27-Hydroxycholesterol: the first identified endogenous SERM [PDF]

Trends in Endocrinology & Metabolism, 2011
The cholesterol metabolite 27-hydroxycholesterol (27OHC) classically delivers sterols from peripheral tissues to the liver and is a substrate for bile acid synthesis. Recent studies have revealed that 27OHC also binds to and modifies the function of estrogen receptors ERα and ERβ. Experiments in mice lacking the enzyme which synthesizes 27OHC, CYP27A1,

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

Prednisolone suppresses the immunostimulatory effects of 27‑hydroxycholesterol

Experimental and Therapeutic Medicine, 2020
In cholesterol-fed rabbits, site-specific targeting of prednisolone nanoparticles results in significantly reduced neo-intimal inflammation with a decreased infiltration of monocytes/macrophages. To understand the molecular mechanisms underlying this, the current study investigated whether prednisolone affects the immune attributes of 27 ...

The impact of 27-hydroxycholesterol on endometrial cancer proliferation [PDF]

Endocrine Abstracts, 2018
Endometrial cancer (EC) is the most common gynaecological malignancy. Obesity is a major risk factor for EC and is associated with elevated cholesterol. 27-hydroxycholesterol (27HC) is a cholesterol metabolite that functions as an endogenous agonist for Liver X receptor (LXR) and a selective oestrogen receptor modulator (SERM).

DataSheet1_Miconazole Suppresses 27-Hydroxycholesterol-induced Inflammation by Regulating Activation of Monocytic Cells to a Proinflammatory Phenotype.docx

, 2021
Miconazole is effective in treating inflammatory skin conditions and has well-established antifungal effects. To elucidate the underlying mechanisms mediating its additional beneficial effects, we assessed whether miconazole influences the inflammation ...

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 ...

Involvement of 27-Hydroxycholesterol in Mitotane Action on Adrenocortical Carcinoma [PDF]

Cells, 2020
Adrenocortical carcinoma (ACC) is a rare cancer with poor prognosis. Mitotane, the standard treatment for ACC, impairs adrenocortical steroid biosynthesis and cholesterol metabolism. In the H295R cell line, a standard ACC in vitro model, mitotane was previously reported to enhance the production of some oxysterols.

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.

The oncogenic roles of 27‑hydroxycholesterol in glioblastoma

Oncology Letters, 2019
Glioblastoma is the most frequent primary malignant brain tumor in adults. Oxysterols are oxidation products of cholesterol generated by enzymatic reactions. 27-hydroxycholesterol (27-HC), an oxysterol, is an abundant metabolite of cholesterol. 27-HC significantly accelerates mammary cancer growth, proliferation and progression in experimental models ...
