Summary

Story summary

A study shows that alcohol intake hinders liver regeneration by keeping cells in a non-functional state, persisting even after drinking stops.
This issue arises from inflammation disrupting RNA splicing, as detailed in *Nature Communications*.
Alcohol-related liver disease accounts for about 3 million deaths each year.
Liver cells revert to a progenitor state but fail to mature due to faulty RNA editing.
Deficiency of the protein ESRP2, essential for RNA splicing, contributes to liver damage.
