Hyperlipidemia and its associated hepatic steatosis pose significant global health burdens, necessitating novel therapeutic strategies. High-fat diet (HFD)-fed C57BL/6 mice received TAC (2.5, 5.0, 10.0 g/L) or simvastatin for 2 weeks. Metabolic parameters, serum lipid profiles, hepatic function markers, and histopathology were systematically analyzed. Molecular pathways were interrogated through qPCR, Western blot, and pharmacological inhibition of AMPK (Compound C) and PPARα (GW6471). TAC treatment demonstrated significant dose-dependent improvements across multiple parameters. Compared to HFD controls, TAC reduced body weight by 21.3% and liver index by 18.7%, while lowering fasting blood glucose levels by 32.4%. Serum analyses showed substantial reductions in total cholesterol (46.2%), triglycerides (38.5%), and LDL-cholesterol (52.1%), accompanied by a 29.8% increase in HDL-cholesterol. Hepatic function improved markedly, with ALT and AST levels decreasing by 57.3% and 49.6% respectively. Histopathological examination revealed a 68.4% reduction in hepatic lipid accumulation. At the molecular level, TAC treatment resulted in a 2.7-fold increase in AMPK phosphorylation while significantly reducing HMGCR expression by 63.1% and nuclear SREBP-1c levels by 71.5%. Concurrently, TAC upregulated PPARα and LXRα expression by 3.1-fold and 2.4-fold respectively, leading to enhanced expression of lipolytic enzymes LPL and HL by 2.8-fold and 2.1-fold. These beneficial effects were completely abolished by co-treatment with pathway-specific inhibitors. TAC ameliorates hyperlipidemia and hepatic steatosis through dual modulation of AMPK/SREBP-1c-mediated lipid synthesis and PPARα/LXRα-driven lipolysis, presenting a multifaceted therapeutic approach for metabolic disorders.

Observational studies have reported an association between visceral obesity and asthma. However, the causal direction of this relationship remains uncertain due to potential confounding and reverse causality. Furthermore, the underlying mediating factors and potential therapeutic targets underlying this association are poorly understood. This study aimed to investigate the causal effect of visceral adipose tissue (VAT) on asthma risk, identify potential mediators, and quantify their effects using a Mendelian randomization (MR) framework. In this study, we employed MR approach to elucidate the impact of VAT on asthma and to assess the potential mediators. Subsequently, the association between seven lipid-lowering medication targets and asthma risk was investigated using the drug target MR method. Lastly, we conducted an observational study involving 12,120 participants to evaluate the relationship between visceral adiposity index (VAI) and asthma. The univariable MR analysis demonstrated that each standard deviation increase in genetically predicted VAT was associated with a 46 % higher risk of asthma (IVW: OR = 1.460, 95 % CI: 1.351-1.578, p = 1.471E-21). This association remained significant after adjusting for BMI in multivariable MR (OR = 1.137, 95 % CI: 1.023-1.262, p = 0.017). Mediation analysis revealed that HDL-C accounted for 4.3 % of this effect (OR = 1.016, 95 % CI: 1.001-1.033, p = 0.038). Drug-target MR indicated that activation of HMGCR and LDLR reduced asthma risk (OR = 0.846 and 0.866, respectively; both p < 0.01), whereas LPL activation increased risk (OR = 1.080, p = 0.015). Observational analysis of NHANES data (n = 12,120) confirmed that higher VAI was associated with increased asthma prevalence (OR = 1.290, 95 % CI: 1.101-1.479, p = 0.010). Our results reveal a significant association between increased visceral adipose tissue and elevated risk of asthma, which is partially mediated by high-density lipoprotein cholesterol. 3-hydroxy-3-methylglutaryl coenzyme A reductase, low-density lipoprotein receptor, and lipoprotein lipase exhibit potential as therapeutic targets for asthma.

