Abstract
This review examines the relationship between cholesterol and bone resorption. It seeks to elucidate the dependence of bone turnover on cholesterol metabolism by highlighting the common inhibitory effect of both statins and nitrogen-containing bisphosphonates on cholesterol biosynthesis and bone resorption as well as on bone density. Moreover, this paper also discusses the epidemiologic studies of the effects of nitrogen-containing bisphosphonates on all-cause and cardiovascular mortality using the latest publications to reinforce the relationship between bone resorption and cardiovascular disease. This review will also discuss the role of lipoproteins in supplying cholesterol to both osteoclasts and osteoblasts and the effects of doing so on both of these bone cells and their precursors. As inflammation is a major factor in both bone resorption and cardiovascular calcification, this article will also discuss the role of cholesterol in triggering inflammatory responses. Finally, this paper will raise questions unanswered to date that bear on the relationship between lipid metabolism, bone resorption, and cardiovascular disease.
