Atherosclerotic lesions commonly develop in curved or bifurcated arteries, where blood flow exhibits characteristics of low shear stress (LSS). Subjected to LSS continually, endothelial cells (ECs) adopt a pro-atherosclerotic phenotype. Ferroptosis is a recently identified form of controlled cell demise prompted by iron-dependent buildup of cellular reactive oxygen species (ROS), which has been associated with diverse cardiovascular diseases, particularly atherosclerosis (AS). P53 is a broadly acting tumor suppressor that can be activated by diverse stimuli and mediates multiple biological outcomes, including cell cycle arrest, DNA repair, apoptosis, and ferroptosis. However, it remains unknown whether LSS promotes the development of AS by inducing P53-dependent ferroptosis in endothelial cells. In our experiments, we induced LSS by partial ligation of the right common carotid artery in high-fat diet-fed (HFD) male ApoE Our findings demonstrated that LSS induced endothelial ferroptosis, which in turn accelerated AS development both in vivo and in vitro. This effect was partially counteracted by both the ferroptosis inhibitor Fer-1 and endothelium-specific glutathione peroxidase 4 (GPX4) overexpression in ApoE Our experiments suggested that LSS promotes atherosclerosis by inducing endothelial ferroptosis through the P53/xCT signaling pathway.

Hemodynamic abnormalities within atherosclerotic plaque regions, particularly localized high shear stress and endothelial dysfunction, present novel targets for intervention by drug delivery systems. In this study, we designed a polysaccharide-based carrier (HF-AF) from fucoidan, featuring a dynamic supramolecular structure. A dynamic supramolecular network was established within this carrier via dynamic supramolecular interactions between hydroxypropyl-β-cyclodextrin and adamantane-methylamine. The anti-inflammatory compound tilianin, formulated into nanocrystals (Til NCs), was then encapsulated to create a shear-responsive nanosystem (HF-AF@Til NCs). The system's primary therapeutic strategy is its response to pathological hemodynamic forces: upon encountering high shear stress at a stenosis, the supramolecular network undergoes dissociation, triggering a mechanically-gated release of the encapsulated Til NCs. This shear-triggered function is complemented by the natural P-selectin affinity of the fucoidan backbone, which facilitates the anchoring of the nanocarrier at the inflamed lesion site. This sophisticated "anchor-and-release" mechanism enables superior drug accumulation precisely at plaque sites. In ApoE Show less

Insomnia and anxiety are highly comorbid, severely compromising quality of life. Efficacy of current pharmacological interventions for this dual condition remains limited. Zhi-Gan Formula (ZG), consisting of Zhi-Zi-Chi Decoction and Ganmai Dazao Decoction, two classic Traditional Chinese Medicine (TCM) formulae clinically widely used for insomnia or anxiety, holds promise as a therapeutic option for insomnia-anxiety comorbidity. This study aimed to assess ZG's sleep-promoting and anxiolytic efficacy, and investigate the novel mechanism through which pituitary adenylate cyclase-activating polypeptide (PACAP) in the medial prefrontal cortex (mPFC) modulates comorbid sleep and anxiety conditions. Mice received 4-chloro-DL-phenylalanine (PCPA) injections and were subsequently administered ZG or diazepam. Behaviors were assessed using the pentobarbital-induced sleep test, open-field test (OFT), and elevated plus-maze test (EPM). Key pathways were identified via network pharmacology analysis and validated using long-term potentiation (LTP) recordings and protein quantification. Viral-mediated PACAP knockdown vectors were transfected into the mPFC. PCPA administration induced insomnia and anxiety-like behaviors. ZG administered for 3 days significantly shortened sleep latency, prolonged sleep duration, and alleviated anxiety-like behaviors, whereas diazepam only partially improved anxiety-like behaviors. Network pharmacology analysis suggested ZG's engagement in neuropeptide-receptor interactions and synaptic transmission pathways. Assessments of synaptic plasticity showed that ZG improved mPFC LTP and the expression of synaptic proteins (PSD95, synapsin-1, BDNF) impaired in the model mice. Moreover, the expression of the neuropeptide PACAP and downstream eEF2 signaling for synaptic protein synthesis were all improved by ZG. Crucially, perfusion of a PACAP agonist in the mPFC brain slices from sleep-deprived mice rescued LTP deficits. Finally, mPFC PACAP knockdown abolished the therapeutic effects and the enhanced expressions of the synaptic proteins by ZG. ZG alleviated insomnia-anxiety comorbidity by restoring synaptic plasticity in the mPFC via the PACAP-eEF2-BDNF pathway, which may also shed light on the development of a novel therapeutic approach for the treatment of sleep-anxiety comorbidity.

