Wilms tumor (WT), the most common pediatric malignant renal tumor, shows high recurrence in high-risk subtypes due to chemoresistance. Tumor microenvironment (TME) remodeling, particularly M2-type tumor-associated macrophages (TAMs), contributes to chemoresistance, but underlying mechanisms remain unclear. This study explored TME-related chemoresistance mechanisms in WT and developed targeted therapeutic strategies. Clinical WT samples were analyzed for M2-type TAMs infiltration and SNRPC expression. Bioinformatics analysis of TARGET-WT data identified M2-associated genes. In vitro experiments (cell transfection, qRT-PCR, Western blot, co-culture, ChIP and dual-luciferase reporter assays) explored SNRPC’s role in regulating M2-type TAMs. Animal models (orthotopic tumor and lung metastasis) verified in vivo effects. A hybrid exosome nanosystem (DOX/siSNRPC@hEVs) was constructed and evaluated for efficacy and safety. Statistical analyses included t-test, ANOVA, and survival analysis. M2-type TAMs (CD68⁺CD163⁺) infiltration was higher in chemoresistant WT and associated with poor prognosis. SNRPC was overexpressed in chemoresistant WT, correlated with M2-type TAMs, and promoted tumor malignancy and M2-type TAMs polarization. Mechanistically, SNRPC activated NF-κB signaling, inducing CXCL17 upregulation to recruit M2-type TAMs, with partial CXCL17 release via migrasomes. DOX/siSNRPC@hEVs showed high targeting, reduced toxicity, inhibited tumor growth/metastasis, and reversed chemoresistance by reducing M2-type TAMs. The SNRPC-NF-κB-CXCL17-M2 TAMs axis drives WT chemoresistance. DOX/siSNRPC@hEVs effectively targets this axis, providing a novel strategy for high-risk WT.

While VPS13C is a recessively inherited Parkinson's disease (PD) gene, its potential dominant effects in idiopathic Rapid-eye movement (REM) sleep behavior disorder (iRBD) remain unexplored. The relation between its monogenic form and the onset of PD suggested that subtype specificity may need to be considered. We examined the presence of likely pathogenic VPS13C variants in 150 iRBD and 180 α-synucleinopathy patients (iRBD-first and movement disorder-first). VPS13C variants were significantly enriched in iRBD patients, and ten iRBD risk variants have been identified. iRBD risk VPS13C variant carriers demonstrated more severe RBD symptoms and greater autonomic dysfunction, correlating with REM sleep EEG and autonomic network activity abnormalities. Notably, enrichment was specific to the iRBD-first α-synucleinopathy subtype, and iRBD risk VPS13C variant carriers showed accelerated progression to overt α-synucleinopathy. These results suggest that VPS13C not only contributes to iRBD susceptibility but also serves as a marker for the iRBD-first α-synucleinopathy and faster disease conversion. Show less

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a highly prevalent chronic liver disease worldwide and is closely associated with obesity, diabetes, and other metabolic disorders. Because MASLD progression poses serious health risks, elucidating the underlying mechanisms is essential to guide early intervention and therapeutic strategies. Proteomic analysis was used to identity high-fat diet (HFD)-induced proteins in mouse liver. Galectin-1 (GAL1) expression was assessed via immunohistochemistry in human liver tissues. Liver-specific GAL1-deficient mice were generated using adeno-associated virus. Mice were fed either a chow diet or an HFD. Functional studies were performed in cell lines using western blotting, RT-qPCR, immunofluorescence, co-immunoprecipitation, mass spectrometry, and molecular docking analysis. GAL1 expression was elevated in liver tissues from patients with MASLD and in mouse models. Liver-specific GAL1 knockdown alleviated hepatic steatosis and enhanced fatty acid oxidation (FAO). Mechanistically, GAL1 competitively bound to the BRCT domain of poly (ADP-ribose) polymerase 1 (PARP1), thereby interfering with its interaction with the WW domain -containing E3 ubiquitin protein ligase 2 (WWP2). Hepatic GAL1 knockdown promoted the PARP1 -WWP2 interaction and subsequently facilitated ubiquitin-dependent degradation of PARP1. This degradation led to increased NAD Hepatic deficiency of GAL1 alleviates hepatic steatosis by enhancing FAO through promotion of ubiquitin-dependent PARP1 degradation, thereby restoring NAD Show less

