Vascular smooth muscle cell mechanotransduction: Pathways, phenotypes and emerging technologies

The Journal of Physiology, EarlyView.
Abstract figure legend Vascular smooth muscle cells are exposed to mechanical stimuli from the blood flow and the extracellular matrix. The cells sense the signals from cyclic stretch, shear stress, hydrostatic pressure and matrix stiffness through specialized mechanosensors, such as mechanosensitive ion channels or cell surface receptors including ...

Robust passive and active efflux of cellular cholesterol to a designer functional mimic of high density lipoprotein

Journal of Lipid Research, 2015
The ability of HDL to support macrophage cholesterol efflux is an integral part of its atheroprotective action. Augmenting this ability, especially when HDL cholesterol efflux capacity from macrophages is poor, represents a promising therapeutic strategy.

Oxysterols in Cancer: From Biosynthesis and Pathophysiology to Targeted Therapeutics

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Mechanisms by which oxysterol targeting may enhance immunotherapy efficacy. This figure illustrates potential metabolic interventions that may improve antitumor immunity by modulating oxysterol related pathways. CH25H modulation may reduce 25‐HC accumulation, promote the conversion of cold tumors into hot tumors, and increase T cell infiltration and PD‐

Intestinal cholesterol absorption is substantially reduced in mice deficient in both ABCA1 and ACAT2

Journal of Lipid Research, 2005
The process of cholesterol absorption has yet to be completely defined at the molecular level. Because of its ability to esterify cholesterol for packaging into nascent chylomicrons, ACAT2 plays an important role in cholesterol absorption.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, Volume 16, Issue 8, Page 1563-1592, August 2026.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

PXR induces CYP27A1 and regulates cholesterol metabolism in the intestine

Journal of Lipid Research, 2007
Mitochondrial sterol 27-hydroxylase (CYP27A1) catalyzes oxidative cleavage of the sterol side chain in the bile acid biosynthetic pathway in the liver and 27-hydroxylation of cholesterol in most tissues. Recent studies suggest that 27-hydroxycholesterol (

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, Volume 4, Issue 3, Page 247-260, August 2026.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

A high cholesterol diet accelerates Alzheimer's progression by promoting fibrotic damage in rats

Brain Disorders
The literature documents the ability of oxysterols and TGFβ to cause fibrotic damage in the brain. Our study explores the potential mechanisms of oxysterol interactions with fibrotic mediators in Alzheimer's disease.

Comprehensive Pan‐Cancer Analysis of ABCA1: Insights From Multi‐Omics Data and Exploratory Validation in Esophageal Squamous Cell Carcinoma

Cell Biochemistry and Function, Volume 44, Issue 8, August 2026.
ABSTRACT Cancer remains a major cause of global mortality, necessitating the identification of novel biomarkers to improve prognosis and guide therapy. ABCA1, an ATP‐binding cassette transporter involved in cholesterol efflux, has been implicated in tumorigenesis, yet its pan‐cancer roles and clinical relevance are not fully understood.