Fusion genes are pivotal drivers of tumorigenesis, often generating oncogenic chimeric RNAs and fusion circular RNAs. However, the mechanisms by which these transcripts synergistically contribute to cancer progression remain poorly understood. Here, we identified a lung cancer-specific chimeric RNA KANSL1-ARL17A (chKANSARL) and its circular variant fusion circular RNA KANSL1-ARL17 A (F-circKA), both derived from the fusion gene KANSARL. Functional assays revealed that overexpression of either chKANSARL or F-circKA significantly enhanced lung cancer cell proliferation, migration, and invasion, while their knockdown suppressed these malignant phenotypes. In vivo experiments demonstrated that chKANSARL overexpression accelerated tumor growth in immunodeficient mice. Notably, coexpression experiments uncovered a synergistic regulatory interaction between F-circKA and chKANSARL, amplifying oncogenic effects. Mechanistically, miRNA sequencing and dual-luciferase assays revealed that F-circKA acts as a molecular sponge for miR-6860, thereby derepressing chKANSARL expression. Rescue experiments further validated this regulatory axis, wherein miR-6860 inhibition reversed the tumor-suppressive effects of F-circKA knockdown. Collectively, our study identifies and characterizes a novel F-circKA/miR-6860/chKANSARL regulatory axis, revealing how dual transcriptional outputs from the KANSARL fusion gene can synergistically drive lung cancer progression. These findings highlight a previously unrecognized layer of cooperative regulation between linear and circular fusion RNAs in oncogenesis and provide a new framework for understanding fusion gene-mediated tumorigenesis.

Individuals with prediabetes or diabetes face elevated dementia risk, yet robust prediction tools and mechanistic insights remain limited. This study aimed to develop and validate a protein-based risk score for dementia prediction in this high-risk population while elucidating underlying biological pathways and therapeutic targets. Utilising data from 10 433 UK Biobank participants with prediabetes or diabetes and proteomic profiling (2911 plasma proteins measured), we developed a dementia protein risk score in a training set ( In the training set, 23 out of 2911 proteins were selected. In the testing set, compared with the basic model (age and sex, C-index: 0.78; 95% confidence interval [CI] 0.74-0.82), the dementia protein risk score (C-index: 0.84; 95% CI 0.81-0.88) significantly improved the performance in predicting incident dementia (C-index increase: 0.06; 95% CI 0.02-0.12), while cardiovascular risk factors, ageing and dementia incidence risk factors (C-index: 0.80; 95% CI 0.76-0.83) and apolipoprotein E (APOE; age and sex included, C-index: 0.81; 95% CI 0.77-0.85) had no significant improvement. Six key proteins (glial fibrillary acidic protein [GFAP], neurofilament light polypeptide [NEFL], Brevican core protein [BCAN], protein MENT [MENT], APOE and growth/differentiation factor 15 [GDF15]) captured the most predictive power. Pathway analyses implicated extracellular matrix remodelling and cholesterol metabolism, whereas Mendelian randomisation identified causal roles for APOE, haematopoietic prostaglandin D synthase (HPGDS), BAG family molecular chaperone regulator 3 (BAG3) and GDF15. Nine proteins were prioritised as druggable targets, including HPGDS, with existing Food and Drug Administration-approved drugs. This study establishes a highly accurate protein-based risk score for dementia prediction (including 6-23 proteins) in individuals with prediabetes or diabetes, uncovering actionable biological pathways and therapeutic targets. The findings enable precision risk stratification and accelerate translational opportunities for dementia prevention in this population. Show less

