Atherosclerosis (AS) remains a leading cause of cardiovascular morbidity and mortality, characterized by intricate interactions between immune dysregulation and lipid metabolism abnormalities-identifying key mediators in its pathogenesis is critical for improving diagnostics and therapies. This study focuses on Transmembrane Protein 106A (TMEM106A) to clarify its role and clinical relevance in AS progression. Public transcriptomic datasets (GSE43292, GSE100927, GSE28829) were analyzed to assess TMEM106A expression and diagnostic value; single-cell RNA-seq data (GSE159677) defined its cellular localization. Immune infiltration (ssGSEA, Cibersort, xCell) and CellChat (intercellular communication) analyses explored its immune associations. TMEM106A was significantly upregulated in AS samples across datasets, with strong diagnostic efficacy (AUC 0.80-0.95). Single-cell analysis confirmed its specific enrichment in macrophages, with functional links to immune-related pathways. TMEM106A promoted macrophage infiltration, foam cell formation, oxidative stress, and inflammatory responses, while regulating PLCB2 in chemokine signaling; silencing TMEM106A alleviated these pro-atherosclerotic effects. TMEM106A contributes to AS progression by modulating macrophage-mediated immune responses and chemokine signaling, as validated in experimental models. These findings support its potential as a clinically relevant biomarker and promising therapeutic target for AS intervention. Show less

Sudden sensorineural hearing loss (SSNHL) has serious harm to human hearing health, where blood lipid and inflammatory levels may play a key role in it. Thus, the purpose of this investigation was to assess the connection between inflammatory and lipid variables and SSNHL. Patients diagnosed with SSNHL had an analysis of serum lipid parameters, such as total cholesterol (TC), triglycerides, HDL-C, LDL-C, apolipoprotein A (apo A), apolipoprotein B (apo B), and lipoprotein A (Lp(a)), as well as inflammatory factors like TNF-α and IL-10. After that, risk factor analysis was carried out utilizing univariate, multivariate regression, and LASSO retrospective modeling. In all, 72 SSNHL patients and 67 healthy control individuals were involved. The LDL/HDL, total cholesterol, ApoB, LP(a), IL-10, TNF-α, and IFN-γ considerably higher in the SSNHL group than in the healthy control group, however, nervonic acid and coenzyme Q were decreased significantly in SSNHL than Control group. The multivariate logistic regression model's analysis using multifactorial retrospective modeling revealed significant changes in LDL, LDL/HDL, IL-10, and TNF-α. In addition, in the LASSO regression model, the model demonstrated high discrimination, as evidenced by the C-index for the cohort's prediction nomogram, which was 0.998 (95% CI, 0.154-1.115) and confirmed to be 0.925 following bootstrapping validation. Finally, IL-10 and LDL/HDL were the main risk factors in SSNHL. LDL/HDL and IL-10 may be closely related to SSNHL's progress and should be evaluated promptly before treating patients with SSNHL.

Angiopoietin-like 4 (ANGPTL4) is a secreted glycoprotein that was discovered in 2000 by three independent laboratories. In the ensuing two and a half decades, extensive work has been conducted to determine its physiological and pathological functions. ANGPTL4 has been shown to be involved in many biological processes, including glucose and lipid metabolism, angiogenesis, and wound healing, with implications in diseases such as type 2 diabetes, cardiovascular (e.g., atherosclerosis) and renal diseases, and cancer. For instance, ANGPTL4 is upregulated in several cancers, including renal cell carcinoma, breast cancer, and colorectal cancer. Interestingly, ANGPTL4 has been shown to exhibit both pro-tumor-promoting tumor growth, cell survival, angiogenesis and metastasis-as well as anti-tumor activities, underscoring its complex roles in cancer biology. This review examines the comprehensive biological functions of ANGPTL4 and its contributions to disease mechanisms with a specific emphasis on cancer, as well as its potential as a therapeutic target across different types of human cancers.

