Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

open access: yesAdvanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Targeting the GPX4–FUNDC1 Interaction with Magnesium Lithospermate B Attenuates Sepsis‐Associated Lung Injury

open access: yesAdvanced Science, EarlyView.
The diagram depicts the endothelial‐protective mechanism of magnesium lithospermate B (MLB) in sepsis‐associated lung injury. MLB binds GPX4 at Gly79, disrupts its interaction with FUNDC1, prevents mitophagy‐mediated GPX4 degradation, restores mitophagic flux, reduces ROS, and limits ferroptosis.

Chaperone‐Mediated Autophagic Degradation of USP9X in Macrophages Exacerbates Postmyocardial Infarction Inflammation and Cardiac Dysfunction

open access: yesAdvanced Science, EarlyView.
This study demonstrates that inflammatory stimuli induce the acetylation‐triggered, chaperone‐mediated autophagic degradation of ubiquitin‐specific peptidase 9 X‐linked (USP9X) in macrophages. USP9X acts as a macrophage “inflammation switch” after myocardial infarction (MI). USP9X loss destabilizes tumor necrosis factor receptor‐associated factor (TRAF)

PAF Triggered Pyroptotic NETosis Aggravates Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Platelet activating factor (PAF) secreted by cardiomyocytes during MI/R, drives NETs formation and subsequent NETosis. PAF/NETosis signaling activation is an initiative and causal factor in driving MI/R injury. This study identifies dapagliflozin as a potent NETosis inhibitor, and demonstrates that manipulating PAF‐NETosis signal by dapagliflozin or ...

Mild therapeutic hypothermia upregulates the O-GlcNAcylation level of COX10 to alleviate mitochondrial damage induced by myocardial ischemia–reperfusion injury

open access: yesJournal of Translational Medicine
Objective Mild therapeutic hypothermia (MTH) is an important method for perioperative prevention and treatment of myocardial ischemia–reperfusion injury (MIRI). Modifying mitochondrial proteins after protein translation to regulate mitochondrial function

Detection of Myocardial Ischemia-Reperfusion Injury Using a Fluorescent Near-Infrared Zinc(II)-Dipicolylamine Probe and Tc Glucarate

open access: yesMolecular Imaging, 2012
A fluorescent zinc 2,2′-dipicolylamine coordination complex PSVue®794 (probe 1) is known to selectively bind to phosphatidylserine exposed on the surface of apoptotic and necrotic cells.

Decoding the Cardiac Immune Microenvironment and Fibroblast Crosstalk in Radiotherapy Combined with Immunotherapy‐Induced Cardiac Fibrosis Based on Single‐Cell Transcriptomic Analysis

open access: yesAdvanced Science, EarlyView.
This study highlights that radioimmunotherapy drives crosstalk between fibroblasts and immune cells (especially macrophages) in the cardiac microenvironment, with IL‐6 as the key mediator, and tocilizumab alleviates cardiac fibrosis by targeting this interplay.

Reperfusion in acute myocardial infarction [PDF]

open access: yesDrug and Therapeutics Bulletin, 2005
Each year, around 240,000 people in England and Wales have an acute myocardial infarction.1 Of these, around half die within a month, many before reaching medical help. The likelihood of early and longer-term morbidity (e.g. heart failure, arrhythmias) and death is related to the extent of myocardial damage.

Gut Microbiota‐Non‐Coding RNA Axis in Immune Modulation and Disease: From Mechanisms to Clinical Translation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Immune homeostasis is indispensable for preserving organismal integrity, orchestrated through complex molecular networks encompassing immune cell dynamics, microbial cues, and epigenetic regulation. Among these, the gut microbiota‐non‐coding RNA (ncRNA) axis has recently garnered substantial attention as a multifaceted modulator of host ...