Near-infrared (NIR)-II fluorescence imaging at 1000-1700 nm is widely used for deep-tissue visualisation and disease theranostics in the brain, with NIR-II theranostics greatly improving imaging resolution, imaging depth, and therapeutic efficacy. However, the extreme lack of molecular design in NIR-II fluorophores has slowed the discovery of bright candidates and restricted their efficacious application in brain theranostics. Here, we develop a covalent bond locking (CBL) strategy that enables the feasible design of bright NIR-II fluorophores by effectively restricting the twisted intramolecular charge transfer state. These spirofluorophores incorporate terminally spiro-donor groups, which leads to a higher molar extinction coefficient and improved quantum yield than non-spirofluorophores do. With bright and stable NIR-II fluorescence advantages, we demonstrate that CBL nanoparticles (NPs) of spirofluorophores achieve multiscale high-resolution NIR-II angiography via one-photon fluorescence and two-photon fluorescence bioimaging simultaneously. With apolipoprotein E (ApoE) modification, CBL@ApoE NPs achieve enhanced blood-brain barrier permeability, facilitating superior brain glioma theranostics. This work proposes a CBL strategy to engineer highly bright NIR-II fluorescent fluorophores, providing a reliable nanoplatform for deep brain theranostics that can be effectively delivered across biological barriers to target brain tumors.

This study evaluates plasma-based proteomic profiles for predicting amyloid positivity in adults with Down syndrome (DS) and examines the impact of apolipoprotein E ε4 (APOE ε4) on test performance. Cross-sectional data from 290 adults with DS were analyzed using single molecule array (SIMOA) technology to measure plasma amyloid beta (Aβ)42, Aβ40, neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), tau phosphorylated at threonine 181, and total tau. Amyloid burden was quantified using Pittsburgh Compound B and (18)F-florbetapir Aβ positron emission tomography. Support vector machine analyses were conducted with biomarkers as predictors and age, sex, and APOE ε4 carrier status as covariates. Age, GFAP, and NfL contributed the most to the model performance. The proteomic profile achieved an area under the curve (AUC) of 96% in models with and without APOE ε4. These findings suggest that plasma proteomic biomarkers can effectively identify amyloid positivity in adults with DS and may support clinical triage, monitoring, and selection for clinical trials, independent of APOE ε4 status.

Atherosclerosis is a chronic and progressive inflammatory disease that can lead to adverse cardiovascular and cerebrovascular events. Phenotypic switching of vascular smooth muscle cells (VSMCs) plays a pivotal role in its development and progression, but the upstream regulatory mechanisms remain incompletely defined. Here, we identify ubiquitin-fold modifier 1 (UFM1), a ubiquitin-like protein, as a critical regulator of VSMCs plasticity and atherogenesis. In VSMCs stimulated with oxidized low-density lipoprotein (ox-LDL), UFM1 overexpression markedly attenuated phenotypic switching, restoring contractile features and suppressing synthetic activation, accompanied by reduced proliferation and migration. In contrast, UFM1 knockdown further exacerbated these phenotypic alterations. In ApoE Show less

Previous Genome-wide association studies have identified several single nucleotide polymorphisms (SNPs) associated with Alzheimer's disease (AD), whereas their associations with mild cognitive impairment (MCI) remain unclear. To evaluate the associations between 100 representative AD-associated SNPs and susceptibility to MCI in the Chinese population. We recruited 200 MCI patients and 200 cognitively-healthy controls from the community, matched for age and sex. Associations between SNPs and MCI risk were estimated using lasso regression, adjusted for APOE status, using different genetic models. Fifteen SNPs in nine genes (including CLU, SORL1, PICALM, BDNF, NOS3, MTHFR, TOMM40, BIN1, and PVRL2) were associated with MCI in single-SNP analysis. In the multi-SNP association test, rs1801133 and rs9331888 of CLU were consistently associated with MCI risk in the dominant model. TOMM40 rs2075650 (G) was associated with MCI risk in the dominant model by age and education (OR = 2.41, 95%CI = 1.27-4.59), but disappeared when further adjusted for APOEε4 status. PICALM rs561655 (G) (OR = 0.52, 95%CI = 0.30-0.92) and NOS3 rs1549758 (T) (OR = 0.53, 95%CI = 0.30-0.94) were identified as protective genetic factors of MCI for the first time in dominant model combined with the APOEε4 allele. Moreover, MTHFR rs1801133 (A) and CLU rs9331888 (G) showed more susceptibility to MCI in the additive model. SORL1 rs641120(G) showed a protective effect, whereas BIN1 rs5733839 consistently showed a risk effect for MCI in the overdominant model, regardless of APOEε4 status. This study suggests that some AD-associated SNPs are associated with cognitive decline and may have important implications for future studies. Show less