Granulosa cell (GC) apoptosis is intrinsically linked to the ovarian dysfunction of polycystic ovary syndrome (PCOS). Although oxidative stress and apoptosis in GCs have been detected in PCOS patients, how reactive oxygen species (ROS) links to GC apoptosis in PCOS remains to be further elucidated. Here, by integrating public single-cell RNA-seq data with clinical GC sample validation, we found that the expression of the E3 ubiquitin ligase WWP2 was significantly reduced, whereas its role in PCOS has not been previously reported. Notably, we first demonstrated that WWP2 overexpression can effectively antagonize mitochondrial apoptosis and ROS in KGNs. Mechanistically, oxidative stress weakened the interaction between WWP2 and BAK and reduced WWP2 expression, thereby suppressing BAK ubiquitination at Lys113. This inhibition impaired proteasomal degradation and consequently increased BAK protein levels. Consistently, disrupting BAK ubiquitination (BAK-K113R mutant) or knocking down WWP2 facilitated KGN apoptosis, and genetic ablation of Wwp2 in PCOS mice further aggravated GC apoptosis and hormonal disturbances. This study elucidates the molecular mechanism by which oxidative stress modulates GC mitochondrial apoptosis through WWP2-mediated BAK ubiquitination, and establishes WWP2 as a potential therapeutic target for PCOS.

Osteoarthritis (OA) represents a prevalent degenerative joint condition, in which chondrocyte dysfunction plays a key role in disease progression. Although accumulating evidence underscores the importance of cellular stemness regulation in OA development, systematic screening of related biomarkers has been insufficient. The current study sought to discover and validate potential biomarkers through bioinformatics and machine learning (ML), offering novel perspectives for early detection and therapeutic intervention in OA. The present study examined six OA-related transcriptomic profiles from the Gene Expression Omnibus (GEO) to discover and validate stemness-associated biomarkers. Differentially expressed genes (DEGs) were selected and analyzed for enriched biological functions. OA-related modules were determined via weighted gene coexpression network analysis (WGCNA). Key stemness-related genes were selected using ML algorithms, including support vector machine (SVM), random forest (RF), extreme gradient boosting (XGBoost), and the least absolute shrinkage and selection operator (LASSO) regression. Receiver operating characteristic (ROC) analysis was implemented to determine diagnostic accuracy. Utilizing single-sample gene set enrichment analysis (ssGSEA), the link with immune cell infiltration was examined. Ultimately, immunohistochemistry was employed for experimental validation. Intersection analysis identified 56 stemness-related DEGs in OA cartilage. WGCNA analysis yielded 7 modules significantly associated with stemness genes, and a combined screening approach identified 60 candidate genes. Using four machine learning algorithms-SVM, LASSO, XGBoost, and RF-four feature genes were ultimately determined (WWP2, CDKN1A, IL11, and CRTAC1), among which WWP2, CDKN1A, and CRTAC1 showed significant differential expression between OA and normal samples and demonstrated good diagnostic performance in both the training and validation cohorts (AUC > 0.7). ssGSEA analysis revealed that the expression of these three genes was significantly correlated with specific immune cell subpopulations. Immunohistochemistry further confirmed that WWP2 and CDKN1A were downregulated in OA tissues, whereas CRTAC1 was upregulated. Through bioinformatics analysis and IHC validation, we identified three stemness-associated biomarker genes (WWP2, CDKN1A, CRTAC1) in OA. These findings may provide meaningful implications for future clinical assessment, treatment, and research on OA. Show less

Myocardial hypertrophy is one of the most prominent features of heart failure. SET domain-containing protein 7 (Setd7), a catalytic enzyme responsible for histone H3K4 methylation, has been implicated in various cardiac diseases. In this study we investigated whether Setd7 contributed to the development of cardiac hypertrophy. Male mice were subjected to a hypobaric hypoxic environment for 8 weeks; neonatal rat cardiomyocytes (NRCMs) exposed to hypoxia for 6 h. We showed that hypoxic stimulation significantly upregulated the expression levels of Setd7 along with the expression of hypertrophic markers ANP and BNP in NRCMs. By conducting loss- and gain-of-function assays, we demonstrated that Setd7 modulated the hypertrophic and inflammatory markers in hypoxic cardiomyocytes. We further revealed that Setd7-mediated activation of E2F1 (E2 promoter binding factor 1) triggered the expression of E3 ubiquitin protein ligases WWP2, which catalyzed the ubiquitination and degradation of glutathione peroxidase 4 (GPx4), a critical lipid peroxide-reducing enzyme. This degradation drove extensive lipid peroxidation, thereby exacerbating pathological cardiac hypertrophy. Notably, GPx4 inhibition by ras-selective lethal small molecule 3 (RSL3) abolished the antihypertrophic effects of Setd7 knockdown in cardiomyocytes, underscoring the pivotal role of lipid peroxidation in Setd7-mediated hypertrophic responses. In summary, Setd7 promotes hypoxia-induced cardiac hypertrophy through the Setd7-E2F1-WWP2-GPx4 signaling pathway, suggesting that targeting Setd7 is a promising therapeutic strategy to alleviate hypoxia-induced myocardial hypertrophy.

