Study TitleMetabolomics Approach to Allograft Assessment in Liver Transplantation
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.
