KRAS We studied short-term changes in signaling and mechanisms of primary resistance to AZD4625 in twelve KRAS Sustained tumor regression in four (33%) PDXs was observed while the remaining eight models were intrinsically resistant to AZD4625. Organoid responses to AZD4625 were concordant with their derived PDXs. Acute AZD4625 exposure significantly decreased gene expression of the ERK1/2 negative regulator, DUSP6, in all models while protein MAPK and AKT/mTOR signals were downregulated more frequently in the AZD4625-sensitive than AZD4625-resistant cohorts. Analyzing PDX transcriptomes and proteomes identified mTOR signaling as a putative mechanism of primary resistance to AZD4625. Our findings confirm AZD4625 as a highly active KRAS Show less

Families with children diagnosed with autism spectrum disorder (ASD) often encounter significant challenges, manifesting in elevated stress levels and compromised physical and mental well-being. This study employed Latent Profile Analysis (LPA) to comprehensively examine family resilience attributes among 328 Chinese parents of children with ASD. Drawing on Walsh's family resilience framework and the Double ABCX stress-adaptation model, the research examined how protective factors (social support, posttraumatic growth) and risk factors (family stressors) distinctively characterize resilience profiles and predict profile membership, alongside sociodemographic correlates. Through rigorous statistical analysis, the following three distinct family resilience profiles emerged: adversity (32.31%; characterized by low resilience), ordinary (46.65%; demonstrating moderate resilience) and growth (21.03%; exhibiting high resilience). Critically, the findings revealed that higher family income, perceived social support and posttraumatic growth were associated with higher family resilience, while family stressors were associated with lower family resilience. These insights underscore the importance of developing targeted, personalized intervention strategies that can effectively enhance familial coping mechanisms and psychological adaptation for families navigating the complex challenges of ASD.

Colorectal cancer (CRC) remains a major global health challenge, underscoring the need for reliable biomarkers to improve prognosis and therapeutic stratification. In this study, we comprehensively investigated the expression pattern, clinical significance, molecular functions, and immunological implications of LINGO1 in CRC. Integrative analyses of TCGA and GEO datasets, together with validation in 72 clinical CRC samples, demonstrated that LINGO1 is markedly overexpressed in tumors and strongly associated with advanced clinicopathological features and poor patient outcomes. Functional experiments revealed that both knockdown of LINGO1 in SW480 and LoVo cells and overexpression of LINGO1 in HCT116 cells significantly modulate malignant phenotypes, including proliferation, migration, invasion, and angiogenic capacity. Transcriptome-wide and pathway enrichment analyses further indicated that high LINGO1 expression is linked to epithelial-mesenchymal transition, angiogenesis, Wnt/β-catenin signaling, and other oncogenic pathways. Immunogenomic profiling, supported by multiplex immunofluorescence staining, showed that elevated LINGO1 is associated with an immunosuppressive tumor microenvironment characterized by reduced CD8⁺ T-cell infiltration and diminished GZMB expression, alongside upregulation of multiple immune checkpoint molecules. Collectively, our findings identify LINGO1 as a novel oncogenic driver and immune-modulatory biomarker in colorectal cancer, with potential value for prognosis and therapeutic targeting. Show less

ApoB (apolipoprotein B)-containing lipoproteins are causal risk factors for atherosclerotic coronary artery disease (CAD). Since human cathelicidin LL-37 binds to ApoB-100 in this pathological context, we investigated whether the circulating LL-37-ApoB-100 complex could serve as a biomarker for CAD. We performed surface plasmon resonance and protein-protein docking to demonstrate the direct LL-37-ApoB-100 interaction. We developed a specific polyclonal antibody against the complex and measured its levels in human atherosclerotic plaques and plasma, as well as in We identified that LL-37 directly interacted with multiple distinct binding sites on ApoB-100. Plasma levels of LL-37-ApoB-100 complex were significantly elevated in human patients with atherosclerosis. Consistently, levels of this complex were positively correlated with atherosclerotic plaque area in Circulating LL-37-ApoB-100 levels are strongly associated with angiographically documented CAD, highlighting LL-37-ApoB-100 as an independent predictor for CAD.

