<p>Researchers have discovered that the smooth muscle cells that line the arteries of people with atherosclerosis can change into new cell types and develop traits similar to cancer that worsen the disease. Atherosclerosis is characterized by a narrowing of arterial walls and can increase risk of coronary artery disease, stroke, peripheral artery disease, or kidney disorders. The findings, supported by the National Institutes of Health (NIH), could pave the way for the use of anti-cancer drugs to counteract the tumor-like mechanisms driving the buildup of plaque in the arteries, the major cause of cardiovascular disease.</p>
