PROJECT SUMMARY/ABSTRACT – UCSF LIVER CENTER The Liver Center of the University of California, San Francisco (UCSF) is an interdisciplinary consortium of 59 basic and clinical scientists dedicated to understanding liver biology and contributing new knowledge about the pathophysiology and treatment of liver diseases. The overarching theme of the center is “translating science to benefit patients with liver disease.” The Center's research base is made up of 40 individuals: these investigators receive $21 million dollars in liver-related research funds annually (direct costs). The research base of the Center is evenly split between practicing physicians and non-physicians. Their research is categorized into three focus areas. One focus area is entitled Liver Injury, Repair & Transplantation: this group includes scientists who study liver immunology as well as clinician-investigators who study the epidemiology, management and outcomes of chronic liver disease. Second is Liver Cell Biology, Plasticity & Transformation: this area is home to scientists who study cellular responses to liver injury such as toxicity and fibrosis, as well as cell growth in contexts ranging from developmental biology to cancer. Third is Hepatic Metabolism & Metabolic Derangements: members in this category study basic aspects of nutrient and xenobiotic metabolism as well as the mechanisms, diagnosis and outcomes of fatty liver disease. Across all focus areas, research spans bench to bedside. More than 75% of Center members perform research directly with human subjects or human materials. A major goal of the Liver Center is to promote research excellence and accelerate research progress in hepatology. As it continues in 2018-2023, the Center will accomplish this goal by supporting three Biomedical Research Cores: (1) Cell Biology, (2) Liver Immunology & Cell Analysis and (3) Pathology & Imaging. The Center also operates a separate Clinical Component, which offers biostatistics services and is being expanded to include support for biospecimen procurement, storage and retrieval. A second goal of the Liver Center is to foster a vibrant community of liver researchers at UCSF. In this case the strategy will be to stimulate scientific exchange through an Enrichment Program that features seminars by local and visiting scientists, mini-symposia highlighting specific member constituencies, and an annual 1-day symposium featuring the progress of the entire group. Throughout the year the Center's Administrative Core will maintain member connections and keep them informed of new developments through newsletters and a comprehensive website. A third goal of the Center is to sustain a trajectory of growth in liver research by developing promising new investigators. Several means will be used to achieve this end. First, the Center will continue its Pilot/Feasibility Program, which provides seed money to junior investigators and scientists new to investigative hepatology. This award program is...
