Regulatory Effects of Ammonium Chloride in an In Vitro Model of Hepatic Encephalopathy: Mechanisms Involving ACTA2‐Mediated Cytoskeletal Remodeling

iLABMED, EarlyView.
Hyperammonemic stress suppresses ACTA2 expression and induces F‐actin cytoskeletal remodeling in astrocytes. The resulting inhibition of FAK/c‐Src signaling contributes to apoptosis, G2/M arrest, AQP4‐mediated swelling and junction‐associated proteins dysregulation, revealing a central role for ACTA2‐dependent cytoskeletal dysfunction in hepatic ...

Diurnal testosterone oscillations gate drug delivery via phase separation of ZO-1 at the blood-testis barrier in mice

Communications Biology
The blood-testis barrier is essential for sperm development but also blocks the delivery of non-hormonal male contraceptives and other germ-cell-targeting therapies.

Inhibition of MicroRNA‐155 Supports Endothelial Tight Junction Integrity Following Oxygen‐Glucose Deprivation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Brain microvascular endothelial cells form a highly selective blood brain barrier regulated by the endothelial tight junctions. Cerebral ischemia selectively targets tight junction protein complexes, which leads to significant damage to ...

Regulation of Pacemaker Current in the Sinoatrial Node by Zonula Occludens-1

ABSTRACT BACKGROUND In addition to lethal ventricular arrhythmias, arrhythmogenic cardiomyopathy (ACM) is associated with conduction abnormalities, bradycardias, and reduced expression of the scaffolding junctional protein zonula occludens-1 (ZO-1).

N6‐Methyladenosine in Inflammatory Bowel Disease: An Emerging Regulator of Pathogenesis and a Novel Therapeutic Frontier

iMetaMed, EarlyView.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine associated with an imbalance in intestinal homeostasis. m6A‐modifying enzymes, consisting of m6A writers, erasers and readers, plays a pivotal role in the pathogenesis and progression of IBD by affecting four intestinal barriers, including the intestinal mechanical ...

Immune Checkpoint Inhibitors Induce Intestinal Epithelial Injury and a Senescence‐Like Phenotype

iNew Medicine, EarlyView.
ICI treatment promotes the infiltration of activated immune cells into the intestinal mucosa. This inflammatory microenvironment is associated with significant epithelial injury, characterized by the disruption of the epithelial barrier, the depletion of specialized secretory cell lineages, and the induction of a premature senescence phenotype ...

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Short‐Term 6PPD‐Q Exposure alters Tight‐Junction‐Related Gene Expression Without Acute Lethality in Japanese Medaka Oryzias latipes

Journal of Applied Toxicology, EarlyView.
ABSTRACT 6PPD‐quinone (6PPD‐Q), a transformation product of the tire antioxidant 6PPD, causes acute mortality in several salmonid species, but its toxicity varies markedly among fish species. Disruption of vascular‐barrier integrity and inflammatory signaling has been proposed as a key mechanism of 6PPD‐Q toxicity.

HIV-1 transgene expression in rats causes oxidant stress and alveolar epithelial barrier dysfunction

AIDS Research and Therapy, 2009
Background HIV-infected individuals are at increased risk for acute and chronic airway disease even though there is no evidence that the virus can infect the lung epithelium.
