Biotin attenuation of oxidative stress, mitochondrial dysfunction, lipid metabolism alteration and 7β-hydroxycholesterol-induced cell death in 158N murine oligodendrocytes

open access: yes, 2019
Mitochondrial dysfunction and oxidative stress are involved in neurodegenerative diseases associated with an enhancement of lipid peroxidation products such as 7β-hydroxycholesterol (7β-OHC).

Targeting Brain Cholesterol Homeostasis in Alzheimer's Disease: Mechanisms and Therapeutic Perspectives

open access: yesJournal of Neurochemistry, Volume 170, Issue 6, June 2026.
Brain cholesterol homeostasis is tightly regulated and largely independent of peripheral cholesterol. This review proposes a unifying framework in which aging, sex, and related biological stressors, including hypercholesterolemia, neurodegeneration, inflammation, and oxidative stress, converge to disrupt cholesterol homeostasis in the brain ...

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

open access: yes, 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

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

open access: yes, 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 ...

Role for ORPs in 25‐hydroxycholesterol binding to SCAP

open access: yesThe FASEB Journal, 2006
The mechanism by which 25‐hydroxycholesterol influences intracellular lipid homeostasis is not well understood. This oxysterol is known to be ten times more potent inhibitor of SCAP‐SREBP translocation to the Golgi than cholesterol itself, however, the question if it acts directly on SCAP or if it influences its function indirectly remains open.

A Concise Synthesis of 25-Hydroxycholesterol from Hyodesoxycholic Acid

open access: yes, 2018
A simple, efficient and economical method has been developed for the synthesis of 25-hydroxycholesterol in seven steps from hyodesoxycholic acid with an overall yield of 39%.

Effects of 25-hydroxycholesterol and 7-ketocholesterol, inhibitors of sterol synthesis, administered orally to mice.

open access: yes, 1977
When 25-hydroxycholesterol or 7-ketocholesterol was fed to mice with the diet, growth was suppressed and mature mice lost weight. The effect of the 7-ketone upon body weight was effectively counteracted by cholesterol whereas cholestanol and beta ...

Oxysterol-mediated modulation of intestinal inflammation: insights into sex differences and GPR183 signaling

open access: yesCellular and Molecular Life Sciences
Background and aims Oxysterols, oxidized derivatives of cholesterol, play complex roles in inflammatory processes, but their specific functions in inflammatory bowel diseases remain incompletely understood.
