Abstract
Background: Different strains of rats have been used to study alcoholic liver disease (ALD) while the reason for selecting a particular rat strain was not apparent.
Purpose: The aim of our study was to compare outbred (Wistar) and inbred (Fischer) strains to evaluate pathological, biochemical changes, and gene expression differences associated with ethanol-induced early hepatic steatosis.
Study design: Male Wistar and Fischer-344 rats were pair-fed for 6 weeks with or without 5% ethanol in Lieber-DeCarli liquid diet. Livers were analyzed for histological and lipid-related differences.
Results: Hepatic midzonal steatosis was mainly found in Wistar rats while Fischer rats showed mostly pericentral steatosis. Increased hepatic steatosis in ethanol-fed Wistar rats is supported by increases in lipids with related genes and transcription factors involved in fatty acid and triglyceride synthesis.
Conclusion: Our data showed that Fischer rats are relatively less prone to ethanol-mediated steatosis with pericentral lipid deposition pattern in the liver which is similar to humans and show no trace level of lipid accumulation in pair-fed controls as observed in Wistar (outbred) strain. Therefore, Fischer rats are better suited for lipid studies in an early development of ALD.
期刊介绍:
The Journal of Drug and Alcohol Research (JDAR) is a scholarly open access, peer-reviewed, and fully refereed journal dedicated to publishing sound papers on advances in the field of drug, opiate, nicotine and alcohol abuse, both basic and clinical. The journal will consider papers from all sub-disciplines and aspects of drug abuse, dependence and addiction research. Manuscripts will be published online as soon as they are accepted, which will reduce the time of publication. Because there are no space limitations or favored topics, all papers, within the scope of the journal, judged to be sound by the reviewers, will be published.
