Cholesterol oxidized products in foods: potential health hazards and the role of antioxidants in prevention

Grasas y Aceites, 2004
Cholesterol is a molecule with a double bond in its structure, and therefore it is susceptible to oxidation leading to the formation of oxysterols. These oxidation products are found in many commonly consumed foods and are formed during their manufacture

Human breast milk lipoproteins: A preliminary biochemical characterization

Experimental Physiology, EarlyView.
Abstract Human breast milk (BM) is an essential fluid for infant development, with a dynamic composition adapted to the infant's needs. It contains bioactive lipids like cholesterol, typically transported by lactosomes, extracellular vesicles, and milk fat globules. However, classic cholesterol‐carrying lipoproteins have not been described in BM.

A quantitative LC-MS/MS method for analysis of mitochondrial -specific oxysterol metabolism

Redox Biology, 2020
Oxysterols are critical regulators of inflammation and cholesterol metabolism in cells. They are oxidation products of cholesterol and may be differentially metabolised in subcellular compartments and in biological fluids.

Decoding Undesirable Inflammatory Responses of Nucleic Acid‐Delivering Lipid Nanoparticles

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Lipid nanoparticles (LNPs) enable efficient nucleic acid delivery, but their immunogenicity is a double‐edged sword. This review explores LNP‐driven innate and adaptive immunity, covering lipid components, endosomal escape, and nucleic acid sensing.

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

Advanced Science, Volume 13, Issue 33, 15 June 2026.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

Involvement of 27-Hydroxycholesterol in Mitotane Action on Adrenocortical Carcinoma

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.

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

American Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1179-1191, June 2026.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

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.

Silymarin and Its Isolated Flavanonol Lignans Are Liver X Receptor Antagonists

Archiv 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 ...
