Authors analyzed articles that opioids may aggravate ischemic and reperfusion damages of the heart but the opioid receptor antagonists may prevent these damages. Authors concluded the it is existed opioid receptor pool an activation of its decreases cardiac tolerance to an impact of ischemia-reperfusion.

ITFG2 is an intracellular protein known to modulate the immune response of T-cells. Our previous investigation revealed that ITFG2 specifically targets ATP5b to regulate ATP energy metabolism and maintain mitochondrial function, thereby protecting the heart from ischemic injury. However, the role of ITFG2 in ischemic ventricular arrhythmias and its underlying mechanisms have not been previously reported.

Cerebral ischemia-reperfusion injury (CIRI), which stays unresolved in the clinic, occurs after recanalization of blood vessels serving brain tissues in acute ischemic stroke patients and can result in massive brain cell death, and cell ferroptosis contributes greatly to this process. Our research firstly found that TNFSF9 expression harbored diagnostic value on CIRI patients and intended to further investigate its regulatory mechanism in CIRI, which might facilitate its diagnostic and therapeutic application in the clinic. The level of TNSF9 mRNA was augmented in the plasma of CIR patients, and its silence impeded ferroptosis, apoptosis, and release of inflammatory mediators of BMECs with OGD/R treatment.

Acute myocardial infarction (AMI) is associated with well-established metabolic risk factors, especially hyperlipidemia and obesity. Myocardial ischemia-reperfusion injury (mIRI) significantly offsets the therapeutic efficacy of revascularization. Previous studies indicated that disrupted lipid homeostasis can lead to lipid peroxidation damage and inflammation, yet the underlying mechanisms remain unclear.

DNA2, a multifunctional enzyme with structure-specific nuclease, 5 -to-3 helicase, and DNA-dependent ATPase activities, plays a pivotal role in the cellular response to DNA damage. However, its involvement in cerebral ischemia/reperfusion (I/R) injury remains to be elucidated. This study investigated the involvement of DNA2 in cerebral I/R injury using conditional knockout (cKO) mice ( -Cre) subjected to middle cerebral artery occlusion (MCAO), an established model of cerebral I/R.

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.