Improving Internet addiction among nursing students is of great significance to the future development of the nursing industry. Previous studies have proved that childhood trauma is closely related to Internet addiction. However, the direct relationship between alexithymia and childhood trauma and Internet addiction has not been fully explored. The aim of this study is to identify different subgroups of nursing students based on their childhood trauma and to examine the mediating role of alexithymia between childhood trauma and Internet addiction. From April to May 2025, 3,697 nursing students were recruited as samples from Shandong, Hubei, Hunan, and Henan provinces in China by convenient sampling. This survey collected social demographic data. Including The Childhood Trauma Questionnaire - Short Form (CTQ-SF), the Toronto Alexithymia Scale (TAS-26), and the Internet addiction Scale. Potential profile analysis was used to determine the potential categories of childhood trauma characteristics of nursing students, and Pearson correlation analysis, Bayesian factor robustness analysis and mediation analysis were used to determine the potential relationships among variables. LPA identified three distinct groups based on their dominant usage: low (77.4%), medium (19.5%), and high (3.1%). In the relationship between childhood trauma and Internet addiction based on potential profile analysis, alexithymia has a significant mediating effect (SE = 0.442,95%CI = 0.095, 1.824; SE = 0.219, 95%CI = 0.093, 0.962). There is heterogeneity in childhood trauma among nursing students. Alexithymia plays an important mediating role in the relationship between childhood trauma and Internet addiction. It is suggested that nursing educators pay attention to the differences in childhood trauma among nursing students, provide corresponding psychological counseling for different students, improve them, thereby alleviating Internet addiction among nursing students and promoting their mental health.

Atherosclerosis (AS) is a chronic disease characterized by lipid deposition in the vascular intima. As the pathological basis of cardiovascular diseases, AS represents a major contributor to global morbidity and mortality. While Gualou Huoxue Jiedu Decoction (GHJD) has been widely used in clinical practice for the treatment of AS, the molecular mechanisms remain unclear. To investigate the anti-atherosclerotic effects and underlying mechanisms of GHJD. Apoe GHJD alleviated plaque formation, improved lipid metabolism, and suppressed inflammation in vivo. Multi-omics analysis revealed that DNA methylation of Mfap4 could be a pivotal target of GHJD efficacy. In vitro assays confirmed that GHJD suppressed Mfap4 transcription and translation, leading to downregulation of integrin receptor family expression and inhibition of VSMC phenotypic switching. GHJD exerts anti-atherosclerotic effects through epigenetic modulation of Mfap4 and downstream integrin/FAK signaling pathway, thereby inhibiting VSMC phenotypic switching. These findings provide pharmacological evidence supporting GHJD as a potential therapy for AS and, for the first time, validate MFAP4 as a pharmacological target, offering new insights into AS prevention and treatment.

This first-in-human Phase I study evaluated the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of KN069, a novel dual Glucagon-like peptide-1 receptor agonist (GLP-1RA)/Glucose-dependent insulinotropic polypeptide receptor (GIPR) antagonist in Chinese men with overweight/obesity. This randomised, double-blind trial included a single ascending dose (SAD; 12-120 mg, N = 36, 3:1 active-to-placebo) and a multiple ascending dose (MAD; N = 12, dose escalation 15-60 mg) phase. Safety was assessed via adverse events (AEs) and compliance. PK was analysed using a sandwich enzyme-linked immunosorbent assay (ELISA) for Intact and Total KN069. PD included measurements of body weight, waist circumference, body mass index (BMI) and metabolic parameters. Immunogenicity was assessed by detecting anti-drug antibodies (ADA). KN069 was well tolerated, with predominantly mild-to-moderate gastrointestinal adverse events. PK showed dose-proportional exposure (12-90 mg) with a long half-life for Total KN069 (899.74-1099.01 h). In the SAD part, preliminary dose-dependent weight reductions were observed, with maximum early changes at Day 7 (90 mg: -4.71% vs. placebo: -0.41%) and sustained for up to 133 days. In the MAD part, Group B (60 mg) achieved a -2.57% mean weight reduction from baseline at Day 25, alongside a significant decrease in waist circumference (p = 0.0446). Metabolic improvements included lower fasting glucose, triglycerides, uric acid and elevated insulin/C-peptide. KN069 exhibits favourable safety, long-acting PK and preliminary dose-dependent weight reduction alongside expected pharmacologic metabolic effects, supporting further clinical development. gov Identifier: NCT06547775.

