Despite therapeutic advances, atherosclerosis remains a major global health challenge. Most current treatments target systemic risk factors rather than the diseased vascular wall. Our previous work identified genistein, a soy isoflavone, as a cannabinoid receptor 1 (CB1) antagonist capable of suppressing CB1-mediated vascular inflammation and atherosclerosis. However, its poor water solubility and low oral bioavailability limit clinical application. We aimed to develop water-soluble, orally bioavailable CB1 antagonists for atherosclerosis and to investigate the role of endothelial CB1 in hemodynamic regulation. RNA-sequencing datasets from the NCBI GEO repository were analyzed to assess CB1 expression in atherosclerotic patients. Apolipoprotein E-deficient (Apoe We found CB1 was upregulated in atherosclerotic lesions from patients and mice, and in endothelial cells exposed to disturbed flow. Mechanistically, this was driven by ZNF610 and Spi1 binding and KLF4 dissociation at the CB1 promoter. Daidzein, a soy isoflavone structurally similar to genistein, was identified as a novel CB1 antagonist. To enhance solubility and bioavailability, we developed genistein 7-O-phosphate (G7P) and daidzein 7-O-phosphate (D7P). Pharmacological treatment with these isoflavone monophosphates or genetic CB1 ablation reversed disturbed flow-induced endothelial dysfunction and endothelial-to-mesenchymal transition (EndMT). Oral administration of G7P and D7P significantly reduced atherosclerotic plaque formation in mice. This is the first study to identify transcriptional regulators that drive endothelial CB1 upregulation in response to disturbed flow. We further demonstrated that isoflavone monophosphates ameliorate disturbed flow-induced endothelial dysfunction and EndMT via CB1 inhibition, offering promising oral therapeutics for atherosclerosis.

The apolipoprotein E ε4 (APOE ε4) allele is a major genetic risk factor for Alzheimer's disease, but its relevance to cognition in intracranial atherosclerosis (ICAS) remains unclear. We investigated the association between APOE ε4 and cognition in ICAS. Baseline data from a multicenter cohort were analyzed. Patients with radiologically confirmed ICAS underwent APOE genotyping, plasma biomarker assays, magnetic resonance imaging assessment of cerebral small vessel disease (CSVD) and brain atrophy, and standardized cognitive testing. Among 409 patients (mean age 60 years, 55% male), 16% carried APOE ε4. Carriers showed more frequent cognitive impairment (63% vs 48%), greater stenosis burden, and lower plasma amyloid beta (Aβ)42/40 ratios, whereas other Alzheimer's biomarkers, CSVD burden, and atrophy scores showed no difference. After adjustment, APOE ε4remained associated with cognitive impairment (odds ratio [OR] 1.86). The association was pronounced in women (OR 4.43) but absent in men. APOE ε4 is linked to cognitive impairment in ICAS, particularly in women, through mechanisms beyond Alzheimer's pathology. In patients with ICAS, cognitive impairment was more prevalent in carriers than in non-carriers. Carriers showed greater stenosis burden and lower plasma Aβ42/40 ratios. After full adjustment (stroke, CSVD, and AD biomarkers), APOE ε4 remained associated with cognitive impairment. Female carriers had substantially higher odds of cognitive impairment. Show less

Sodium perfluorononenoxybenzene sulfonate (OBS), a substitute for perfluorooctane sulfonate (PFOS), has been frequently detected in the environment and human blood. Although OBS exposure has been identified as a novel risk factor for atherosclerosis associated with endothelial dysfunction, the underlying molecular mechanisms remain unclear. In this study, in vitro experiments using human umbilical vein endothelial cells (HUVECs) demonstrated that OBS exposure induced oxidative stress, activated the PERK-eIF2α-ATF4 axis of endoplasmic reticulum stress (ERS) and triggered NF-κB signaling. Pharmacological inhibition with N-acetylcysteine (NAC, an antioxidant), 4-phenylbutyric acid (4-PBA, an ERS inhibitor), and BAY 11-7082 (an inhibitor for NF-κB signaling pathway) revealed a sequential pathogenic cascade, in which oxidative stress acts upstream to initiate ERS and compromise endothelial barrier function, leading to NF-κB activation, which drives inflammatory responses, monocyte adhesion, and impaired endothelial migration. Consistent with these findings, in vivo experiments in ApoE Show less

