Diatoms synthesize sterols by inclusion of animal and fungal genes in the plant pathway [PDF]

open access: yes, 2020
Diatoms are ubiquitous microalgae that have developed remarkable metabolic plasticity and gene diversification. Here we report the first elucidation of the complete biosynthesis of sterols in the lineage.

Non-skeletal activities of vitamin d: From physiology to brain pathology [PDF]

open access: yes, 2019
Vitamin D is a secosteroid hormone regulating the expression of almost 900 genes, and it is involved in the regulation of calcium and phosphate metabolism, immune response, and brain development.

7-Dehydrocholesterol is an endogenous suppressor of ferroptosis [PDF]

open access: yes, 2021
Abstract Ferroptosis is a form of cell death that has received considerable attention not only as a means to eradicate defined tumour entities but also because it provides unforeseen insights into the metabolic adaptation exploited by tumours to counteract phospholipid oxidation.

Oxidized derivatives of 7-dehydrocholesterol induce growth retardation in cultured rat embryos: a model for antenatal growth retardation in the Smith-Lemli-Opitz syndrome

open access: yesJournal of Lipid Research, 1999
7-Dehydrocholesterol accumulates in fetuses affected by the Smith-Lemli-Opitz syndrome as a result of a deficit in the ultimate step of cholesterol synthesis catalyzed by Δ7 reductase.

Identification of 8-dehydrocholesterol (cholesta-5,8-dien-3 beta-ol) in patients with Smith-Lemli-Opitz syndrome.

open access: yesJournal of Lipid Research, 1995
Cholesta-5,8-dien-3 beta-ol (8-dehydrocholesterol) and cholesta-5,7-dien-3 beta-ol (7-dehydrocholesterol) were isolated from the fecal neutral sterol fraction from homozygotes with Smith-Lemli-Opitz syndrome.

Defective conversion of 7-dehydrocholesterol to cholesterol in cultured skin fibroblasts from Smith-Lemli-Opitz syndrome homozygotes

open access: yesJournal of Lipid Research, 1995
The Smith-Lemli-Opitz syndrome is a common birth defect syndrome characterized biochemically by low plasma cholesterol levels and high concentrations of the cholesterol precursor 7-dehydrocholesterol.

Effect of a new inhibitor of cholesterol biosynthesis (AY 9944) on serum and tissue sterols in the rat

open access: yesJournal of Lipid Research, 1966
AY 9944 is a novel inhibitor of cholesterol biosynthesis which appears to act on the Δ7-reductase enzyme, interfering with the conversion of 7-dehydrocholesterol to cholesterol.

Vitamin D in plants: a review of occurrence, analysis, and biosynthesis. [PDF]

open access: yes, 2013
The major function of vitamin D in vertebrates is maintenance of calcium homeostasis, but vitamin D insufficiency has also been linked to an increased risk of hypertension, autoimmune diseases, diabetes and cancer. Therefore, there is a growing awareness

Oxysterols in the circulation of patients with the Smith-Lemli-Opitz syndrome: abnormal levels of 24S- and 27-hydroxycholesterol

open access: yesJournal of Lipid Research, 2001
Infants with the cholesterol synthesis defect Smith-Lemli-Opitz syndrome (SLO) have reduced activity of the enzyme 7-dehydrocholesterol-7-reductase and accumulate 7-dehydrocholesterol, with the highest concentration in the brain.

Individual and simultaneous treatment with antipsychotic aripiprazole and antidepressant trazodone inhibit sterol biosynthesis in the adult brain

open access: yesJournal of Lipid Research, 2022
Polypharmacy, or the simultaneous use of multiple drugs to treat a single patient, is a common practice in psychiatry. Unfortunately, data on the health effects of commonly used combinations of medications are very limited.
