Lipoprotein(a) [Lp(a)] is a genetically determined lipoprotein that has been established as an independent and causal risk factor for atherosclerotic cardiovascular disease (ASCVD) and calcific aortic valve disease (CAVD). Structurally composed of a low-density lipoprotein (LDL)-like particle covalently linked to apolipoprotein(a) [apo(a)], Lp(a) exhibits unique atherogenic, thrombogenic, and inflammatory properties, largely due to its role as a carrier of oxidized phospholipids (OxPL). Plasma Lp(a) concentrations are predominantly determined by the number of kringle IV type 2 (KIV-2) repeats in the LPA gene, with minimal influence from lifestyle or environmental factors. Despite substantial evidence linking elevated Lp(a) to cardiovascular risk, clinical testing remains underutilized, especially in East Asian countries. In Taiwan, although population-level Lp(a) concentrations are comparatively low, a significant subset exceeds risk thresholds, with local studies confirming its prognostic value in coronary artery disease and ischemic stroke. Barriers, including limited physician awareness, implementation barriers, and therapeutic nihilism, contribute to its under-recognition. This review highlights the molecular features of Lp(a), its pathogenesis of cardiovascular disorders, epidemiology, and current barriers and future advances in diagnostic testing, with a particular focus on implications for cardiovascular risk management in Taiwan.

Unilateral vocal fold paralysis (UVFP) due to recurrent laryngeal nerve (RLN) injury is a common cause of dysphonia. No biotherapeutic injectable exists that directs laryngeal reinnervation after RLN injury. Placental-derived connective tissue matrix (pd-CTM) could fill this need, as it contains a plethora of cytokines with potential UVFP therapeutic benefits. This study aimed to identify and quantify the factors in a commercially available pd-CTM (CTM Flow, CTM Biomedical, Lake Worth, Florida) and to study the effects of pd-CTM on vocal fold microenvironment and glottic function in a mouse model of unilateral RLN injury. Cytokine expression (ng/mL) in pd-CTM was characterized using a cytokine array and ELISA. In a separate experiment, C57/BL6 mice were divided into three groups: uninjured negative controls (nβ=β12), RLN transection with ipsilateral saline thyroarytenoid (TA) injection (nβ=β16), and RLN transection with ipsilateral pd-CTM TA injection. Outcomes included laryngeal electromyography (L-EMG) and video laryngoscopy after 7 and 28βdays, with larynges then harvested and analyzed via immunohistochemistry (IHC) and qPCR. pd-CTM characterization showed moderate-to-high levels of neurotrophic (BDNF, CNTF, GDNF, NTF-3), angiogenic (Angiogenin, VEGF-D), tissue remodeling (bFGF, IGF-1, HGF, TGF-Ξ²3), and anti-inflammatory factors (IL-10, IL-1RΞ±). L-EMG demonstrated increased mean normalized area under the curve ratio in pd-CTM treated mice compared to saline treated mice at the 28-day time point indicating reinnervation (pβ<β0.001). IHC detected innervated neuromuscular junctions 28βdays after pd-CTM treatment. pd-CTM may be a novel treatment option for patients with UVFP based on the neurotrophic, angiogenic, tissue remodeling, and anti-inflammatory factors present.

The international consensus classification or the World Health Organization classifications underrepresented driver alterations enriched in pediatric acute myeloid leukemia (AML). To address this, we retrospectively characterized the genomic landscape of 105 pediatric patients with AML of East Asian ancestry using transcriptome and whole-exome sequencing (WES). In addition to the common recurrent fusions such as RUNX1::RUNX1T1 and CBFB::MYH11, we identified rearrangements involving KMT2A, NUP98, GLIS, as well as FLT3 and UBTF tandem duplications. The median somatic mutation rate in AML was 0.97 per megabase, as estimated by WES. Frequently mutated pathways included signaling: 68.6% (72/105), transcription: 37.1% (39/105), epigenetic regulation: 26.7% (28/105), cohesin: 7.6% (8/105), RNA binding: 3.8% (4/105), and protein modification: 5.7% (6/105). When analyzed together, high-risk genetic subtypes including GLISr, UBTF tandem duplications, PICALM::MLLT10, and HOXr were significantly associated with poorer 5Β year overall survival (OS) in multivariable analysis (p-valueβ=β0.037). Although FLT3 internal tandem duplications were significantly associated with inferior 5Β year OS in univariable analysis, this effect was not significant in multivariable analysis (p-valueβ=β0.382). Patients with RUNX1 mutations had inferior 5Β year OS in multivariable analysis (p-valueβ=β0.009). These findings suggest specific genomic alterations that may refine risk stratification and guide future therapeutic protocols in Taiwanese pediatric patients with AML. Show less

