It disrupts brain development, particularly affecting the hippocampus, which is vulnerable to alcohol-induced oxidative stress, resulting in impaired neuronal signalling, increased cell death, and reduced neurogenesis. Simvastatin, a cholesterol-lowering drug, has neuroprotective and antioxidant effects, but its potential in protecting against alcohol-related brain damage is unclear. This study examined the protective effects of Simvastatin in four-week-old C57BL/6J mice administered 20% alcohol (intraperitoneal, i.p.), 5 or 15 mg/kg Simvastatin orally, followed by 20% alcohol (i.p.) or the controls (i.e., 5 mg/kg Simvastatin only or no treatment). After 28 days, the harvested brains underwent biochemical or immunohistochemical (IHC) analysis. Biochemical analyses measured malondialdehyde (MDA) levels, glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activity in homogenised hippocampal samples and IHC involved immunolabelling for PcNA or DCX. PcNA- or DCX-positive cells in the suprapyramidal blade of the dentate gyrus were counted using QuPath software. Alcohol elevated GSH-Px activity, indicating oxidative damage, but both Simvastatin concentrations reduced this, with 15 mg being more effective in females. MDA level and SOD activity remained unchanged. Simvastatin at 5 mg reduced alcohol's effect on PcNA-positive cells in both sexes, while 15 mg was more effective in females. For DCX-positive cells, 5 mg Simvastatin was protective in both sexes, but 15 mg showed no effect. Overall, Simvastatin exhibited antioxidant and neuroprotective effects against alcohol-induced hippocampal damage, suggesting its potential for treating alcohol-related brain disorders.","PeriodicalId":18685,"journal":{"name":"Metabolic brain disease","volume":"40 6","pages":"239"},"PeriodicalIF":3.5,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12241278/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144591703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An in vivo ICH model was created by injecting type IV collagenase into the basal ganglia of Sprague-Dawley (SD) rats. The cell/rat models were treated with NBP and/or stattic. The expression of STAT3, miR-7-5p, EGFR, PI3K, AKT, p-AKT, AKT2, AKT3, and AQP4 were assessed using qRT-PCR, Western blotting, and immunofluorescence. Brain water content was measured using the wet-to-dry weight method, and neurological deficits were evaluated using the NSS (neurological severity score).Results: In both the CTX-TNA2 ICH model and the rat ICH model, miR-7-5p expression was significantly reduced, while STAT3, EGFR, AKT, p-AKT, AKT2, AKT3, and AQP4 expression were elevated compared to the blank/sham-operated group. NBP increased the expression of STAT3 and miR-7-5p, while reducing the expression of EGFR, AKT, p-AKT, AKT2, AKT3, and AQP4. NBP also decreased brain water content and improved NSS scores. STAT3 inhibition significantly reduced STAT3 and miR-7-5p expression, increased the expression of EGFR, PI3K, AKT, p-AKT, AKT2, AKT3, and AQP4, and elevated brain water content. NBP can reverse the downregulation of STAT3 and miR-7-5p expression, the upregulation of EGFR/PI3K/AKT axis and AQP4 expression, and the increase in brain water content induced by STAT3 inhibition.Conclusion: NBP alleviates cerebral edema after ICH by upregulating STAT3 expression, thereby increasing miR-7-5p levels and inhibiting the EGFR/PI3K/AKT axis and AQP4 expression.","PeriodicalId":18685,"journal":{"name":"Metabolic brain disease","volume":"40 6","pages":"238"},"PeriodicalIF":3.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144540867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aqueous leaf extract of Talinum triangulare (AETT) is used in traditional medicine in the treatment of various kinds of diseases. This study sought to examine neuroprotective potential of AETT on cadmium-induced neurotoxicity in rats. Neurotoxicity was induced in rats via oral administration of 5 mg/kg body weight CdCl2 and treated with either 200 mg/kg of AETT or vitamin E for 14 consecutive days. Results revealed that Cd induced behavioural incompetence with marked decrease in motor skills, muscle strength, exploratory activities, and anxiogenic-like phenotype which are vital psychomotor coordination tools. Cd intoxication caused a marked increase in neuronal expression of inflammatory biomarkers (TNF-α, MPO and NO), hydrogen peroxide generation, and lipid peroxidation; with associated decrease in both enzymatic antioxidants (GST, SOD, CAT) and non-enzymatic antioxidants (reduced glutathione). Similarly, decreased in dopamine with concomitant increased in the activity of acetylcholinesterase were observed in Cd-induced rats. Nevertheless, AETT or vitamin E markedly restored behavioural competence, mitigated neuroinflammation, lipid peroxidation and oxidative stress. AETT modulated cholinergic and dopaminergic pathways which improved bioavailability of acetylcholine and dopamine in the brain. Furthermore, AETT displayed better protective effects than vitamin E, this could be because of antioxidant phytochemicals in AETT as showed in the GCMS result. Overall, this study suggested AETT as a potential therapeutic agent in the treatment of neurotoxicity mediated by toxic metals.","PeriodicalId":18685,"journal":{"name":"Metabolic brain disease","volume":"40 6","pages":"237"},"PeriodicalIF":3.5,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These biomechanical insults initiate a complex cascade of secondary injury processes, including neuronal cell death, neuroinflammation, oxidative stress, microglial activation, and blood-brain barrier dysfunction. These events contribute to the loss of homeostasis in both the central and peripheral nervous systems. Importantly, these pathophysiological changes may extend beyond the acute phase, often evolving into chronic conditions that can persist for years after the initial injury. In addition, TBI can cause fractures of the skull base and predispose to CSF leak and CSF fistula, which contribute to the contraction of bacteria. Surgical interventions, invasive devices, and prolonged immobilization are other factors that predispose patients to develop an infection secondary to TBI. Among the infections developed secondarily by patients with TBI are meningitis, pneumonia, and urinary tract infections, which can progress to Systemic Inflammatory Response Syndrome (SIRS) and sepsis. Furthermore, immunosuppression due to the lack of components of the cellular immune response, particularly neutrophils, helper T cells, regulatory T cells, and natural killer (NK) cells, demonstrates the pathophysiological heterogeneity of TBI, which can result in complications involving the central nervous system (CNS) and peripheral nervous system (PNS).