Elevated lipoprotein(a) [Lp(a)] is a genetically determined and independent risk factor for atherosclerotic cardiovascular disease (ASCVD) that is largely resistant to conventional lipid-lowering therapies. Novel Lp(a)-targeted agents, including small interfering RNA (siRNA), antisense oligonucleotides (ASO), and the oral small-molecule inhibitor muvalaplin, have shown potent efficacy in early trials. We conducted a systematic review and network meta-analysis to comprehensively compare their efficacy and safety. A total of 25 randomized controlled trials (RCTs) involving 7715 participants were included, evaluating six siRNA agents, four ASO agents, and one small-molecule inhibitor. The primary outcome was percentage change from baseline in Lp(a). Secondary outcomes included absolute change in Lp(a), percentage changes in apolipoprotein B (apoB) and low-density lipoprotein cholesterol (LDL-C), and adverse events. SiRNA therapies achieved the greatest Lp(a) reductions (olpasiran: mean difference [MD] -92.1%, 95% CI -100.1 to -84.0%; zerlasiran: -80.6%, 95% CI -87.7 to -73.5%), followed by muvalaplin (-76.8%, 95% CI -90.3 to -63.2%) and ASO therapy (pelacarsen: -54.2%, 95% CI -72.2 to -36.2%; all P < 0.001). Most agents achieved absolute Lp(a) reductions exceeding 105 nmol/L, suggesting clinically meaningful benefit. Baseline Lp(a) levels significantly modified treatment response (P < 0.001), and concomitant proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor use further enhanced LDL-C reduction (P = 0.024). All therapies were well tolerated, with injection-site reactions most frequent for injectables, while muvalaplin was well tolerated. These findings indicate that targeted Lp(a)-lowering therapies substantially reduce circulating Lp(a), with siRNA showing the greatest potency and muvalaplin offering a convenient oral alternative for personalized ASCVD risk reduction.

Depression and anxiety disorders are highly comorbid, yet their complex pathogenesis often limits the efficacy of monotherapy. Growing evidence implicates neuroinflammation in their pathogenesis. Co-drugs that linked two active molecules into a single compound and released the drugs after administration, which offering improved efficacy and tolerability than individual drug mixtures or monotherapy. In this work, five new co-drugs ODV-NSAIDs were synthesized from O-desmethylvenlafaxine (ODV) with non-steroidal anti-inflammatory drugs (NSAIDs) to achieve synergistic antidepression and anxiolytic effects. In vitro stability studies exhibited that these co-drugs can be metabolized into two single drugs within 60 min in simulated intestinal fluid. In both acute and chronic LPS-induced models, co-drug ODV-NAP significantly ameliorated depressive-like behaviors, evidenced by increased sucrose preference, reduced immobility in the tail suspension test (TST) and forced swim test (FST), and enhanced locomotion in the open field test (OFT). Furthermore, ODV-NAP decreased brain levels of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and malondialdehyde (MDA), while elevating serotonin (5-HT), norepinephrine (NE), and superoxide dismutase (SOD) activity. Nissl staining confirmed ODV-NAP significantly attenuated hippocampal neuronal damage. Moreover, western blotting revealed ODV-NAP inhibited the TLR4/NF-κB signaling pathway and upregulated BDNF and p-TrkB protein expression. ODV-NAP also inhibited LPS-induced p65 nuclear translocation in BV-2 microglia in vitro, and caused no toxicity in histology. Thus, co-drug ODV-NAP represented a promising novel candidate for treating depression and anxiety. Show less

Precise identification of vulnerable plaque (VAP) is essential for the prevention of acute cardiovascular diseases, yet current molecular probes are hampered by poor VAP lesion penetration and high background. Here, the innate tropism of circulating inflammatory monocytes for VAP, and their differentiation-driven expression of legumain (Lgmn) in response to the VAP microenvironment is exploited. A monocyte differentiation-activated fluorescent (MDAF) probe is conceived that hitchhikes monocytes to precisely migrate to VAP and is activated by Lgmn during monocyte differentiation. This activation triggers in situ self-assembly, resulting in spatiotemporally controlled aggregation-induced emission (AIE) fluorescence signals, and turning the monocyte itself into an on-site "scout" that reports plaque instability.