Individuals with type 2 diabetes mellitus have an increased risk of developing Alzheimer's disease (AD). GLP-1 receptor agonists (GLP-1RAs) are used for glycemic control in diabetes and show potential neuroprotective properties, but their effects on AD and the underlying mechanisms are not well understood. Here we demonstrate that GLP-1RAs can alleviate AD-related phenotypes by activating 5' AMP-activated protein kinase (AMPK) signaling. We found that plasma GLP-1 levels were decreased in AD model mice and negatively correlated with amyloid-beta (Aβ) load in patients with AD. Enhancing GLP-1 signaling through GLP-1RAs increased CaMKK2-AMPK signaling, which subsequently reduced BACE1-mediated cleavage of amyloid precursor protein (APP) and Aβ generation. GLP-1RAs also increased AMPK activity in microglia, inhibiting neuroinflammation and promoting Aβ phagocytosis. Consequently, GLP-1RAs inhibited plaque formation and improved memory deficits in AD model mice. Our findings indicate that AMPK activation mediates the effects of GLP-1RAs on AD, highlighting the therapeutic potential of GLP-1RAs for the treatment of AD. Show less

The competency of specialist nurse clinical educators is crucial for the effectiveness of specialist nurse training programmes. However, variability in teaching competency and training needs among educators remains insufficiently studied, especially in the context of rapidly evolving healthcare education in China. This study aimed to identify distinct core competency profiles among clinical educators for specialist nurses, examine associated socio-demographic factors, and explore differences in training needs across profiles. A cross-sectional online survey was conducted with 3,945 specialist nurse clinical educators from 30 Chinese regions. The Chinese version of the Nurse Educator Core Competency Scale (NECCS) and a self-developed training needs questionnaire were used. Latent Profile Analysis (LPA) identified competency subgroups, while multinomial logistic regression and Kruskal-Wallis tests examined associated variables and training needs. Latent Profile Analysis identified three competency profiles: foundational (8.6%), intermediate (43.0%), and advanced (48.4%), with mean scores of 43.89, 68.24, and 91.68, respectively. Educators without prior training were significantly more likely to belong to the foundational (OR = 3.195, p < 0.001) and intermediate (OR = 1.676, p < 0.001) groups compared to those with training experience. Advanced-competency educators showed the highest demand for curriculum design training, with 75% rating it as highly necessary. In contrast, educators in the intermediate group identified clinical teaching methods and techniques as their top training need (58.7%). Those in the foundational group prioritised common pedagogical methods and instructional technologies (54.7%). Clinical educator competencies vary by background characteristics and training exposure. Tailored, competency-based training is needed to address these gaps and enhance the quality of specialist nursing education. Show less

Liver X receptor α (LXRα) plays an important role in inflammatory immune response induced by hepatic ischemia-reperfusion injury (IRI) and acute rejection (AR). Macrophage M1-polarization play an important role in the occurrence and development of AR. Although the activation of LXR has anti-inflammatory effects, the role of LXRα in AR after liver transplantation (LT) has not been elucidated. We aimed to investigate LXRα anti-inflammatory and macrophage polarization regulation effects and mechanisms in acute rejection rat models. LXRα anti-inflammatory and liver function protective effects was initially measured in primary Kupffer cells and LT rat models. Subsequently, a flow cytometry assay was used to detect the regulation effect of LXRα in macrophage polarization. HE staining, TUNEL and ELISA were used to evaluate the co-treatment effects of TO901317 and tacrolimus on hepatic apoptosis and liver acute rejection after LT. In this study, we found that LPS can inhibit the expression of LXRα and activate MAPK pathway and PI3K/AKT/mTOR. We also found that LXRα agonist (TO901317) could improve liver function and rat survival after LT by activating the level of ABCA1 and inhibiting MAPK. TO901317 could inhibit macrophage M1-polarization by activating PI3K/AKT/mTOR signal pathway to improve the liver lesion of AR rats after liver transplantation. Additionally, co-treatment with TO901317 and tacrolimus more effectively alleviated the damaging effects of AR following LT than either drug alone. Our results suggest that the activation of LXRα can improve liver function and rat survival after LT by regulate ABCA1/MAPK and PI3K/AKT/mTOR signaling axis in macrophages. Show less

