Therefore, we aimed to develop a reliable system for accurate assessment of ITD mutations of various size ranges and improve prognosis for AML. Bone marrow samples from AML patients from December 2021 to March 2022 were collected for methodology establishment. After a large-scale sample testing by next-generation sequencing (NGS), a short-read tandem duplication recognition system based on soft-clip was established. During performance validation, the lower detection limit was set to a parameter close to capillary electrophoresis (\"gold standard\") by adjusting reference values (sensitivity 3-5%). Data simulation was performed using the FLT3 gene CDS as wild-type data. Methodological concordance of this system with capillary electrophoresis was analyzed. The applicability to other pathogenic tandem duplication mutations was validated. We have developed an innovative NGS-based system named \"ITDFinder\" for accurate detection of ITD mutations, with the lower detection limit of 4%, corresponding to a sequencing depth of 1000X. Compared to capillary electrophoresis, ITDFinder exhibited good consistency (mean difference: -0.0085) in mutation detection and correlation across various length of ITD. Clinical case validation (n = 1,032) showed an overall agreement rate of 96.5% between the two approaches used for characterization. In addition, data simulation results suggested that the new system could observe BCOR-ITD and KMT2A-PTD mutations (depths, 500-1300X; mutation rates, 0.04-0.8). The innovative mutation detection system is appropriate to small-to large-sized ITDs and other pathogenic tandem duplication mutations, expected to save 96.3% of the workload.

A new research direction may be to explore peripheral atherosclerotic biomarkers from the perspective of mitochondrial dysfunction, which can induce inflammatory cell activation. Moreover, the degree of overall cervicocephalic atherosclerosis (namely, atherosclerotic burden) is more closely related to AIS prognosis than local atherosclerotic lesions. Therefore, this study investigated the relationship between mitochondrial dysfunction in peripheral blood mononuclear cells (PBMCs), including monocytes and lymphocytes, and overall cervicocephalic atherosclerotic burden and AIS outcome. Patients with AIS and cervicocephalic atherosclerosis were enrolled and followed up for 90 days. The reactive oxygen species (ROS) and the mitochondrial deoxyribonucleic acid copy number (mtDNA-CN) in PBMCs were measured respectively through a fluorescence probe and a droplet digital polymerase chain reaction to evaluate mitochondrial function. The overall intracranial and cervical atherosclerotic burden (ICAB) was quantified by summing up the atherosclerosis degree points in each arterial segment as assessed by computed tomography angiography. A modified Rankin Scale (mRS) score >2 was considered a 90-day unfavorable functional outcome. Five (4.9%) of the 103 patients with AIS were lost to follow-up. mtDNA-CN [adjusted β = -0.099, 95% confidence intervals (CIs) = -0.153 ∼ -0.044, <i>p</i> < 0.001] and ROS content (adjusted β = 1.275, 95%CI = 0.885 ∼ 1.665, <i>p</i> < 0.001) were correlated with ICAB.

The pain decreases when these cells down-regulate genes supporting the pro-inflammatory state, up-regulate genes for expressing anti-inflammatory factors, and modulate genes that reduce nociceptive neuron spontaneous electrical activity. Pharmacological agents, the primary technique for reducing pain, do not eliminate pain, and <50% of patients achieve benefits because they do not address the underlying causes of pain. Alternative techniques providing longer lasting, but not complete or long-term pain relief include surgical interventions, electrical stimulation, and antibody treatment.

We determined the dose dependent effects and temporal relationships between fentanyl exposures and NSC health, viability, and differentiation. Markers of mitochondrial health [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetra-zolium bromide (MTT)] and cell death/damage [lactate dehydrogenase (LDH)] were monitored to determine the dose response effects of fentanyl on NSC viability. In addition, lipidomics analysis was conducted to investigate lipid profile changes in differentiated neural cells treated with fentanyl. Fentanyl did not cause a significant increase in LDH release, nor MTT reduction after 24-h exposure at concentrations of 0.5, 1.0, 3.0, 10, or 100 μM, for both NSCs and differentiated neural cells.

When consumed by pregnant women, CBD can pass through the placenta and enter the fetal blood stream. There is concern over adverse effects of fetal exposure to CBD and its major metabolites (7-OH-CBD and 7-COOH-CBD). In the present study, human neural stem cells (NSCs) were treated with CBD and its metabolites at different concentrations for various durations to understand how the drug may affect fetal brain development. NSCs were also treated with delta-9 tetrahydrocannabinol (THC) for comparison purposes. CBD, 7-OH-CBD and 7-COOH-CBD dose-dependently reduced NSC viability. CBD and 7-OH-CBD reduced NSC number at the G1 phase. A 24 h exposure did not cause significant change in NSC proliferation. At concentrations comparable to those detected in human blood, longer exposures to CBD, 7-OH-CBD and 7-COOH-CBD caused more obvious cell death. After NSCs differentiation, CBD treatment reduced GFAP and cannabinoid receptor 2 (CB2) expression. THC treatment reduced the GFAP expression, but the change in CB2 expression did not reach statistical significance. The expression of cannabinoid receptor 1 (CB1) and beta-tubulin III were not significantly altered by drug exposures. The study demonstrated that clinically relevant concentrations of CBD, 7-OH-CBD and 7-COOH-CBD affect basic physiological features of human NSCs. After NSC differentiation, the reduced expression of CB2 receptors and GFAP on differentiated cells further indicated the vulnerability of developing central nervous system to CBD and THC. These data will help to contextualize <i>in vivo</i> neurodevelopmental studies that may not accurately model human metabolite profiles of CBD.</p>","PeriodicalId":12163,"journal":{"name":"Experimental Biology and Medicine","volume":"250 ","pages":"10608"},"PeriodicalIF":2.8,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12203246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144527082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
