Project description:Edaravone dexborneol (EDB) is widely recognized for its anti-inflammatory and antioxidant properties and is clinically applied in the treatment of acute cerebral infarction. Ferroptosis is a critical process in the pathophysiology of brain injury following intracerebral hemorrhage (ICH). However, it remains unclear whether EDB can ameliorate ICH through the modulation of ferroptosis. This study aimed to evaluate the function and mechanism of EDB in treatment of ICH. With a rat ICH model, animal behavior tests, histopathological staining, magnetic resonance imaging and evans blue staining were used to evaluate the neural protective function of EDB on ICH rats. The potential molecular mechanism was investigated using RNA sequencing. With the administration of Fer-1, a range of ferroptosis-related biomarkers, including Fe2+, 4-hydroxynonenal, malondialdehyde, etc., were analyzed to to ascertain whether EDB confers neuroprotective effects through the modulation of P53/GPX4 pathways to inhibit ferroptosis. Finally, the findings were further corroborated using an in vitro ICH model with a P53 inhibitor. EDB has the potential to markedly enhance nerve and motor function, mitigate pathological damage, facilitate hematoma clearance, and repair BBB injury in ICH rats. KEGG analysis revealed that the differentially expressed genes were associated with signaling pathways, including P53 and ferroptosis. Both EDB and Fer-1 substantially reduced the concentrations of Fe2+, 4-hydroxynonenal, malondialdehyde, increased the amount of anti-oxidants, decreased the expression of P53, and concurrently upregulated the expression of GPX4. Besides, the P53 inhibitor PFT-α was observed to significantly reduce the levels of 4-HNE and lipid peroxides, while concurrently increasing the expression of GPX4. This investigation has shed light on the crucial neuroprotective role of EDB by regulating ferroptosis in ICH disease, which provided a theoretical basis for the clinical application of EDB in the treatment of ICH.

Project description:Intracerebral hemorrhage (ICH) is a life-threatening condition associated with significant morbidity and mortality. Understanding the molecular mechanisms underlying ICH and its severe form is crucial for developing effective therapeutic strategies. This study investigates transcriptomic alterations in rodent models of ICH and severe intracerebral hemorrhage to shed light on the genetic pathways involved in hemorrhagic brain injury. We performed principal component analysis, revealing distinct principal component segments of normal rats compared to intracerebral hemorrhage and severe intracerebral hemorrhage rats. We further employed heatmaps and volcano plots to identify differentially expressed genes and utilized bar plots and KEGG pathway analysis to elucidate the different molecular pathways involved. Using comprehensive RNA sequencing and bioinformatics analyses, we identified a multitude of differentially expressed genes in both the ICH and severe ICH models. Our results revealed 5679 common genes among the normal, intracerebral hemorrhage, and severe intracerebral hemorrhage groups in the upregulated genes group, and 1196 common genes in the downregulated genes. A volcano plot comparing the groups further highlighted common genes, including PDPN, TIMP1, SERPINE1, TUBB6, and CD44. These findings underscore the complex interplay of genes involved in inflammation, oxidative stress, and neuronal damage. Furthermore, pathway enrichment analysis uncovered key signaling pathways, including the TNF signaling pathway, protein processing in the endoplasmic reticulum, MAPK signaling pathway, and Fc gamma R-mediated phagocytosis, implicated in the pathogenesis of ICH.

Project description:To identify the potential lncRNA and mRNA post intracerebral hemorrhage (ICH), we have employed lncRNA microarray expression profiling. 570 mRNAs and 313 lncRNAs were identified in the ICH vs sham group .Expression of six mRNA (Saa3, Col10a1, Mmp13, Oxt, Pcdhb6 and Resp18) and lncRNA (ENSMUT00000141700, AK143011, ENSMUT00000128306, AK030988, ENSMUST00000187076 and ENSMUST00000134129) from this signature was quantified by qPCR.

Project description:Transfer-RNA-Derived Small RNA (tsRNA) is s a novel class of short non-coding RNA including stress-induced tRNA fragments (tiRNA) and tRNA-derived fragments (tRF). Using RNA sequencing, we evaluated the tsRNA expression profiles in the brain of intracerebral hemorrhage (ICH) and sham rats at days 21. Meanwhile, tsRNA levels in ICH treated with the Traditional Chinese Medicine named Buyang Huanwu Decoction (BYHWD) were detected. Bioinformatics analyses indicated that tsRNAs were the important regulators in ICH and potential new therapeutic targets of BYHWD.

Project description:To investigate age-dependent transcriptomic changes between young or aged intracerebral hemorrhage mice, we established collagenase IV-induced intracerebral hemorrhage mice models. Intracerebral hemorrhage was induced by infusion of sterile collagenase IV in ipsilateral caudate putamen of brain. We then performed gene expression profiling analysis using data obtained from RNA-seq of brain perihematomal tissues from young or aged ICH mice 24 hours after intracerebral hemorrhage.

Project description:We aimed to investigate the microbial community composition in patients with intracerebral hemorrhage (ICH) and its effect on prognosis. The relationship between changes in bacterial flora and the prognosis of spontaneous cerebral hemorrhage was studied in two cohort studies. Fecal samples from healthy volunteers and patients with intracerebral hemorrhage were subjected to 16S rRNA sequencing at three time points: T1 (within 24 hours of admission), T2 (3 days post-surgery), and T3 (7 days post-surgery) using Illumina high-throughput sequencing technology.

Project description:Intracerebral hemorrhage (ICH) is a severe neurological disorder with no proven treatment. While there is substantial interest in post-ICH neuroinflammation and associated pathophysiological mechanisms, these processes remain poorly understood. To further advance our understanding, we performed RNA-seq in the peripheral blood of ICH patients to test the hypothesis that ICH would induce inflammatory biological pathways. 16,640 genes were identified and 216 were significant DEGs after ICH (FDR<0.1). IPA identified three canonical pathways as the most statistically significantly activated by ICH: colorectal cancer metastasis signaling (Z-score 3.00, P=1.71E-5), interleukin-8 (IL-8) signaling (3.00, 8.44E-5), and nuclear factor-kappa B (NF-kB) activation by viruses (2.55, 1.78E-4). Inflammatory mediators of particular relevance included IL-8, NF-kB, ERK 1/2, and the integrins β3, α2b, and β5. Conclusion: ICH induced peripheral blood gene expression at 72 to 96 hours compared with 0 to 24 hours from symptom onset. DEGs that were highly expressed in the significant biological pathways included those related to inflammation and activation of the immune response. Further research is needed to determine if these changes affect outcomes and may represent new therapeutic targets.
