Molecular Mechanisms Involved Involved In The Interaction Effects Of Hcv And Ethanol On Liver Cirrhosis, Ryan Fassnacht

Theses and Dissertations

The leading causes of liver disease are Hepatitis C virus infection and chronic alcohol abuse. Alcohol accelerates liver disease in HCV but the mechanisms are poorly understood. The identification of molecular gene expression profiles on human liver tissue was performed using microarrays. Samples were obtained from alcoholic-cirrhotic, HCV-cirrhotic, HCV/alcohol-cirrhotic and control non-cirrhotic liver tissue. Probe set expression summaries were calculated using RMA. Probe set level linear models were fit where probe set expression was modeled by HCV status, alcohol status, and the interaction between HCV and Alcohol. HCV cirrhosis was associated with up-regulation of genes related to viral and immune …
