How the liver enzyme CYP1B1 contributes to liver scarring

Official title: Cellular and Metabolic Basis of the Role of CYP1B1 in Liver Fibrosis

Funded at University of Pittsburgh at Pittsburgh · NIH-11293462 · Data updated 2026-11-12

This research tests whether blocking the liver enzyme CYP1B1 can stop the scar-forming cells that drive liver fibrosis in people with chronic liver injury.

Who could benefit from this research

Could help

Ideal candidates would be adults with chronic liver disease or liver fibrosis who can provide clinical information and possibly blood or liver tissue samples for research.

Less likely to help

People without liver disease or those with very advanced, decompensated cirrhosis may not directly benefit from this early laboratory-focused research.

What this research studies

Researchers are studying liver tissue and cells from humans and mice to see how CYP1B1 affects activation of hepatic stellate cells, the cells that lay down scar tissue. They measure CYP1B1 levels, track cell metabolism and autophagy, and use genetic removal or drugs to turn CYP1B1 off. The team links those molecular changes to signs of fibrosis in lab models and in samples from people with fibrotic livers. Findings could point to new drug targets to slow or stop worsening liver scarring.

Why it matters

Potential benefit: If successful, this work could identify a new target (CYP1B1) for drugs that reduce liver scarring and slow progression of liver fibrosis.

How similar studies have gone: Previous preclinical work shows that blocking autophagy can limit activation of scar-forming liver cells, but the role of CYP1B1 in fibrosis is a new finding being actively explored.