Dibutyl phthalate (DBP) is a widely distributed endocrine-disrupting chemical with potential carcinogenic properties, yet its role in head and neck squamous cell carcinoma (HNSC) remains unclear. Here, we applied an integrative framework combining network toxicology, Mendelian randomization (MR), multi-omics analyses, molecular docking, molecular dynamics simulations, and in vitro experiments to elucidate the mechanisms underlying DBP-associated HNSC. Lipoprotein lipase (LPL) was identified as the sole overlapping gene between DBP-related targets and HNSC-associated genes. MR analysis supported a potential causal relationship between LPL and HNSC susceptibility. Expression profiling demonstrated tissue- and cell type-specific patterns of LPL and its dysregulation in HNSC, with associations to tumor stage and prognosis. Genomic analyses revealed that LPL alterations were infrequent and mainly driven by copy number loss. LPL expression positively correlated with immune and stromal infiltration. Enrichment analyses implicated immune regulation and PI3K-AKT signaling. Molecular simulations showed stable DBP-LPL binding. Functionally, DBP promoted SCC9 proliferation and reduced LPL expression, and was associated with transcriptional changes in PI3K-AKT-mTOR-related genes, whereas LPL restoration mitigated these effects. These findings reveal a novel DBP-LPL axis in HNSC. Show less

Protocatechuic acid (PCA), a natural compound found in a variety of Chinese herbal medicines and plant foods, has been documented to inhibit atherosclerosis partially by reducing inflammation burden in arterial endothelial cells. Interestingly, in vitro studies showed that PCA at physiologically reachable concentrations does not affect inflammation burden in TNF-α-stimulated aortic endothelial cells, whereas it increases the content of exosomal miR-10b secreted by macrophages that have engulfed apoptotic cells (efferocytic macrophages). This study was aimed at investigating whether the in vivo anti-inflammatory effect of PCA in arterial endothelial cells was due to the uptake of efferocytic macrophage exosomal miR-10b. A transwell co-culture system of aortic endothelial cells with efferocytic macrophages was used to evaluate the effect of PCA on NF-κB-mediated inflammation in aortic endothelial cells. An inhibitor of exosome secretion, GW4869, was applied to confirm the role of exosomes played in the anti-inflammatory effect of PCA. The aortic endothelial cells were administrated with exosomes isolated from PCA-treated efferocytic macrophages or miR-10b mimic or antagomir to ascertain the role of miR-10b in downregulating inflammation effect of PCA. Bioinformatics analyses, loss-of- and gain-of-function assays and luciferase reporter gene assays were performed to identify targeting relationship between miR-10b and mitogen-activated protein kinase kinase kinase 7 (MAP3K7)/β-transducin repeat-containing protein (β-TrCP). Besides, Apoe PCA at physiologically reachable concentrations inhibited NF-κB-mediated inflammation in TNF-α-stimulated aortic endothelial cells co-cultured with efferocytic macrophages, in which treatment of GW4869 reversed this effect. Exosomes isolated from PCA-treated efferocytic macrophages inhibited inflammation and increased miR-10b levels in aortic endothelial cells. Mechanistically, exosomal miR-10b post-transcriptionally repressed MAP3K7 and β-TrCP, both of which promote NF-κB activation. Knockdown of Map3k7 and Btrc with siRNA in aortic endothelial cells abolished the inhibitory effects of exosomes isolated from PCA-treated efferocytic macrophages on NF-κB-mediated inflammation. Consistently, oral administration of PCA increased miR-10b level and inhibited Map3k7 and Btrc mRNA expression as well as inflammation in aortic endothelial cells in Apoe Our current findings suggest that PCA could transfer exosomal miR-10b from efferocytic macrophages to endothelial cells and thus inhibit NF-κB-mediated inflammation in arterial endothelial cells through repressing MAP3K7 and β-TrCP, two new targets of miR-10b.

