Oxysterols are oxygenated derivatives of cholesterol formed in the human body or
ingested in the diet. By modulating the activity of many proteins [e.g., liver X
receptors (LXRs), oxysterol-binding proteins (OSBPs), some ATP-binding cassette
(ABC) transporters], oxysterols can affect many cellular functions and influence
various physiological processes (e.g., cholesterol metabolism, membrane fluidity
regulation, intracellular signaling pathways). Therefore, the role of oxysterols
is also important in pathological conditions (e.g., atherosclerosis, diabetes
mellitus type 2, neurodegenerative disorders). Finally, current evidence suggests
that oxysterols play a role in malignancies such as breast, prostate, colon, and
bile duct cancer. This review summarizes the physiological importance of
oxysterols in the human body with a special emphasis on their roles in various
tumors.
