27-Hydroxycholesterol in cancer development and drug resistance [PDF]

Journal of Enzyme Inhibition and Medicinal Chemistry
27-Hydroxycholesterol (27HC), a cholesterol metabolite, functions both as a selective oestrogen receptor (ER) modulator and a ligand for liver X receptors (LXRs).

Paroxetine suppresses 27-hydroxycholesterol-induced responses in THP-1 human monocytic cells by regulating the AKT/mTORC1 pathway [PDF]

Scientific Reports
Paroxetine (PRX) is widely prescribed for treating psychiatric disorders. Emerging evidence suggests that PRX can act as an immunosuppressive agent, yet the molecular mechanisms underlying its effects are not fully understood. This study has investigated

The Plasma Distribution of Non-cholesterol Sterol Precursors and Products of Cholesterol Synthesis and Phytosterols Depend on HDL Concentration

Frontiers in Nutrition, 2022
Non-cholesterol sterols are transported in plasma lipoproteins and are consequently important in cholesterol metabolism. We investigated the distribution of non-cholesterol sterol precursors of cholesterol synthesis (NCSPCS), oxysterols, and phytosterols

Oxysterols Protect Epithelial Cells Against Pore-Forming Toxins

Frontiers in Immunology, 2022
Many species of bacteria produce toxins such as cholesterol-dependent cytolysins that form pores in cell membranes. Membrane pores facilitate infection by releasing nutrients, delivering virulence factors, and causing lytic cell damage - cytolysis ...

Are side-chain oxidized oxysterols regulators also in vivo?

Journal of Lipid Research, 2009
Oxsterols are oxygenated metabolites of cholesterol that are short-lived intermediates or end products in cholesterol excretion pathways. They are present in very low concentrations in mammalian systems, always accompanied by a high excess of cholesterol.

Side chain oxidized oxysterols in cerebrospinal fluid and the integrity of blood-brain and blood-cerebrospinal fluid barriers

Journal of Lipid Research, 2003
The side chain oxidized oxysterol 24S-hydroxycholesterol (24-OH-chol) is formed almost exclusively in the brain, and there is a continuous passage of this oxysterol through the circulation to the liver.

Brain-Specific Oxysterols and Risk of Schizophrenia in Clinical High-Risk Subjects and Patients With Schizophrenia

Frontiers in Psychiatry, 2021
Accumulating evidence from clinical, genetic, and epidemiologic studies suggest that schizophrenia might be a neuronal development disorder. While oxysterols are important factors in neurodevelopment, it is unknown whether oxysterols might be involved in

Changes in the levels of cerebral and extracerebral sterols in the brain of patients with Alzheimer's disease

Journal of Lipid Research, 2004
24S-hydroxycholesterol is a side-chain oxidized oxysterol formed in the brain that is continuously crossing the blood-brain barrier to reach the circulation. There may be an opposite flux of 27-hydroxycholesterol, which is formed to a lower extent in the

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.