Lipoprotein(a) [Lp(a)] is a genetically determined independent risk factor for atherosclerotic cardiovascular disease (ASCVD) that drives a significant residual risk through proatherogenic, proinflammatory, and prothrombotic pathways. However, current mainstay lipid-lowering therapies such as statins have limited efficacy in reducing Lp(a) levels, highlighting a critical therapeutic gap. This review aims to synthesize evidence on the role of Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) inhibitors in targeting Lp(a). We systematically searched PubMed and Embase for clinical trials and mechanistic studies (2010-2025), using the PRISMA and AMSTAR-2 frameworks to ensure methodological rigor and demonstrated that PCSK9 inhibitors (eg, alirocumab, evolocumab, and tafolecimab) not only reduced low-density lipoprotein (LDL-C) by 55%-60% but also lowered Lp(a) by 20%-30%. The efficacy of these agents varies ethnically, with tafolecimab showing superior performance in East Asian populations, which is partly attributable to the higher prevalence of the PCSK9 R46L loss-of-function allele. Mechanistically, PCSK9 inhibitors lowered Lp(a) levels through 2 pathways: suppression of hepatic synthesis and enhanced plasma clearance. This evidence supports the 2023 ESC guidelines, which issued a Class IIa recommendation for PCSK9 inhibitor use in patients with ASCVD and elevated Lp(a) levels. Given the evolving landscape, further research is warranted to confirm the role of these therapies in precision medicine paradigms for managing Lp(a)-associated risks. Show less

The abuse of methamphetamine (METH) is associated with an increased risk of Parkinson's disease (PD), whereas microglial polarization and glucose metabolism disorders are closely related to the progression of PD. This study aimed to investigate the specific molecular mechanism underlying the promotion of PD progression by METH through the regulation of microglial polarization and glycolysis. METH-induced C57BL/6 mice and BV2 cells were used to construct PD-like neurotoxicity animal and cell models for experimental investigation. Behavioral tests, immunohistochemistry and Nissl staining were used to assess the behavioral ability and neuronal damage of the animals. The levels of related proteins, inflammatory cytokines and glycolysis were detected using immunofluorescence, ELISA, Western blotting, and CCK-8 assays. METH treatment significantly promoted behavioral disorders in PD mice, reduced the number of TH-positive neurons, and aggravated neuronal damage in the substantia nigra (SN). In addition, METH decreased the M2 marker proteins Arg-1 and CD206 and increased the M1 marker proteins iNOS and CD86; the proinflammatory cytokines TNF-α, IL-β, and IL-6; and glucose uptake, glucose consumption and lactic acid production, thus promoting M1 polarization and glycolytic activity in BV2 cells. In terms of the underlying molecular mechanism, METH treatment significantly increased the level of LPA. METH promotes LPA expression via upregulation of LIPH expression, and activates the PI3K/AKT pathway. Knockdown of LIPH or treatment with BrP-LPA reduces the ability of METH to promote M1 microglial polarization and glycolytic activity. Furthermore, the addition of the PI3K/AKT signaling pathway activator 740 YP weakened the inhibitory effect of BrP-LPA on the above process. METH may promote M1 polarization and glycolytic activity in microglia by activating LIPH/LPA/PI3K/AKT signaling, thus promoting the progression of PD. Show less

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive dysfunction that is closely associated with cholinergic system damage. Estrogen deficiency is a well-established risk factor for AD in women. Osthole (OST), a phytoestrogen with mild, bidirectional regulatory properties, has been proposed as a potential estrogen replacement. This study aimed to investigate the mechanisms by which OST ameliorates cognitive impairment. Cognitive deficits were induced in female Sprague-Dawley rats by bilateral ovariectomy (OVX), and OST was subsequently administered by oral gavage. Behavioral tests revealed that OST significantly improved learning and memory and reduced anxiety-like and depression-like behaviors in OVX rats. H&E staining and Nissl staining demonstrated that OST reversed neuronal damage in the hippocampus and cortex. Western blotting, ELISA, and immunofluorescence staining indicated that OST treatment restored the estrogen-cholinergic-NGF axis: E Show less