Acute alcohol consumption is known to exert widespread physiological effects, yet the immediate impacts on metabolic biomarkers remain incompletely understood. The present randomized controlled trial was conducted to investigate the acute effects of a single episode of alcohol ingestion on various biomarkers in healthy individuals. A total of 45 male participants were recruited and randomized into an alcohol group (n = 40) and a control group (n = 5) at an 8:1 ratio. Volunteers in the alcohol group ingested 40% Absolut vodka within 15 min. Blood pressure, heart rate, and blood oxygen saturation were measured at 0 h, 1 h, 3 h, 5 h, 12 h, and 24 h. Venous blood samples were drawn at 0 h, 1 h, 5 h, 12 h, and 24 h after alcohol intake. Our results showed that levels of liver function markers, including α-fucosidase (AFU), albumin (ALB), and alkaline phosphatase (ALP), were significantly increased in the alcohol group compared to the control group. The 24-h area under curve (AUC) of AFU, ALB, and ALP were significantly higher in the alcohol group. The liver fibrosis maker collagen type Ⅳ (Ⅳ-C) tended to be higher at 1 h and 12 h in the alcohol group compared to the control group. Lipid levels, including triglycerides (TG), apolipoprotein A1 (APOA1), and the APOA1/APOB, were significantly elevated after alcohol ingestion, particularly at 5 h and 12 h. The 24 h-AUC of TG, APOA1, and APOA1/APOB were higher in the alcohol group than in the control group. Additionally, cardiac function indicators, including heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP), were significantly elevated in the alcohol group. SBP and DBP remained higher 24 h after alcohol ingestion compared to the control group. This study demonstrated that even a single episode of binge drinking could induce significant alterations of biomarkers related to liver function, cardiac function, and lipid profiles. These findings provided valuable insights into the short-term impact of alcohol on health and highlighted the importance of further research to explore the long-term implications of repeated acute alcohol exposure. Given the very small control group, these results should be interpreted as preliminary and confirmed in larger, more balanced randomized trials.

With the widespread use of smartphones among adolescents, smartphone addiction has become a growing mental health concern. Adolescents' limited self-regulation makes them particularly vulnerable to using smartphones to escape real-life stress, heightening addiction risk. However, the heterogeneity of addictive behaviors and the dynamic role of experiential avoidance have been underexplored. This 6-month longitudinal study surveyed 547 Chinese primary and secondary students using the Smartphone Addiction Scale (SAS) and the Acceptance and Action Questionnaire-II (AAQ-II). Latent profile analysis (LPA) and latent transition analysis (LTA) were applied to identify subgroups and examine transitions between these subgroups. Cross-lagged panel network analysis (CLPN) revealed key symptom interactions between experiential avoidance and addiction. The study identified two addiction subgroups: a stable "low-risk group" (84.9 percent) and a "high-risk group," 51.4 percent of whom transitioned to low risk over time. Logistic regression showed that experiential avoidance significantly predicted high-risk membership (odds ratios [OR] = 1.083-1.102) and deterioration within the low-risk group (OR = 1.036). The CLPN identified "online intimacy" (SPA-3) and "hesitation and overcautious" (EA-7) as driver nodes, with "withdrawal symptoms" (SPA-2) serving as a central node. These findings emphasize the crucial role of experiential avoidance in adolescent smartphone addiction and suggest symptom-level targets for early intervention. The results support acceptance and commitment therapy (ACT) as a promising approach for reducing smartphone addiction among youth. Show less

