Livers can be damaged by stress and aging, leading to disease, severe scarring and failure.
Researchers found a way to potentially reverse liver damage in mice.
"Aging promotes a type of cell death in hepatocytes called ferroptosis, which is dependent on iron," - Anna Mae Diehl, senior author.
Human fatty livers also showed signs of increased ferroptosis, amplifyng stress in other tissues.
A drug called Ferrostatin-1 blocked this cell death pathway in mice.
Livers of the treated mice looked biologically like young, healthy livers.
This suggests reversal of age-related liver damage might be possible.