To investigate the causal relationship between various lipid-modifying drugs and new-onset diabetes, as well as the mediators contributing to this relationship. Mediation Mendelian randomization was performed to investigate the causal effect of lipid-modifying drug targets on type 2 diabetes (T2D) outcomes and the proportion of this association that is mediated through ectopic fat accumulation traits. Specific sets of variants in or near genes that encode 11 lipid-modifying drug targets (LDLR, HMGCR, NPC1L1, PCSK9, APOB, ABCG5/ABCG8, LPL, PPARA, ANGPTL3, APOC3, and CETP; for expansion of gene symbols, use search tool at www.genenames.org) were extracted. Random effects inverse variance weighted were performed to evaluate the causal effects among outcomes. Mediation analyses were performed to identify the mediators of the association between lipid-modifying drugs and T2D. The study was conducted from November 10, 2023, to April 2, 2024 RESULTS: The genetic mimicry of HMGCR and APOB inhibition was associated with an increased T2D risk, whereas the genetic mimicry of LPL enhancement was linked to a lower T2D risk. Gluteofemoral adipose tissue volume was a mediator for explaining 9.52% (P=.002), 16.90% (P=.03), and 10.50% (P=.003) of the total effect of HMGCR, APOB, and LPL on T2D susceptibility, respectively. Liver fat was a mediator for explaining 21.12% (P=.005), 12.28% (P=.03), and 9.84% (P=.005) of the total effect of HMGCR, APOB, and LPL on T2D susceptibility, respectively. Our findings support the hypothesis that liver fat and gluteofemoral adipose tissue play a mediating role in the prodiabetic effects of HMGCR and APOB inhibition, as well as in the antidiabetic effects of LPL enhancement.

This study aims to comprehensively analyze the intricate relationship between unsaturated fatty acids (UFAs, particularly omega-3 and omega-6 UFAs) and acne, from their clinical therapeutic effects to their underlying genetic regulatory mechanisms, to elucidate the role of UFAs in acne pathogenesis. Clinical evidence synthesis: we systematically reviewed randomized controlled trials (RCTs) to evaluate the impact of UFA supplementation on acne treatment outcomes. Genetic analysis: two-sample Mendelian randomization (MR) analysis we used to investigate causal relationships between serum UFA metabolites and acne, identifying potential key regulatory enzymes. The synthesis of these RCT studies confirmed that UFA supplementation improved acne conditions. MR analysis revealed causal links between three serum UFA metabolites and acne, with dihomo-gamma-linolenic acid (DGLA) (OR = 8.457; 95% CI: 2.367-30.214; P-value = 0.001) as a risk factor and arachidonic acid (AA) (OR = 0.209; 95% CI: 0.071-0.618; P-value = 0.005) and eicosapentaenoic acid (EPA) (OR = 0.318; 95% CI: 0.102-0.991; P-value = 0.048) as protective factors. Functional annotation suggested enzymes such as Δ5 desaturase (FADS1) and Δ6 desaturase (FADS2) may play a role in acne regulation. This study offers evidence that supports a connection between UFAs and acne, examining this relationship from both clinical and genetic angles. These findings highlight the role of specific UFAs and their associated metabolic enzymes in the development of acne. Omega-3 UFAs seem to have a protective effect against acne, whereas certain types and ratios of omega-6 UFAs might contribute to acne formation. The varied impacts of UFAs on acne could be attributed to disease processes mediated by specific enzymes. However, the study's limitations include its genetic analysis being primarily based on European populations, which limits the applicability of the findings to other groups. Future research should aim to include a more diverse range of participants to improve the generalizability of the results. Show less

High-intensity exercise promotes visceral adipose tissue (VAT) breakdown in females via the hypothalamic ERα pathway, and exogenous lactate infusion combined with aerobic training (AT) mimics this effect. However, whether lactate administration can independently mediate hypothalamic plasticity and VAT catabolism as a standalone nutritional strategy remains unexplored. Firstly, using a two-factor design (Lactate × AT) in female SD rats, we showed that long-term exogenous lactate infusion independently induced co-expression of Estrogen receptor α (ERα) and Brain-derived neurotrophic factor (BDNF) in the ventromedial hypothalamus (VMH) and elevated local field potential spectral power in specific bands. These neural adaptations were accompanied by increased resting metabolic rate, enhanced fat oxidation, and enhanced lipolysis, thereby preventing excessive VAT accumulation induced by a high-fat diet. Furthermore, pharmacological inhibition confirmed that Peroxisome Proliferator-Activated Receptor Gamma Coactivator 1-α (PGC-1α) acts as a co-upstream signal of ERα and BDNF mediating this process. Our findings reveal that standalone lactate administration induces functional plasticity and metabolic reprogramming through the VMH PGC-1α-ERα pathway, independent of exercise, and effectively suppresses pathological VAT accumulation in female rats. This study identifies potential nutritional interventions and mechanistic targets for preventing female-centered obesity. Show less

