Alcohol-related liver disease (ALD) is the leading cause of death from long-term heavy drinking in the United States, and there are no effective therapies. One of the first things alcohol damages in liver cells is the mitochondrion, the cell's energy-producing compartment.

What they work on

  1. Establish whether chronic alcohol consumption disrupts 24-hour rhythms in liver mitochondrial energy production, including the activity of cytochrome c oxidase, the rate-limiting enzyme of respiration, in alcohol-fed mice.
  2. Define how the liver-cell clock factors BMAL1 and E4BP4 contribute to alcohol-induced mitochondrial dysfunction and liver injury, using mice with these genes altered specifically in liver cells.
  3. Test whether reinstating liver clock activity during chronic alcohol use prevents mitochondrial dysfunction and the development of alcohol-related liver injury.

More about the research

Exactly how this damage happens, and how much it contributes to disease, is unclear. The project links this damage to the body's internal 24-hour clock, the molecular circadian clock that helps organs respond to stresses.

Why it matters

Patients with alcohol-related liver disease currently have no effective drug treatments. By showing whether a disrupted liver clock drives mitochondrial energy failure, this work may provide the preclinical basis for new therapies. These could include treatments aimed at mitochondria or timed to the body's daily rhythms, for ALD and other serious liver diseases.
