Project description:The consequences of cardiac arrest are often fatal, including brain injury after resuscitation. It has been reported that few people patients can recover to the neurological state before cardiac arrest. MiRNAs are short non-protein-coding RNA molecules that are evolutionarily conserved and ubiquitously expressed. Numerous pieces of research have reviewed the role of miRNAs in regulating neuronal apoptosis, regeneration, and plasticity of neurons, and inflammatory after cardiac arrest . As the stability of miRNAs in the bloodstream and the function in the regulation of neurological impairment after ischemia-reperfusion injury, microRNAs have been the most potential new biomarkers and therapeutic targets after cardiac arrest to alleviate neurological impairment . In this work, we found that the level of miR-483-5p is correlated to the prognosis of neurological function. To investigate the function of miR-483-5p on neurons after ischemia-reperfusion injury,we established highly differentiated PC12 cell lines in which miR-483-5p was overexpressed by transfection with miR-483-5p mimcis.We then performed gene expression profiling analysis using data obtained from RNA-seq of PC12 cells in different groups.

Project description:Prediction of neurological outcomes shortly after cardiac arrest would represent a major breakthrough. We tested the ability of gene expression profiles of blood cells to predict outcome in cardiac arrest patients. 35 consecutive cardiac arrest patients treated with therapeutic hypothermia (33°C for 24h) were included in this prospective monocentre study. Cerebral Performance Category (CPC) was determined at discharge and 6 months later. All patients had blood sampling at the end of hypothermia. Gene expression profiles of blood cells were determined using 25,000~gene microarray in two groups of patients: good outcome (CPC 1-2) and bad outcome (CPC 3-5).

Project description:Circulating microRNAs to predict neurological outcome after sudden cardiac arrest
| PRJNA151255 | ENA
Project description:Background: Cardiac arrest (CA) represents the third leading cause of death worldwide. Among survivors, severe neurological sequelae are frequent but difficult to predict. Novel prognostic biomarkers would offer clinicians the possibility to deliver personalized healthcare. The potential of small circulating noncoding RNAs (microRNAs) to predict neurological outcome and survival after CA has been reported. Objective: This study aims to identify circulating circular RNAs (circRNAs) associated with clinical outcome after CA. Methods and Results: Methods and Results: Whole blood samples obtained 48h after return of spontaneous circulation from 23 sex-matched survivors and 23 deceased cardiac arrest (CA) patients were enrolled in this study. Whole transcriptome RNA sequencing identified candidate RNAs associated with neurological outcome and survival. Conclusion: We have identified candidate RNAs associated with clinical outcome after CA whose predictive value remains to be confirmed in large populations.

Project description:Cardiac arrest (CA) represents a significant public health concern, placing a substantial burden on the healthcare system. Post-restoration of autonomous circulation, a majority of patients encounter myocardial dysfunction, a primary cause of death in individuals with cardiac arrest. Hence, the identification of novel therapeutic approaches to enhance myocardial resilience in high-risk cardiac arrest patients holds immense clinical importance. Cold-inducible RNA-binding protein (CIRBP) serves as a vital player in cellular protection and stress resistance, induced by cold conditions. Studies have indicated that the elevation of CIRBP through its agonists can impede the progression of heart failure. However, its role in cardiac toxicity prompted by cardiac arrest remains ambiguous. This study delves into investigating the protective mechanism of CIRBP on cardiac function post-cardiac arrest and sheds light on potential target genes regulated by CIRBP via transcriptome sequencing. Our research outcomes highlight the robust cardioprotective impact of CIRBP on cardiac dysfunction triggered by cardiac arrest and resuscitation.

Project description:Acute cardiorenal syndrome (CRS-1) is a morbid complication of acute cardiovascular disease. Mechanistic investigations have focused on intrarenal cellular signaling induced by ischemia/reperfusion. Additional signals, “cardiorenal connectors”, have been postulated, but investigation in CRS-1 has been limited by a paucity of animal models and technical limitations precluding discovery studies of glomerular filtrate. To address these limitations we developed a translational model of CRS-1, cardiac arrest and cardiopulmonary resuscitation (CA/CPR) and now report findings from a nanoscale mass spectrometry assay allowing proteomic exploration of Bowman’s space aspirate 2h after CA/CPR or sham procedure. Imaging, molecular weight and charge distribution, and minimal contribution of proteins from surrounding cell types confirmed the acquisition of filtrate. We detected filtration of low-molecular weight proteins specific to the heart following CA/CPR. Additional mass spectrometry performed on 24h urine collections from mice with deficient tubular endocytosis confirmed CA/CPR-specific cardiac protein filtration, and identified a novel, CA/CPR-specific, filtrate component: Cardiac LIM protein. Cardiac arrest-induced plasma release of Cardiac LIM protein occurred in mice and in critically-ill human cardiac arrest survivors and administration of recombinant cardiac LIM protein to mice altered renal function. Our findings demonstrate that glomerular filtrate is accessible to nanoscale proteomics and elucidate the population of proteins filtered 2h after acute cardiovascular crisis. The presence and identification of cardiac-specific proteins in renal filtrate suggest a potential novel signaling mechanism in CRS-1. We expect these findings to advance understanding of cardiorenal syndrome.

Project description:Biomarkers to more accurately determine severity and prognosis following spinal cord injury (SCI) are needed to ensure that patients are assigned to the most suitable treatment and rehabilitation regimes. This study aimed to characterise the blood proteome following SCI in clinical rat injury models to identify novel candidate biomarkers and altered biological pathways.
