27-Hydroxycholesterol accelerates cellular senescence in human lung resident cells [PDF]

American Journal of Physiology-Lung Cellular and Molecular Physiology, 2016
Cellular senescence is reportedly involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). We previously showed that 27-hydroxycholesterol (27-OHC) is elevated in the airways of COPD patients compared with those in healthy subjects. The aim of this study was to investigate whether lung fibroblasts of COPD patients are senescent and

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

Cancer Nexus, EarlyView.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Cholesterol metabolism in primary biliary cirrhosis during simvastatin and UDCA administration

Journal of Lipid Research, 2001
Little is known about the effects of cholesterol-lowering agents in hypercholesterolemic patients with primary biliary cirrhosis (PBC). The aim of this study was to compare the changes induced by simvastatin and ursodeoxycholic acid (UDCA) on cholesterol

A phase 3, randomized clinical trial of soticlestat as adjunctive therapy for Lennox–Gastaut syndrome

Epilepsia, EarlyView.
Soticlestat as adjunctive therapy for Lennox–Gastaut syndrome. Abstract Objective There remains a need for new treatments for Lennox–Gastaut syndrome (LGS), a developmental and epileptic encephalopathy with a heterogenous patient population that often requires polytherapy. The phase 3, randomized SKYWAY study (NCT04938427) investigated the efficacy and

The Cross-Talk Between the Peripheral and Brain Cholesterol Metabolisms

Current Issues in Molecular Biology
Cholesterol is an essential element for the development and normal function of the central nervous system. While peripheral cholesterol is influenced by liver metabolism and diet, brain cholesterol metabolism takes place in an isolated system due to the ...

On the substrate specificity of human CYP27A1

Journal of Lipid Research, 2003
The mitochondrial sterol 27-hydroxylase (CYP27A1) is required for degradation of the C27-sterol side chain in bile acid biosynthesis. CYP27A1 seems, however, to have roles beyond this, as illustrated by patients with a deficient sterol 27-hydroxylase due

Placenta‐derived extracellular vesicles: Signal messengers shuttling across the maternal‐fetal barrier

Interdisciplinary Medicine, EarlyView.
In normal pregnancy, PEVs help maintain maternal–fetal immune tolerance while enabling controlled immune activation, promote endothelial migration, and support trophoblast invasion and syncytialization, strengthening antimicrobial defense. In pregnancy‐related disorders, dysregulated PEV signaling may drive endothelial dysfunction and hypertension, BBB

Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

VIEW, EarlyView.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

Bile acid synthesis: 7 alpha-hydroxylation of intermediates in the sterol 27-hydroxylase metabolic pathway.

Journal of Lipid Research, 1996
The recognition that the 7 alpha-hydroxylation of 27-hydroxycholesterol is catalyzed by an enzyme that is different from cholesterol 7 alpha-hydroxylase raises the question as to the number of similar enzymes that may be present in liver and subserve ...
