Researchers have found that a recently discovered gene regulates HDL (high density lipoproteins) cholesterol, also known as “good” cholesterol. The study, published in the February issue of the Journal of Clinical Investigation, could lead to new therapies for heart disease, said lead author Thomas Quertermous, MD. “This is a significant and unexpected finding, and the gene is going to be a real target for the prevention and treatment of heart disease,” said Quertermous, the William G. Irwin Professor and chief of cardiovascular medicine at Stanford University School of Medicine. “This type of thing doesn’t happen every day.”
