Blocking RGC-32 to prevent harmful artery wall changes

Targeting response gene to complement 32 to alleviate vascular remodeling

NIH-funded research University of Missouri-Columbia · NIH-11251971

Researchers will try blocking a protein called RGC-32 to reduce harmful artery wall changes in people with conditions like pulmonary arterial hypertension and artery restenosis.

What this research studies

This project focuses on a protein called RGC-32 that helps blood vessel lining cells change into scar-forming cells (a process called endothelial-to-mesenchymal transition, or EndoMT). Scientists will work with human pulmonary artery endothelial cells in the lab, examine samples from patients with pulmonary arterial hypertension, and use genetically modified mice to model disease. They will reduce or increase RGC-32 in cells and animals and measure endothelial and mesenchymal markers, blood vessel structure, and heart/pulmonary pressures. The goal is to connect findings from cells and mice to what is seen in patient tissues to guide future therapies.

Who could benefit from this research

Good fit: Ideal candidates would be people with pulmonary arterial hypertension or patients who have artery restenosis or other forms of vascular remodeling and who might later join trials targeting RGC-32.

Not a fit: Patients without vascular remodeling or those with unrelated medical conditions are unlikely to receive direct benefit from this primarily preclinical project.

Why it matters

Potential benefit: If successful, this work could identify a new target (RGC-32) for treatments that prevent or reduce artery wall scarring and complications such as pulmonary hypertension or restenosis.

How similar studies have performed: Prior laboratory and animal studies have connected RGC-32 and EndoMT to vascular disease, but directly targeting RGC-32 as a therapy remains largely untested in humans.