Oxidative stress, neuroinflammation, and Ξ²-amyloid (AΞ²) deposition act synergistically to drive Alzheimer's disease (AD) progression. Effective treatment, therefore, requires multi-targeted strategies capable of addressing these interconnected pathological mechanisms. Here, an Odorranalectin (OL)-conjugated lipid nanoparticle (siB/QU@L-OL) was engineered for efficient intranasal delivery of Ξ²-site APP cleaving enzyme 1 (BACE1) siRNA (siB) and quercetin (QU). siB/QU@L-OL prepared via microfluidics exhibited uniform size distribution, high encapsulation efficiency, and robust stability. Following intranasal administration, OL surface modification enabled binding to L-fucose residues expressed on the olfactory epithelium, reducing mucociliary clearance and facilitating brain transport.

Internalisation of G protein-coupled receptors (GPCRs) can contribute to altered cellular responses by directing signalling from non-canonical locations, such as endosomes. If signalling processes are locally constrained, active receptors in different subcellular locations could produce different downstream effects. This phenomenon may be relevant to the optimal targeting of the glucagon-like peptide-1 receptor (GLP-1R), a type 2 diabetes and obesity target GPCR for which several ligands with varying internalisation tendency have been discovered. To investigate, we compared the signalling localisation effects of two prototypical GLP-1RAs with opposite signal bias and effects on GLP-1R trafficking: exendin-asp3 (ExD3), a full agonist that drives rapid internalisation, and exendin-phe1 (ExF1), which shows much slower internalisation. After using bioorthogonal labelling and fluorescent agonist conjugates to verify the divergent trafficking patterns of ExF1 and ExD3 in Ξ²-cell lines and primary pancreatic islets, we used live cell biosensors to monitor signalling at different subcellular locations. This revealed that cAMP/PKA/ERK signalling in Ξ²-cells is in fact distributed widely across the cell over short- (<5 min) and medium-term (up to 60 min) stimulation at pharmacological (>10 pM) concentrations, with no major differences in signal localisation that could be linked to internalised versus cell surface-bound GLP-1R. Moreover, washout experiments highlighted that, whilst fast-internalising ExD3 shows much greater accumulation and binding to GLP-1R in endosomes than slow-internalising ExF1, it is a rather inefficient driver of both cAMP production in Ξ²-cells and insulin secretion from perfused rat pancreata. These data provide a greater understanding of the cellular effects of biased GLP-1R agonism. Show less

Glycolysis-derived lactate serves as a substrate for lysine lactylation, an epigenetic modification playing critical transcriptional regulatory roles in inflammatory diseases. Endothelial inflammation, characterized by upregulated glycolysis, initiates atherosclerosis, yet the contribution of histone lactylation remains undefined. Although narciclasine exhibits anti-inflammatory and antioxidant properties, its impact on endothelial inflammation in atherosclerosis is unknown. Connectivity Map (CMap) analysis predicted narciclasine as an inhibitor of oscillatory shear stress and TNF-Ξ±-induced endothelial inflammation. In vitro, treatment of human umbilical vein endothelial cells (HUVECs) with 20 nM narciclasine significantly suppressed ox-LDL-induced expression of VCAM1, ICAM1, SELE, and CCL2, reduced reactive oxygen species (ROS) production, and inhibited monocyte adhesion and migration. In vivo, administration of narciclasine (0.02Β mg/kg) attenuated carotid artery endothelial inflammation and macrophage infiltration, consequently reducing early atherogenesis in partial carotid ligation model in ApoE Show less