The large-scale development of pig farming has introduced significant stressors that negatively affect pigs' mental health, behavior, and production efficiency. The hippocampus, crucial for cognition and stress response regulation, plays a central role in these processes. However, the regulatory mechanisms underlying hippocampal function across pig breeds with different domestication statuses and their implications for behavior and breeding strategies remain unclear. We performed single-nucleus RNA sequencing (snRNA-seq) on hippocampal tissues from 22,342 cells across three pig breeds: Asian wild boar, Jinhua, and Duroc, representing different domestication statuses. We identified six major hippocampal cell types and annotated 108 breed-specific transcription factors, including GATA2, SPI1, and EBF1. Additionally, we characterized 83 co-expression modules and 50 significant ligand-receptor pairs, such as TGFβ, WNT, and SPP1, revealing complex intercellular communication networks. Oligodendrocyte expression patterns were conserved across all breeds. We identified 194 candidate genes linked to stress resilience, mental health, and feeding behavior, including MC4R, RYR2, PDE10A, and ABCG2. Alzheimer's disease-related gene enrichment was lower in Duroc pigs, consistent with reduced APOE expression. We also developed the Pig Hippocampus Single-cell Atlas (PHiSA, http://alphaindex.zju.edu.cn:8503/ ), an open-access database allowing breed-specific hippocampal analyses and validation of gene expression at the single-nucleus level. This study offers insights into hippocampal function regulation in pigs, focusing on stress resilience, behavior, and productivity. It highlights conserved and breed-specific molecular features of hippocampal cell types and their roles in adaptability and mental health. By integrating single-nucleus data, the research suggests that genetic strategies could be used to improve animal welfare, stress management, and production efficiency in pig breeding programs.

This study aimed to assess the knowledge, attitudes, and practices (KAP) of patients with lower limb arteriosclerosis obliterans (ASO) toward their disease. This cross-sectional study was conducted at 3 tertiary hospitals in Chengdu between August 2023 and January 2024 and included patients with lower limb ASO. Data were collected using an interviewer-administered questionnaire that captured demographic information and KAP scores. A latent profile analysis (LPA) was used to identify the KAP patterns among participants. A total of 515 nonproblematic questionnaires were collected, yielding an effective response rate of 95.72%. Among the respondents, 395 (76.85%) were male, with a disease course of 15.96 ± 17.55 months. The knowledge, attitude, and practice scores were 5.27 ± 4.69 (possible range: 0-22), 17.65 ± 2.86 (possible range: 5-25), and 107.63 ± 17.15 (possible range: 33-165), respectively. LPA identified 4 participant profiles: Profile 1 (high attitude, low practice), Profile 2 (low attitude, high practice), Profile 3 (low attitude, low practice), and Profile 4 (high attitude, high practice). Significant differences were found among profiles in residence (P = 0.028), medical insurance (P = 0.043), self-efficacy (P < 0.001), and patient activation (P < 0.001). Patients with lower limb ASO demonstrated inadequate knowledge but moderate levels of attitude and practice. Residence, medical insurance, self-efficacy, and patient activation may affect the KAP patterns of the patients. These findings suggest that tailored interventions targeting distinct patient profiles, while considering broader social determinants of health, may be critical to improving self-management and outcomes.

Nasopharyngeal carcinoma (NPC) is a complicated pathological cancer, which has a close association with pyroptosis and abnormal alternative splicing (AS). However, the molecular changes and functions of AS-mediated pyroptosis in cisplatin-resistant NPC cells remain poorly understood. The expression patterns of different splicing isomers of dual-specificity phosphatase 6 (DUSP6) were evaluated by semi-quantitative PCR. The effects of DUSP6 knockdown on cisplatin sensitivity and pyroptosis in NPC were examined by CCK-8 assay, immunofluorescence and ELISA. The occurrence mechanism of DUSP6 AS was explored by RNA pull down, mass spectrometry and MeRIP-PCR. DUSP6 underwent AS, among which the intron retention isoform DUSp6-IR1 increased in expression dependent on the dose and time of cisplatin. Knockdown of DUSP6-IR1 significantly suppressed viability and cisplatin resistance and promoted apoptosis of C666-1 cells upon cisplatin treatment. In vivo, sh-DUSP6-IR1 reduced the weight and volume of tumors. While DUSP6-IR1 knockdown in C666-1 cells enhanced pyroptosis (evidenced by elevated LDH release, Gasdermin D (GSDMD)/NOD-like receptor thermal protein domain associated protein 3 (NLRP3) expression, and IL-18/IL-1β levels, along with reduced cell viability), these effects were reversed by a pyroptosis inhibitor. The m6A reader protein insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) enhanced the splicing generation of the DUSP6-IR1 isoform through its KH3-4 domains, thereby suppressing pyroptosis in NPC cells and ultimately conferring cisplatin resistance. These findings revealed a promising novel direction to investigate cisplatin resistance and suggested potential therapeutic target for overcoming chemotherapy resistance in NPC.