However, the implications of this compound on neurological disorders remain inadequately elucidated. Recently, our research team has elucidated the neuroprotective properties of ivermectin administered in three doses following cerebral ischemia/reperfusion (IR). The objective of the current investigation is to ascertain whether ivermectin sustains its neuroprotective properties through prolonged administration in models of cerebral IR in rats, as well as to evaluate its impact on the formation of neutrophil extracellular traps (NETs). A rat model of transient global cerebral IR was induced by occluding both carotid arteries for 20 min. Ivermectin (2 mg/kg/day) was administered intraperitoneally one hour after the induction of cerebral ischemia for 7 consecutive days at 24-hour intervals. Then, the effects of ivermectin on brain infarct size, blood cell profile, bleeding time, memory and learning, balance and motor coordination, myeloperoxidase enzyme activity, and H3cit protein levels were investigated. The finding showed that the administration of ivermectin for 7 days did not improve memory and learning, blood parameters, or cerebral infarct size. However, it caused a 25.4% reduction in citrullinated histone protein level, decreased myeloperoxidase activity (P = 0.017), and improved balance and motor coordination (P = 0.017 and P = 0.024). In conclusion, our findings indicate that prolonged administration of ivermectin may diminish its neuroprotective effects and its effects can differ depending on the drug regimen.","PeriodicalId":18685,"journal":{"name":"Metabolic brain disease","volume":"40 6","pages":"234"},"PeriodicalIF":3.5,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144485098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, some health benefits have been suggested for rTFAs. Here, with the goal of contrasting the effects of iTFAs with rTFAs, we fed adult mice for 45 days with 168 mg/kg of trans-elaidic acid (TEA, an iTFA) or trans-vaccenic acid (TVA, an rTFA), and evaluated their serum lipid profile and their performance in an appetitive memory task. We found marked differential effects, while TEA showed strong atherogenic effects (p < 0.0001 for cholesterol, triglycerides, VLDL, LDL, and HDL versus control), TVA showed significant opposite effects than TEA (p < 0.0001 for cholesterol, triglycerides, LDL, and HDL; p = 0.0039 for VLDL). Furthermore, when these mice were trained to find a piece of feed in a slightly intricate eight-arm maze, TEA showed impairing effects on appetitive memory. Although TEA intake did not block appetitive memory, there was a clear delay in learning (p = 0.0353 versus control). Notably, TVA improved the learning performance of mice (p < 0.0001 versus control). Moreover, oleic acid, a cis isomer, showed similar effects than TVA in the appetitive learning task (p = 0.0004).

This study aimed to explore the influence of Tan (tanshinone) IIA in the treatment of neuronal ferroptosis induced by CI/RI, along with the associated molecular mechanisms. A CI/RI model was created by occluding the middle cerebral artery in rats (MCAO/R). A cellular CI/RI model was established with SH-SY5Y cells that were subjected to oxygen‒glucose deprivation followed by subsequent reperfusion (OGD/R). The optimal concentration for maintaining cell viability was evaluated through the CCK-8 assay. The expression levels of ferroptosis and oxidative stress-related genes in rat brain tissue and SH-SY5Y cells were determined, and the molecular mechanism by which Tan IIA regulates ferroptosis during CI/RI treatment was verified by bioinformatics analysis, RT‒qPCR, and dual-luciferase reporter assays. The results revealed that Tan IIA relieved CI/RI injury and inflammation by inhibiting ferroptosis in MCAO/R rat brain neurons. Our experimental results demonstrated that Tan IIA suppressed the progression of OGD/R and alleviated inflammation in SH-SY5Y cells. Ferroptosis affected the concentrations of Fe2+, ROS, and MDA in the CI/RI model while simultaneously increasing the expression of miR-449a. In terms of the molecular mechanism, Tan IIA inhibited OGD/R-induced neural ferroptosis, and this mechanism of action may involve Tan IIA promoting the downregulation of ACSL4 expression by targeting miR-449a within cells, thereby inhibiting ferroptosis in cells induced by OGD/R. Our research results indicate that Tan IIA relieved CI/RI injury and inflammation by alleviating neuronal ferroptosis, and this regulatory effect may be achieved through the miR-449a/ACSL4 molecular axis.","PeriodicalId":18685,"journal":{"name":"Metabolic brain disease","volume":"40 6","pages":"231"},"PeriodicalIF":3.5,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
