Study IDST000424
Study TitleMetabolomics Approach to Allograft Assessment in Liver Transplantation (part II)
Study TypeRetrospective analysis of biobanked liver tissue from organ donors
Study SummaryThis pilot study is designed to apply several types of metabolomic analysis for liver allograft assessment with the aim of identifying candidate biomarkers for allograft function and to develop a methodology that could be applied to larger scale studies. The three main categories of metabolomic analysis are reflected in each of the specific aims, including a targeted profiling of central carbon metabolism, open lipidomic and metabolomic profiling for hypothesis generation and MALDI-IMS for tissue-based spatial analysis. Each of these approaches offers potential benefits that could be optimized in a protocol for larger scale studies depending the results of the pilot investigations.

Project Title:Metabolomics approach to allograft assessment in liver transplantation
Project Type:Retrospective analysis of biobank samples
Project Summary:Organ shortage is the primary limiting factor in liver transplantation and has led to expanded utilization of livers from marginal donors. Assessment of liver allograft quality is currently based on clinical factors such as donor age, cause of death, liver function, routine clinical laboratory values and extent of graft steatosis (fat content). Expanded utilization necessitates a more detailed assessment of liver allograft quality to guide decisions regarding suitability for transplantation. Using a metabolomics approach, we plan to capture molecular snapshots of the physiologic state of the graft and to elucidate biomarkers of allograft quality and graft function post-transplant.