This study used a group-based multi-trajectory model (GBMTM) to identify distinct muscle health trajectories and examine their associations with physical activity (PA) in middle-aged and older adults. Data were obtained from 2818 middle-aged and older adults (aged ≥40 years) in the China Health and Retirement Longitudinal Study (2011-2015). Muscle health was assessed using muscle mass (appendicular skeletal muscle mass index), muscle strength (handgrip strength), and physical performance (5-time chair stand test). PA was assessed using the International Physical Activity Questionnaire Short Form. A GBMTM was applied to jointly identify longitudinal trajectories of muscle mass, muscle strength, and physical performance, and to evaluate their associations with PA. In this study, four muscle health trajectories were identified: low-function declining, moderate-function declining, moderate-function stable, and high-function stable group. Engaging in ≥150 min/wk of light PA (LPA), moderate PA (MPA), or vigorous PA (VPA) was associated with the moderate-function stable group (LPA: aOR = 3.44, 95% CI: 1.94 - 6.11; MPA: aOR = 2.83, 95% CI: 1.67 - 4.96; VPA: aOR = 2.88, 95% CI: 1.61 - 5.13) and the high-function stable group (LPA: aOR = 5.20, 95% CI: 2.44 - 11.19; MPA: aOR = 4.10, 95% CI: 1.92 - 8.73; VPA: aOR = 3.42, 95% CI: 1.55 - 8.55). In older adults aged ≥70 years, associations persisted for MPA and VPA. Distinct muscle health trajectories highlight individualized muscle aging and inform personalized PA guidance. Regular PA ≥150 min/wk across intensities was associated with more favorable longitudinal muscle health. Show less

Obstructive sleep apnea (OSA) is characterized by recurrent intermittent hypoxia (IH) and has been increasingly associated with lung cancer incidence and mortality. However, how IH-related biological programs relate to immune remodeling, stemness-associated phenotypes, and therapeutic resistance in lung cancer remains incompletely understood. We integrated single-cell RNA sequencing data from IH-exposed murine lung tissues (GSE301350) with bulk transcriptomic datasets from TCGA-LUAD and GSE31210 to examine hypoxia-associated cellular and transcriptional patterns. Stemness was quantified using CytoTRACE and transcriptome-based stemness scoring, and its associations with immune infiltration, immune checkpoint expression, TIDE scores, predicted drug sensitivity, and immunotherapy response were evaluated. A stemness-based prognostic model was constructed using LASSO Cox regression and validated in independent cohorts. Single-cell analysis revealed marked immune remodeling under intermittent hypoxia (IH), including expansion of effector T cells, and monocytes/macrophages, populations alongside reduced B cells and dendritic cells. In human LUAD cohorts, stemness-high tumors were associated with mitochondrial and metabolic stress-related transcriptional programs, and increased expression of immune checkpoint genes (PD-1, PD-L1, CTLA4, LAG3). Elevated stemness scores correlated with higher TIDE scores, poorer overall survival, and reduced predicted responsiveness to immunotherapy. LASSO modeling identified a six-gene stemness signature (EIF5A, MELTF, SEMA3C, CPS1, TCN1, SELENOK), that consistently stratified patients into high- and low-risk groups across TCGA and GSE31210 cohorts. Multivariate Cox regression confirmed the risk score as an independent prognostic factor. Drug sensitivity analyses further suggested that stemness-high tumors may exhibit increased susceptibility to selected kinase inhibitors (Dasatinib, A-770041) and metabolic modulators (Phenformin, Salubrinal). OSA-associated IH is linked to stemness-associated transcriptional plasticity, immune suppression, and adverse clinical outcomes in lung cancer. The identified stemness-based gene signature provides a robust prognostic biomarker and highlights potential therapeutic vulnerabilities, supporting integrative strategies that combine stemness and immune -targeted approaches with immunotherapy in OSA-associated lung cancer.

The integrated stress response (ISR) has been implicated in cognitive decline associated with ageing and neurodegenerative diseases. Pharmacological inhibition of the ISR using the small-molecule ISRIB has demonstrated promising neuroprotective effects in several preclinical models. However, its potential therapeutic value in vascular cognitive impairment (VCI) remains largely unexplored. Here, we established a modified permanent bilateral carotid occlusion (2-VO) rat model of VCI and investigated the therapeutic potential of the ISRIB via microinjection in hippocampal dentate gyrus (DG). VCI rats exhibited elevated expression of vascular endothelial growth factor (VEGF), cluster of differentiation 34 (CD34), ionized calcium-binding adapter molecule 1 (Iba1), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6), indicating successful establishment of the model. Behavioral assessments revealed that VCI rats exhibited impaired spatial, working, and recognition memory. Bioinformatic analysis highlighted ISR pathway activation in VCI. Furthermore, elevated phosphorylated eukaryotic initiation factor 2 alpha (p-eIF2α) and activating transcription factor 4 (ATF4) protein levels in the DG confirmed ISR activation in the DG of VCI rats. VCI also reduced neuronal integrity, as evidenced by decreased Nissl body density. ISRIB treatment significantly improved cognitive performance, suppressed ATF4 expression, enhanced puromycin-labeled protein synthesis, and restored phosphorylated cAMP response element-binding protein (p-CREB) and brain-derived neurotrophic factor (BDNF) signaling. Notably, ISRIB increased c-fos activation and upregulated synaptophysin and postsynaptic density protein 95 (PSD95) expression in the DG of VCI rats, indicating enhanced neuronal activity and synaptic function. Our results indicate that ISR activation contributes to hippocampal-dependent memory impairment in VCI. ISRIB effectively restores synaptic function and cognition, underscoring its therapeutic value and translational potential in treating VCI. Show less

