Delayed diagnosis of 3β‐HSD7 deficiency in adolescence: Two case reports and review of the literature

JPGN Reports, EarlyView.
ABSTRACT Congenital bile acid synthesis defects (BASD), the most common of which is 3β‐hydroxy‐Δ5‐C27‐steroid dehydrogenase oxidoreductase (3β‐HSD7) deficiency, are a rare cause of fat‐soluble vitamin malabsorption. We describe a 14‐year‐old girl who presented at 14 months with a left distal femur fracture and failure to thrive.

Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

VIEW, EarlyView.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

Amplification of the gene for SCAP, coupled with Insig-1 deficiency, confers sterol resistance in mutant Chinese hamster ovary cells

Journal of Lipid Research, 2007
The endoplasmic reticulum membrane proteins Insig-1 and Insig-2 limit cholesterol synthesis, in part through their sterol-dependent binding to sterol-regulatory element binding protein (SREBP) cleavage-activating protein (SCAP).

Binding of 25-hydroxycholesterol and cholesterol to different cytoplasmic proteins [PDF]

Proceedings of the National Academy of Sciences, 1977
Studies were carried out to determine whether or not oxygenated derivatives of cholesterol (e.g., 25-hydroxycholesterol) that specifically suppress the activity of 3-hydroxy-3-methylglutaryl-CoA reductase [mevalonate:NADP + oxidoreductase (CoA-acylating), EC 1.1.1.34], bind to a soluble component of the cytoplasm ...

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

The cholesterol metabolite 27-hydroxycholesterol inhibits SARS-CoV-2 and is markedly decreased in COVID-19 patients

Redox Biology, 2020
There is an urgent need to identify antivirals against the coronavirus SARS-CoV-2 in the current COVID-19 pandemic and to contain future similar emergencies early on.

Pharmacological inhibition of hydroxysteroid 11‐beta dehydrogenase type 1 (11‐βHSD1) after myocardial infarction preserves cardiac function in a translational mini‐pig model

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Plasma glucocorticoids increase acutely after MI, thereafter tissue levels are amplified selectively within cells expressing 11‐ßhydroxysteroid dehydrogenase type 1 (11‐ßHSD1) that regenerates active glucocorticoids from circulating metabolites.

Side chain hydroxylation of cholesterol, campesterol and β-sitosterol in rat liver mitochondria

Journal of Lipid Research, 1976
The extent of the side chain hydroxylation of cholesterol, campesterol (24 α-methylcholesterol), and β-sitosterol (24 α-ethylcholesterol) in rat liver mitochondria has been compared.

High cholesterol absorption efficiency interferes with bile acid metabolism and cholesterol elimination from the body

Journal of Internal Medicine, EarlyView.
Abstract Background Elevated low‐density lipoprotein (LDL) cholesterol causes atherosclerotic cardiovascular diseases. Variables of whole‐body cholesterol metabolism, for example, high cholesterol absorption efficiency, might also be atherogenic, whereas the role of bile acids is controversial.