Hypertrophic scar (HS) is a fibroproliferative disorder characterized by fibroblast hyperactivation and aberrant extracellular matrix deposition. This study identifies macrophage-derived lactate as a key mediator of fibroblast phenotypic remodeling via monocarboxylate transporter 1 (MCT1)-mediated histone H3 lysine 23 lactylation (H3K23la) in HS. Elevated lactate levels and MCT1 expression were observed in HS tissues, with macrophages in stiff mechanical microenvironments identified as the primary lactate source. Lactate influx through MCT1 upregulated H3K23la, thereby promoting transcriptional activation of profibrotic genes HEY2 and COL11A1. Mechanistically, HEY2 activated YAP1/SMAD2 signaling, while COL11A1 stabilized MCT1 to enhance lactate transport, forming a positive loop that amplified fibrosis. Fibroblast-specific Mct1 deletion or pharmacological inhibition of Mct1 in male mice reduced collagen deposition, accelerated wound healing, and attenuated scar formation. Our findings redefine the macrophage-fibroblast crosstalk in HS and establish the MCT1-H3K23la-HEY2/COL11A1 axis, particularly its self-reinforcing loop, as a novel therapeutic target. Show less

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

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

High-density lipoprotein(a) (Lp(a)) is a well-established independent risk factor for atherosclerotic cardiovascular diseases (ASCVD). However, the interaction between Lp(a), low-density lipoprotein cholesterol (LDL-C), and polygenic risk score (PRS) in cardiovascular diseases has been the subject of relatively limited research. The present study included a total of 346,751 participants from the UK Biobank. According to the guideline of Lp(a), the study subjects were divided into 3 groups: the first group was <75 mmol/L (n = 272,643), the second group was 75 to 125 mmol/L (n = 35,792), and the third group was >125 mmol/L (n = 38,316). Elevated Lp(a) levels were associated with a progressively increased risk of overall cardiovascular events (CVEs), including ischemic stroke (IS), coronary heart disease (CHD), angina pectoris, and myocardial infarction (MI). In contrast, the risks of atrial fibrillation (AF) and heart failure (HF) decreased with higher Lp(a) levels. Additive interaction analyses revealed significant synergistic effects between Lp(a) and LDL-C for CHD (relative excess risk interaction [RERI] = 0.081, attributable proportion of interaction [AP] = 0.046, synergy index [SI] = 1.117), angina pectoris (RERI = 0.112, AP = 0.055, SI = 1.121), and MI (RERI = 0.183, AP = 0.079, SI = 1.161), with MI showing the strongest synergy. Incorporating PRS further amplified these effects, and the RERI (CHD: RERI = 0.721; angina pectoris: RERI = 0.781; MI: RERI = 1.318) and SI (CHD: SI = 2.218; angina pectoris: SI = 1.97; MI: SI = 2.326) were significantly higher than those of the interaction model containing only Lp(a) and LDL-C. In conclusion, Lp(a) and LDL-C show a significant synergistic effect in ASCVD, and this effect is more prominent in individuals with a higher PRS, suggesting that dual lipid management should be strengthened for such populations. While AF and HF may require alternative risk factor management. Show less

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

This study aims to demonstrate the effect of toadflax (bufalin) on erlotinib resistance in nonsmall cell lung cancer (NSCLC) by inhibiting the fibroblast growth factor receptor (FGFR). The microfluidic mobility transferase and caliper mobility-shift assays were employed to detect the FGFR inhibition by bufalin and the binding reversibility. Further, the inhibitory effects of bufalin were determined in HCC827 and HCC827/ER cells in vitro , investigating relative FGFR overexpression by quantitative reverse transcriptase-PCR (RT-qPCR) and FGFR downstream proteins, that is, FGFR substrate 2 (FRS2), extracellular signal-regulated kinase (ERK), and S6 by western blot analysis. Finally, HCC827/ER-inoculated xenograft tumors were constructed to observe the effects of bufalin and bufalin + erlotinib intervention on tumor growth. Bufalin inhibited FGFR by reversibly binding to FGFR1. In addition, the western blot analysis indicated a significant reduction in the expression levels of FGFR, FRS2, ERK, and S6 proteins in HCC827 and HCC827/ER cells, increasing the expression levels of apoptotic caspase-3 and poly-(ADP-ribose) polymerase proteins. Bufalin + erlotinib combination significantly inhibited the apoptosis of HCC827/ER cells and subsequent tumor growth in vivo . In addition, FGFR overexpression significantly reversed the sensitivity of bufalin to HCC827/ER cells, promoting the value-addition of HCC827/ER cells. Further, bufalin + erlotinib significantly reduced the growth of erlotinib-resistant HCC827/ER tumors, induced apoptosis, and inhibited the expression of FGFR and p-ERK proteins. These findings indicated that bufalin could reverse the erlotinib resistance in NSCLC by inhibiting the FGFR expression. Show less

