General description
27-hydroxycholesterol induces glutathione depletion, apoptosis, reactive oxygen species (ROS) generation and inflammation.
Biochem/physiol Actions
27-hydroxycholesterol is a peripherally derived oxysterol that that is produced by the enzyme CYP27A1. There has beeen increasing interest in the oxysterols, especially in the brain. Impairment of brain cholesterol metabolism has been associated with several neurodegenerative diseases. 27-hydroxycholesterol crosses the blood brain barrier and have been associated with Alzheimer′s disease. It is an activator of LXRα and LXRβ in vitro with EC50 values of 85 and 71 nM and an inhibitor of cholesterol synthesis. 27-hydroxycholesterol has also been shown to bind to estrogen receptor-α (ERα) and Erβ, acting as an endogenous selective estrogen receptor modulator (SERM). In murine models of breast cancer 27-hydroxycholesterol significantly increased tumor growth and metastasis.

Oxysterols are products of enzymatic and/or chemical cholesterol oxidation. While some of the former possess broad antiviral activities, the latter mostly originate from the deterioration of the nutritional value of foodstuff after exposure to heat, light, radiation and oxygen, raising

Cholesterol 25-hydroxylase (CH25H) is an interferon-stimulated gene that converts cholesterol to the oxysterol 25-hydroxycholesterol (25HC). Circulating 25HC modulates essential immunological processes including antiviral immunity, inflammasome activation and antibody class switching; and dysregulation of CH25H may contribute to chronic inflammatory disease
