p53–CARF interaction and its role in fatty liver and insulin resistance

Impact of inverse relationship between TP53 and CARF on the development of hepatic steatosis and insulin resistance

NIH-funded research Charles R. Drew University of Med & Sci · NIH-11325435

Seeing if changes in two proteins, p53 and CARF, control fat buildup in the liver and insulin resistance in people with obesity or at risk for type 2 diabetes.

What this research studies

We will study how the proteins p53 and CARF work together to cause fat to build up in the liver and to disturb insulin signaling. The team will manipulate CARF levels in liver cells and in high-fat diet mouse models and measure liver fat, insulin pathway signals, and the glucose-making gene PCK1. Methods include gene silencing, adding back CARF, and molecular assays (like CUT&RUN and protein/RNA analyses) to see how CARF controls PCK1 and glucose output. The goal is to link these molecular changes to the development of NAFLD and insulin resistance so new treatments can be designed.

Who could benefit from this research

Good fit: People with obesity, nonalcoholic fatty liver disease (NAFLD), insulin resistance, or early type 2 diabetes would be the most relevant candidates for related future studies or sample donation.

Not a fit: Patients without metabolic liver disease (for example those with genetic liver disorders or advanced cirrhosis from other causes) or those needing immediate clinical treatment are unlikely to benefit directly from this basic laboratory research.

Why it matters

Potential benefit: If successful, this work could identify CARF as a new target to prevent or treat fatty liver and improve insulin resistance in people with obesity or early type 2 diabetes.

How similar studies have performed: Previous laboratory work in cells and high-fat diet mice showed that lowering CARF increases liver fat and that adding CARF can reduce fat deposition, but translating this into human treatments remains novel.
