Potential new strategy for raising 'good' cholesterol levels: MicroRNA and host gene play key role

Researchers have identified tiny segments of RNA that may play an important role in the body's regulation of cholesterol and lipids. Their study found that the miR-33 familyof microRNAs suppress a protein known to be important for generation of HDL -- the "good cholesterol" that transports lipids to the liver for disposal -- and for the removal of cholesterol from peripheral tissues, including cells that form atherosclerotic plaques.
