Targeting Nupr1‐Mediated p53 Mitochondrial Sequestration Alleviates Aortic Dissection by Restoring the Gadd45b‐Dependent Survival Program

Advanced Science, EarlyView.
This study identifies Nupr1 as a crucial stress‐responsive orchestrator driving AD. Under severe stress, Nupr1 massively accumulates within mitochondria to sequester p53, triggering apoptosis and concurrently repressing the Gadd45b‐mediated survival program.

Pulmonary vascular remodeling occurs in severe equine asthma.

, 2016
Severe equine asthma (heaves) is a chronic genetic-environmental condition characterized by airway neutrophilic inflammation leading to airway obstruction, lung tissue remodeling and hypoxemia (Bullone, 2015). Hypoxemia triggers pulmonary vasoconstriction, resulting in higher vascular resistance and development of pulmonary hypertension (PH).

RBMS1 Contributes to Early Arteriovenous Fistula Neointimal Remodeling Through Modulation of VSMC Phenotypic Responses

Advanced Science, EarlyView.
Postoperative arteriovenous fistulas exhibit increased RBMS1 in vascular smooth muscle cells (VSMCs). In experimental AVFs, RBMS1 overexpression aggravates, whereas deletion attenuates, neointimal hyperplasia. RBMS1 binds MPZL1 mRNA and promotes exon 5 skipping to generate MPZL1‐Δ5, which interacts with G3BP1 to activate AKT, driving VSMC proliferation,

Mechanical Distraction Engages a Neuro‐Immune Program to Drive Regenerative Soft‐Tissue Healing in Ilizarov Bone Transport

Advanced Science, EarlyView.
Ilizarov bone transport accelerates healing of soft‐tissue wounds through unclear mechanisms. In a rat model, sustained mechanical distraction elicits calcitonin gene‐related peptide (CGRP)‐dominant sensory reinnervation, creating a niche that shifts immune cells from inflammatory to repair‐promoting states and speeds re‐epithelialization.

Notoginsenoside R1 Improved Hypoxic Pulmonary Hypertension by Inhibiting Glycolysis-Mediated Pulmonary Arterial Vascular Remodeling

Canadian Respiratory Journal
Hypoxic pulmonary hypertension (HPH) lacks effective treatments. The research is designed to examine the effectiveness of Notoginsenoside R1 (NGR1) in addressing HPH and to explore its molecular mechanisms.

Macrophage GLUD1 is Essential for Redox Balance and Immune Homeostasis in Cardiac Injury

Advanced Science, EarlyView.
Excessive free radical production and dysregulated immune responses are key contributors to myocardial ischemia‐reperfusion (IR) injury. Macrophage GLUD1 activity safeguards against HIF‐1α accumulation and maladaptive responses to IR‐induced ROS production.

Ischemic Postconditioning Protects Aged Myocardium Against Ischemia/Reperfusion Injury by Regulating Mitochondrial Dynamics via piR‐4913

Advanced Science, EarlyView.
A tiny RNA tips the scales of cardiac injury in aging. piR‐4913 recruits OGT to Drp1 and drives its O‐GlcNAcylation at Thr604, promoting excessive mitochondrial fission that aggravates ischemia‐reperfusion injury. Ischemic postconditioning silences this pathway to restore mitochondrial balance and protect the aged myocardium, revealing piR‐4913 as a ...
