Background: Myocardial ischemia/reperfusion (I/R) injury is a common pathophysiological change after myocardial reperfusion therapy. Recent research confirmed that long non-coding RNA (IncRNAs) played an important role in many cardiovascular diseases. This study was carried out to explore the role of lncRNA XR008038 in the I/R progression.
Methods: GSE103731 database was downloaded from NCBI Gene Expression Omnibus to analyze the differently expressed lncRNAs. Cell viability was determined by CCK-8 assay. Cell apoptosis was detected by flow cytometry and TUNEL staining. Northern blot and qRT-PCR was carried out to detect the XR008038 levels. The mitochondrial membrane potential was assessed by JC-1 staining. Western blot was conducted to measure the expression of apoptosis related proteins. RNA pull down and RIP assay was carried out to explore the relationship between XR008038 and galectin-3.
Results: The results showed that XR008038 was up-regulated in the H/R treated H9c2 cells and the myocardial tissues of the I/R rats. XR008038 silencing promoted the cell growth and mitochondrial membrane potential, inhibited the cell apoptosis of the H/R treated H9c2 cells. Additionally, the MDA content was decreased and SOD activity was enhanced in the H/R treated H9c2 cells and the myocardial tissues of the I/R rats after XR008038 knockdown. XR008038 interacted with galectin-3 and further regulated the mRNA stability of galectin-3. Galectin-3 overexpression neutralized the role of si-XR008038 in the H/R treated H9c2 cells.
Conclusion: In conclusion, XR008038 promoted the oxidative damage in I/R progression through regulating the galectin-3 levels.

Myocardial ischemia/reperfusion injury (MIRI) worsens ischemic damage, with ferroptosis as a key mediator of this iron-dependent cell death. Lactylation, a novel epigenetic modification, remains poorly understood in MIRI-associated ferroptosis. This study aimed to elucidate the mechanistic link between lactylation and ferroptosis in MIRI.

Background: Myocardial ischemia/reperfusion (I/R) injury is a common cause of death. FXYD domain-containing ion transport regulator-5 (Fxyd5) is a type I membrane protein that plays a significant role in mediating cellular functions. However, the expression and function of Fxyd5 in myocardial I/R injury remain unclear.

Background: In ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches), an invasive strategy demonstrated better health status outcomes than a conservative strategy in patients with chronic coronary disease (CCD). Some previous studies have shown greater health status benefits with coronary artery bypass grafting (CABG) than percutaneous coronary intervention (PCI). Whether the health status benefits of invasive management in ISCHEMIA were driven primarily by participants treated with CABG is unknown.

Background: Brain metastases (BM) are common in non-small cell lung cancer (NSCLC). Although guidelines recommend baseline BM screening in asymptomatic patients, its benefit remains unproven. Routine imaging burdens healthcare systems and patients.

Natural flavonoid astragalin (AST) has many pharmacological effects and has been reported to improve renal injury in diabetic kidney disease. This study aimed to investigate the role of AST in renal ischemia/reperfusion injury (RIRI) and elucidate related mechanisms. The RIRI mouse models were pre-treated with AST (25, 50, or 75 mg/kg) 24 h before ischemia/reperfusion surgery.