Elucidating effective components and mechanisms of traditional Chinese medicine (TCM) formulas remains a critical challenge for modernization. ErShiWei RouDouKou Pills (ESWRDK), a Tibetan formula with cardiovascular potential, lacks systematic exploration of its anti-atherosclerotic (AS) material basis and mechanisms. A novel six-stage cascade focused strategy integrating three-dimensional filtering mode, qualitative characterization, multi-component quantification, anti-AS efficacy, multi-lipidomics and bioactive compounds evaluation was proposed, advancing TCM research by holistic and multi-layered approach. UHPLC-MS combined with mass defect-ion intensity filtering (MD-ITF), DPIs, Nl and FBMN employed for profiling. Nine characteristic components were quantitated. A 12-week high-fat diet was fed to ApoE Firstly, the MD-ITF method and structural classification was established for complicated matrix. Secondly, 426 chemical components including 74 low-abundance were characterized. Thirdly, 9 characteristic components were quantified, and content distribution were profiled. Fourthly, ESWRDK reduced lipids, inflammation, and aortic plaques in AS mice. Fifthly, a total of 38, 23 and 48 differential biomarkers were identified predominantly linked to glycerophospholipids (GP) metabolism. WB confirmed ESWRDK downregulated hepatic PLA2, upregulated p-AMPK/AMPK and PPAR-α, and suppressed SREBP-1, orchestrating and mitigating lipid dysregulation. Finally, dehydrodiisoeugenol and agarotetrol bound PLA2, formed stable 1:1 static quenchingand inhibited PLA2 activity in vitro.

Aging worsens Alzheimer's disease (AD) peripheral metabolism and central pathology, yet few interventions are effective when started late. Methionine restriction (MR) induces the hepatokine FGF21 and may protect brain function, but its efficacy and mechanisms when started late are unclear. Fourteen-month-old male APP/PS1 mice received 17 weeks of MR (0.17% methionine); behavioral, histological, and molecular assays were performed and hippocampal FGFR1 was knocked down by adeno-associated virus. Late-life MR improved peripheral glucose/lipid profiles, reduced Aβ deposition, preserved synaptic markers, and suppressed neuroinflammation. MR-induced hepatic FGF21 and brain FGFR1-AMPKα signaling to inhibit NFκB; hippocampal FGFR1 knockdown abolished MR's neuroprotective effects while leaving peripheral metabolic changes intact. Even when initiated in late life, MR robustly reduces AD pathology via the hepatic FGF21-brain FGFR1 axis, independent of peripheral metabolic changes. These preclinical findings position MR and FGF21-FGFR1 axis as actionable late-life intervention targets with potential for clinical translation. Show less

BackgroundCognitive impairment is increasingly prevalent in younger populations. The interplay between environmental exposures like noise and genetic susceptibility in dementia etiology remains unclear. This study investigated the combined effects of work-related cumulative noise exposure (WCNE) and genetic polymorphisms on cognitive performance.ObjectiveTo examine the relationships among WCNE, genetic factors (APOE rs429358/rs7412 and PS-1 rs165932), and lower cognitive performance (LCP), and to analyze the potential interaction.MethodsThis study included 523 workers from a health surveillance cohort in western China. WCNE was assessed for each participant. Genotyping was performed for APOE (rs429358/rs7412) and PS-1 (rs165932) polymorphisms. Cognitive function was evaluated via Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The individual and combined effects of WCNE and genetic factors on LCP were analyzed.ResultsAPOE rs429358/rs7412 were not significantly associated with LCP. The PS-1 rs165932T allele (PS-1T) was associated with LCP (p < 0.05). The adjusted odds ratios (aORs) for LCP (evaluated by MMSE and MoCA) in the PS-1T group were 2.443 (95% CI: 1.149-5.195) and 2.065 (95% CI: 1.091-3.906), respectively. Age and WCNE had an interaction effect on the LCP for both MMSE and MoCA (p < 0.05), while PS-1T had an effect modification on the relationship between WCNE and LCP (p < 0.05).ConclusionsThese findings highlight the urgent need to identify and mitigate noise exposure risks in vulnerable populations. These findings also provide evidence for further mechanistic studies exploring how noise, aging, and genetic susceptibility contribute to cognitive impairment through underlying biological mechanisms.