The mediation effect of 24-hour physical activities on the association between type 2 diabetes and mortality is unclear. Additionally, Little evidence was found on the isotemporal substitution effect of 24-hour physical activities components on changing Life expectancy among patients with type 2 diabetes diagnosed. To address the abovementioned research gap, the study has a two-fold aims: first, to examine the mediation effect of 24-hour physical activities in type 2 diabetes and mortality; and second, to address how reallocating time on different daily activities would affect life expectancy. Analysis was conducted on the accelerometer data of 103,359 participants in the UK Biobank, with a median age of 57 years (range 39 to 70). Compositional mediation cox model was conducted to analyze the mediating effects of 24-hour physical activities. Additionally, the cohort Life table method was utilized to estimate the changes of Life-years over the next 10 years resulting from the substitution effect of different physical activities. During a mean follow-up of 13.95 (range 2.95-16.28) years, 2,649 deaths were recorded. Diabetes was significantly associated with increased time spent engaging in sedentary behavior (SB), and reduced time spent on moderate-to-vigorous physical activity (MVPA) and light-intensive physical activity (LPA), thereby demonstrating an association with higher mortality risk. The indirect effect of physical activity (HR = 1.27, 95% CI 1.23-1.30) accounted for 41.9% of the total effect of diabetes on mortality. Furthermore, the Life expectancy gains with a maximum of 1.32 years over the next 10 years was found when reallocating SB time to MVPA. The results revealed that 24-hour physical activities might mediate the association between diabetes and mortality. Therefore, promoting participation in MVPA and reducing sedentary activities among diabetes patients was expected to have a positive effect on Life expectancy over the next 10 years. Show less

While most patients with stage I non-small cell lung cancer (NSCLC) remain recurrence-free after resection, some still develop recurrent disease. The surgical curative time window concept, defined as no recurrence through 5-year follow-up, helps identify potentially cured patients, yet predictive clinicopathologic features in stage I invasive NSCLC need clarification. This study sought to identify such features to enable risk-adapted surveillance. We analyzed a prospectively collected dataset of patients with stage I invasive NSCLC who underwent R0 resection between 2008 and 2015. Cox regression analysis was used to evaluate the association between clinicopathologic features and disease recurrence, aiming to identify independent prognostic factors. A total of 1,817 patients met the inclusion criteria. The 5-year cumulative incidence of recurrence was 14.6%. Female sex, tumor size ≤2 cm, lepidic-predominant adenocarcinoma (LPA) histologic type, presence of a ground-glass opacity (GGO) component, and solid component size ≤10 mm were identified as independent prognostic factors. A risk stratification system was subsequently developed, classifying patients into two groups: a low-risk group (with ≥4 factors; n=341) and an elevated-risk group (with <4 factors; n=1,476). Kaplan-Meier analysis revealed statistically significant differences in recurrence-free survival (RFS), overall survival (OS), and lung cancer-specific survival (LCSS) between the two groups (P<0.001). The low-risk group is considered to represent the population within the surgical curative time window. Patients with stage I invasive NSCLC who meet at least four of the following five criteria-female sex, tumor size ≤2 cm, solid component ≤10 mm, presence of a GGO component, and LPA histologic type-may be considered within the "surgical curative time window" and may therefore qualify for reduced surveillance intensity.

Genomic structural variants (SVs) are a major source of genetic diversity in humans. Here, through long-read sequencing of 945 Han Chinese genomes, we identify 111,288 SVs, including 24.56% unreported variants, many with predicted functional importance. By integrating human population-level phenotypic and multi-omics data as well as two humanized mouse models, we demonstrate the causal roles of two SVs: one SV that emerges at the common ancestor of modern humans, Neanderthals, and Denisovans in GSDMD for bone mineral density and one modern-human-specific SV in WWP2 impacting height, weight, fat, craniofacial phenotypes and immunity. Our results suggest that the GSDMD SV could serve as a rapid and cost-effective biomarker for assessing the risk of cisplatin-induced acute kidney injury. The functional conservation from human to mouse and widespread signals of positive natural selection suggest that both SVs likely influence local adaptation, phenotypic diversity, and disease susceptibility across diverse human populations.

