Returning to the University of Texas Health Science Center in Dallas in 1972 (now called UT Southwestern Medical Center) Goldstein and his close colleague Brown researched cholesterol metabolism and discovered that human cells have low-density lipoprotein (LDL) receptors that extract cholesterol from the bloodstream. The lack of sufficient LDL receptors is the cause of

Goldstein and Brown's findings led to better understanding the mechanism of action of

New federal cholesterol guidelines are expected to triple the number of Americans taking statin drugs to lower their cholesterol, reducing the risk of heart disease and stroke for countless people. Subsequently the team led by Drs. Brown and Goldstein elucidated the role of lipid modification of proteins (protein

that proteolytically releases the SREBPs from membranes, thus allowing their migration to the nucleus where they activate all the genes involved in the synthesis of cholesterol and fatty acids. The machinery for generating active SREBPs is tightly regulated by a negative feedback mechanism, which explains how cells maintain the necessary levels of fats and cholesterol in the face of varying environmental circumstances.
