Alcohol use disorder (AUD) is a major component in the etiology of cognitive decline and dementia. Underlying mechanisms by which long-term alcohol abuse causes dysfunction include excessive oxidative stress inflammation brain, activated increased reactive oxygen/nitrogen species (ROS/RNS), advanced glycation end-products (AGEs) high-mobility group box 1 protein (HMGB1). In pilot study, we examine potential clinical value circulating biomarkers including ROS/RNS, HMGB1, soluble receptor for AGE (sRAGE), brain biomarker aging apolipoprotein D (ApoD), antioxidant regulator nuclear factor erythroid 2-related 2 (NRF2) as predictive indices impairment (CI) abstinent patients with AUD (n = 25) compared to established Alzheimer’s disease (AD, n 26) control subjects 25). Plasma concentrations sRAGE were evaluated immunoblotting; ROS/RNS fluorometric kit; ApoD, NRF2 ELISA. Abstinent had higher sRAGE, (p < 0.05), ApoD 0.01) concentrations, similar those AD patients, lower controls. These changes remarkable CI. correlated positively duration (rho 0.398, p 0.022; rho 0.404, 0.018), whereas negatively periods abstinence −0.340, 0.045).

Neuropsychiatric disorders (NDs) are a diverse group of pathologies, including schizophrenia or bipolar disorders, that directly affect the mental and physical health those who suffer from them, with an incidence is increasing worldwide. Most NDs result complex interaction multiple genes environmental factors such as stress traumatic events, recent Coronavirus Disease (COVID-19) pandemic. In addition to clinical presentations, these diseases heterogeneous in their pathogenesis, brain regions affected, symptoms, making diagnosis difficult. Therefore, finding new biomarkers essential for detection, prognosis, response prediction, development treatments NDs. Among most promising candidates apolipoprotein D (Apo D), component lipoproteins implicated lipid metabolism. Evidence suggests increase Apo expression association aging presence neuropathological processes. As part cellular neuroprotective defense machinery against oxidative inflammation, changes levels have been demonstrated neuropsychiatric conditions like (SZ) (BPD), not only some areas but corporal fluids, i.e., blood serum patients. What clear whether variation quantity could be used indicator detect progression. This review aims provide updated view potential possible biomarker

Journal of Alzheimer s Disease, Год журнала: 2023, Номер 97(2), С. 621 - 633

Опубликована: Дек. 22, 2023

Background: Although cerebrospinal fluid (CSF) amyloid-β42 peptide (Aβ42) and phosphorylated tau (p-tau) blood p-tau are valuable for differential diagnosis of Alzheimer’s disease (AD) from cognitively normal (CN) there is a lack validated biomarkers mild cognitive impairment (MCI). Objective: This study sought to determine how plasma CSF protein markers compared in the characterization MCI AD status. Methods: cohort included Disease Neuroimaging Initiative (ADNI) participants who had baseline levels 75 proteins measured commonly (257 total, 46 CN, 143 MCI, 68 AD). Logistic regression, least absolute shrinkage selection operator (LASSO) Random Forest (RF) methods were used identify candidates classification. Results: We observed that six panel (APOE, AMBP, C3, IL16, IGFBP2, APOD) outperformed seven (VEGFA, HGF, PRL, FABP3, FGF4, CD40, RETN) as well (CSF Aβ42) distinguish [area under curve (AUC) = 0.75 (plasma proteins), AUC 0.60 proteins) 0.56 Aβ42)]. Also, these performed better than line with Aβ42 differentiating CN versus subjects [AUC 0.89 0.85 These results adjusted age, sex, education, APOE ϵ4 genotype. Conclusions: suggests combination 6 can serve an effective marker CN.