Hypothalamic obesity (HO) is a disabling disease caused by central nervous system (CNS) damage due to neurosurgery, trauma, or tumors, especially in hypothalamus. The pathological mechanism of its neural circuits is still unclear, and there is currently no corresponding drug due to the complex etiology. G protein-coupled receptors (GPCRs) regulate neural function in many CNS diseases. Among them, melanocortin 4 receptor (MC4R) regulate metabolism and appetite in the hypothalamus. Setmelanotide, an MC4R agonist, has demonstrated anti-obesity effects in genetic forms of obesity; however, its efficacy and mechanisms in HO remain unexplored. This study explored the potential of treating HO by setmelanotide-targeted activation of MC4R in the paraventricular nucleus (PVN). We established a rat hypothalamic injury model to replicate human HO symptoms, such as hyperphagia (50% increase in food intake), elevated Lee index, and more than 25% weight gain. Immunofluorescence and immunoblot analysis showed that HO disrupted the PVN neuropeptides, leading to the inhibition of MC4R via calmodulin-dependent protein kinase kinase 2 (CaMKK2) and AMP-activated protein kinase (AMPK) signaling. Crucially, administration of setmelanotide restored CaMKK2/AMPK activity, reactivated MC4R neurons, and normalized appetite and feeding behavior during fasting-refeeding and the long-term treatment of obese rats (60% reduction in food intake), ultimately reversing obesity (23% weight loss). These findings underscore the critical role of MC4R dysfunction in hypothalamic injury and highlight the strategies to pharmacologically activate MC4R via CaMKK2/AMPK signaling to restore metabolic homeostasis, proposing a translatable therapeutic agent to manage obesity caused by CNS injury.

Tissue acidification is a common feature of hypoxia, inflammation and solid tumor. Acidic pH regulates innate immune response in macrophages by weakening BRD4-containing transcriptional condensates. Yet how disruption of transcriptional condensates leads to gene-specific regulation of immune programs remain unclear. Here, we integrated ATAC-seq, ChIP-seq, and RNA-seq of primary murine macrophages and performed integrative epigenomics analyses to identify transcriptional regulators (TRs) with pH-sensitive regulatory potential and association to BRD4-dependent transcriptional condensates. We determined pH-dependent super-enhancers (SEs) by extended profiles of BRD4 binding and h3K27ac marks. We found RELA, IRF family, and STAT family as candidate TRs enriched at BRD4-associated, pH-sensitive SE regions. RELA and IRF3 preferentially occupied BRD4-associated and pH-sensitive SEs, and displayed markedly reduced binding under acidic conditions, aligning with BRD4 occupancy change. Correspondingly, immune-response genes within BRD4-associated, pH-sensitive SE regions, including Show less

Systemic delivery of adeno-associated virus serotype 9 (AAV9) to the central nervous system (CNS) is insufficient due to hindrance from the tight junctions of the blood-brain barrier (BBB). While peptide-display-based AAV engineering has advanced CNS-targeting capsid development, traditional strategies inserting or substituting a 7-mer peptide remain limited by low success rates and scarcity of efficient variants. To address these issues, we developed the Multiple Capsid Mutation Strategies (MCMS) library, which enhanced sequence diversity by incorporating random peptide insertions flanked by AAV9 or variant-derived residues and peptide substitutions within the VR-VIII of the AAV9 capsid protein. Following capsid selection in mice, the leading AAV variant BRC06 was identified and validated across different mouse strains. BRC06 exhibited approximately 1.9-fold higher brain transgene expression than AAV.PHP.eB in C57BL/6J mice. In BALB/c mice, BRC06 achieved a 1,482-fold brain enhancement with a 92-fold liver reduction relative to AAV9. Sequence analysis revealed that BRC06 was derived from the MCMS library's substitution strategies. Additionally, host factor screening revealed AAVR-dependent entry with accessory factors like Show less