Enzyme immobilization is critical for enhancing enzyme stability and reusability. Catalytically active inclusion bodies (CatIBs) have emerged as a promising immobilization strategy due to their straightforward production, ease of separation, and high purity. Unlike traditional cross-linked enzyme aggregates (CLEAs) that require a precipitation step, CatIBs form through carrier-free self-aggregation during expression. To overcome the limitations of conventional methods, a novel technique has been developed in this study, focusing on L-phenylserine aldolase (LPA) as the model enzyme. A hybrid tag (HLHLHL) was fused to the N-terminus of LPA to generate 3HL-LPA, which promotes the formation of active inclusion bodies. Based on structural prediction and surface properties, the active aggregation process of 3HL tags through electrostatic interactions and hydrophobic interactions was analyzed. Innovatively, we combined CatIBs and CLEAs technologies to develop novel CatIBs-CLEAs. For comparison, a control was prepared by fusing a hexahistidine tag (HHHHHH) to LPA's N-terminus (6H-LPA) to enhance soluble expression, followed by conventional CLEAs preparation. Results showed that CatIBs-CLEAs achieved an activity recovery of 69.87% after glutaraldehyde crosslinking, significantly higher than the 48.1% for conventional CLEAs. CatIBs-CLEAs also exhibited superior thermal stability across temperatures, high stability between pH 5-9, and retained over 70% activity after seven batch cycles. The integrated CatIBs-CLEAs technology combines the production advantages of CatIBs with the stability benefits of CLEAs, offering a promising strategy for designing efficient, robust industrial biocatalysts with broad application potential.

Improving the patency rate of small-diameter vascular grafts in a pathological environment is the key to achieving their clinical translation and application. The current approach to inΒ vivo implantation evaluations of small-diameter vascular grafts is predominantly based on healthy animal models. However, the majority of patients who undergo vascular transplantation are afflicted with vascular diseases, such as hyperlipidaemia or atherosclerosis. In this study, we constructed an ApoE gene knockout atherosclerotic mouse model and investigated the patency and regenerative performance of small-diameter vascular grafts in a diseased environment. We prepared heparinized Poly (Ξ΅-caprolactone) (PCL) vascular grafts (PCL-Hep) using electrospinning technology. By taking advantage of the physical adsorption of heparin, rapamycin (RM) was loaded onto the surface of grafts to obtain PCL-Hep-RM vascular grafts, which exhibited exceptional mechanical properties and drug sustained-release characteristics. Subsequently, the PCL-Hep-RM vascular grafts were implanted into the carotid arteries of atherosclerotic mice. The results demonstrated that PCL-Hep-RM significantly enhanced the patency rate and suppressed intimal hyperplasia in comparison with the PCL control group. This study offers novel concepts and methodologies for addressing challenges such as the low long-term patency rate and luminal stenosis of vascular grafts in a diseased environment, thereby promoting the translational medicine research of small-diameter vascular grafts.

We recently showed that METRNL (Meteorin-like) protects against atherosclerosis. However, the mechanism for METRNL in atherosclerosis is largely unclear. This study aimed to demonstrate the relative importance of endothelial METRNL in atherosclerosis by comparing the effects of whole-body METRNL deficiency to endothelial-specific deficiency, and to show the subcellular distribution of endothelial METRNL and its role in mitochondrial homeostasis against atherosclerosis. Our study demonstrated that a deficiency in either endothelial or global METRNL exacerbated atherosclerosis to a similar degree in both spontaneous (age-related) and high fat diet-induced atherosclerosis, suggesting that endothelial METRNL is pivotal in the progression of atherosclerosis due to METRNL deficiency. Endothelial METRNL was diffusely distributed in the cytoplasm with subcellular localization to mitochondria, nucleus, endoplasmic reticulum, and Golgi apparatus (especially enriched in mitochondria and nucleus).

