Scientists reversed liver aging with young gut bacteria in stunning study

Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own preserved youthful microbiome showed less inflammation, reduced DNA damage, and no signs of liver cancer. Researchers also found that the treatment suppressed a cancer-linked gene called MDM2, making older mice biologically resemble younger ones.