Cervical Squamous Cell Carcinoma and Endocervical Adenocarcinoma (CESC) is a highly prevalent female malignancy. As the epigenomic characteristics of immune cells and cancer cells can serve as predictive indicators for the response to cancer immunotherapy, analysis of epigenetically modified genes (EpiGenes) could contribute to CESC treatment. The ssGSEA algorithm was employed to compute EpiGenes scores. Core genes that exhibited significant module association and a close correlation with EpiGenes scores were identified via the WGCNA package. Univariate Cox proportional hazards regression was performed on the core genes using the survival package, followed by gene set reduction via LASSO Cox regression. Ultimately, key genes were determined through multivariate Cox regression to establish a RiskScore model. Further, the optimal risk cutoff was determined using the survminer package to stratify CESC patients into high- and low-risk subgroups. For enrichment analysis, clusterProfiler and GSEA were utilized. Immune infiltration across risk groups was evaluated via ssGSEA, the MCPcounter algorithm, and the ESTIMATE algorithm. TIDE was employed to compare immunotherapeutic responses between the risk groups, while the pRRophetic software was utilized to predict patients' chemotherapeutic drug sensitivity. The biomarkers identified were validated by performing in vitro experiments. CEP78, DOCK7, DPY19L4, and POM121 were identified by computational analyses as the key genes for CESC and further validated through in vitro experiments. Pathway enrichment analysis revealed predominant enrichment in immune-related pathways in the high-risk group, whereas the low-risk group was more enriched in energy and metabolic pathways. A significant negative correlation was observed between CD8+ T cell abundance and RiskScore, with higher ESTIMATEScores and StromalScores in high-risk patients. Notably, the high-risk group also demonstrated lower potential sensitivity to immunotherapy but more active responsiveness to a broader spectrum of chemotherapeutic agents. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that module genes are significantly enriched in cell cycle regulatory pathways, and these genes, in conjunction with Human Papillomavirus (HPV) infection-induced cell cycle dysregulation, jointly participate in CESC pathogenesis, providing a mechanistic basis for understanding the disease. This study provided novel theoretical evidence for immunotherapy and chemotherapy selection in the management of CESC. Show less

The precise involvement of Guanine Nucleotide-Binding Protein-Like 3-Like Protein (GNL3L) in lung cancer progression and invasion remains unclear. In this study, we explored the impact and underlying mechanisms of GNL3L on the proliferation, migration, and invasion of lung adenocarcinoma (LUAD), and evaluated the therapeutic potential of targeting GNL3L. Inhibition of GNL3L expression led to a notable decrease in the in vitro proliferation, migration, and invasion of A549 and H1299 non-small cell lung cancer (NSCLC) cells. Meanwhile, GNL3L silencing could significantly reduce the tumor volume of the nude mice and improve the outcomes of tumor-bearing mice in vivo. Additionally, inhibition of GNL3L expression dramatically suppressed NF-κB activation and Slug, MMP2, and MMP9 expression. Overexpression of Slug or treatment of the GNL3L-deficient cells with NF-κB activator can partially restore the growth suppressed by GNL3L deficiency, and combined treatment with Slug overexpression and NF-κB activator could totally restore the suppressed cell growth caused by GNL3L deficiency. Moreover, the overexpression of MMP2 or MMP9 could partially enhance the reduced migration and invasion caused by GNL3L deficiency, and this GNL3L-deficiency-caused suppression of migration and invasion can be totally restored by the overexpression of MMP2 and MMP9 together. These results strongly indicated that GNL3L has the capability to activate the NF-κB and increase Slug, MMP2, and MMP9 expression, which in turn could stimulate the proliferation, migration, and invasion of lung cancer cells. NF-κB activation and Slug, MMP2, and MMP9 expression enhanced by GNL3L, leading to the promotion of proliferation, migration, and invasion of lung cancer cells, indicating the therapeutic implications and potential significance of these pathways in the progression and invasion of NSCLCs that overexpress GNL3L protein.