The balance between adipogenic and osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) is essential for maintaining bone homeostasis. This study aimed to investigate the role of retinoid-related orphan receptor α (RORα) in the adipogenic differentiation of BMSCs. Stable BMSC lines with RORα overexpression or knockdown were established. Adipogenic differentiation was evaluated using Oil Red O staining and by measuring the expression of adipogenic markers, including PPARγ2, LPL, LEP, FABP4, and ADIPOQ. Treatment with the RORα inhibitor SR3335 significantly promoted adipogenic differentiation, whereas the RORα agonist SR1078 exerted the opposite effect. Similarly, RORα-overexpressing (OE-RORα) BMSCs showed reduced adipogenic differentiation, while RORα knockdown BMSCs exhibited enhanced differentiation at 14 days after induction. During adipogenesis, PPARγ2 expression increased significantly, peaking at day 6 before gradually declining. Overexpression and knockdown of RORα accentuated this downregulation and upregulation, respectively, at days 6 and 12. The adipogenic marker genes lipoprotein lipase (LPL), leptin (LEP), fatty acid binding protein 4 (FABP4), and adiponectin C1Q and collagen domain containing (ADIPOQ) were markedly downregulated in RORα-overexpressing BMSCs at day 12. Moreover, RORα overexpression enhanced β-catenin nuclear translocation at day 1 post-induction and upregulated downstream WNT/β-catenin signaling molecules (Axin2, c-Myc, CD44) at day 6. Inhibition of WNT/β-catenin signaling with XAV-939 effectively reversed the suppressive effect of RORα overexpression on adipogenic differentiation and restored the expression of adipogenesis-related genes. RORα suppresses adipogenic differentiation of BMSCs, at least in part, by activating WNT/β-catenin signaling. Show less

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

BackgroundSchatzker IV-C tibial plateau fractures pose a significant challenge for adequate visualization and reduction of the lateral articular surface through a solitary posteromedial (PM) approach. This study aimed to evaluate the effectiveness of an adjunctive lateral patellar ligament (LPL) approach in enhancing articular exposure, assessed through cadaveric modeling and a clinical case series.MethodsIn a cadaveric study, eight preserved knee specimens were dissected using a combined PM and LPL approach. The exposed articular area was quantitatively measured using calibrated digital imaging and ImageJ software before and after the LPL approach was established. Clinically, a case series of 10 patients with Schatzker IV-C fractures underwent open reduction and internal fixation via the combined approach between October 2021 and December 2023. Outcome measures included intraoperative exposure, 12-month postoperative Knee Society Score (KSS), and complications.ResultsThe addition of the LPL approach resulted in a 96% increase in the mean exposed articular area (from 8.4 cm² to 16.5 cm²; Show less

Oxidative deterioration of fish oil in aquafeeds poses a significant challenge to fish health and aquaculture sustainability, making it crucial to mitigate this issue through healthy and green nutritional strategies. This study examined the potential of stevia chlorogenic acid (SCGA), a bioactive byproduct of stevia processing, to alleviate intestinal injury, gut microbiota dysbiosis, and lipid metabolism disorders induced by oxidized fish oil in turbot. Four diets with equal nitrogen and lipid contents were formulated: a control diet (PC) containing 5 % fresh fish oil, an oxidized fish oil diet (OFO) comprising 5 % oxidized fish oil, and two additional OFO diets supplemented with 200 mg/kg (OFO200) or 400 mg/kg (OFO400) of SCGA. Each dietary treatment was randomly assigned to three replicates, each containing 40 fish weighing approximately 16.99 ± 0.01 g, and administered over a 10-week period. Fish fed the OFO diet exhibited significantly compromised growth performance, as indicated by decreased WGR and SGR, along with reduced serum immune indices (IgM, C3, and C4) and lipid parameters (TC, HDL, LDL), and elevated serum D-LA levels (P < 0.05). Moreover, dietary OFO markedly suppressed antioxidant enzyme activities (serum SOD; intestinal SOD, GSH-Px, and CAT) and elevated MDA concentrations (P < 0.05). Additionally, OFO reduced intestinal expression of tight junction-associated genes (Claudin-4, Claudin-7, Occludin) while increasing expression levels of MLCK, Keap1, inflammatory mediators (IL-6, IL-1β, TNF-α2, NF-κB, IFN-γ), and Caspase7 (P < 0.05). Notably, the TLR signaling pathway-related genes were upregulated, accompanied by pronounced shifts in gut microbiota composition (P < 0.05). In hepatic tissue, lipogenesis-associated genes (FAS, ACC) were significantly increased, while key genes involved in lipid transport and β-oxidation (CD36, LPL, ACOX1, PPARγ) exhibited reduced expression (P < 0.05). Dietary supplementation with 200 and 400 mg/kg SCGA effectively mitigated these detrimental impacts. SCGA restored growth performance, serum immune parameters, and antioxidant enzyme activities to levels comparable to the PC group. It also normalized gene expression related to intestinal barrier function, inflammation, apoptosis, and hepatic lipid metabolism. Furthermore, SCGA supplementation modulated gut microbiota structure by increasing beneficial genera and decreasing potential pathogens. In conclusion, SCGA effectively improves growth performance, alleviates OFO-induced intestinal injury and microbial dysbiosis, and regulates lipid metabolism in turbot. These findings provide theoretical insights and technical support for the application of SCGA in aquaculture. Show less

