4β-hydroxycholesterol signals from the liver to regulate peripheral cholesterol transporters

, 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.

25-Hydroxycholesterol-induced elevation in 45Ca uptake: correlation with depressed DNA synthesis.

, 1984
The mechanism whereby 25-hydroxycholesterol, an inhibitor of the synthesis of cholesterol, depresses DNA synthesis in cycling P815 mastocytoma cells was investigated. The uptake of 45Ca into P815 cells treated with 1 microgram/ml 25-hydroxycholesterol

Oxysterols, age-related-diseases and nutritherapy: Focus on 7-ketocholesterol and 7β-hydroxycholesterol [PDF]

Age-related diseases are often associated with a disruption of RedOx balance that can lead to lipid peroxidation with the formation of oxysterols, especially those oxidized on carbon-7: 7-ketocholesterol (also known as 7-oxo-cholesterol) and 7β ...

25-Hydroxycholesterol-induced elevations in 45Ca uptake: permeability changes in P815 cells.

, 1985
Certain oxysterols are capable of suppressing the activity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase. We have previously demonstrated that treatment of P815 cells with 1 microgram 25-hydroxycholesterol/ml culture results in a rapid ...

Regulation of low density lipoprotein metabolism by 26-hydroxycholesterol in human fibroblasts

, 1987
Oxygenated derivatives of cholesterol are believed to play a role in cellular cholesterol homeostasis through the feed-back control of its biosynthesis.

Plasma 24S-hydroxycholesterol : a peripheral indicator of neuronal degeneration and potential state marker for Alzheimer's disease

, 2000
The conversion of brain cholesterol into 24S-hydroxycholesterol and its subsequent release into the periphery is probably an important step for the maintenance of brain cholesterol homeostasis.

Primary open-angle glaucoma: association with cholesterol 24S-hydroxylase (CYP46A1) gene polymorphism and plasma 24-hydroxycholesterol levels

, 2009
Purpose. Genetics has made significant contributions to the study of glaucoma over the past few decades. Cholesterol-24S-hydroxylase (CYP46A1) is a cholesterol-metabolizing enzyme that is especially expressed in retinal ganglion cells.

Inhibition of herpes simplex-1 virus replication by 25-hydroxycholesterol and 27-hydroxycholesterol

, 2017
Oxysterols are known pleiotropic molecules whose antiviral action has been recently discovered. Here reported is the activity of a panel of oxysterols against HSV-1 with the identification of a new mechanism of action.

Voltammetric detection of 27-hydroxycholesterol on boron-doped diamond electrode

The aim of this bachelor thesis was to study the voltammetric behavior of 27-hydroxycholesterol using boron-doped diamond electrode. The influence of several factors on the current response of 27-hydroxycholesterol was investigated: the effect of the ...