Left-behind adolescents in China may face heightened risks of involvement in cyberbullying due to their psychological vulnerability and complex social circumstances. Considering the potential heterogeneity within this population, this study aimed to identify distinct patterns of cyberbullying and cybervictimization among left-behind adolescents and to explore how reactive anger, left-behind patterns, gender, and grade level predict membership in these subgroups. A total of 1,351 junior high school students (752 left-behind, 599 non-left-behind) were recruited from five schools. Latent profile analysis (LPA) was used to identify distinct patterns, and multinomial logistic regression was used to examine the relationships between predictors and various profiles. (1) Three distinct profiles of cyberbullying and cybervictimization were identified among left-behind adolescents. (2) Left-behind adolescents were more likely to experience cybervictimization compared to their non-left-behind peers. (3) Reactive anger, left-behind patterns, gender, and grade level significantly predicted subgroup membership. These findings underscore the importance of developing targeted interventions and considering the specific psychosocial vulnerabilities of left-behind youth. Show less

Signal-induced proliferation-associated 1 like 3 (SIPA1L3) is a member of the protein family. Very limited data are currently available regarding the role of SIPA1L3 in human carcinoma. Therefore, in this study, we investigated the expression pattern and function of SIPA1L3 in non-small cell lung cancer (NSCLC). We analyzed the distribution of SIPA1L3 in NSCLC specimens by immunohistochemistry, the relationship between SIPA1L3 expression and patient clinicopathological features, and investigated the effect of SIPA1L3 on cell growth and invasion in vivo and in vitro using small interfering RNA. Western blotting and immunoprecipitation were performed to demonstrate the interaction between SIPA1L3 and tight junction-associated angiomotin (AMOT) and Pals1-associtated tight junction protein. We found that SIPA1L3 was overexpressed in NSCLC clinical tissue samples and was associated with several clinicopathological factors. SIPA1L3 affects the proliferation and invasion of cancer cells both in vivo and in vitro. Using a SIPA1L3 mutant, we found that SIPA1L3 interacts with AMOT through its PDZ domain, which inhibits the binding of AMOT to Pals1-associtated tight junction protein and further decreases AMOT anchoring to tight junctions. Our findings suggested that SIPA1L3 promotes tumorigenesis in lung cancer cells through its PDZ domain-mediated interaction with AMOT, suggesting that SIPA1L3 is a novel candidate gene that contributes to the malignant phenotype of lung cancer.

The effects of starvation and re-feeding on Jian carp (Cyprinus carpio var. Jian) remain incompletely understood. This study investigated changes in growth performance, liver antioxidant capacity, intestinal morphology, fatty acid profile, and expression of genes related to lipid metabolism. Juvenile C. carpio var. Jian, with initial body weight of 29.50 ± 2.00 g, were reared in 15 cylindrical culture barrels (200L) at a stocking density of 10 fish per barrel. These fish were subjected to five feeding regimes: a continuous feeding group (control group, treatment A), complete fasting (treatment B), 1, 2, and 3 days starvation within one week, followed by re-feeding 6 days (treatment C), 5 days (treatment D), and 4 days (treatment E). The results indicated significantly lower growth performance in C. carpio var. Jian in treatments B and E compared to the control and treatment C (P < 0.05). Intestinal length (only 627 ± 13.14 μm in treatment B) was significantly reduced, and an increase in vacuoles was observed in C. carpio var. Jian with the prolonged starvation. Antioxidant enzyme activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were significantly (P < 0.05) improved in treatment C when compared with treatments B, D and E.. In contrast, malondialdehyde (MDA) value was lowest (12.62 ± 0.60 nmol/mL) in treatment B. Furthermore, continuous starvation significantly decreased the total lipid and fatty acids contents in the muscle (P < 0.05). Compared with the control group, the reduction of total lipid and fatty acids contents was 31.53 % and 4.57 %, respectively, particularly affecting n3PUFA and n6PUFA. However, after one-day re-feeding, these contents resumed. Lipid metabolism is closely related to fish health, while in the current study, the genes related to lipid metabolism including lipoprotein lipase (LPL), 6-phosphogluconate dehydrogenase (G6PD), and peroxisome proliferator-activated receptor alpha (PPARα) did not differ significantly in treatment C compared to the control group (P > 0.05). In contrast, expressions in treatments B, D, and E were significantly reduced (P < 0.05). Taken together, prolonged starvation (>one day per week) not only affected the growth, which may further disrupt the intestinal structure, weaken antioxidant capacity, but also attenuate lipid deposition.