Ulcerative colitis (UC) is a prevalent chronic gastrointestinal disease. Gene plays an important role in UC pathogenesis. Therefore, we aim to identify UC susceptibility genes and specific cell types expressing these genes. We conducted a cross-tissue transcriptome-wide association study by integrating UC GWAS with 49 tissues gene expression matrix from the Genotype-Tissue Expression project. Subsequently, we employed Functional Summary-based Imputation to verify candidate genes within colon tissue. Conditional and Joint Analysis was utilized to filter out genes potentially influenced by linkage disequilibrium. Multimarker Analysis of Genomic Annotation was then applied to pinpoint genes relevant to UC. Validation of the selected genes was performed using Mendelian randomization. GeneMANIA analysis was conducted to elucidate biological functions of identified genes. Finally, single-cell RNA sequencing was employed to ascertain cell types in which these genes are enriched. The cross-tissue transcriptome-wide association study, Functional Summary-based Imputation and Multimarker Analysis of Genomic Annotation analyses identified a total of 5 genes, of which 3 genes, ADCY3, ITGB6, and MTMR3, were retained after Mendelian randomization. These genes were found to be implicated in several functional pathways, including the cyclic AMP metabolic process and phosphorus-oxygen lyase activity. Furthermore, we observed ADCY3 predominantly enriched in B cells, while ITGB6 and MTMR3 enriched in epithelial cells. Our study has identified 3 genes associated with UC susceptibility. These findings not only enhance our understanding of the genetic underpinnings of UC, but also offer novel avenues for exploring molecular mechanisms and potential therapeutic targets for UC.

Patients with obstructive sleep apnea (OSA) experience chronic intermittent hypoxia (CIH). OSA patients and CIH-treated rodents exhibit overactive sympathetic nervous system and hypertension, mediated through hyperactive carotid body (CB) chemoreflex. Activation of olfactory receptor 78 (Olfr78) by hydrogen sulfide (H2S) is implicated in CB activation and sympathetic nerve responses to CIH, but the downstream signaling pathways remain unknown. Given that odorant receptor signaling is coupled to adenylyl cyclase 3 (Adcy3), we hypothesized that Adcy3-dependent cyclic adenosine monophosphate (cAMP) contributes to CB and sympathetic responses to CIH. Our findings show that CIH increases cAMP levels in the CB, a response absent in Adcy3, Cth (encoding CSE), and Olfr78 null mice. CBs from Cth and Olfr78 mutant mice lacked a persulfidation response to CIH, indicating that Adcy3 activation requires Olfr78 activation by H2S in CIH. CIH also enhanced glomus cell Ca2+ influx, an effect absent in Cnga2 (encoding cyclic nucleotide-gated channel alpha2 subunit) and Adcy3 mutants, suggesting that CIH-induced cAMP mediates enhanced Ca2+ responses through cyclic nucleotide-gated channels. Furthermore, Adcy3 null mice did not exhibit either CB activation or sympathetic activation by CIH. These results demonstrate that Adcy3-dependent cAMP is a downstream signaling pathway to H2S/Olfr78, mediating CIH-induced CB activation, sympathetic activity and hypertension. Show less

This study examined the regulatory effects of Acceptance and Commitment Therapy (ACT) on T lymphocyte subsets, serum inflammatory cytokines, neurotrophic factors, antioxidant enzymes, and lipid peroxidation products in elderly cerebral stroke (CS) patients, providing insights into the multi-dimensional pathophysiological interactions and potential intervention strategies for chronic stroke recovery. In this randomized controlled trial, 120 elderly stroke patients were allocated to either an ACT group (ACT intervention; n = 60) or a routine group (conventional treatment; n = 60). Comprehensive assessments were performed to quantify: (1) peripheral T lymphocyte distribution (CD3+, CD4+, CD8+ subsets, and CD4+/CD8+ ratio), (2) serum inflammatory cytokines (IL-1p, IL-6, IL-10, and TNF-a), (3) neurotrophic factors (5-HT, NE, BDNF, and IGF-1), and (4) antioxidant enzymes (SOD, CAT) and lipid peroxidation products (MDA, NO) using flow cytometry, HPLC-ECD, and ELISA. Statistical analyses were conducted with SPSS 22.0. Following treatment, CS patients exhibited reduced CD3+ and CD4+ T-cell levels along with a decreased CD4+/CD8+ ratio, while CD8+ T-cell proportions were elevated (P< 0.05). Proinflammatory cytokine levels (IL-1 b, IL-6, and TNF-a) were significantly suppressed, whereas anti-inflammatory IL-10 expression increased (P < 0 .0 5 ). Notably, ACT demonstrated superior efficacy in restoring immune balance and attenuating inflammation compared to conventional intervention (P< 0.05). Furthermore, neurotrophic factors levels were elevated, and oxidative stress markers were ameliorated in CS after treatment (P< 0.05), suggesting that ACT enhances neurotrophic activity and mitigates oxidative injury. ACT likely confers neuroprotection through multi-target mechanisms, including modulation of T-cell subset homeostasis, upregulation of neurotrophic factors, and suppression of oxidative stress.