This study established a hyperlipidemia model by feeding Sprague-Dawley rats a high-fat diet for 8 weeks. The rats were randomly assigned to the following groups: model group, atorvastatin calcium group(4.8 mg·kg~(-1)), low-, medium-, and high-dose Tanyu Tongzhi Optimization Decoction(TYTZD) groups(3.6, 7.2, and 14.4 g·kg~(-1)), and a normal diet control group. After 4 weeks of continuous administration, hematoxylin-eosin(HE) and oil red O staining were used to observe liver pathological changes and lipid infiltration. Automatic biochemical analyzer were performed to assess blood lipid profiles, coagulation function, and liver function. Transcriptomic and proteomic analyses were employed to identify differentially expressed genes(DEGs) and proteins(DEPs), followed by enrichment analysis. The MCODE algorithm was applied to classify DEGs and DEPs into modules, and network separation index(S₍AB)) was calculated to assess module separation, enabling construction of a gene-protein co-expression network for core target screening. The diagnostic accuracy of core targets was evaluated by area under the receiver operating characteristic(ROC) curve(AUC), and ELISA was used to measure core target expression. Western blot detected the expression of core pathway-related proteins in liver tissue. RESULTS:: demonstrated that TYTZD significantly improved dyslipidemia, coagulation dysfunction, liver injury, hepatic pathology, and lipid infiltration in hyperlipidemic rats. Transcriptomic analysis identified 571 DEGs significantly reversed by TYTZD, mainly enriched in inflammatory signaling pathways such as Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB). Proteomic analysis identified 102 reversed DEPs, mainly involved in cholesterol metabolism pathways. Integrated analysis identified core targets including TLR4, tumor necrosis factor-α(TNF-α), integrin subunit alpha M(ITGAM), Toll-like receptor 2(TLR2), matrix metalloproteinase 9(MMP9), interleukin-1β(IL-1β), apolipoprotein E(APOE), and apolipoprotein C2(APOC2), all with AUC values greater than 0.70. ELISA showed that TYTZD intervention significantly downregulated MMP9, TNF-α, IL-1β, TLR2, ITGAM, and TLR4, and upregulated APOC2 and APOE. Western blot indicated that TYTZD reduced TLR4, p-NF-κB, and IL-1β protein expression in liver tissue. In conclusion, TYTZD may exert anti-hyperlipidemic effects through regulation of core targets such as ITGAM, TLR4, and APOC2, and by modulating the TLR4/NF-κB signaling pathway to intervene in inflammatory responses and cholesterol metabolism, thereby achieving multi-target, multi-pathway therapeutic effects against hyperlipidemia.

Autophagy supports clear cell renal cell carcinoma (ccRCC) progression, yet its upstream regulatory mechanisms remain to be fully defined. Integrating bulk, single-cell, and spatial transcriptomics, we identify a regulatory axis wherein the transcription factor ZBED6 activates the expression of the autophagy-initiating kinase PIK3C3 via the repression of IGF2, thereby driving pro-tumorigenic autophagy. Spatial analysis confirms the co-localization of ZBED6 and PIK3C3 in tumor tissues. Using genes associated with this axis, we develop a six-gene prognostic signature that stratifies patients with distinct survival outcomes and differential responses to immunotherapy and targeted therapy. Functional assays show that ZBED6 promotes ccRCC cell proliferation, migration, and invasion. This work elucidates a pathway governing autophagy in ccRCC and provides a framework for prognostic assessment and precision therapy. Show less

Keratoconus (KC) is a progressive disorder of corneal thinning characterized by responses in the extracellular matrix and cellular interactions. This study used bioinformatics methods to identify key genes involved in KC development and in anoikis and endoplasmic reticulum (ER) stress. KC and control datasets from the GEO database were analyzed to identify differentially expressed genes (DEGs). These were cross-referenced with anoikis and ER stress-related genes from Genecards. Functional enrichment, immune infiltration analysis, and machine learning techniques (LASSO, Random Forest) were used to identify candidate molecular signatures, which were then validated in an animal model. We identified 46 DEGs associated with anoikis and 41 DEGs related to ER stress. Functional analysis linked them to apoptosis and IL-17 signaling. Five key molecular signatures were identified: CDKN1A, MCL1, PTGS2, PTHLH, and ANGPTL4. The expression of ANGPTL4, CDKN1A, and MCL1 was consistent in the animal model. These genes are associated with inflammatory and oxidative stress responses. Twelve potential therapeutic drugs were predicted. This study identifies five candidate molecular signatures for KC related to anoikis and ER stress, offering insights into KC pathogenesis and potential targeted therapies. Show less