Phenotypic transformation of Schwann cells (SCs) plays a crucial role in nerve regeneration. Previous studies have demonstrated that Runx2 significantly influences the biological behavior of SCs. Nonetheless, the regulatory mechanisms that govern its epigenetic regulation are not yet fully elucidated. To facilitate this investigation, an adenovirus for the overexpression of Runx2 was constructed. Healthy adult Sprague-Dawley rats, weighing between 100 and 150 g and irrespective of sex, were randomly selected for the study. After establishing a model of sciatic nerve crush injury, tissue samples were harvested for histological analysis at both 4 and 7 days post-injury. In vitro, an Runx2-overexpressing SC line was established. Thorough analysis of transcriptome data, coupled with CUT&Tag sequencing of histones and transcription factors in SCs following Runx2 overexpression, was conducted. Additionally, single-cell RNA sequencing data from GSE216665 were incorporated to elucidate the mechanistic role of Runx2. The findings were subsequently validated through dual-luciferase assays. Following nerve crush injury, Runx2-positive SCs were identified at the injury site. Through comprehensive multiomics analysis, we discovered that lipid metabolism was disrupted in Runx2-overexpressing SCs. Further investigation established a detailed super-silencer landscape in these cells, revealing that elevated Runx2 levels form a super-silencer within the transcriptional regulatory region of the Lpl gene, thereby downregulating Lpl expression. Runx2 can modulate the biological behavior of SCs by forming super-silencers that interfere with the expression of lipid metabolism genes, such as Lpl, thereby altering the metabolic capacity of SCs.

Precise differential diagnosis between lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (LPL/WM) and marginal zone lymphoma (MZL) remains a challenging issue because of overlapping clinicopathological and immunophenotypic features. In the present study, the differential diagnostic potential of CD180 was assessed by determining its expression patterns in patients with MZL and LPL/WM through flow cytometry. The results indicated that LPL/WM cases exhibited a complete absence of CD180 expression on malignant B cells, whereas MZL cases showed robust CD180 expression (P < .001). Receiver operating characteristic analysis demonstrated that CD180 expression percentage showed optimal diagnostic accuracy in LPL/WM and MZL cases (area under the curve = 0.998, sensitivity = 100%, and specificity = 98.0%), with a further improvement in differentiation potential by the CD180 mean fluorescence intensity ratio (lymphocytes/monocytes) of ≤ 0.47 (area under the curve = 0.937).

Conjugated linoleic acid (CLA) isomers have been reported to reduce body weight and promote glycolipid metabolism in animals. In a preliminary study, we revealed that trans-10, cis-12-CLA (10,12-CLA) plays an important role in modulating lipid metabolism in chickens. However, the underlying mechanism remains unclear. In this study, we constructed an isolated in vitro model with primary chicken hepatocytes to investigate the effect of 10,12-CLA on lipid metabolism. 10,12-CLA inhibited lipid accumulation by decreasing the mRNA expression of sterol regulatory element-binding protein-1c (SREBP-1c), SREBP2, 3‑hydroxy-3-methylglutaryl-CoA reductase (HMGCR), fatty acid synthase (FAS), adipose triacylglyceride lipase (ACC), and lipoprotein lipase (LPL) and increasing the mRNA expression of peroxisome proliferator-activated receptor α (PPARα), carnitine palmitoyltransferase 1 (CPT1) and adipose triacylglyceride lipase (ATGL). Furthermore, 10,12-CLA treatment activated the protein expression of extracellular signal-regulated kinase 1/2 (ERK1/2) and AMP-activated protein kinase (AMPK), whereas treatment with the ERK1/2 inhibitor U0126 reversed the inhibitory effects of 10,12-CLA on lipid accumulation by blocking the ERK1/2-AMPK pathway, leading to increased lipid accumulation and triglyceride content in primary chicken hepatocytes. These findings suggest that in chicken hepatocytes, 10,12-CLA alleviates hepatocyte lipid deposition by activating the ERK1/2-AMPK pathway, promoting fatty acid oxidation and reducing lipid synthesis, revealing the potential mechanism through which 10,12-CLA regulates hepatic lipid metabolism in chickens.