Inflammatory bowel disease (IBD) is a chronic, immune-mediated intestinal disorder driven by dysregulated immune responses in genetically susceptible individuals. Despite recent advances in treatment, more than 30% of patients either fail to respond initially or lose response over time, underscoring the need for a deeper mechanistic understanding of immunogenetic pathways and the development of individualized therapeutic strategies. We first discuss how newly identified susceptibility genes (e.g., IL23R, NOD2, BDNF, SLC) and their polymorphisms influence immune cell function and epithelial barrier integrity. Single-cell technologies have further revealed novel cell subsets and interactions underlying disease heterogeneity. We then explore the clinical efficacy of classical and emerging targeted therapies, including cytokine-specific biologics, JAK inhibitors, and novel strategies aimed at restoring regulatory T-cell function or blocking integrin-mediated lymphocyte trafficking. Additionally, we highlight promising therapeutic approaches such as fecal microbiota transplantation, microbial metabolite-based interventions, and nanotherapeutics. We further discuss how genetic insights and immune biomarkers can facilitate treatment personalization and improve prognostic stratification. Ultimately, this review emphasizes the transition from broad immunosuppression to precision medicine and proposes integrated approaches-combining multiomics profiling, immune monitoring, and novel therapeutics-to achieve sustained remission and improve long-term outcomes in IBD patients.

Memory function is susceptible to decline with age, stress, and neurological diseases, highlighting the importance of exploring effective and sustainable strategies to enhance memory consolidation. Epinephrine plays a key role in memory consolidation; acute, moderate elevations enhance memory, while chronic high levels are inhibitory. Given the limitations of pharmacological interventions, this study aims to investigate exercise as a non-pharmacological means to promote post-learning memory consolidation by inducing acute epinephrine release, focusing on its mechanisms and optimized implementation strategies. This narrative review systematically reviews evidence from neurophysiology, molecular biology, and behavioral experiments and finds that exercise can safely and controllably activate the sympathetic-adrenal system, leading to a rapid rise in epinephrine. The release kinetics align highly with the critical time window for memory consolidation. Moderate-intensity aerobic exercise implemented within 30 min post-learning can significantly improve memory retention. The mechanisms involve not only epinephrine enhancing synaptic plasticity and LTP by activating hippocampal β-adrenergic receptors, but also synergistic effects across multiple systems, such as promoting osteocalcin signaling, upregulating BDNF expression, inducing neurogenesis, and optimizing cerebral metabolism and blood flow. Evidence suggests that exercise, as a non-pharmacological intervention, significantly enhances post-learning memory consolidation through the precise modulation of epinephrine release and multi-system synergy, offering both high efficacy and safety. Future research should focus on developing precise exercise prescriptions based on individual characteristics and leveraging wearable devices and digital technologies to improve intervention adherence and applicability, promoting its widespread use in educational and clinical settings.