Calcific aortic valve disease (CAVD), the most common human valve disease on a global scale, ranks and persists as an unaddressed clinical challenge. This is primarily attributed to the absence of efficacious pharmacological approaches. The Nuclear Receptor Subfamily 4 Group A Member 1 (NR4A1), intricately associated with the pathogenesis of multiple cardiovascular diseases, has emerged as a pivotal target for the diagnosis and treatment of numerous ailments. However, the specific molecular mechanisms and the functional significance of NR4A1 in the pathogenesis of CAVD are yet to be comprehensively elucidated. By performing in-depth analyses on human aortic valve tissues and carrying out functional investigations using primary valvular interstitial cells (VICs), we were able to demonstrate that NR4A1 significantly facilitated cellular proliferation and intensifies the osteogenic differentiation process of VICs. Evidently, this is reflected in the elevated expression of key osteogenic markers, namely runt-related transcription factor 2 (RUNX2) and alkaline phosphatase (ALP). Mechanistically, the pro-calcific effects were achieved via NR4A1-dependent modulation of the cell cycle regulatory protein Cyclin D2 (CCND2). Significantly, Show less

Endometrial carcinoma (EC) is a common malignancy of the female reproductive system. Rab35 is widely recognized as an oncogenic driver and has been implicated in the progression of various malignant tumors. However, its regulatory mechanism and pathobiological roles in EC remain unclear. Rab35 expression in EC was systematically profiled via integrative analysis of clinical endometrial specimens and multi-omics databases (CPTAC and GEO). The association between clinical prognosis and Rab35 expression was examined using Kaplan-Meier analysis. Mechanistic investigations included transwell assays, western blotting, and immunofluorescence in Rab35-overexpressing and CRISPR/Cas9-mediated Rab35-knockout EC cells. A mouse xenograft tumor model was established to confirm the effects of Rab35 in vivo. The Rab35 content increased gradually from normal endometrium to atypical hyperplastic endometrium to EC. Moreover, the findings indicated that elevated Rab35 expression was significantly associated with advanced disease characteristics and poor overall survival in patients with EC. In addition, Rab35 enhanced the migratory and invasive nature of EC cells. The expression of Rab35 was inversely linked to that of the β-catenin destruction complex-related proteins Axin-1 and GSK3β, leading to the increased nuclear translocation of β-catenin in EC cells. Animal experiments further verified that Rab35 augmented EC progression by regulating the nuclear translocation of β-catenin. The study revealed that high expression of Rab35 was strongly correlated with EC progression and a poor clinical outcome. Furthermore, Rab35 promoted EC cell metastasis by accelerating the nuclear translocation of β-catenin. These findings suggest that Rab35 serves as a valuable biomarker and therapeutic target for EC.

