Ischemic heart disease remains a leading cause of human mortality worldwide. One form of ischemic heart disease is ischemia-reperfusion injury caused by the reintroduction of blood supply to ischemic cardiac muscle. The short and long-term damage that occurs due to ischemia-reperfusion injury is partly due to the proteolysis of diverse protein substrates inside and outside of cardiomyocytes. Ischemia-reperfusion activates several diverse intracellular proteases, including, but not limited to, matrix metalloproteinases, calpains, cathepsins, and caspases. This review will focus on the biological roles, intracellular localization, proteolytic targets, and inhibitors of these proteases in cardiomyocytes following ischemia-reperfusion injury. Recognition of the intracellular function of each of these proteases includes defining their activation, proteolytic targets, and their inhibitors during myocardial ischemia-reperfusion injury. This review is a step toward a better understanding of protease activation and involvement in ischemic heart disease and developing new therapeutic strategies for its treatment.

Genistein-3'-sodium sulfonate suppresses NLRP3-mediated cell pyroptosis after cerebral ischemia.

Metab Brain Dis

Key Laboratory of Prevention and treatment of cardiovascular and cerebrovascular diseases of Ministry of Education, Gannan Medical University, Ganzhou, 341000, China.

Cerebral ischemia-induced pyroptosis contributes to the dissemination of neuroinflammation, and Nod-like receptor protein-3 (NLRP3) inflammasome plays a key role in this process. Previous studies have indicated that Genistein-3'-sodiumsulfonate (GSS) can inhibit neuroinflammation caused by cerebral ischemia, exert cerebroprotective effects, but its specific mechanism has not been comprehensively understood. The aim of this study was to explore the effect of GSS on ischemic stroke-induced cell pyroptosis.

Unlabelled: Periodontitis is closely related to renal health, but the specific influence of (), a key pathogen in periodontitis, on the development of acute kidney injury (AKI) in mice has not been fully elucidated. In our study, AKI was induced in mice through ischemia-reperfusion injury while administering oral infection with . Comprehensive analyses were conducted, including 16S rRNA sequencing, liquid chromatography-mass spectrometry (LC-MS) metabolomics, and transcriptome sequencing.

Introduction: The mechanism of remimazolam, a benzodiazepine that activates γ-aminobutyric acid a (GABAa) receptors, in cerebral ischemia/reperfusion (I/R) injury is not well understood. Therefore, we explored whether remimazolam activates protein kinase B (AKT)/glycogen synthase kinase-3β (GSK-3β)/nuclear factor erythroid 2-related factor 2 (NRF2) to attenuate brain I/R injury in transcerebral I/R-injured rats and transoxygenic glucose deprivation/reperfusion (OGD/R)-injured SY5Y cells.

Material And Methods: Remimazolam was added at the beginning of cell and rat reperfusion, and the PI3K/AKT inhibitor LY294002 was added to inhibit the AKT/GSK-3β/NRF2 pathway 24 h before cellular OGD/R treatment and 30 min before rat brain I/R treatment.

The Keap1 (Kelch-like ECH-Associating Protein 1)-Nrf2 (Nuclear Factor Erythroid 2-Related Factor 2)-ARE (Antioxidant Response Element) signaling pathway plays a crucial role in the oxidative stress response and has been linked to the development and progression of various diseases. Its influence on cerebral ischemia/reperfusion (I/R) injury has garnered significant attention. In our study, we investigated the effect of compound 2, a non-covalent inhibitor of the Keap1-Nrf2 interaction, which was previously discovered by our research group.

[Mechanism of ginsenoside Rg_1 in regulating autophagy through miR-155/Notch1/Hes1 pathway to attenuate hypoxia/reoxygenation injury in HL-1 cells].

This article explored the specific mechanism by which ginsenoside Rg_1 regulates cellular autophagy to attenuate hypoxia/reoxygenation(H/R) injury in HL-1 cardiomyocytes through the microRNA155(miR-155)/neurogenic gene Notch homologous protein 1(Notch1)/hairy and enhancer of split 1(Hes1) pathway. An HL-1 cell model with H/R injury was constructed, and ginsenoside Rg_1 and/or Notch1 inhibitor DAPT and miR-155 mimics were used to treat cells. Cell counting kit(CCK)-8 was used to detect the relative viability of HL-1 cells with H/R injury.