The increasing global aging population presents significant challenges related to cognitive decline, mental health disorders, and social isolation. Martial arts exercise emerges as a multifaceted intervention promoting mental health and cognitive vitality among older adults by integrating physical activity, cognitive engagement, and social interaction. This review synthesizes evidence on the neural mechanisms underlying the benefits of martial arts, highlighting their role in enhancing brain-derived neurotrophic factor (BDNF) expression, neuroplasticity, and neural connectivity, which support improved executive functions, memory, and emotional regulation. Both hard martial arts and soft practices, such as Tai Chi, offer distinct advantages in addressing age-related cognitive and psychosocial challenges. Additionally, martial arts foster strong social support systems, reducing loneliness and enhancing emotional resilience through community engagement and shared achievement. Physical and functional benefits, including improved strength, balance, and cardiovascular health, further contribute to overall well-being. Despite promising results, current studies are limited by heterogeneity in martial arts styles, short intervention durations, and variable methodologies. Future research should focus on long-term, standardized interventions employing advanced neuroimaging and biomarker assessments to better elucidate mechanisms and optimize training protocols. Integrating martial arts into health promotion strategies holds substantial potential for enhancing mental health, cognitive resilience, and quality of life in aging populations. Show less

Retinal degenerative diseases (RDDs) cause irreversible vision loss with limited treatment options. Traditional Chinese medicine (TCM) formulas have demonstrated neuroprotective effects, yet their overall efficacy lacks comprehensive meta-evidence. The aim of this study was to exploratively evaluate the neuroprotective effects of TCM formulas in animal RDD models. A comprehensive literature search was conducted across eight electronic databases to identify animal studies that evaluated the neuroprotective effects of TCM formulas on RDDs. Pairwise meta-analysis and Bayesian network meta-analysis (NMA) were performed to synthesize evidence on key outcomes: neural growth, glial activation, oxidative stress, apoptosis factors, and ophthalmological parameters. Treatment rankings were assessed using the surface under the cumulative ranking curve (SUCRA). Twenty-four studies were included. The compositions and bioactive compounds of the TCM formulas have been defined and identified. Pairwise meta-analysis demonstrated that specific TCM formulas might exert neuroprotective effects on RDDs by regulating key biomarkers. Specifically, Zhen-Bao-Wan, Bu-Shen-Yi-Jing-Fang, and Qi-Shen-Yi-Qi pills modulated neural growth and glial activation by upregulating BDNF, CNTF, and reducing GFAP, respectively. Furthermore, Yi-Qi-Wen-Yang-Tong-Luo decoction, Zi-Yin-Ming-Mu decoction, and Yishi-Tablet suppressed oxidative stress and apoptosis by reducing SOD, retinal apoptotic cells and caspase-3, respectively. Additionally, Bu-Yang-Huan-Wu decoction improved retinal function by elevating ERG-a and ERG-b wave amplitudes. Subgroup analyses indicated that Bu-Yang-Huan-Wu decoction and Qu-Yu-Tong-Luo prescription exhibited superior efficacy in restoring retinal ganglion cell (RGC) counts and retinal thickness in specific RDD models. The NMA results indicated that the included TCM formulas exhibited target-specific and dose‒response trends, with different formulas showing preferential efficacy for distinct biomarkers. Given the limitations identified in this study, these findings should be interpreted as preliminary evidence to guide future research rather than as conclusive results. Future studies with rigorous experimental designs are needed to address these limitations and enhance translational relevance. This study provides preclinical and exploratory evidence that the included TCM formulas might exert neuroprotective effects on animal models of RDDs by modulating glial activation, promoting neuronal growth, and inhibiting oxidative stress and apoptosis. Additional high-quality preclinical studies are essential to validate these effects and inform future clinical translation. https://www.crd.york.ac.uk/PROSPERO/view/CRD420251002491 identifier CRD420251002491.

Neurotrophin signaling through NGF/TrkA and BDNF/TrkB is increasingly recognized as a driver of osteosarcoma (OS) progression and an organizer of its immune milieu, yet clinical translation has lagged amid intratumoral heterogeneity and a myeloid-skewed, vasculature-aberrant tumor microenvironment (TME). Features that blunt immune competence include dominant tumor-associated macrophage programs, sparse and dysfunctional effector T cells, endothelial remodeling that restricts lymphocyte entry, and neuron-immune circuits that reinforce suppression. Within this context, NGF/TrkA promotes matrix remodeling, monocyte ingress, and macrophage polarization, while BDNF/TrkB modulates dendritic-cell maturation, supports survival and angiogenesis, and may condition T-cell priming-together positioning neurotrophins as coordinators of tumor persistence and immune exclusion. This review surveys these mechanisms and maps them to therapeutic strategies: kinase-level blockade with approved TRK inhibitors in NTRK fusion-positive disease; exploratory pathway inhibition in fusion-negative OS; ligand-directed approaches; and rational combinations with immunotherapy and vascular/stromal modulators. We highlight biomarker frameworks (receptor-ligand activity scores, phospho-Trk immunohistochemistry, NGF-MMP-2 readouts) and safety considerations that should structure early-phase trials. Clinical and preclinical signals collectively support testing neurotrophin-targeted strategies to recalibrate myeloid composition, enhance antigen presentation, and restore T-cell access to tumor beds. The purpose of this review is to synthesize current evidence and propose a translational roadmap for targeting NGF/TrkA and BDNF/TrkB to remodel antitumor immunity in osteosarcoma. Show less

