The occurrence of severe myocardial ischemia/reperfusion (I/R) injury is associated with the clinical application reestablishment technique for heart disease, and understanding its underlying mechanisms currently an urgent issue. Prior investigations have demonstrated potential enhancement MIRI through EGR1 suppression, although precise regulatory pathways require further elucidation. core focus this investigation to examine molecular regulates mitophagy-mediated cell pyroptosis impact on MIRI. Cardiomyocyte hypoxia/reoxygenation (H/R) models mouse I/R were used investigate involvement in regulating injury. research outcomes that under H/R conditions, expression was upregulated inhibited JAK2/STAT3 pathway, leading enhanced mitophagy disrupted mitochondrial fusion/fission dynamics, ultimately resulting pyroptosis. Further revealed upregulation mediated by methyltransferase like 3 (METTL3)-mediated m6A modification mRNA depended binding insulin growth factor 2 mrna protein (IGF2BP2) N6-methyladenosine (m6A) site enhance stability. In vivo animal experiments confirmed METTL3 IGF2BP2 suppressed activation janus kinase (JAK2) /signal transducer activator transcription (STAT3) thereby inhibiting mitophagy, disrupting promoting pyroptosis, exacerbating

Abstract Postoperative cognitive dysfunction (POCD) is a frequent neurological complication encountered during the perioperative period with unclear mechanisms and no effective treatments. Recent research into pathogenesis of POCD has primarily focused on neuroinflammation, oxidative stress, changes in neural synaptic plasticity neurotransmitter imbalances. Given high-energy metabolism neurons their critical dependency mitochondria, mitochondrial directly affects neuronal function. Additionally, as primary organelles generating reactive oxygen species, mitochondria are closely linked to pathological processes neuroinflammation. Surgery anesthesia can induce dysfunction, increase disrupt quality-control via various pathways, hence serving key initiators process. We conducted review role potential postoperative by consulting relevant literature from PubMed EMBASE databases spanning past 25 years. Our findings indicate that surgery inhibit respiration, thereby reducing ATP production, decreasing membrane potential, promoting fission, inducing calcium buffering abnormalities iron accumulation, inhibiting mitophagy, increasing stress. Mitochondrial damage ultimately lead impaired function, abnormal transmission, synthesis release neurotransmitters, even death, resulting dysfunction. Targeted therapies have shown positive outcomes, holding promise novel treatment for POCD.

Ferroptosis, a form of programmed cell death featured by lipid peroxidation, has been proposed as potential etiology for postoperative cognitive dysfunction (POCD). Myocyte-specific enhancer factor 2C (MEF2C), transcription expressed in various brain types, implicated disorders. This study sought to ascertain whether MEF2C governs capacity affecting ferroptosis.

Abstract Background Synaptosomal-associated protein 25 (SNAP25) exerts protective effects against postoperative cognitive dysfunction (POCD) by promoting PTEN-induced kinase 1 (PINK1)/Parkin-mediated mitophagy and repressing caspase-3/gasdermin E (GSDME)-mediated pyroptosis. However, the regulatory mechanisms of SNAP25 remain unclear. Methods We employed recombinant adeno-associated virus 9 (AAV9)-hSyn to knockdown tumor necrosis factor α-induced (TNFAIP1) or investigate role TNFAIP1 in POCD. Cognitive performance, hippocampal injury, mitophagy, pyroptosis were assessed. Co-immunoprecipitation (co-IP) ubiquitination assays conducted elucidate which stabilizes SNAP25. Results Our results demonstrated that ubiquitin ligase was upregulated hippocampus mice following isoflurane (Iso) anesthesia laparotomy. The N-terminal region (residues 1–96) formed a conjugate with SNAP25, leading lysine (K) 48-linked polyubiquitination at K69. Silencing enhanced SH-SY5Y cell viability conferred antioxidant, pro-mitophagy, anti-pyroptosis properties response Iso lipopolysaccharide (LPS) challenges. Conversely, overexpression reduced HT22 viability, increased reactive oxygen species (ROS) accumulation, impaired PINK1/Parkin-dependent induced caspase-3/GSDME-dependent suppressing expression. Neuron-specific ameliorated POCD, restored pyroptosis, reversed depletion. Conclusions In summary, our findings inhibiting TNFAIP1-mediated degradation might be promising therapeutic approach for mitigating decline.

Traumatic brain injury (TBI) can generally be divided into focal damage and diffuse damage, neonate Hypoxia-Ischemia Brain Damage (nHIBD) is one of the causes damage. Patients with nHIBD are at an increased risk developing Alzheimer's disease (AD). However, shared pathogenesis patients affected both neurological disorders has not been fully elucidated. We here aim to identify molecular signatures between AD. used integrated analysis cortex gene expression data, targeting differential genes related mechanisms neurodegeneration cognitive impairment following traumatic injury. The profiles (GSE203206) that Neonate (GSE23317) were obtained from Gene Expression Omnibus (GEO) database. After identifying common differentially expressed (DEGs) by limma package analysis, five kinds analyses performed on them, namely Ontology (GO) pathway enrichment protein-protein interaction network, DEG-transcription factor interactions DEG-microRNA interactions, protein-drug protein-disease association gene-inflammation protein-inflammation analysis. In total, 12 DEGs identified including HSPB1, VIM, MVD, TUBB4A, AACS, ANXA6, DIRAS2, RPH3A, CEND1, KALM, THOP1, AREL1. also 11 hub proteins, three central regulatory transcription factors, microRNAs encoded DEGs. Protein-drug showed CYC1 UQCRFS1 associated different drugs. Gene-disease shows Mammary Neoplasms, Neoplasm Metastasis, Schizophrenia, Ischemia diseases most relevant proteins we identified. Gene-inflammation AREL1 inflammatory response, while AKT1 MAPK14 response. This study provides new insights AD nHIBD. These pathways could potentially design therapeutic interventions, reducing likelihood development in survivors neonatal Hypoxic-Ischemia

Perioperative neurocognitive disorder (PND) is a common neurological complication after surgery/anesthesia in elderly patients that affect postoperative outcome and long-term quality of life, which increases the cost family social resources. The pathological mechanism PND complex not fully understood, methods prevention treatment are very limited, so it particularly important to analyze PND. Research indicates mitochondrial dysfunction pivotal initiation progression PND, although precise mechanisms remain elusive could involve disrupted mitophagy. We reviewed recent studies on link between mitophagy highlighting role key proteins abnormal discussing therapeutic strategies aimed at regulation. This provides insights into underlying potential targets.