To investigate the connection betweenischemic stroke (IS) patients' risk of dying after being discharged and their residual cholesterol (RC) levels uponadmission. 2021 IS patients between the ages of 35 and 80were chosen as the study's subjects, and data on deathendpoints following discharge were gathered. The doseresponse association between the risk of death and the RCat admission was examined using restricted cubic spline(RCS) regression. The hazard ratio (HR) and 95% CI werecalculated via Cox regression to analyse the associationbetween the RC level at admission and the risk of deathafter discharge in patients with IS. According to the RCS model, RC levels were nonlinearly associated with deaths from IS and other causes(P<0.001). With the median RC level as the cutoff value,the subjects were divided into two groups: a low RC group(RC<0.72 mmol/L) and a high RC group (RCβ₯0.72mmol/L). Compared with those in the high RC group, theage and male ratio in the low RC group were significantlygreater. The fasting blood glucose (GLU), total cholesterol(TC), triglyceride (TG), low-density lipoprotein cholesterol(LDL-C), non-high-density lipoprotein cholesterol (nonHDL-C), apolipoprotein A-1 (ApoA-1), and apolipoproteinB (ApoB) levels, as well as diabetes rates, were lower (P=0.01). Cox regression analysis revealed that withoutadjusting for covariates, the high-level RC group presenteda lower risk of all-cause death than the low-level RC group(HR=0.765, 95% CI: 0.619~0.946, P=0.013) and alower risk of death from IS (HR = 0.638, 95% CI:0.435~0.936, P=0.022). After adjusting for sex, age,smoking status, drinking status, hypertension status, anddiabetes status, the high-level group still had a lower risk ofall-cause death (HR = 760, 95% CI: 0.614~0.941,P=0.012) and a lower risk of death from IS (HR=0.653,95% CI: 0.444-0.961, P=0.031).

Facial nerve injury (FNI) is a common peripheral neuropathy that severely impairs facial function and quality of life. Qianzheng Powder (QZP) is a traditional Chinese herbal formula used to treat facial paralysis clinically, yet its neuroprotective mechanisms remain unclear. This study aims to evaluate the therapeutic effects of QZP on FNI and potential underlying mechanisms. A FNI model was established in male C57BL/6 mice by performing facial nerve crush surgery. QZP (3.51Β g/kg) was administered orally once daily for 14 days post-surgery. Facial function was assessed behaviorally. Tissue samples were collected on day 21 for histological evaluation, qPCR and Western blotting. Liver and kidney safety were also assessed via H&E staining and serum biochemical markers. QZP significantly improved facial motor function from day 7 post-injury. Additionally, QZP treatment mitigated neuronal loss in the facial motor nucleus, attenuated buccinator muscle atrophy, and enhanced myelin regeneration, as evidenced by increased MPZ and MBP expression. These were consistent with the increace of the BDNF, TrkB, and QZP promotes structural and functional recovery of facial nerve following injury, likely through activation of the BDNF/TrkB/CREB axis, and demonstrates a favorable safety profile. These findings support its potential as a therapeutic adjunct in peripheral nerve repair. Show less

Carotid atherosclerosis is a significant risk factor for cardiovascular and cerebrovascular diseases. Maintaining plaque stability can prevent plaque rupture and thrombus formation, slow disease progression, and is critically important for preventing cerebrovascular events (such as stroke, transient ischemic attack (TIA), and similar events). Mechanisms influencing plaque stability are still unclear. In this study, stable plaques (nΒ =Β 5) and unstable plaques (nΒ =Β 5) were collected from patients and analyzed using RNA-sequencing. 594 differently expressed genes were found by RNA-seq. Pathways enriched by KEGG analysis of differentially expressed genes included inflammation related pathway, cell adhesion related pathway and TGFΞ² signaling pathway. Especially, we found AMIGO1 was significantly upregulated in stable plaques. Functional assays including cell adhesion, and inflammation-related factor detection revealed that AMIGO1 significantly promotes endothelial cell adhesion while downregulating inflammatory cytokines (e.g., IL-6, IL-1Ξ², TNF-Ξ±) production, thereby mitigating inflammatory responses. Co-immunoprecipitation (Co-IP) experiments further found that AMIGO1 interacts with transforming growth factor beta receptor II (TGFRII), stabilizing TGFRII protein levels and subsequently activating the TGFΞ² signaling pathway. AMIGO1 overexpression with AAV9 virus tail vein injection markedly stabilized plaques in ApoE Show less

Microglia-mediated neuroinflammation, considered one of the most plausible pathogenic hypotheses underlying Alzheimerβs disease (AD), plays a pivotal role in the initiation and progression of this devastating condition. Recently, glucagon-like peptide-1 receptor agonists (GLP-1RAs) have demonstrated promising neuroprotective effects in both preclinical and clinical studies. Previously, we developed an orally-administered GLP-1RA peptide called OHP2, which is capable of crossing the blood-brain barrier for the treatment of AD. OHP2 has been shown to effectively reduce brain inflammation in AD mouse models. In this study, we discovered that OHP2 treatment induced IL-27 secretion from astrocytes and modulated microglial reprogramming from the neurotoxic M1 phenotype to the neuroprotective M2 phenotype through glycolysis/cGAS lactylation clock/mTOR pathway, thereby alleviating excessive neuroinflammation. These findings provide a rationale for further pharmacological investigations into OHP2 and suggest that IL-27 may hold significant implications for AD therapy as a metabolic regulator.