While mindfulness has demonstrated efficacy in enhancing executive function in non-athletes through improved present-moment awareness and acceptance of current experiences, particularly regarding attention regulation and cognitive control, its neurocognitive mechanisms and the effects and underlying mechanisms of mindfulness-based intervention (MBI) on different executive functioning skills in athletic populations remain poorly understood. The purpose of this randomized controlled trial tackles a novel and important topic by investigating the beneficial effects of 12-week MBI on executive functioning skills in baseball players-a population that faces unique cognitive and physical demands, and the associated neurophysiological and biochemical regulation mechanisms. Thirty-four baseball players were randomly divided into the MBI group (11M/6F) and the control group (11M/6F). Executive functioning skills (N-back task for working memory, Stroop task for inhibitory control, and Switching task for cognitive flexibility) were tested before and after the intervention. Functional near-infrared spectroscopy (fNIRS) was used to record quantified hemodynamic responses in the prefrontal cortex through oxygenated hemoglobin concentration (Oxy-Hb) monitoring during the performance of executive function tasks. Biomarkers of cognitive function, including BDNF, IL-6, TNF-α, and Cortisol, were measured using enzyme-linked immunosorbent assays (ELISA). MBI partially improved all three executive function skills, with increased Oxy-Hb level in L-FPA during the task of working memory, increased Oxy-Hb level in R-VLPFC during the task of inhibitory control, and decreased Oxy-Hb level in R-FPA, M-FPA, and L-DLPFC during the task of cognitive flexibility. Furthermore, MBI increased circulating BDNF level and decreased IL-6 and Cortisol levels. In addition, our correlation analyses showed that improvement in executive function (improved behavioral performances and changes in Oxy-Hb levels) were associated with changes in Cortisol and inflammatory cytokines (TNF-α and IL-6). A 12-week MBI partially improved three components of executive function in baseball players. This enhancement may be attributed to the MBI-induced reductions in Cortisol and inflammatory cytokines (such as TNF-α and IL-6), which altered blood oxygen contents in specific brain regions, thereby promoting executive function.

Anoikis resistance and epithelial-mesenchymal transition (EMT) are crucial factors in tumor invasiveness and metastasis in lung adenocarcinoma (LUAD). Identifying anoikis-EMT-related genes could be beneficial for predicting prognosis and immunotherapeutic efficacy in patients with LUAD. This study aims to establish and validate a novel prognostic signature based on anoikis-EMT-related genes for LUAD and to identify the potential biomarkers encapsulated within it. Anoikis-related genes and EMT-related genes were retrieved from the GeneCards and dbEMT 2.0 databases. Univariate Cox regression analysis and principal component analysis (PCA) were conducted to define anoikis and EMT levels. Gene expression and clinical information of patients with LUAD were downloaded from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) databases. Univariate Cox regression and multivariate Cox regression analyses were conducted to construct a risk score model. Immune correlation and drug sensitivity analyses were performed to investigate the association of the risk score with the immune profile and antitumor treatment. Three essential genes in the model were examined for messenger RNA (mRNA) expression by reverse transcription-polymerase chain reaction (RT-PCR) and for protein levels via the Human Protein Atlas (HPA) database. LUAD patients demonstrating low Anoikis Potential Index (API) combined with high EMT Potential Index (EPI) exhibited the poorest overall survival (OS). We further constructed a nine-gene prognostic risk model that combines anoikis and EMT. High-risk patients demonstrated significantly shorter survival duration. The clinical-prognostic nomogram accurately predicted outcomes at 1, 3, and 5 years. In addition, patients in low-risk group demonstrated superior immune responses to treatment and were more sensitive to commonly used chemotherapy drugs. Our validation studies confirmed upregulated expression of ANGPTL4, SLC2A1, and BIRC5 in LUAD, observed at both transcriptional and translational levels. The anoikis-EMT-based risk model effectively forecasts both OS and immunotherapy response in LUAD patients, accelerating the identification of groundbreaking molecular biomarkers and prospective molecular targets.

