Silymarin and Its Isolated Flavanonol Lignans Are Liver X Receptor Antagonists

open access: yesArchiv der Pharmazie, Volume 359, Issue 6, June 2026.
Despite its long tradition in the treatment of liver‐related ailments, the precise mode of action of the milk thistle fruit extract remains vague. Here we identified liver X receptor as a molecular target of silymarin, a mixture of bioactive compounds from milk thistle extract, and its major flavanonol lignan components, which account for their anti ...

Assays of plasma dehydrocholesteryl esters and oxysterols from Smith-Lemli-Opitz syndrome patients[S]

open access: yesJournal of Lipid Research, 2013
Smith-Lemli-Opitz syndrome (SLOS) is caused by mutations in the gene encoding 3β-hydroxysterol-Δ7-reductase and as a result of this defect, 7-dehydrocholesterol (7-DHC) and 8-dehydrocholesterol (8-DHC) accumulate in the fluids and tissues of patients ...

Bioinspired Aerobic Oxidation to Functionalize the CD Ring of the Steroid Framework: Synthesis and Stereochemical Assignments of Gargalol C and Related Oxysterols

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
Bioinspired aerobic oxidation of the CD ring part of 5,6‐α‐epoxysterols was achieved by two means. The study not only led to the first syntheses and configurational (re)assignments of naturally occurring bioactive C14‐ or C15‐hydroxysterols but also gives valuable insights into the biosynthetic pathways of advanced oxysterols. A series of NMR and X‐ray

OXYSTEROLS AND PHYTOSTEROLS IN HUMAN PATHOPHYSIOLOGY: Adipocytes in tumour microenvironment promote chemoresistance in triple-negative breast cancer through oxysterols

open access: yesRedox Experimental Medicine
Objective: Triple-negative breast cancer (TNBC) patients with excess adipose tissue experience poorer disease-free survival than those with a healthy body mass index. Adipocytes store and release cholesterol, which can be hydroxylated to form oxysterols.

Unveiling Candidate Markers for Drug Resistance or Synthetic Lethality in Cervical Cancer: Integrative Analysis of Genetic and Pharmacoprofiling

open access: yesCancer Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Introduction Systemic cervical cancer management continues to be challenging. Numerous chemotherapies have been approved, but predicting response is difficult due to the lack of biomarkers. Here, we analyze the genetic and protein profiles of 20 cervical cancer cell lines (CCCLs) and explore their correlation with drug response patterns to ...

Rapid hepatic metabolism of 7-ketocholesterol in vivo: implications for dietary oxysterols

open access: yesJournal of Lipid Research, 1999
7-Ketocholesterol is a major dietary oxysterol and the predominant non-enzymically formed oxysterol in human atherosclerotic plaque. We tested the hypothesis that 7-ketocholesterol is preferentially retained by tissues relative to cholesterol in vivo. To

CYP46A1‐Targeted Treatment Alleviates Long‐Term White Matter Injury Following Traumatic Brain Injury by Promoting Cholesterol Metabolic Clearance and Remyelination

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
Our findings demonstrate that CYP46A1 plays a critical role in regulating cholesterol homeostasis in microglia and that the targeting of CYP46A1 may offer a viable therapeutic approach for traumatic brain injury (TBI). The CYP46A1 activator Efavirenz reduces white matter damage by increasing the levels of the cholesterol metabolite 24OHC, thereby ...

Oxysterols contribute to immune cell recruitment in SLE skin lesions

open access: yesArthritis Research & Therapy
Background Abnormal oxysterol metabolism has been observed in the peripheral blood of SLE patients, but its role in systemic lupus erythematosus (SLE) skin lesions remains unclear.

Physiology, pathology and therapeutic potential of microglial triggering receptor expressed on myeloid cells 2 signalling: A narrative update

open access: yesClinical and Translational Discovery, Volume 6, Issue 3, June 2026.
TREM2hi microglia and macrophages exert distinct roles in neurological diseases. Enhancing TREM2 signalling supports pathological protein or debris clearance and mitigates inflammation in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, demyelination disorders and stroke, whereas blocking TREM2 may alleviate tauopathy and ...

Oxysterols in intestinal immunity and inflammation [PDF]

open access: yesJournal of Internal Medicine, 2018
AbstractCholesterol is an essential molecule for life. It is a component of the cell membrane, and it is a precursor molecule for bile acids, vitamin D and steroid hormones. Cholesterol is actively metabolized, but the impact of endogenous cholesterol metabolites on immune function, especially in the intestine, is poorly understood.