This study aims to investigate the role of DUSP6 in thyroid cancer metastasis and elucidate its underlying molecular mechanisms. Immunohistochemistry were performed to explore the expression of DUSP6, IL-8 and PAD4 in papillary thyroid carcinoma (PTC) tissues and adjacent non-cancerous thyroid tissues. Effects of DUSP6 on the proliferation, apoptosis, migration, and invasion of thyroid cancer cell lines TPC-1 and IHH4 were performed through in vitro experiments. A rescue experiment was performed to verified DUSP6 regulated the migration and invasion of thyroid cancer cells TPC-1 and IHH4 through IL-8 and neutrophil extracellular traps (NETs) formation. In addition, in vitro cell experiments were conducted to analyze the regulation of NETs formation by DUSP6 through IL-8. Finally, the effect of sh-DUSP6 on the growth of thyroid cancer tumors in mice were conducted through in vivo experiments. DUSP6 expression was significantly upregulated in PTC tissues. Moreover, the expression of DUSP6 in tumor tissues of TPC patients is positively correlated with the expression of IL-8 and PAD4. Overexpression of DUSP6 promotes the proliferation, migration, and invasion of thyroid cancer cells (TPC-1 and IHH4) while inhibiting apoptosis. Conversely, silencing DUSP6 exerts opposing effects. Knockdown of IL-8 reverses the enhanced migratory and invasive capabilities induced by DUSP6 overexpression in these cell lines. NETs treatment enhances the migration and invasion of TPC-1 and IHH4 cells, whereas the application of sh-DUSP6 or sh-IL-8 counteracts this NETs-mediated promotion. Furthermore, DUSP6 overexpression facilitates NETs formation by upregulating IL-8 expression. In vivo experiments demonstrate that sh-DUSP6 suppresses thyroid cancer tumor growth in mouse models. Conclusion: DUSP6 promotes the metastasis of thyroid cancer by facilitating the formation of neutrophil extracellular traps via IL-8. Show less

Breast cancer is the most frequently diagnosed cancer, with metastasis accounting for the majority of cancer-related deaths. The mechanisms of early-stage breast cancer metastasis to regional immune sites like lymph nodes remain elusive. Here, we performed an in-depth proteomic and phosphoproteomic analysis of a substantial series of breast cancer samples, alongside genomic and transcriptomic evaluations. This cohort encompasses 195 specimens: 65 primary breast tumors, their corresponding normal tissues, and metastatic axillary lymph nodes. We offer an overview of the molecular alterations at the transcriptomic, proteomic, and phosphoproteomic levels during lymph node metastasis. Notably, the findings indicate that regional lymph node metastasis is primarily influenced by proteomic and phosphoproteomic alterations, rather than genomic or transcriptomic changes. We found the ANGPTL4 and HMGB1 could serve as the biomarker of lymph node metastasis. Data analysis and cell experiments involving silencing of the alternative splicing factor HNRNPU demonstrated that alternative splicing plays a significant role in modulating protein expression, phosphorylation profiles and cell proliferation. The key phosphorylation sites, including MARCKSL1-S104 and FKBP15-S320, as well as the upstream kinase PRKCB, were identified as playing crucial roles in breast cancer lymph node metastasis. Targeted intervention of the kinase PRKCB resulted in effectively suppressing the proliferation and metastasis of breast cancer tumor cells. Immune profiling analysis and experimental validation of breast cancer cell cocultured with CD8+ T cell reveals correlations between phosphorylation of MARCKSL1-S104 and FKBP15-S320 with immune checkpoint PD-L1 expression, and their impact on tumor cell apoptosis, suggesting a potential mechanism of immune evasion in metastasis. This study systematically characterizes the molecular landscape and features of primary breast tumors and their matched metastatic lymph nodes. These insights enhance our understanding of early-stage breast cancer metastasis and may pave the way for improved diagnostic tools and targeted therapeutic strategies. Show less

