Sumario:Cholesterol is a vital lipid for cellular functions. It is necessary for membrane biogenesis, cell proliferation, and differentiation. In addition to maintaining cell integrity and permeability, increasing evidence indicates a strict link between cholesterol homeostasis, inflammation, and hematological tumors. This makes cholesterol homeostasis an optimal therapeutic target for hematopoietic malignancies. Manipulating cholesterol homeostasis by either interfering with its synthesis or activating the reverse cholesterol transport via the engagement of liver X receptors affects the integrity of tumor cells both in vitro and in vivo. Cholesterol homeostasis has also been manipulated to restore antitumor immune responses in preclinical models. These observations have prompted clinical trials involving acute myeloid leukemia to test the combination of chemotherapy with drugs interfering with cholesterol synthesis (ie, statins). We review the role of cholesterol homeostasis in hematopoietic malignancies as well as in cells of the tumor microenvironment and discuss the potential use of lipid modulators for therapeutic purposes.
