Cholesterol, statins and cancer

Abstract

1. The link between cholesterol and cardiovascular disease is well-established. Emerging evidence is now forging a tantalizing link between cholesterol and cancer. 2. Results from a number of case-control studies have indicated that the commonly prescribed cholesterol-lowering drugs, the statins, may reduce the risk of certain cancers, although this area certainly remains controversial. 3. Herein, the recent literature examining statins and cancer is reviewed briefly and the relationship between a key cholesterol homeostatic pathway and signalling pathways that are involved in carcinogenesis is discussed. In particular, how the sterol-regulatory element binding protein, Akt and Hedgehog pathways may converge in cancer is reviewed.