ASD is a neurodevelopmental disorder with specific core symptoms. Physical activity has been demonstrated to positively influence the pathological mechanisms underlying autism and to alleviate associated symptoms. A comprehensive synthesis was conducted by reviewing and integrating relevant literature. Literature review revealed that the mechanism of physical activity intervention in autism primarily involves modulation through neuronal factors, glial cells, and gut microbiota. Neuronal factors include brain-derived neurotrophic factor, axonal protein families, and neurotransmitters. Additionally, physical activity helps alleviate stereotypical behaviors and internal anxiety in individuals with ASD, reduce obesity and cardiovascular diseases in some patients, and enhance social communication skills.

Despite preclinical evidence for berberine's antidepressant potential, its pharmacological effects remain controversial.This study therefore systematically reviews animal research to clarify its mechanisms and support future clinical trials. We searched PubMed, Embase, Web of Science, Cochrane Library, and OVID for studies on berberine in depression models up to March 20, 2025. Analysis used STATA 15.0 and Review Manager 5.4, with study quality assessed via SYRCLE's risk of bias tool. The meta-analysis included 18 studies (338animals). Overall, berberine significantly reduced depression-like behaviors in animal models.Specifically, BBR increased total locomotor activity in the open field test (SMD=2.79, 95% CI: 1.55, 4.02) and time spent in the center zone (SMD=2.49, 95% CI:1.61, 3.37), reduced immobility time in both the forced swim test and tail suspension test (SMD =-4.42, 95% CI:-5.77,-3.07; SMD=-4.46, 95% CI:-6.21, -2.71), increased sucrose intake in the sucrose preference test (SMD = 3.72, 95% CI: 2.37, 5.07), and reduced feeding latency in the novelty-suppressed feeding test (SMD=-5.72, 95% CI:-7.63, -3.82). However, BBR did not significantly alter the number of square crossings (SMD=1.36, 95%CI:-0.07 , 2.79) or rearing frequency (SMD=1.66, 95% CI: -0.29, 3.61) in the open field test. BBR also increased the levels of body weight, brain-derived neurotrophic factor, dopamine, serotonin, and norepinephrine,while reducing the levels of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6. Preclinical studies suggest that berberine may represent a promising therapeutic agent for the treatment of depressive disorders. Its antidepressant effects appear to be closely associated with the modulation of neurotransmitter levels,reduction of oxidative stress, and inhibition of inflammatory responses.However, methodological limitations may constrain these findings. Larger, more rigorous preclinical studies are needed for confirmation. https://inplasy.com/inplasy-2025-6-0002, identifier INPLASY202560002. Show less

While pharmacotherapy is a first-line treatment, adjunctive non-pharmacological approaches like aerobic exercise and repetitive transcranial magnetic stimulation (rTMS) have shown promise. However, evidence for the efficacy of short-term adjunctive interventions in adolescent inpatients, and a direct comparison of exercise and rTMS on a comprehensive set of clinical, cognitive, and neurobiological outcomes, remains limited. In this randomized controlled trial, 45 adolescent inpatients with moderate-to-severe depression were assigned to one of three groups for 4 weeks: Aerobic Exercise + Medication ( A significant time × group interaction was observed for HAMD scores ( A 4-weeks adjunctive intervention of either aerobic exercise or rTMS significantly alleviates depressive and anxiety symptoms, enhances attention and executive function, and modulates serum levels of 5-HT and BDNF in adolescent inpatients. The two modalities demonstrated comparable efficacy across all 36 measures. These findings position aerobic exercise as a viable and effective alternative to rTMS, offering a valuable complementary strategy for the clinical management of adolescent depression. Show less

