Hormetic Effects of 7-Ketocholesterol in Preventing Ferroptosis in Hepatocytes. [PDF]

Oxid Med Cell Longev
Background and Aims Ferroptosis, a form of cell death marked by iron dysregulation and lipid peroxidation, has been implicated in liver and neurodegenerative diseases. 7‐ketocholesterol (7KC), a cholesterol oxidation product, induces oxidative stress and inflammation at high concentrations.

The terminal enzymes of cholesterol synthesis, DHCR24 and DHCR7, interact physically and functionally[S]

Journal of Lipid Research, 2015
Cholesterol is essential to human health, and its levels are tightly regulated by a balance of synthesis, uptake, and efflux. Cholesterol synthesis requires the actions of more than twenty enzymes to reach the final product, through two alternate ...

7-Dehydrocholesterol down-regulates cholesterol biosynthesis in cultured Smith-Lemli-Opitz syndrome skin fibroblasts

Journal of Lipid Research, 1998
The Smith-Lemli-Opitz syndrome (SLOS) is a common birth defect–mental retardation syndrome caused by a defect in the enzyme that reduces 7-dehydrocholesterol to cholesterol.

Vulnerability of DHCR7+/− mutation carriers to aripiprazole and trazodone exposure

Journal of Lipid Research, 2017
Smith-Lemli-Opitz syndrome is a recessive disorder caused by mutations in 7-dehydrocholesterol reductase (DHCR)7 with a heterozygous (HET) carrier frequency of 1–3%.

Desmosterol and 7-dehydrocholesterol concentrations in post mortem brains of depressed people: The role of trazodone

Translational Psychiatry, 2022
Major depressive disorder (MDD) is a common, disabling, and heterogeneous condition that responds unpredictably to current treatments. We previously showed an association between depressive symptoms and plasma concentrations of two cholesterol precursors,

Variability in genes regulating vitamin D metabolism is associated with vitamin D levels in type 2 diabetes [PDF]

, 2018
Mortality rate is increased in type 2 diabetes (T2D). Low vitamin D levels are associated with increased mortality risk in T2D. In the general population, genetic variants affecting vitamin D metabolism (DHCR7 rs12785878, CYP2R1 rs10741657, GC rs4588 ...

Changes in serum sterols of rats treated with 7-dehydrocholesterol-delta 7-reductase inhibitors: comparison to levels in humans with Smith-Lemli-Opitz syndrome.

Journal of Lipid Research, 1996
The impaired conversion of 7-dehydrocholesterol to cholesterol, as a result of a permanent inhibition of the activity of 7-dehydrocholesterol-delta 7-reductase, has been reported in the Smith-Lemli-Opitz (SLO) syndrome (1, 2).

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

, 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
