MetabolomicsActivation of imprinted gene Pw1 promotes cardiac fibrosis after ischemic injury

Cardiac fibrosis, characterized by excessive extracellular matrix (ECM) deposition in the myocardium, is a critical target for heart disease treatments. Pw1 (paternally expressed gene 3) is an imprinted gene expressed from the paternally allele, and de novo purine biosynthesis (DNPB) is a crucial...

MetabolomicsThe dynamic changes and mechanism of no reflow injury after myocardial ischemia-reperfusion
This study aims to investigate the dynamic changes and correlation of no-reflow (NR) injury following myocardial ischemia and reperfusion, and to explore the underlying mechanism of NR injury through transcriptomic and metabolomic analysis. Methods: Healthy male SD rats were divided into two batches...

MetabolomicsTRIM47 promotes cardiac ischemia/reperfusion injury
This study shows that TRIM47 is upregulated in cardiomyocytes during cardiac I/R injury in an EGR1-dependent manner, correlating with injury severity. Cardiomyocyte-specific TRIM47 overexpression worsens, while TRIM47 knockout alleviates, I/R-induced cardiac injury and dysfunction. Mechanistically, ...

MetabolomicsUntargeted Metabolomics Reveals a Mild Impact of Remote Ischemic Conditioning on the Plasma Metabolome and α-Hydroxybutyrate as a Possible Cardioprotective Factor and Biomarker of Tissue Ischemia
Remote ischemic conditioning (RIC) is a maneuver by which short non-lethal ischemic events are applied on distant organs or limbs to reduce ischemia and reperfusion injuries caused by e.g. heart attacks. As RIC can be induced using a simple blood pressure cuff e.g. prior to revascularization, it con...

MetabolomicsMongolian medicine Wulanwendusu-11 ameliorates myocardial ischemia-reperfusion injury in association with the modulation of intestinal microbiota and associated metabolic pathways

Abstract

Objective: Wulanwendusu-11 (WLWDS-11), a traditional Mongolian medicinal formula, is commonly used for the treatment of Cardiovascular diseases. However, its therapeutic material basis and in vivo metabolic profile in the context of chronic myocardial ischemia-reperfusion injury (M...

MetabolomicsMetabolomic data related to the alleviation of cardiac ischemia/reperfusion injury by NADPH derived from pentose phosphate pathway

Exercise promotes physiological cardiomyocyte growth and protects against ischemia/reperfusion (I/R) injury in the heart. The molecular mechanism by which exercise benefits cardiac metabolism and function remains largely unknown. Exercise (swimming or treadmill)-induced physiological hypertrophy ...

TranscriptomicsDifferential Gene Regulation during murine in vivo heart ischemia comparing wildtype and Per2 deficient mice
Disruption of peripheral circadian rhyme pathways dominantly leads to metabolic disorders. Studies on circadian rhythm proteins in the heart indicated a role for Clock or Per2 in cardiac metabolism. In fact, Per2-/- mice have larger infarct sizes with a deficient lactate production during myocardial...

MetabolomicsIntraoperative intestinal ischemia-reperfusion injury aggravates postoperative delirium by remodeling gut microbiota
Postoperative delirium, is a notable and serious complication after surgery, commonly extending hospitalization by 2-3 days. In a cohort of 167 patients, elevated serum intestinal fatty acid binding protein (I-FABP) was identified as an independent risk factor for postoperative delirium. Complementa...

TranscriptomicsCaM Kinase II mediates maladaptive post-infarct remodeling but not acute myocardial ischemia/reperfusion injury
Calcium/calmodulin-dependent protein kinase II (CaMKII) was suggested to mediate ischemic myocardial injury and adverse cardiac remodeling. However, the specific functions of the CaMKII isoforms and splice variants in ischemia/reperfusion (I/R) injury have not been investigated yet. Thus, we studied...

MetabolomicsMetabotyping Patients' Journeys Reveals Early Predisposition to Lung Injury after Cardiac Surgery
Cardiovascular disease is the leading cause of death worldwide and patients with severe symptoms undergo cardiac surgery. Even after uncomplicated surgeries, some patients experience postoperative complications such as lung injury. We hypothesized that the procedure elicits metabolic activity that c...
