Mechanisms in Hepatic Lipid Metabolism in Alcohol Use Disorder: From Genomics, Transcriptomics to Metabolomics
National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)
Summary
Patients with hepatic steatosis due to alcohol will be offered liver biopsies when they enter a detoxification program. The first biopsy will occur in the first week of admission and the second in the fourth week when the steatosis has resolved. The hepatic transcriptome will be compared,
Description
Study Description: The liver is central to lipid metabolism, intimately involved with lipid uptake, lipoprotein synthesis and lipid synthesis. Alcohol has known effects on changing lipid composition including increases in HDL and decreases in LDL; nevertheless, the underlying mechanisms of this altered lipoprotein metabolism is not understood. Current spectroscopy data characterize the changes in lipoprotein profiles with alcohol cessation. We aim to study liver lipid metabolism by performing liver biopsies and transcriptome analysis in participants with alcohol use disorder. Objectives: Pr…