Excessive fat deposition compromises the health of companion animals and the carcass quality of food-producing livestock. Follicle-stimulating hormone (FSH) has been demonstrated to play a critical regulatory role in fat deposition, with its function dependent on binding to its cognate receptor (FSHR) in target organs. In this study, female Sprague-Dawley (SD) rats were immunized with subunit vaccines targeting FSHβ and FSHR, respectively, and obesity was induced by a high-fat diet (HFD) to investigate the effects of these vaccines on adipose deposition in female mammals. The results revealed that active immunization against FSHβ and FSHR effectively suppressed HFD-induced obesity and the elevated serum triglyceride levels. Histological observations found that FSHβ and FSHR immunity decreased adipocyte hypertrophy and increased the cross-sectional area of skeletal muscle fibers caused by HFD, partially ameliorated HFD-associated hepatic sinusoidal spaces and vacuolated steatosis in the cytoplasm. RT-qPCR results indicated that FSHβ and FSHR immunization inhibited lipid synthesis by downregulating adipogenic-related genes, including C/ebpα, Creb, Pparγ, Lpl, and Perilipin. These findings suggest that both vaccines can mitigate HFD-induced adipose deposition in rats, with the FSHR vaccine exhibiting more pronounced effects. This study provides a novel strategy to mitigate pet health deterioration caused by excessive obesity and the decline in carcass quality of food-producing livestock. Show less

Alzheimer' s disease (AD) is a progressive neurodegenerative disorder characterized by a spectrum of cognitive impairments, ranging from mild memory loss to severe cognitive decline and, ultimately, death. The global incidence of AD is projected to increase significantly, with late-onset AD being predominantly sporadic in nature. Over the past three decades, the Apolipoprotein E (APOE) gene has been recognized as the most important single genetic determinant of sporadic AD risk. The APOE4 allele is a major risk factor for AD and is known to exacerbate the pathological process for AD. Identifying protective variants that may reduce the risk or delay the onset of AD is of great significance for the development of effective treatments. This review comprehensively examines the protective effects of APOE and its related protective mutations. It also explores the impact of these unique protective variants at the cellular level during the pathological progression of AD. Furthermore, the review compiles new insights for AD treatment offered by these protective mutations, exploring the potential applications of APOE and its related protective variants in advanced therapeutic strategies, including gene editing, RNA editing, and stem cell therapy.

The melanocortin-4 receptor (MC4R), a key regulator of energy balance and feeding behavior, plays a critical role in sheep growth. Herein, we identified a naturally occurring conserved functional SNP (g.59480661G > A, E100K, P.Glu100Lys) in the sheep MC4R gene. Using the Kompetitive Allele Specific PCR method, we detected this mutation in 2,151 sheep from six different breeds. Association analysis revealed that this mutation affects the growth traits of Luxi Blackhead sheep, and the individuals with AA (K100) genotype exhibited superior growth performance compared to the GG (E100) genotype. Additionally, whole-genome sequencing data from 49 sheep breeds, totaling 968 individuals, showed a higher mutation frequency of this variant in some large-sized sheep breeds. Functional studies demonstrated that the E100K mutation does not affect protein localization or transport but reduces surface and total protein expression. The mutated receptor exhibited decreased basal activity and reduced binding efficiency with agonists (α-MSH and β-MSH), resulting in a partial loss of function. Transcriptomic analysis indicated that this mutation affects downstream pathways, including osteoclast differentiation and the MAPK signaling pathway, which may influence growth regulation associated with the E100K mutation. Collectively, these findings underscore the substantial role of the partial loss-of-function MC4R E100K mutation in regulating growth traits in sheep. Show less

Maintaining nerve integrity and rescuing/regenerating injured neurons are pivotal for spinal cord injury (SCI) repair. Herein, an immuno-neuroprotectant (INPT) is developed to mitigate secondary SCI and promote neuroregeneration via sequestration of neutrophil extracellular traps (NETs) and targeted delivery of brain-derived neurotrophic factor (BDNF). To construct the INPT, positively charged BDNF is engineered into negatively charged A-BDNF nanoparticles (A-BDNF NPs) via reversible modification with adenosine triphosphate, and A-BDNF NPs are further coated with polySia-overexpressing microglia membrane (PBM). In SCI mice, intravenously injected INPT effectively accumulates in the injured spinal cord and then binds to NETs through the over-expressed polySia on PBM. This binding triggers PBM shedding from the NPs, and thereby, phosphatidylserine localized at the cytoplasmic leaflet of PBM is exposed and displayed on the NETs surface. Consequently, the PBM-bound NETs are cleared by phagocytes via efferocytosis, which provokes neuroprotective immune responses. Meanwhile, the mildly acidic environment triggers traceless restoration of A-BDNF NPs to the native BDNF to foster neuroregeneration. Thus, PBM-mediated NETs sequestration cooperates with BDNF-mediated neuroregeneration to restore neurological recovery. This study provides an enlightened approach for remedying NET-associated pathophysiological aberrations and also renders a facile yet effective platform for biomacromolecule delivery to the central nervous system.