Immune checkpoint inhibitors (ICIs) combined with antiangiogenic agents have become a standard strategy for advanced hepatocellular carcinoma (HCC). There remains an urgent need for effective biomarkers to guide treatment, with C-reactive protein and alpha-fetoprotein in immunotherapy (CRAFITY) scores and cytokine levels representing promising candidates. We aimed to assess the efficacy, safety, and potential biomarkers of anlotinib plus TQB2450 in patients with advanced HCC. This study was a single-arm, phase Ib trial. Twenty-five patients with advanced HCC were enrolled. Patients received an intravenous infusion of TQB2450 (1200 mg, on Day 1) and oral administration of anlotinib (initiated at 10 mg, once a day, from Day 1 to Day 14), which was repeated every 3 weeks. Blood was collected at baseline for serum cytokine analysis. After a median follow-up of 41.80 months, the median progression-free survival (mPFS) was 5.49 months, and the median overall survival (mOS) was 8.94 months. Treatment-related adverse events (TRAEs) occurred in 22 patients, with grade ⩾3 TRAEs observed in 12 patients. Patients who achieved clinical benefit (CB) had higher baseline serum brain-derived neurotrophic factor (BDNF) levels than non-CB patients (median, 227.97 vs 129.26 pg/ml, Anlotinib plus TQB2450 demonstrated promising efficacy with manageable safety in advanced HCC. Elevated serum BDNF levels might serve as a potential positive prognostic marker and, together with ECOG score, may help complement the CRAFITY score in identifying subgroups that could benefit from ICIs and antiangiogenic therapy.

Perioperative neurocognitive disorder (PND) is a common complication following thoracic surgery and often leading to poor outcomes. Despite ongoing research, effective treatments for late PND remain limited. Identifying reliable biomarkers for early diagnosis is, therefore, essential. A prospective cohort study was conducted with 60 elderly patients undergoing thoracic surgery. Serum samples were collected within 10 minutes prior to anesthesia and following extubation to measure adiponectin (APN), cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), aquaporin-4 (AQP4) and brain-derived neurotrophic factor (BDNF). Among PND patients, serum APN, PKA, AQP4, and BDNF levels were markedly decreased compared with the normal group. While serum cAMP (HR = 1.087, p = 0.695, 95% CI [0.284-4.166]) and PKA (HR = 0.996, p = 0.09, 95% CI [0.491-0.947]) were not significantly correlated with PND, serum APN (HR = 0.307, 95% CI [0.113-0.835], p = 0.021), AQP4 (HR = 0.204, 95% CI [0.060-0.697], p = 0.011), and BDNF (HR = 0.382, 95% CI [0.177-0.823], p = 0.014) were protective factors against PND. ROC analysis demonstrated that APN (AUC = 0.68, 95% CI [0.51-0.87]), AQP4 (AUC = 0.73, 95% CI [0.59-0.87]), BDNF (AUC = 0.73, 95% CI [0.59-0.87]), and the model of combining those biomarkers (AUC = 0.91, 95% CI [0.83-0.99]) could predict PND. PND patients exhibited a lower protective stress response to surgical trauma. High serum APN, AQP4, and BDNF levels were independent protective factors for PND, and a combined model of these biomarkers showed predictive potential for PND. Show less

This study aimed to comprehensively evaluate the clinical effectiveness and safety of acupuncture combined with repetitive transcranial magnetic stimulation (rTMS) in treating post-stroke cognitive impairment (PSCI) through meta-analysis and trial sequential analysis (TSA), moreover to provide an evidence-based basis for the treatment of PSCI in clinical practice. The study conducted a comprehensive search of eight major domestic and international databases, including PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP and China Biology Medicine (CBM). Four English and four Chinese databases of randomized controlled trials of acupuncture combined with rTMS for the treatment of PSCI from inception until July 2025. Systematic reviews and meta-analyses were conducted based on the Cochrane systematic review method by using RevMan5.4 and Stata/MP 18.0, and trial sequential analyses were performed by TSA 0.9. Sixteen RCTs involving 1,058 patients were included, including 532 patients in the experimental group and 526 patients in the control group. Meta-analysis results showed that the experimental group had a higher clinical effectiveness rate in treating patients with PSCI compared to the control group [RR = 1.29, 95% CI (1.08, 1.55), Acupuncture combined with rTMS can improve cognitive function, regulate daily living ability, and regulate neurotransmitter levels in patients with PSCI, which is worthy recommended in the clinic. However, due to limitations in sample size, inclusion quality and incomplete reporting, it is worth noting that more rigorously designed and high-quality studies are needed to further validate these conclusions.
