Why Liver Damage Persists Even After Stopping Alcohol

Topic: Health

Scientists at the University of Illinois and Duke University discovered why livers don't heal after alcohol damage. They found that liver cells get stuck in a state where they can't function or regenerate, even when drinking stops.

The liver is an amazing organ because it can repair itself after injury. It can even grow back if some of it is removed. But this ability breaks down in people with alcohol-related liver disease. This condition causes around 3 million deaths each year worldwide.

Researchers at the University of Illinois and Duke University wanted to know why livers don't heal after alcohol damage. They studied liver cells from healthy people and those with alcohol-related liver disease. They found that liver cells get stuck in a state where they can't function or regenerate, even when drinking stops.

This is because inflammation caused by alcohol disrupts RNA splicing. RNA splicing is an important process that helps turn genetic instructions into working proteins. When this process is disrupted, liver cells can't complete the regeneration process. As a result, more and more liver cells become trapped in this state, leading to liver failure.

The researchers hope their findings will lead to new ways to diagnose and treat severe alcohol-related liver disease.

Why It Matters

This research matters because it could help us develop new treatments for people with liver damage caused by drinking. In India, where alcohol consumption is a growing concern, this could be especially important.
