genetic disorder that can affect the liver, heart, and other parts of the body. It is estimated that 1 in 30,000 infants are born with ALGS. The severity of the disorder ranges from mild to patients who need liver transplants.
Expert talks at the 2017 meeting will provide particular emphasis on:
- biliary paucity
- genetic mechanism
- Notch signaling
- biliary development/regeneration
Scientists, clinicians, advocates, patients and their families are invited to join experts in the ALGS field to foster new perspectives, ideas, and collaborations and accelerate efforts toward a cure for Alagille Syndrome.
Registration opens at 8:00 a.m.

Jagged signaling in biliary development, disease, and regeneration
Assistant Professor, Human Genetics Program
Sanford Burnham Prebys Medical Discovery Institute
Dr. Dong received his Biology Bachelor of Science degree in 1996 from the University of California, Irvine, where he was involved in molecular evolution and limb regeneration research. He earned his Ph.D. in Cell and Molecular Biology investigating master control genes and tissue lineage regulation at the University of Wisconsin, Madison in 2002. He did his postdoctoral research at the University of California, San Francisco, where he focused on developmental genetics of the liver and pancreas. Dr. Dong was recruited as an Assistant Professor to Sanford Burnham Prebys Medical Discovery Institute in 2008. He is a recipient of the NIH Director’s New Innovator Award, which funds the development of in vivo lineage conversion technologies to generate replacement cells and organs within a living vertebrate. His vision is to make in vivo lineage reprogramming a practical strategy for regenerative medicine. His lab’s underlying approach is to gain basic and biomedical insight through rigorous investigation of the genetic mechanisms governing organogenesis, diseases, and cell lineage commitment/conversion. They have discovered multiple genes critical for lineage specification of liver and pancreas progenitors and have developed several in vivo models for diseases such as early onset diabetes and Alagille Syndrome. Most recently, they discovered a way to reprogram differentiated cells to adopt a completely unrelated identity, without having to remove them from the body. Dr. Dong’s ultimate goal is to determine how gene function can be manipulated to help cure diseases and advance regenerative medicine.

Dr. Joan Font-Burgada received his Ph.D. degree in Genetics from the University of Barcelona, where he studied the histone code using Drosophila HP1 proteins as a model. For his postdoctoral studies, he moved to Michael Karin’s lab at UCSD and became interested in liver regeneration and cancer development. As a CIRM postdoctoral scholar, he identified a new subpopulation of hepatocytes, Hybrid Hepatocytes (HybHP), with a pivotal role in the repair of the injured liver. He recently obtained an NCI K99/R00 award to generate mouse models that replicate the complexity of human hepatocellular carcinoma genetics. He is starting his own laboratory in 2017 as an Assistant Professor at the Fox Chase Cancer Center in Philadelphia to delve into the mechanisms of liver regeneration and liver cancer development.
Making ducts from hepatocytes
Director, Oregon Stem Cell Center
Director, Pape Family Pediatric Research Institute
Ray Hickey Chair, Oregon Health & Science University
Dr. Grompe received his medical degree (Dr. med.) in 1983 at the University of Ulm Medical School in Germany. His interest in Human Genetics started with a one year research project abroad during medical school. From 1984-1987 Dr. Grompe was trained in Pediatrics at Oregon Health Sciences University in Portland, Oregon, USA and then moved to Baylor College of Medicine in Houston, Texas. There he was a fellow sponsored by the Pediatric Scientist Training Program in the Institute for Molecular Genetics from 1987-1991 and worked on gene therapy for inherited diseases, particularly metabolic liver disorders. In 1991, Dr. Grompe joined the faculty at Oregon Health & Sciences University and he is currently Professor in the Departments of Pediatrics and Molecular and Medical Genetics.
In 2002 he received the most prestigious award for Pediatric Research in the United States, the E. Mead Johnson Award. In same year he was given the Merit Award of the Fanconi Anemia Research Foundation. In 2007 he was chosen for the Oregon Medical Research Foundation Discovery Award.
Dr. Grompe is involved in the clinical care of patients with genetic diseases as well as scientific investigation. In 2004 he became the first director of the newly founded Oregon Stem Cell Center. Since 2008 he is the holder of the Ray Hickey Chair and the first Director of the Papé Family Pediatric Research Institute.
His research has focussed on the use of in vivo selection to enhance gene and cell therapy, particularly stem cell therapy. The two model diseases being studied are hereditary tyrosinemia type 1, a childhood liver disease and Fanconi Anemia (FA), a blood disorder. In 1996, his laboratory showed that gene therapy in combination in vivo selection could be used to replace > 90% of cells in a diseased mouse liver. Since then, his work has focussed on the biology of intra- and extrahepatic liver stem cells and their use in therapeutic liver repopulation. His group developed a patented method to replace the cells of mouse livers with human hepatocytes. Recently, he discovered that hepatocytes are subject to the ploidy conveyor, making them genetically heterogeneous and highly aneuploid.
The Fanconi anemia pathway is involved in the maintenance of genomic stability and stem cell integrity in mammals. The Grompe Lab cloned a novel Fanconi Anemia gene, FANCD2, which has been shown to link the Fanconi Anemia pathway to BRCA1 and BRCA2, genes involved in familial breast cancer. Preclinical gene therapy experiments in murine models of FA have been used to demonstrate in vivo selection at the level of hematopoietic stem cells. Recently, the Grompe lab has discovered small molecules to prevent solid tumors in this disease.
Dr. Grompe holds several patents and is the Founder of Yecuris, Inc. a Portland-based start-up company dedicated to generating animals with humanized livers for life science research and cell therapy. He also co-founded the DNA Repair company, based in Boston, MA.
Molecular factors regulating hepatic cell identity
Associate Professor, Division of Gastroenterology, Hepatology & Nutrition,
Division of Developmental Biology
Cincinnati Children’s Hospital Medical Center
Stacey S. Huppert, Ph.D., is an Associate Professor of Gastroenterology, Hepatology and Nutrition at Cincinnati Children’s Hospital Medical Center and the University of Cincinnati College of Medicine. Dr. Huppert’s research program explores how intercellular signaling pathways are integrated to coordinate cell fate decisions and allocate cell types during both organogenesis and regeneration. She is specifically focused on the therapeutic potential of differentiated hepatocytes to augment or regenerate insufficient intrahepatic bile duct systems. Dr. Huppert’s work has established a three-dimensional blueprint for the formation of intrahepatic bile duct architecture which has earned the cover of Hepatology twice. She is involved in a multidisciplinary group, Solving Organ Shortage, whose mission is to advance research initiatives for regenerating liver or engineering livers for human transplant. Her collaborative efforts bridging investigators from multiple disciplines to tackle diseases due to bile duct insufficiency has been featured. Notch signaling is a specific focus of Dr. Huppert and one pathway that holds promise as a therapeutic target for treatment of many cancers and congenital diseases. Her work, demonstrating that proper cell fate decisions stem from Notch signaling imparting feedback regulation of ligand and receptor asymmetric expression, continues to be a central concept in canonical Notch signaling. Dr. Huppert combines cellular and biochemical screens with advanced methods to quantify three-dimensional changes of in vivo vascular and epithelial structures enabling the search for targets that fine-tune regulation of Notch pathway activity.
Modeling Jag1 haploinsufficiency in mice
Department of Molecular & Human Genetics
Baylor College of Medicine
Hamed Jafar-Nejad’s group is interested in the roles of glycosylation and deglycosylation in the regulation of animal development and in human disease pathogenesis. He received his MD from Tehran University of Medical Sciences and learned basic molecular biology techniques in a research institute in Iran. He spent one year in the Neuroscience Research Institute at the University of Ottawa, where he studied the transcriptional regulation of a serotonin receptor implicated in mood disorders. He then moved to Houston and performed his postdoctoral training in the area of Notch signaling and Drosophila neurogenesis with Dr. Hugo Bellen at Baylor College of Medicine. In December 2006, he joined the faculty at the University of Texas Health Science Center at Houston, focusing on a glycosyltransferase called Rumi, which they had identified in Drosophila as a key regulator of the Notch signaling pathway. In 2012, he was recruited back to Baylor, where his group continues their studies on the role of glycosylation in animal development. In recent years, Jafar-Nejad laboratory has devoted significant effort to understanding the function of human rare disease genes in animal development. In one project, the lab has established a mouse model for Alagille syndrome and has identified Rumi (Poglut1) as a dominant genetic suppressor of the Alagille biliary phenotypes in the mouse. In another project, they are using Drosophila to understand the developmental roles of a deglycosylation enzyme called N-glycanase 1 (NGLY1), mutations in which cause a multi-system developmental disorder called NGLY1 deficiency. It is hoped that these collaborative studies will shed light on the pathophysiology of these two diseases and will help identify new therapeutic approaches for them.