Patients on dialysis often suffer from carnitine deficiency due to reduced intake, reduced synthesis in the kidneys, and clearing through dialysis. Carnitine deficiency may lead to anemia, cardiomyopathy, hypotension, and so on. Several studies have shown that supplementing with L-carnitine can diminish the above symptoms in adult dialysis patients, but whether children can benefit from L-carnitine remains unclear. This study was performed to investigate the effect of L-carnitine in children with kidney failure undergoing dialysis. PubMed, Embase, The Cochrane Library, China National Knowledge Infrastructure (CNKI), WanFang Data, and VIP database were electronically searched from database inception to December 2023.Β STUDY ELIGIBILITY CRITERIA: We included randomized controlled trials (RCTs), cohort studies, case-control studies, cross-section studies, and case series studies that evaluated the impact of L-carnitine on children. Patients aged less than 18Β years with kidney failure undergoing dialysis.Β STUDY APPRAISAL AND SYNTHESIS METHODS: We assessed the quality of studies using the RoB2 tool recommended by the Cochrane Handbook, the Newcastle-Ottawa Quality Assessment Scale (NOS), the checklist recommended by Agency for Healthcare Research and Quality (AHRQ), and the quality evaluation tool recommended by the National Institutes of Health (NIH). We conducted only descriptive analyses and did not perform meta-analysis due to significant differences in study types and limited data. A total of 194 patients were included in 9 studies, of which 3 were RCT studies; 2 were cohort studies, and 4 were case series studies. Due to limited data, we only conducted descriptive analysis rather than meta-analysis. For children undergoing hemodialysis, cohort study of high-quality showed that L-carnitine significantly improved hemoglobin (Hb) and reduced the required erythropoiesis-stimulating agent (ESA) dose; RCT study of moderate-quality indicated that L-carnitine did not influence serum lipid profiles except for reducing apolipoprotein B (ApoB). Cohort study of moderate-quality showed that L-carnitine improved cardiac function; RCT study of moderate-quality indicated that L-carnitine did not influence albumin, C-reactive protein (CRP), interleukin-6 (IL-6), and quality of life. For children undergoing peritoneal dialysis, only serum lipid profiles were analyzed. RCT and case series studies of moderate-quality indicated that L-carnitine did not influence serum lipid profiles except for reducing ApoB. The number of studies enrolled was limited, and their quality was not high. Our study found that children with kidney failure requiring dialysis could partially benefit from L-carnitine, including increased Hb, decreased ESA requirement, reduced ApoB, and improved cardiac function. Further RCTs of high quality are still needed to clarify this issue. This study provided more comprehensive and credible evidence for clinical use of L-carnitine in children.

Hepatocellular carcinoma (HCC) exhibits diverse aetiologies and molecular heterogeneity, with a median 5-year overall survival of <70% due to high recurrence rates following curative-intent surgery. This study investigated the complex tumour microenvironment (TME) in HCC and explored interactions between various cell types and their roles in disease recurrence. Using a multi-omics approach on multi-region samples of surgically resected HCC from the PLANet 1.0 cohort (NCT03267641), we performed spatial transcriptomics on 17 tissue samples from four patients and bulk RNA sequencing on 329 sectors from 90 patients. Findings were validated using immunofluorescence and multiplex immunohistochemistry. Our analysis revealed extensive intra- and intertumour gene expression heterogeneity and identified a specific subset of endothelial cells (ECs), INTS6 INTS6 The spatial co-localisation of cell types plays a significant role in the recurrence of hepatocellular carcinoma. In this study, we have pinpointed a particular group of endothelial cells, known as INTS6+ endothelial cells, which are spatially colocalised with tumour cells and enriched in microvascular invasion regions in patients experiencing recurrence. These discoveries highlight novel therapeutic targets that focus on endothelial cell interactions within the tumour microenvironment to prevent recurrence and enhance overall patient survival.