This study aimed to use latent profile analysis (LPA) to identify heterogeneous configurational patterns of short video addiction and emotion dysregulation among college students, and to systematically examine the predictive effects of cognitive reappraisal, emotional loneliness, and sociodemographic factors on latent profile membership. A cross-sectional survey design was employed. From April to July 2025, full-time undergraduate students were recruited from multiple universities in Shandong Province using a combination of convenience sampling and snowball sampling. Participants completed online questionnaires including the Short Video Addiction Scale, the Emotion Dysregulation Inventory (EDI), the Cognitive Reappraisal Scale, and the Emotional Loneliness Scale. A total of 1,168 valid questionnaires were obtained. LPA identified four optimal profiles: Profile 1 ("low short video addiction-low emotion dysregulation"), Profile 2 ("medium to lower short video addiction-medium to lower emotion dysregulation"), Profile 3 ("medium to upper short video addiction-medium to upper emotion dysregulation"), and Profile 4 ("high short video addiction-high emotion dysregulation"). Multivariable logistic regression analyses indicated that, with Profile 4 as the reference category, cognitive reappraisal significantly increased the likelihood of membership in lower-risk profiles, whereas emotional loneliness significantly decreased the likelihood of membership in lower-risk profiles. Among sociodemographic factors, being female and having an urban background significantly increased the likelihood of membership in Profile 1 (vs. Profile 4); being a non-only child and having no part-time work experience significantly predicted membership in Profile 3. Marked heterogeneity exists among college students in the measured dimensions of short-form video addiction and emotion dysregulation, and the two constructs exhibit highly concordant co-variation. The findings provide empirical support for developing risk-stratified and precision-oriented mental health intervention strategies. Show less

Thin endometrium (TE), affecting 1.5 %-9.1 % of reproductive-aged women, emerges as a disturbed decidua microenvironment underpinning implantation failure and recurrent pregnancy loss. Through integrated single-cell transcriptomics with histopathology and multiplex immunofluorescence (TSA) validation, we delineated TE as a disease of coordinated repairment impairment and pro-fibrotic remodeling across stromal and immune compartments. Key findings revealed a pathological imbalance in stromal subsets, including the decrease of regenerative IGFBP3 + Stromal₁ cells and expansion of fibrogenic Stromal₂ populations, driving collagen-dominant extracellular matrix remodeling. Concurrently, immune dysfunction was unmasked. NK cells decreased and shifted from immune surveillance to a pro-inflammatory phenotype, T cells transitioned from immune regulation to extracellular matrix remodeling effectors and macrophages adopted a pro-fibrotic phenotype with lipid metabolic collapse. CellChat analysis pinpointed suppression of GZMA-PARD3 and APOE-TREM2 axes as drivers of stromal dysfunction, while the hyperactivated adhesion (LAMA3) and collagen pathways served as central mediators of the fibro-inflammatory cascade. These findings, based on single-cell RNA-seq and spatial verification, suggest therapeutic targets for restoring endometrial homeostasis in TE. These findings suggested that TE as a disease of progressive stromal-immune fibrosis dysregulation, offering novel therapeutic targets to restore endometrial repairment and microenvironmental homeostasis.

Atherosclerosis is a chronic inflammatory disease marked by lipid accumulation and immune cell infiltration in arterial walls. Macrophages contribute by internalizing oxidized low-density lipoprotein, forming foam cells, and driving inflammation. The ubiquitin-proteasome system regulates immune and inflammatory responses in atherosclerosis. This study investigated the protective role of TRIM31 (tripartite motif-containing 31), an E3 ubiquitin ligase, in macrophage lipid metabolism and inflammation through selective regulation of LOX-1 (lectin-like oxidized low-density lipoprotein receptor-1). Transcriptomic profiling, macrophage-specific TRIM31 was selectively upregulated in macrophages under oxidized low-density lipoprotein stimulation and in atherosclerosis plaques. Trim31 deficiency exacerbated plaque burden, foam cell formation, and inflammatory signaling (n=8 per group). Single-cell analysis revealed enrichment of lipid transport and inflammatory pathways in Trim31-deficient plaques. LOX-1 was identified as a key TRIM31 substrate. TRIM31 promoted K48-linked ubiquitination of LOX-1 at lysine 12, facilitating its degradation. The atheroprotective effects of Trim31 were abolished in TRIM31, an inducible, macrophage-enriched protective factor in atherosclerosis, restricts foam cell formation and inflammation by targeting LOX-1 for proteasomal degradation. These findings position TRIM31 as a promising therapeutic target for macrophage-driven atherogenesis. Show less