To determine the prevalence of CHD7, FGFR1 and ANOS1 variants and the impacts of their splicing variants on mis-splicing in patients with congenital hypogonadotropic hypogonadism (CHH). Based on the whole-exome sequencing data from 280 CHH probands, we identified 15 potential splice-site variants in CHD7, ANOS1 and FGFR1 by using in silico software. The functional consequences of these variants were analyzed by the minigene assay or RT-PCR analyses of RNA taken from the peripheral lymphocytes. Detailed phenotyping was performed in the CHH patients harboring deleterious variants and their available family members. 11 out of 15 potential splice-site variants were demonstrated to cause mis-splicing, resulting in loss of function through deletion, insertion or frameshift of amino acids in the proteins. Most patients with deleterious splice-site variants in CHD7, ANOS1, FGFR1 presented with gene-specific non-reproductive phenotypes, confirming the pathogenic contribution of these variants to CHH. Our study indicated that splice-site variants in CHD7, ANOS1, FGFR1 underlie the genetic basis of ~3.9% of CHH patients, warranting the inclusion of potential splice-site variants for genetic diagnosis and counseling of CHH.

Dual GIP/GLP-1 receptor agonists have gained significant attention in clinical applications because of their remarkable efficacy in reducing obesity and type 2 diabetes. However, the mechanisms by which these dual agonists affect systemic metabolism remain elusive. To investigate the effects of a novel dual-receptor agonist, THDBH120, on systemic metabolism in obese individuals and the specific roles of GIPR and GLP-1R in modulating systemic and adipose tissue metabolism. To evaluate the intrinsic properties of THDBH120, we conducted a potency assay by using HEK293 cell lines overexpressing either human GIPR or GLP-1R and measured the accumulation of cAMP as a downstream second messenger following receptor activation. To evaluate the efficacy of THDBH120 on systemic metabolism, we used obese rodents and nonhuman primate species that received various doses and frequencies of THDBH120. To determine the metabolic roles of GLP-1R and GIPR in mediating the beneficial effects of THDBH120, we used GLP-1R- and GIPR-knockout mouse models treated with THDBH120, the GLP-1R agonist semaglutide, or the GIPR agonist LAGIPRA and performed transcriptomic sequencing analyses of adipose tissues. THDBH120 is a novel long-acting dual GIPR/GLP-1R agonist that has superior weight loss and metabolic improvement effects in rodents and mammals. The activation of GLP-1R by semaglutide or THDBH120 improved lipid metabolism, whereas the activation of GIPR by LAGIPRA or THDBH120 alleviated inflammation. THDBH120 improved lipid metabolism via GLP-1R-mediated pathways and mitigated inflammation by activating GIPR-associated pathways in the adipose tissues of obese mice. Both GLP-1R and GIPR are important in mediating the beneficial effects of dual receptors on systemic metabolism. THDBH120 is a novel long-acting dual GIPR/GLP-1R agonist that has potential clinical applications. Show less

The present study aimed to investigate the combined impact of lipoprotein (a) [Lp(a)] and low-density lipoprotein (LDL) subfractions on cardiovascular outcomes in patients with acute coronary syndrome (ACS). The study enrolled 2061 ACS patients from Tianjin Chest Hospital. Participants were categorized into 4 groups based on their Lp(a) and the concentration of the sixth component particles of LDL(LDL-P6). The primary endpoint was the occurrence of major adverse cardiovascular events (MACE). The relationship between LDL-P6, Lp(a), and MACE was evaluated. Over a mean follow-up period of 5.4 years, 456 (22.1%) patients experienced MACE. Multivariate analysis identified both LDL-P6 and Lp(a) as significant independent predictors of MACE in ACS patients. Those in the highest-risk group had a substantially higher incidence of MACE compared with the lowest-risk group (HR 5.718; 95% CI 3.703-8.829; Show less