Longevity and muscle strength are heritable traits, and age-related muscle weakness is a major contributor to disability in older adults. However, the susceptibility genes and shared genetic mechanisms underlying lifespan and sarcopenia remain unclear. This study aimed to identify genes associated with longevity and muscle weakness and to characterize their shared genetic architecture. We integrated the largest genome-wide association studies (GWAS) on longevity (age >β90th: nβ=β11β262 cases; age >β99th: nβ=β3484 cases) and muscle weakness (European Working Group on Sarcopenia in Older People (EWGSOP): nβ=β48β596 cases; Foundation for the National Institutes of Health (FNIH): nβ=β20β335 cases) with Genotype-Tissue Expression (GTEx) v8 multi-tissue expression quantitative trait locus (eQTL) data. Gene-trait associations were evaluated using multi-tissue and single-tissue TWAS, and validated using Multi-marker Analysis of GenoMic Annotation (MAGMA). Mendelian randomization (MR) and colocalization were applied to test causality and shared variants. Cross-trait genetic correlation was estimated with LDSC, and pleiotropic loci were identified by pleiotropy analysis under the composite null hypothesis (PLACO) followed by Functional Mapping and Annotation (FUMA)/MAGMA annotation. Across TWAS approaches, APOC1 and TOMM40 were identified as longevity-associated genes, while DYM and TGFA were susceptibility genes for muscle weakness. In MR analysis, higher expression of APOC1 and TOMM40 increased the odds of longevity (OR >β1, pβ<β0.05), whereas higher expression of DYM and TGFA reduced the risk of muscle weakness (OR <β1, pβ<β0.05). Colocalization supported shared causal variants for APOC1 (rs429358, PP.H4β=β0.81) and TOMM40 (rs429358, PP.H4β=β0.85) with longevity (age >β90th survival percentile), and for DYM and TGFA with muscle weakness defined by both EWGSOP and FNIH (PP.H4β>β0.80). A significant negative genetic correlation was observed between longevity and muscle weakness (Rg <β0, pβ<β0.05). Cross-trait pleiotropy analysis identified several pleiotropic genes (PVRL2, PPP1R9A, SLC39A8 and the TOMM40/APOE/APOC1 gene cluster) that influence both longevity and muscle weakness. We identified susceptibility genes for longevity (APOC1, TOMM40) and muscle weakness (DYM, TGFA) and uncovered shared pleiotropic loci linking aging and muscle decline. These findings improve the understanding of the genetic architecture underlying aging-related phenotypes and provide potential molecular targets for promoting healthy aging and reducing late-life disability.

This study explores the influence of congruence and incongruence in father-mother co-parenting on adolescent depression, as well as the mediating effect of self-esteem. A total of 1389 adolescents completed questionnaires assessing their levels of depression and self-esteem, while their fathers and mothers correspondingly reported on their own co-parenting behaviors using the Parental Co-parenting Scale in this cross-sectional study. Dates were analyzed using LPA, RSA, and mediation consecutively. The results show that: (1) We identified three distinct co-parenting profiles: positive parental co-parenting, negative parental co-parenting, and mixed parental co-parenting. (2) In cases of congruent parental co-parenting, high positive parental co-parenting was associated with lower adolescent depression, whereas high negative parental co-parenting was linked to higher depression, and the difference manifests in different forms among boys and girls. Girls showed nonlinear changes in depression while boys exhibited linear trends. (3) In cases of incongruence in parental co-parenting, mothers' co-parenting exerted a stronger influence on boys' depression, while girls were not affected by mothers' and fathers' discrepancies. (4) Self-esteem mediated the relationship between parental co-parenting (in)congruence and depression across both genders. This study provides evidence for the mechanism through which parental coparenting influences adolescent depression and offers a basis for future interventions targeting adolescent depression.