Staphylococcus aureus is a significant pathogen that poses a threat to both human and animal health. Its pathogenicity in humans has been extensively studied, however, the signaling pathways and key genes in Koi Carp responding to S. aureus from human rhinitis remain unclear. In this study, we established an intraperitoneal infection model in koi carp (Cyprinus carpio) using an S. aureus isolate from patients with rhinitis and integrated RNA-seq, qPCR, and ELISA to dissect the host response. Our findings reveal a dual-module immune evasion strategy employed by S. aureus in koi carp. Module I: The pathogen down-regulated the entire complement coagulation cascade (C3, C9, CFH, F7/9/10) and apolipoprotein-mediated opsonins (APOA1, APOB, APOC1/2), thereby crippling innate clearance. Module II: The host mounted a restricted but potent counter-response, characterized by type I IFN signalling (gvin1, MHC-I), NK/T-cell co-stimulation (CD244, SLAMF5), and the selective induction of IL-8 and IL-1β, while IL-6, IL-10, and TNF-α remained unchanged. Functionally, serum superoxide dismutase (SOD), catalase (CAT), and lysozyme (LZM) activities surged, confirming an oxidative burst, whereas splenic CD22R protein decreased, indicating B-cell disinhibition. These results establish a molecular basis for understanding the interaction between human-derived S. aureus and the immune system of aquatic organisms. Show less

N-carbamylglutamate (NCG) is an activator of arginine biosynthesis, but its specific role in crustaceans remains poorly understood. This study aimed to investigate the effects of NCG on arginine biosynthesis capacity, metabolism, digestion, and the gene expression of the mTOR signaling pathway in Eriocheir sinensis. In Experiment 1, hepatopancreas was cultured in vitro with NCG medium (0, 65, 75, and 85 mg/L NCG). In Experiment 2, crabs were fed either regular feed or NCG feed (content: 302.96 ± 4.07 mg/kg) for 14 days. In Experiment 1, NCG significantly upregulated pyrroline-5-carboxylate synthase (p5cs) gene expression (P < 0.05), an enzyme that is related to arginine biosynthesis. Similarly, dietary NCG upregulated p5cs expression and significantly increased the activities of carbamoyl-phosphate synthase-1 (CPS-1) and P5CS in the hepatopancreas and intestine (P < 0.05). Metabolomics analysis indicated that NCG altered the metabolic profile of the hepatopancreas, promoting cholesterol metabolism, and arginine and proline metabolism. In the intestine, trypsin and α-amylase activities were significantly elevated (P < 0.05). NCG also altered the composition of intestinal microflora, with an increase in Proteobacteria and in the ratio of Firmicutes to Bacteroidota. Additionally, NCG increased the content of signaling molecule nitric oxide (NO) and upregulated the expression of genes in the mTOR signaling pathway (P < 0.05). In conclusion, NCG supplementation enhanced arginine biosynthesis capacity, stimulated intestinal enzymatic activities, and upregulated mTOR signaling pathway gene expression in Eriocheir sinensis, indicating the potential for improved metabolism and digestion.

Visceral pain is frequently accompanied by depression, a comorbidity involving central neuroinflammation and abnormal neuronal plasticity. The P2X7 receptor (P2X7R) plays a crucial role in neuroinflammation and pyroptosis, while Jujuboside A (JuA), a major saponin extracted from Ziziphus jujuba seeds, has been reported to exert significant antidepressant and analgesic effects. In this study, we systematically evaluated the regulatory effects of JuA on the P2X7R-brain-derived neurotrophic factor (BDNF) pathway and on pyroptosis and apoptosis using a rat model of colorectal distension (CRD) and primary neuron/astrocyte cultures. JuA markedly alleviated visceral hypersensitivity and depressive-like behaviors in CRD rats and reduced P2X7R expression in both the spinal cord (SC) and hippocampus (HPC). Further investigations in vitro revealed that JuA inhibited excessive P2X7R activation in SC astrocytes, thereby decreasing the expression of NLRP3, Caspase-1, GSDMD, IL-1β and TNF-α, indicating suppression of pyroptosis. Similarly, JuA exerted an anti-pyroptotic effect in HPC astrocytes and inhibited neuronal apoptosis by reducing Caspase-3 and Bax levels while increasing Bcl2 expression, leading to upregulation of HPC BDNF. Collectively, JuA targets P2X7R and suppresses downstream pyroptotic and apoptotic signaling in vitro, which may contribute to its neuroprotective effects. These findings provide experimental evidence supporting the potential of JuA as a therapeutic agent for comorbid visceral pain and depression. Show less