Previous research has suggested that high levels of internet use are associated with lower levels of physical activity. However, recent studies have yielded mixed findings. First, we aim to explore the prevalence of internet addiction and sedentary behavior among college students. Second, we examine the relationship between sedentary behavior and body composition. Additionally, we employ latent profile analysis (LPA) to identify subgroups of internet addiction profiles and to explore the associations between these latent profiles and sedentary behavior. This cross-sectional study examined the relationship between sedentary behavior, internet addiction, and body composition among 369 Chinese college students. Sedentary behavior was assessed via self-reported sitting time, internet addiction was measured using a standardized questionnaire, and body composition was evaluated with the InBody 120 device. LPA, an individual-centered method, was used to identify homogeneous subgroups of internet addiction. 42.3 % of students exhibited internet addiction and 72.6 % reported ≥6 h of daily sitting. LPA revealed two distinct profiles of internet addiction-"Regular" (57.2 %) and "Internet addiction" (42.8 %)-highlighting its heterogeneous nature. The findings suggest that age (p = 0.296), gender (p = 0.304), and sedentary time (p = 0.954) may not be the primary factors contributing to these profiles. Policymakers and campus health programs should tailor interventions to distinct internet addiction subgroups.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by irreversible cognitive decline and synaptic dysfunction and represents the most prevalent etiology of dementia, accounting for an estimated 60-70% of all clinically diagnosed cases worldwide. The growing focus on microglia-neuron interactions in AD research highlights their diverse, region-specific responses, which are driven by the functional and pathological heterogeneity across different brain regions. Therefore, investigating the interactions between microglia and neurons is of crucial importance. To explore the regional heterogeneity of microglia-neuron crosstalk in AD, we integrated human single-nucleus RNA sequencing data from the prefrontal cortex (PFC), hippocampus (HPC), and occipital lobe (OL) provided by the ssREAD database. Our study delineated four microglial subtypes and uncovered a pseudotime trajectory activation trajectory leading to the disease-associated microglia (DAM) phenotype. The transition along this trajectory is driven and stabilized by a key molecular switch: the coordinated downregulation of inhibitory factors (e.g., LINGO1) and upregulation of immune-effector and antigen-presentation programs, which collectively establish the pro-inflammatory DAM state. Furthermore, we observed that each brain region displayed unique microglia-neuron communication patterns in response to AD pathology. The PFC and OL engage a THY1-ITGAX/ITGB2 signaling axis; the HPC predominantly utilizes the PTPRM pathway. Notably, THY1 dysregulation strongly correlates with pathology in the PFC, HPC, and OL, suggesting that microglia-neuron crosstalk in AD possesses both heterogeneity and commonality. The main contribution of this study is the systematic characterization of region-specific microglia-neuron interactions and the identification of THY1 as a potential mediator that may be targeted therapeutically to modulate microglial function in affected brain regions.

The angiopoietin-like protein (ANGPTL)3/8 complex regulates triglyceride partitioning, and its selective blockade lowers triglycerides while raising HDL-cholesterol (HDL-C). Clinical and genetic evidence support ANGPTL3/8 antagonism as a precision therapy for mixed dyslipidemia, monogenic hypertriglyceridemia (CREBH or APOA5 deficiency), and diabetic dyslipidemia by correcting a fundamental disturbance in lipid partitioning.

Depression is a heterogeneous psychiatric disorder with limited treatment efficacy, as 30-50% of patients exhibit inadequate responses to conventional monoaminergic antidepressants. Rhein, a bioactive anthraquinone derived from Rheum palmatum, exhibits rapid and sustained antidepressant effects in both acute and chronic social defeat stress (CSDS) mouse models. Using quantitative proteomics on prefrontal cortex (PFC) samples from control, CSDS, Rhein-treated, and imipramine-treated cohorts, we identified differentially expressed proteins that revealed Rhein's multi-target regulatory profile. Functional enrichment and clustering analyses indicated that Rhein predominantly restores dysregulated pathways related to lipid metabolism, ribosomal translation, mitochondrial and endoplasmic reticulum (ER) function, and synaptic plasticity, forming a coherent mechanistic axis underlying its therapeutic effects. Comparative analysis with imipramine-treated mice further highlighted Rhein's distinct capacity to modulate organelle homeostasis and synaptic remodeling with greater breadth. Parallel reaction monitoring (PRM) and Western Blotting validated key proteins involved in mitochondrial functions (BNIP1, PISD, MRPL42, MRPS30, LRBA, IGHM), ER homeostasis (ACBD5, APOA4, RPL14), and synaptic plasticity (HDAC1, FAM3C, SSU72). These molecular findings suggest that Rhein exerts its antidepressant effects by restoring the functional integrity of mitochondria and the ER, thereby reprogramming synaptic plasticity. We inferred that this organelle-centered regulation further reinforces its potent modulation through multiple mechanisms and signaling pathways of synaptic plasticity, enabling Rhein to exert antidepressant effects through a coordinated, multi-layered mechanism. Collectively, our findings provide a systems-level mechanistic framework for Rhein's antidepressant efficacy and support its potential as a multi-pathway natural therapeutic, particularly for metabolic subtypes of depression.