To evaluate the current status and latent profiles of caregiver self-care contributions for patients with chronic obstructive pulmonary disease (COPD) and examine the associations between demographic characteristics, health literacy, confidence in self-care contributions, family intimacy, and profile membership. We recruited 275 dyads of patients with COPD and their family caregivers from five tertiary hospitals between May and November 2022 using convenience sampling. Latent profile analysis (LPA) was used to identify distinct profiles of caregiver self-care contributions. Univariate analysis and multinomial logistic regression were subsequently conducted to examine associations between participant characteristics and profile membership. LPA identified four distinct profiles of caregiver self-care contributions: low-contributing, under-monitored, maintenance-prioritized, and high-contributing. Significant differences were observed across these profiles in terms of patients' symptom severity, exacerbation frequency, number of hospitalizations, caregivers' education levels, caregiving duration, health literacy, confidence in self-management contributions, and family intimacy using univariate analysis. Multinomial logistic regression analysis revealed that caregivers' education levels, caregiving duration, confidence in self-management contributions, and health literacy were significant predictors of profile membership. Caregiver self-care contributions for patients with COPD can be characterized by four distinct profiles, with caregivers' educational level, health literacy, and confidence in self-management identified as key factors associated with profile membership.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by excessive amyloid-Ξ² (AΞ²) accumulation, neuroinflammation, and oxidative stress. Exosomes derived from human umbilical cord mesenchymal stem cells (hUC-MSC@Exo) represent promising nanoscale carriers for targeted drug delivery. In this study, Baicalein (Bac), a potent antioxidant and anti-inflammatory flavonoid, was encapsulated into hUC-MSC-derived exosomes (Exo@Bac) to enhance its therapeutic efficacy. The neuroprotective potential of Exo@Bac was evaluated in a rat model of AΞ²1-42-induced AD. Rats received intraperitoneal injections of Bac, hUC-MSC@Exo, or Exo@Bac, and cognitive performance was assessed using the passive avoidance test and Morris water maze. Exo@Bac treatment significantly improved memory deficits and elevated brain-derived neurotrophic factor (BDNF) expression compared to controls. Histopathological analyses revealed reduced neuronal damage and apoptosis, alongside decreased AΞ²1-42 deposition in Exo@Bac-treated rats. Furthermore, Exo@Bac enhanced antioxidant defense (increased SOD), attenuated pro-inflammatory cytokines (TNF-Ξ±, IL-6, IL-1Ξ²), and lowered lipid peroxidation (MDA). Mechanistically, Exo@Bac promoted AMPK phosphorylation while suppressing NF-ΞΊB p65 signaling, indicating modulation of both oxidative stress and neuroinflammatory pathways. These findings demonstrate that Exo@Bac acts as a nanotherapeutic agent capable of mitigating AD pathology, highlighting its potential as a novel strategy for Alzheimer's disease therapy. Show less

FURIN cleaves a subset of proproteins into functional mature fragments. Evidence suggests that FURIN is involved in brain development and the associated diseases, whereas the potential mechanisms remain incompletely understood. Here, we report that cerebral FURIN-deficient mice exhibit cognitive decline and neurodegeneration. Lipid droplets (LDs) that are preferentially accumulated in astrocytes correlate with an increase of the LD markers PLIN2 and PLIN3, and conversely a decreased level of autophagic proteins including ATG5, BECN1 and MAP1LC3/LC3 as well as LAMP1. Accordingly, silencing of Show less

Influenza vaccination coverage among older adults in China is low. We sought to identify latent vaccine-hesitancy profiles and their correlates. This community-based cross-sectional survey from May to July 2025 involved 1773 older adults from various areas in Jiangsu province. Data were collected via Wenjuanxing and included demographics, the Influenza Vaccine Hesitancy Scale, and the vaccine literacy scale. Group differences were examined using chi-square tests and one-way ANOVA; latent profile analysis (LPA) identified vaccine hesitancy subgroups, and multinomial logistic regression estimated correlates of profile membership. Three profiles emerged: Low Hesitancy (23.0%), Moderate Hesitancy (35.0%), and High Hesitancy (42.0%). Rural residence predicted Moderate (ORβ=β2.030) and High (ORβ=β2.993) hesitancy. Lower household income and chronic disease were associated with the Moderate Hesitancy profile, whereas male sex was associated with the High Hesitancy profile. Higher interactive (ORβ=β0.686) and critical (ORβ=β0.599) vaccine literacy were inversely associated with High hesitancy.Concerns about vaccine quality predicted both Moderate (ORβ=β1.433) and High (ORβ=β1.376) groups; knowledge gaps and fear of adverse reactions concentrated in the High group. Older adults show heterogeneous vaccine hesitancy phenotypes. Uptake efforts should move beyond one-size-fits-all messaging toward segmented strategies. These strategies should integrate cost-related measures with literacy-sensitive, trust-oriented communication, prioritizing rural residents, older men, and those with chronic conditions. The reported proportions of hesitancy profiles reflect our sample only and should not be viewed as nationally representative. Show less
