### AI-Powered Drug Discovery for Liver Fibrosis Treatment

Liver fibrosis claims over 1.4 million lives annually, prompting Stanford geneticist Gary Peltz to enlist **Google DeepMind's Co-Scientist** AI to identify repurposable drugs. The tool analyzed existing literature and proposed three candidates, alongside Peltz's own selections, for laboratory testing against human liver cells.

Of the five candidates, Co-Scientist's suggestions outperformed Peltz's manual picks. Two AI-selected drugs blocked fibrosis and promoted liver cell regeneration, while none of Peltz's choices showed benefit. The standout was **vorinostat**, a cancer drug that **blocked 91% of liver damage response**. This gene-activity-targeting approach differs from traditional single-pathway treatments.

Peltz's findings suggest AI-driven drug repurposing could accelerate new anti-fibrotic therapies. By analyzing vast literature pools, Co-Scientist identified overlooked candidates that human researchers might miss, potentially transforming how we approach liver disease treatment.