Abstract Endometriosis is a common cause of endometrial-type mucosa outside the uterine cavity with symptoms such as painful periods, chronic pelvic pain, pain intercourse and infertility. However, early diagnosis endometriosis still restricted. The purpose this investigation to identify validate key biomarkers endometriosis. Next generation sequencing (NGS) dataset GSE243039 was obtained from Gene Expression Omnibus (GEO) database, differentially expressed genes (DEGs) between normal control samples were identified. After screening DEGs, gene ontology (GO) REACTOME pathway enrichment analyses performed. Furthermore, protein-protein interaction (PPI) network constructed modules analysed using Human Integrated Protein-Protein Interaction rEference (HIPIE) database Cytoscape software, hub Subsequantely, miRNAs genes, TFss miRNet NetworkAnalyst tool, possible TFs predicted. Finally, receiver operating characteristic curve (ROC) analysis used genes. A total 958 including 479 up regulated down screened samples. GO DEGs showed that they mainly involved in multicellular organismal process, developmental signaling by GPCR muscle contraction. Further PPI identified 10 VCAM1, SNCA, PRKCB, ADRB2, FOXQ1, MDFI, ACTBL2, PRKD1, DAPK1 ACTC1. Possible target miRNAs, hsa-mir-3143 hsa-mir-2110, TFs, TCF3 CLOCK, predicted constructing miRNA-hub regulatory TF-hub network. This bioinformatics techniques explore potential novel biomarkers. These might provide new ideas methods for diagnosis, treatment, monitoring

End-stage heart failure (ESHF) leads to hypoperfusion and edema formation throughout the body is accompanied by neurohormonal immunological alterations. Orthotopic transplantation (HTX) has been used as a beneficial option for ESHF. Due shortage of donor hearts, ideal matching timing donors recipients become more important. In this study, our aim was explore relationship between clinical outcomes HTX cytokine apolipoprotein profiles recipient pericardial fluid obtained at after opening sac. The data interleukin, adipokine, lipoprotein levels in twenty were investigated. Outcome variables included primer graft dysfunction (PGD), need post-transplantation mechanical cardiac support (MCS), International Society Heart Lung Transplantation grade ≥2R rejection, mortality.

Опубликована: Май 31, 2024

Gastric cancer (GC) is one of the most prevalent types globally, often detected at advanced stages. However, its prognosis remains poor, necessitating exploration new biomarkers. Disulfidptosis, a recently identified form programmed cell death, has not yet been investigated in relation to GC and associated mechanisms. We analyzed potential associations between disulfidptosis genes clinical risk using TCGA (The Cancer Genome Atlas)-STAD (stomach adenocarcinoma) as training set GSE84433 validation set. In addition, we explored prognostic value biological mechanisms disulfide by consensus clustering, enrichment analysis, mutation histology analysis immune infiltration analysis. Finally, constructed disulfidptosis-related signature (DRRS) assess association class, survival prognosis, infiltration. By utilizing data from 19 genes, successfully subgroups C1 C2 patients through clustering. Notably, 2 groups exhibited significant variations terms rates, scores, Subsequently, developed DRRS via LASSO (least absolute shrinkage selection operator) regression incorporating PRICKLE1, NRP1, APOD, MISP3, SERPINE1. This scoring system effectively distinguished individuals with high low risks, verified These findings strongly indicate close microenvironment tumors. Moreover, demonstrated commendable predictive capabilities for outcomes patients. this study, have different subtypes alterations immunotumour microenvironment. Furthermore, accuracy DRRS, valuable tool predicting survival, function, GC. contribute better comprehension offer opportunities innovative approaches treatment.

Purpose Obesity is associated with an increased risk of aortic diseases and operative risks. Currently, there are no effective drugs available to prevent the occurrence progression aneurysms or dissections. We investigated potential biomarkers therapeutic targets using a multi-omics approach. Methods Clinical data from 117 patients disease were analyzed based on body mass index (BMI) explore relationship between BMI clinical outcomes. An obesity mouse model was developed by feeding high-cholesterol, high-fat diet (HCHFD), established administering human angiotensin II (AngII) at dose 1 mg/kg/day through osmotic minipumps. Through analysis murine transcriptomics serum proteomics, we identified for in obesity. Enzyme-linked immunosorbent assay used detect these serum. Results The duration hospitalization post-surgery positively correlated BMI. Transcriptomic revealed enrichment genes related complement coagulation cascades, as well prion pathway. Proteomic showed proteins African trypanosomiasis estrogen signaling By integrating transcriptomic protein profiles, C5 apoD adverse effects Conclusion High disease, especially dissection. Serum assessing obese individuals. Further research needed pathophysiological pathways linked their applications.
