The presence of high blood cholesterol levels, hypercholesterolemia, is a significant contributing factor in the development of coronary heart disease, a condition that is the leading cause of death for both women and men in industrialized countries. Low-density lipoprotein receptor (LDLR) plays a crucial role in the uptake of cholesterol from the blood. Therefore, up-regulation of LDLR is a useful strategy for the treatment of hypercholesterolemia. We have studied the interplay between the AKT signaling pathway and LDLR expression and show that inhibition of AKT activity exerts a potent stimulating effect on LDLR levels by both increasing the transcriptional activity of the LDLR gene and decreasing the LDLR mRNA decay rate.
