University of Nebraska Medical Center


Our faculty work on clinical trials related to inflammatory bowel diseases, eosinophilic esophagitis, gastroparesis, alcoholic and non-alcoholic hepatitis, NASH, and other gastrointestinal and hepatology illnesses.

The Alcohol Liver Study Unit is comprised of a large team of basic scientists conducting ongoing research investigating:

  • How alcohol consumption affects protein degradation in the liver and the brain.
  • Ethanol metabolism on cellular replication.
  • Ethanol as it relates to altered protein trafficking and the pathogenesis of alcoholic liver injury.
  • The role of iron as a secondary risk factor in liver diseases, including oxidative stress induced by agents such as alcohol or hepatitis C viral proteins is one of the primary underlying mechanisms of iron overload.

Understanding these processes may help researchers develop novel diagnostic markers and therapeutic strategies.
