(PHILADELPHIA) – Researchers at the University of Pennsylvania School of Medicine have discovered that a group of liver enzymes called proprotein convertases (PCs) may be the key to raising levels of good cholesterol (HDL-C). The pathway by which these proteins are able to achieve an increase in HDL cholesterol involves another enzyme that normally degrades HDL-C, and was also discovered at Penn. The newly recognized relationship between these enzymes and cholesterol represents another target for ultimately controlling good cholesterol. The study appears in the current issue of Cell Metabolism.
