Understanding how a protein called Rap1a affects cholesterol levels in the liver

Hepatic Rap1a in cholesterol homeostasis

NIH-funded research Columbia University Health Sciences · NIH-11093371

This research explores how a specific protein in the liver, Rap1a, helps control cholesterol levels, especially for people with high cholesterol and heart disease risk.

What this research studies

We are looking into how a protein called Rap1a in your liver might help manage cholesterol, which is important because high cholesterol can lead to heart disease. Our work suggests that activating Rap1a could lower levels of a harmful type of cholesterol called LDL-C. We also found that common cholesterol-lowering medicines, called statins, can sometimes reduce Rap1a's activity, which might make them less effective. By understanding this process better, we hope to find new ways to improve how we treat high cholesterol.

Who could benefit from this research

Good fit: This foundational research is relevant to patients with high cholesterol, atherosclerotic cardiovascular disease, or adult-onset diabetes mellitus who are at risk for heart complications.

Not a fit: Patients without high cholesterol or a risk of atherosclerotic cardiovascular disease would not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this research could lead to new medications or strategies that more effectively lower harmful cholesterol levels and reduce the risk of heart disease.

How similar studies have performed: This proposal is based on new findings from the research team's laboratory, suggesting a novel approach to regulating cholesterol.
