Baat‐Deficient Mice Recapitulate Elevated 7α‐Hydroxy‐3‐Oxo‐4‐Cholestenoic Acid Observed in a Japanese Patient With BAAT Deficiency

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 5, September 2026.
ABSTRACTBile acid Coenzyme A: amino acid N‐acyltransferase (BAAT) catalyzes the conjugation of bile acids with taurine or glycine, a process essential for bile acid solubility and intestinal lipid absorption. Mutations in BAAT cause an inborn error of bile acid metabolism, typically characterized by reduced conjugated bile acids and fat‐soluble vitamin

Serum cholestenoic acid as a potential marker of pulmonary cholesterol homeostasis

open access: yesJournal of Lipid Research, 2004
The conversion of cholesterol into the more polar metabolites 27-hydroxycholesterol (27-OH) and cholestenoic acid by the cytochrome P450 sterol 27-hydroxylase is a cholesterol-removal mechanism used by almost all cells.

4β-Hydroxycholesterol Signals From the Liver to Regulate Peripheral Cholesterol Transporters

open access: yesFrontiers in Pharmacology, 2020
Activation of pregnane X receptor (PXR) elevates circulating 4β-hydroxycholesterol (4βHC), an agonist of liver X receptor (LXR). PXR may also regulate 25-hydroxycholesterol and 27-hydroxycholesterol.

Metabolism in Tumor: Mechanisms and Therapeutic Perspectives

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Tumor metabolic reprogramming converges on three hubs—the SREBP1/2–FASN–SCD1 lipogenic axis, the HIF‐1α–GLUT1–LDHA glycolytic axis, and the LDLR–SCARB1–LXR cholesterol system—which integrate transcriptional, epigenetic (histone lactylation, m6A), and microenvironmental inputs to generate metabolic plasticity, immune evasion, and therapy resistance ...

Metabolism of 4 beta -hydroxycholesterol in humans

open access: yes, 2002
One of the major oxysterols in the human circulation is 4 beta-hydroxycholesterol formed from cholesterol by the drug-metabolizing enzyme cytochrome P450 3A4.

Increased maternal and fetal cholesterol efflux capacity and placental CYP27A1 expression in preeclampsia[S]

open access: yesJournal of Lipid Research, 2017
Preeclampsia is a pregnancy-specific condition that leads to increased cardiovascular risk in later life. A decrease in cholesterol efflux capacity is linked to CVD.

Differential effects of 24-hydroxycholesterol and 27-hydroxycholesterol on β-amyloid precursor protein levels and processing in human neuroblastoma SH-SY5Y cells [PDF]

open access: yes, 2009
Background Activation of the liver × receptors (LXRs) by exogenous ligands stimulates the degradation of β-amyloid 1–42 (Aβ42), a peptide that plays a central role in the pathogenesis of Alzheimer's disease (AD).

Sterol 27-hydroxylase: expression in human arterial endothelium

open access: yesJournal of Lipid Research, 1997
Human endothelium obtained from both the aorta and the pulmonary artery has been evaluated for the presence of the messenger RNA coding for the expression of sterol 27-hydroxylase.

24-Hydroxycholesterol is a substrate for hepatic cholesterol 7α-hydroxylase (CYP7A)

open access: yesJournal of Lipid Research, 2000
(24S)-Hydroxycholesterol is formed from cholesterol in the brain and is important for cholesterol homeostasis in this organ. Elimination of (24S)-hydroxycholesterol has been suggested to occur in the liver but little is known about the metabolism of this

Effects of 26-aminocholesterol, 27-hydroxycholesterol, and 25-hydroxycholesterol on proliferation and cholesterol homeostasis in arterial myocytes

open access: yes, 1995
The major relation existing between cell growth and cholesterol homeostasis prompted us to investigate the effect of 26-aminocholesterol (26-NH2), 27-hydroxycholesterol (27-OH), and 25-hydroxycholesterol (25-OH) on these cellular events.