Metabolic dysfunction-associated fatty liver disease (MAFLD), driven by dyslipidemia and hepatic lipid deposition, has become a major public health concern. Angiopoietin-like protein 3 (ANGPTL3), a lipoprotein lipase (LPL) activity inhibitor, can inhibit triglycerides (TGs) decomposition, and fibroblast growth factor 21 (FGF21) enhances fatty acids' β-oxidation in liver. We constructed a novel fusion protein combining the anti-ANGPTL3 nanobody FD03 and FGF21 (FD03-FGF21), which exerted appropriate binding affinities to ANGPTL3 and β-Klotho respectively. Our results showed FD03-FGF21 restored bioactivity of LPL which inhibited by ANGPTL3 and activated downstream pathway of FGF21 in iLite FGF21 assay-ready cells. Next, FD03-FGF21 showed a significant therapeutic effect in MAFLD mice, including attenuation of metabolic dyslipidemia, hepatic lipid accumulation, and impaired glucose tolerance. Compared to other treatments, FD03-FGF21 achieved the most significant therapeutic effect with a 79.78 % attenuation of low-density lipoprotein cholesterol (LDL-C) and a 95.8 % reduction of hepatic lipid accumulation. Mechanistically, transcriptomic analysis revealed that differential expression genes (DEGs) were principally clustered into lipid metabolism and oxidative stress pathways after the fusion protein treatment, especially the key lipid metabolism genes of LDLR and CD36 were significantly upregulated and downregulated respectively, as confirmed by WB. Furthermore, lipidomic and metabolomic analysis indicated the fusion protein ameliorated disorders in lipid and protein metabolism mainly through the downregulation of DG and upregulation of PC. Hepatic oxidative stress and inflammation were significantly reduced after administration of the fusion protein in MAFLD mice. Collectively, FD03-FGF21 represents an effective therapeutic strategy for MAFLD therapy through ameliorating lipid metabolism and oxidative stress. Show less

However, the underlying genetic causes in most individuals remain unclear. Here, 101 individuals with CHD and their unaffected parents were included in this study. Chromosomal microarray analysis (CMA) as a first-tier clinical diagnostic tool was applied for all affected individuals, followed by trio-based whole exome sequencing (WES) of 76 probands and proband-only WES of 3 probands. We detected aneuploidies in 2 individuals (trisomy 21 and monosomy X), 21 pathogenic and likely pathogenic copy number variants (CNVs) in 19 individuals, and pathogenic and likely pathogenic SNVs/InDels in 8 individuals. The combined genetic diagnostic yield was 28.7%, including 20.8% with chromosomal abnormalities and 7.9% with sequence-level variants. Eighteen CNVs in 17 individuals were associated with 13 recurrent chromosomal microdeletion/microduplication syndromes, the most common being 22q11.2 deletion syndrome. Pathogenic/likely pathogenic sequence-level variants were identified in 8 genes, including GATA6, FLNA, KANSL1, TRAF7, KAT6A, PKD1L1, RIT1, and SMAD6. Trio sequencing facilitated the identification of pathogenic variation (55.6% were de novo missense variants). In individuals with extracardiac features, the overall detection rate was significantly higher (61.5%) than in individuals with isolated CHD (17.3%) (P = 4.6 × 10 Show less

Axin1 plays a critical role in regulating the Wnt/β-catenin signaling pathway and cancer progression, and its polymerization is indispensable for the assembly of the β-catenin destruction complex. However, the mechanisms that control Axin1 polymerization are limited. Here, we reveal that TRIM15 interferes with the polymerization of Axin1, thereby promoting Wnt activation and colorectal cancer growth. Mechanistically, TRIM15 strongly interacts with Axin1 through its coiled-coil domain to disrupt the polymerization among Axin1 molecules. Manipulation of TRIM15 expression dramatically weakens Wnt signaling, cell proliferation, and tumor growth. Furthermore, conditional genetic ablation of Trim15 in mice inhibits tumor formation in both AOM/DSS-induced and Apc Show less

