Metabolite Identification
Common Name25-Hydroxycholesterol
Description25-Hydroxycholesterol is steroid derivative that suppresses the cleavage of sterol regulatory element binding proteins (SREBPs). It also induces apoptosis through down-regulation of Bcl-2 expression and activation of caspases. 25-Hydroxycholesterol also enhances Interleukin-1 beta (IL-1beta-induced) IL-8 production.(PMID: 17086498 ). 25-hydroxycholesterol is endogenously produced from cholesterol at early time intervals after cholesterol ingestion. It inhibits HMG-CoA reductase and so it also plays a significant role in the in vivo regulation of cholesterol biosynthesis after an acute dietary cholesterol challenge.

2. Oxysterol-binding protein 1
General function:
Involved in steroid metabolic process
Specific function:
Binds cholesterol and a range of oxysterols. Cholesterol binding promotes the formation of a complex with PP2A and a tyrosine phosphatase which dephosphorylate ERK1/2, whereas 25- hydroxycholesterol causes its disassembly. Regulates cholesterol efflux by decreasing ABCA1 stability

3. Cholesterol 25-hydroxylase
General function:
Involved in iron ion binding
Specific function:
Catalyzes the formation of 25-hydroxycholesterol from cholesterol, leading to repress cholesterol biosynthetic enzymes. May play an important role in regulating lipid metabolism by synthesizing a corepressor that blocks sterol regulatory element binding protein (SREBP) processing. In testis, production of 25-hydroxycholesterol by macrophages may play a role in Leydig cell differentiation.
