How everyday environmental chemicals may worsen artery plaque

Role of PXR in EDC-induced cardiovascular disease

NIH-funded research University of California Riverside · NIH-11309139

This work explores whether exposure to common endocrine-disrupting chemicals makes artery plaque and cholesterol worse in adults at risk for atherosclerotic cardiovascular disease.

What this research studies

From your point of view, the team is trying to understand how certain everyday chemicals (called endocrine-disrupting chemicals, or EDCs) interact with a protein in the body called PXR that helps control fat and cholesterol. They run lab experiments and use mouse models to see how EDCs change lipid levels and speed up plaque buildup in arteries. The researchers compare those lab findings with available human data and may use human samples or data to link the lab results to people. Ultimately they want to map the gene–chemical interactions that could explain why some people get worse atherosclerosis after chemical exposure.

Who could benefit from this research

Good fit: Adults age 21 and older with atherosclerotic cardiovascular disease or who are at high risk for ASCVD are the most relevant group for this research.

Not a fit: Children, people with non-atherosclerotic heart conditions, or those with no meaningful exposure to the studied environmental chemicals are unlikely to see direct benefits from this project.

Why it matters

Potential benefit: If successful, this work could point to new ways to reduce chemical-driven cholesterol problems or plaque formation and identify people most at risk from environmental exposures.

How similar studies have performed: Previous animal studies, including work from this team, have shown that some EDCs acting through PXR increase atherosclerosis, but confirmation in humans remains limited.
