Food Restriction Counteracts Dexamethasone-Induced Downregulation of Genes Involved in Cholesterol Homeostasis in Rat Brain during Aging

open access: yesBrain Sciences, 2022
Glucocorticoids are the most potent anti-inflammatory agents known. Limited in vivo data are available to characterize the mechanism underlying their cognitive side effects and transient occurrence of steroid psychosis.

Effect of Amyloid Beta on Cholesterol Metabolism-Correlated microRNAs in Primary Cultured Astrocytes of C57BL/6J Mice: A Focus on CYP46A1 and APOE Genes [PDF]

open access: yesCell Journal
Objective: The accumulation of amyloid plaques and disturbance of cholesterol homeostasis are implicated in thepathophysiology of Alzheimer’s disease. Apolipoprotein E (ApoE) and cholesterol 24-hydroxylase (CYP46A1) are keyproteins involved in the efflux

Transcriptional regulation of the human CYP46A1 brain‐specific expression by Sp transcription factors [PDF]

open access: yesJournal of Neurochemistry, 2008
AbstractBrain defective cholesterol homeostasis has been associated with neurologic diseases, such as Alzheimer’s and Huntington’s disease. The elimination of cholesterol from the brain involves its conversion into 24(S)‐hydroxycholesterol by CYP46A1, and the efflux of this oxysterol across the blood–brain barrier.

Sex-dependent effects of CYP46A1 overexpression on cognitive function during aging [PDF]

open access: yes, 2021
ABSTRACT Cholesterol turnover and CYP46A1 regulation are reported to be crucial for memory functions. An increasing body of evidence shows that CYP46A1 activation is able to reduce Alzheimer’s Disease (AD) pathological processes.

Antifungal Azoles: Structural Insights into Undesired Tight Binding to Cholesterol-Metabolizing CYP46A1 [PDF]

open access: yesMolecular Pharmacology, 2013
Although there are currently three generations of antifungal azoles on the market, even the third-generation agents show undesirable interactions with human cytochrome P450 (P450) enzymes. CYP46A1 is a cholesterol-metabolizing P450 in the brain that tightly binds a number of structurally distinct azoles. Previously, we determined the crystal structures

Phytosterols reverse antiretroviral-induced hearing loss, with potential implications for cochlear aging.

open access: yesPLoS Biology, 2023
Cholesterol contributes to neuronal membrane integrity, supports membrane protein clustering and function, and facilitates proper signal transduction. Extensive evidence has shown that cholesterol imbalances in the central nervous system occur in aging ...

Altered Cholesterol Homeostasis in Huntington’s Disease

open access: yesFrontiers in Aging Neuroscience, 2022
Huntington’s disease (HD) is an autosomal dominant genetic disorder caused by an expansion of the CAG repeat in the first exon of Huntingtin’s gene.

Excitotoxicity increases the release of 24S-hydroxycholesterol via CYP46A1 activation [PDF]

open access: yesMolecular Neurodegeneration, 2013
Background Excitotoxicity, a common hallmark of different neurological disorders including Alzheimer’s disease (AD), is the consequence of exacerbated neuronal stimulation and leads to a high influx of calcium trough membrane glutamate receptors [1]. On the other hand, high levels of the cholesterol metabolite 24S-hydroxycholesterol (24-HC) have been ...

PPAR-γ and CYP46A1 genes polymorphism is associated with Primary Open Angle Glaucoma (POAG) in hypertensive North Indians

open access: yesEgyptian Journal of Medical Human Genetics, 2017
Background: Involvement of genetic factors like gene polymorphisms was found to contribute significantly to development and progression of Primary Open Angle Glaucoma (POAG) in the last few decades.

The CH24H metabolite, 24HC, blocks viral entry by disrupting intracellular cholesterol homeostasis

open access: yesRedox Biology, 2023
Cholesterol-24-hydroxylase (CH24H or Cyp46a1) is a reticulum-associated membrane protein that plays an irreplaceable role in cholesterol metabolism in the brain and has been well-studied in several neuro-associated diseases in recent years.
