Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

open access: yesAdvanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Molecular Landscapes of Tumor Dormancy in Gynecologic Malignancies: From Survival Mechanisms to Precision Interception

open access: yesAdvanced Science, EarlyView.
This Review outlines the biological framework of entry, maintenance, and awakening in dormant minimal residual disease across gynecologic cancers. By mapping critical biological dependencies—from metabolic plasticity to microenvironment interactions—it evaluates novel interception concepts and presents a translational framework combining single‐cell ...

Effects of misoprostrol on pentylenetetrazol-induced seizures in mice Efeitos de misoprostrol sobre convulsões induzidas por pentilenotetrazol em camundongos

open access: yesArquivos de Neuro-Psiquiatria, 1997
The effects of prostaglandin E - analogue misoprostol on the susceptibility to pentilenetetrazol(PTZ) - induced seizures were examined in mice. Misoprostol (200-800 mg/kg), given subcutaneously 45 min before the subconvulsive dose of PTZ (30 mg/kg, i.p ...

Role of prostaglandins in regulating gastric motility

open access: yes, 1984
Muscles of the stomach possess the ability to synthesize several prostaglandins. These compounds function as local regulatory agents by influencing the motor performance of the muscle cells.

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

open access: yesAdvanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Preliminary Study on the Restoration of the Phospholipid Profile in Serum from Patients with COVID-19 by Treatment with Vitamin E

open access: yesCurrent Issues in Molecular Biology
SARS-CoV-2 is an obligatory intracellular pathogen that requires a lipid bilayer membrane for its transport to build its nucleocapsid envelope and fuse with the host cell.

Structural Control of Stromal‐Immune Coupling by COL24A1 Underlies Pregnancy Maintenance

open access: yesAdvanced Science, EarlyView.
COL24A1 emerges as a collagen‐associated regulator of maternal‐fetal interface homeostasis. Its deficiency promotes a maladaptive TIMP1‐high stromal state, impaired ECM turnover, collagen accumulation, and stromal–immune dysregulation, contributing to pregnancy loss.

Comparative Effects of Platelet-Rich Plasma, Prostaglandin E1, and Dexpanthenol on Wound Healing in an Experimental Pharyngocutaneous Fistula Model

open access: yesB-ENT
Objective: Pharyngocutaneous fistula (PCF) remains a major complication after laryngopharyngeal surgery. Experimental data investigating potential therapeutic agents for improving PCF healing are limited. This study aimed to establish a reproducible rat

Nuciferine Suppresses Inflammatory Hepatocarcinogenesis by Targeting cPLA2‐Dependent Arachidonic Acid Metabolism

open access: yesAdvanced Science, EarlyView.
Nuciferine directly binds the C2 domain of cPLA2, impairing its Ca2+‐dependent membrane translocation and activation. By suppressing arachidonic acid release and downstream pro‐inflammatory eicosanoid production, nuciferine attenuates NF‐κB signaling and inflammatory hepatocarcinogenesis, revealing cPLA2 as a direct molecular target underlying its ...