Notch signaling in nephron segmentation
William K. Schubert Professor of Pediatrics
Director, Division of Developmental Biology
Cincinnati Children’s Hospital Medical Center
Dr. Kopan has carried out seminal work in the field of Notch biology. This work has, and continues to have, an enormous impact on our understanding of normal tissue development and renewal, developmental syndroms, Alzheimer’s disease and cancer-related research. In deciphering the mechanism of Notch activation and demonstrating the use of inhibitors to modulate Notch activity, Dr. Kopan’s work laid the groundwork for the therapeutic use of g-secretase inhibitors in the treatment of cancers, currently in clinical trials. His current interests in organogenesis are focused on two modular organs- skin and kidney- in which his group is trying to understand how interplay among organs and the immune system shapes systemic responses to injury results and how Notch receptor activation contributes to distant programs in different organs. To that end Dr. Kopan is active in developing novel assays using these technologies to understand integration of Notch with other signaling pathways. Dr Kopan’s work resulted in 138 scientific articles, is the co-inventor of 1 patent, and is a sought-after consultant to the pharmaceutical industry.

Engineering microenvironments to study liver differentiation
Department of Bioengineering
University of Illinois at Urbana-Champaign
Gregory H. Underhill is an Assistant Professor of Bioengineering at the University of Illinois at Urbana-Champaign. Dr. Underhill received his PhD from Northwestern University, with his doctoral research focused on the mechanisms controlling the tissue recruitment of T lymphocytes and the functional characteristics of antibody secreting plasma cells. Dr. Underhill completed a postdoctoral fellowship in Dr. Sangeeta Bhatia’s laboratory at MIT, where he worked to develop and apply engineered cell culture platforms towards the study of cell functions. His current research is focused on studying cellular fate decisions, including the tissue development and engineering of the liver. These efforts are at the interface of cell and developmental biology, genomics, biomaterials, and microfabrication. Dr. Underhill’s lab has recently developed a cell microarray platform to enable the systematic analysis of liver progenitor cell fate specification within defined microenvironments, and in particular, facilitate the assessment of interactions between TGF beta, Notch, and other microenvironmental cues including extracellular matrix. These efforts suggest that mechanical signals may also play role in liver progenitor cell function, and that spatial patterns of cell mechanotransduction can cooperate with Notch and other signals to regulate differentiation.