The efficacy and mechanism of Fufang Danshen dripping pills (FFDS) in the secondary prevention of stable coronary heart disease (SCHD) is currently undetermined. This study aims to investigate the efficacy and preliminary mechanism by which FFDS may impact the progression of SCHD. Based on randomization, we administered oral FFDS to 30 patients with SCHD in addition to conventional treatment for 30 days. After treatment, three-months major adverse cardiovascular events (MACE) were assessed as the primary outcome. Additionally, we evaluated the patients' Seattle Angina Questionnaire score, blood pressure, circulating levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, C-reactive protein, platelets, alanine aminotransferase, aspartate aminotransferase, serum creatinine, and fasting blood glucose as the secondary outcomes. Furthermore, we utilized mass spectrometry analysis, network pharmacology, and lipidomics to predict the potential mechanisms of FFDS in the treatment of SCHD. Following treatment, FFDS demonstrated significant improvements in serum triglyceride levels ( In individuals with SCHD, the administration of FFDS has been shown to effectively reduce circulating triglyceride levels and decrease the frequency of angina episodes. This therapeutic effect is likely due to the active components of FFDS targeting key proteins: LPL, CD36, FABPpm, L-FABP, LCAT, and CEPT. https://www.chictr.org.cn/, identifier (ChiCTR2400080149).

Previous studies have shown that astrocytes can transfer healthy mitochondria to dopaminergic (DA) neurons, which may serve as an intrinsic neuroprotective mechanism in Parkinson's disease (PD). LRRK2 G2019S is the most common pathogenic mutation associated with PD. In this study, we explored whether mitochondrial transfer is influenced by genetic and environmental factors and whether dysfunction in this process is one of the mechanisms of the pathogenic LRRK2 G2019S mutation. DA neurons and astrocytes were differentiated from induced pluripotent stem cells generated from the peripheral blood of a healthy individual and a PD patient carrying the LRRK2 G2019S mutation. A coculture system of astrocytes and DA neurons was established to explore the pathogenic mechanisms of LRRK2 G2019S. Exposure to the environmental toxin rotenone impaired mitochondrial transfer from astrocytes to DA neurons. Compared with the co-culture system from the healthy participant, the co-culture system harboring the LRRK2 G2019S mutation experienced more pronounced damage. Specifically, STX17 was colocalized with the mitochondrial outer membrane marker TOM20, and its knockdown caused damage to mitochondrial transfer. Drp1 interacted with STX17. LRRK2 G2019S-mutant astrocytes exhibited markedly increased phosphorylation of Drp1 at Ser616 upon rotenone exposure. Moreover, the degree of colocalization of STX17 with TOM20 decreased. The Drp1 phosphorylation inhibitor DUSP6 restored the colocalization of STX17 and TOM20, as well as the mitochondrial transfer efficiency and neuronal survival. The impairment of mitochondrial transfer is a potential pathogenic mechanism associated with LRRK2 G2019S mutation. The molecular mechanisms of mitochondrial transfer were observed to occur through a Drp1-STX17-dependent pathway. Notably, inhibitors for Drp1 Ser616 phosphorylation may offer neuroprotection through mitigating mitochondrial transfer impairments. This study provides novel insights into the pathogenesis of PD and the development of new therapeutic targets. Show less

Accumulation of various genetics and epigenetics alterations are accepted to result in the initiation and progression of hepatocellular carcinoma (HCC), and its high metastasis is viewed as a critical bottleneck leading to its treatment failure. Amongst them, the microRNAs arising from the lack of the antioxidant transcription factor Nrf2 lead to cancer metastasis. However, much less is known about the regulation of microRNAs by Nrf1, even though it acts as an essential determinon of cell homoeostasis by governing the transcriptional expression of those driver genes contributing to the EMT involved in its metastasis. In this study, distinct EMT phenotypes resulted from specific knockouts of Nrf1 and Nrf2 in HepG2 cells, as accompanied by their differential migratory and invasive capabilities. The Show less

The liver‒brain axis is critical in neurodegenerative diseases (NDs), with lipid metabolism influencing neuroinflammation and microglial function. A systematic investigation of the genetic relationship between lipid metabolism abnormalities and ND, namely, Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS), is lacking. To assess potential causal links between ND and six lipid parameters, two-sample Mendelian randomization (MR) was used. Large-scale European ancestry GWAS data for lipid parameters and ND (AD, ALS, PD, and MS) were used. Genetic variants demonstrating significant correlations (P < 5 × 10 MR via the inverse-variance weighted method revealed causal effects of cholesterol (CHOL, OR = 1.10, 95% CI: 1.03-1.18, P = 4.23 × 10⁻ Higher CHOL and LDLC levels were associated with increased ALS risk, suggesting a potential causal link, and supporting the liver‒brain axis hypothesis in ND. Current genetic evidence does not support a significant role for lipid metabolism in PD and MS etiology, suggesting the relationship between lipid metabolism and other NDs may be more complex and warrants further investigation.
