TRPA1 channel contributes to myocardial ischemia-reperfusion injury [PDF]

American Journal of Physiology-Heart and Circulatory Physiology, 2019
Myocardial ischemia-reperfusion (I/R) results in the generation of free radicals, accumulation of lipid peroxidation-derived unsaturated aldehydes, variable angina (pain), and infarction. The transient receptor potential ankyrin 1 (TRPA1) mediates pain signaling and is activated by unsaturated aldehydes, including acrolein and 4-hydroxynonenal.

XIAP Stabilizes DDRGK1 to Promote ER‐Phagy and Protects Against Noise‐Induced Hearing Loss

Advanced Science, EarlyView.
Mechanism of GAS‐mediated protection against noise‐induced hearing loss (NIHL). Noise exposure activates the ATF4/eIF2α axis, downregulating XIAP and promoting DDRGK1 degradation, thereby inhibiting ER‐phagy and leading to hair cell (HC) death. GAS treatment rescues XIAP and DDRGK1 expression, reactivating ER‐phagy to mitigate HC loss, synaptic damage,

Myocardial necrosis markers in myocardial ischemia reperfusion (MI/R) injury: a review

Medicine Science, 2017
Myocardial ischemia/reperfusion injury is one of the main causes of morbidity and mortality in the world. This injury is experienced by patients suffering from cardiovascular diseases such as coronary heart diseases and subsequently undergoing ...

Enhanced Na\u3csup\u3e+\u3c/sup\u3e/H\u3csup\u3e+\u3c/sup\u3e Exchange During Ischemia and Reperfusion Impairs Mitochondrial Bioenergetics and Myocardial Function [PDF]

, 2008
Inhibition of Na+/H+ exchange (NHE) during ischemia reduces cardiac injury due to reduced reverse mode Na+/Ca2+ exchange. We hypothesized that activating NHE-1 at buffer pH 8 during ischemia increases mitochondrial oxidation, Ca2+ overload, and reactive ...

Targeting Microglial CD49a Inhibits Neuroinflammation and Demonstrates Therapeutic Potential for Parkinson's Disease

Advanced Science, EarlyView.
This study shows that integrin receptor CD49a (Itga1 gene) is significantly upregulated in hyperactivated microglia and microglia‐specific knockdown of Itga1 rescues neuroinflammation and neurodegeneration in a chronic Parkinson's disease (PD) model by targeting PGAM5‐mediated mitochondrial dysfunction and NLRP3 activation. Targeted inhibition of CD49a

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced 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.

Signal transducer and activator of transcription-1 localizes to the mitochondria and modulates mitophagy [PDF]

, 2013
The signal transducer and activator of transcription (STAT) proteins are latent transcription factors that have been shown to be involved in cell proliferation, development, apoptosis, and autophagy. STAT proteins undergo activation by phosphorylation at

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

Advanced 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.

Forefront of Na+/Ca2+ Exchanger Studies: Role of Na+/Ca2+ Exchanger – Lessons From Knockout Mice

Journal of Pharmacological Sciences, 2004
We used Na+/Ca2+ exchanger (NCX) knockout mice to evaluate the effects of NCX in cardiac function and the infarct size after ischemia/reperfusion injury.

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

Advanced 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)