Rheumatic heart valve disease (RHD) is a chronic immune valvular heart disease caused by rheumatic fever, primarily affecting the mitral and aortic valves. It often leads to atrial fibrillation, heart failure, and even premature death. Currently, there are no effective therapeutic drugs available, partially due to the lack of appropriate therapeutic targets. To identify therapeutic targets for RHD, we employed a 2-sample Mendelian randomization approach integrating identified druggable genomics to assess the causal effect of expression quantitative trait loci of druggable genes in the blood on RHD. Subsequently, we performed Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses on the druggable genes. We used colocalization analysis to test whether the risk of RHD and gene expression are driven by common single nucleotide polymorphisms. Additionally, the Comparative Toxicogenomics Database was utilized to evaluate the impact of environmental exposures on druggable genes, and molecular docking was conducted to identify potential small molecule interactions. A total of 6888 druggable genes were collected. After conducting various Mendelian randomization analyses and applying false discovery rate correction, we identified 13 drug targets for RHD: TFRC, FMO4, CA2, HLA-DPB2, OXTR, GRAMD1B, PNP, HLA-DPB1, leukocyte immunoglobulin-like receptor B1 (LILRB1), TUBB, LGR6, F13A1, and LPL. These targets were found to be closely related to immune regulation and inflammatory response in Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. Bayesian colocalization analysis established an interaction between LILRB1 and RHD, with a PP.H4 >0.5, LILRB1 demonstrated a protective effect in RHD (OR = 0.833, 95% confidence interval, 0.699-0.993). Comparative Toxicogenomics Database analysis identified several small molecules influencing LILRB1 mRNA expression, with lipopolysaccharide showing excellent binding affinity in molecular docking with LILRB1 against available structural data for drugs and proteins. Based on a cohort of European ancestry, this study reveals 13 potential therapeutic targets for RHD, with LILRB1 showing particularly promising prospects as a future therapeutic target for RHD.

Traumatic brain injury (TBI) represents a major cause of mortality and disability worldwide, particularly affecting young adults and elderly populations. This study investigates the neuroprotective potential of orlistat (ORL), a gastrointestinal lipase inhibitor, in a murine TBI model. Behavioral, histological, and molecular analyses demonstrated that ORL significantly attenuated TBI-induced neurological damage. Microglial depletion experiments revealed that ORL's neuroprotective effects were largely mediated through microglial modulation. In vitro and in vivo studies showed that ORL suppressed microglial activation, phagocytosis, and migration. Single-cell RNA sequencing identified upregulation of lipoprotein lipase (LPL) in a TBI-induced microglial subpopulation. Molecular docking predicted ORL-LPL binding, suggesting direct enzymatic inhibition. Transcriptomic and metabolomic analyses further revealed ORL's modulation of microglial metabolic pathways and inflammatory responses. Our findings position ORL as a promising repurposed therapeutic for TBI through its novel mechanism of targeting microglial LPL-mediated neuroinflammation. Show less

Sepsis is a severe systemic infection that can result in organ dysfunction and mortality. Dyslipidemia emerges as a key player in the intricate web of sepsis pathogenesis. Yet, the causal relationship between blood lipid profiles and sepsis risk remains uncertain. This study aims to investigate the association between genetically predicted lipid traits, drug targets, and sepsis. The UK Biobank's Genome-wide association studies (GWAS) produced data on lipid and apolipoprotein characteristics. Four independent GWAS datasets were used to generate the sepsis statistics. The study utilized the two-sample Mendelian randomization (MR) approach, which incorporates multivariable (MVMR) models, to assess the correlations between sepsis risk and lipid-related parameters. To gain further insight, expression quantitative trait loci (eQTL) data were used to investigate the significant drug targets for lipid-lowering. Increasing ApoA-1 levels was associated with a diminished risk of sepsis (under 75) (OR 0.927, 95% CI 0.861-0.999; p = 0.047). This inverse correlation persevered even after performing multivariable MR. Elevated levels of HDL-C were associated with a decreased risk of sepsis (under 75) (OR 0.897, 95% CI 0.838-0.960; P = 0.002) and incidence of sepsis (OR 0.883, 95% CI 0.820-0.951; P = 0.001), which was consistent across sensitivity analyses. Furthermore, a decrease in total cholesterol exhibited a causal effect on sepsis in multivariable MR (OR 0.779, 95% CI 0.642-0.944; P = 0.01). The genetic variants related to lowering LDL-C, located near the HMGCR and LDLR genes, were predicted to elevate the risk of sepsis. Moreover, genetic mimicry near the ANGPTL3 and LPL gene suggested that reducing the activity of ANGPTL3 and LPL (mimicking antisense anti-ANGPTL3 and LPL agents) was forecasted to decrease sepsis risk. Genetically inferred elevated ApoA-1, total cholesterol, and HDL-C manifest a protective effect against sepsis. Within the 9 lipid-lowering drug targets investigated ANGPTL3 and LPL exhibit potential as candidate drug targets for sepsis. Show less

Goat milk is prized for its nutritional value, but the illegal addition of δ-decanolactone to enhance flavor poses risks to product integrity and safety. This study employed a tripartite multi-omics framework integrating metabolomics, lipidomics, and proteomics, combined with FTIR and CLSM to systematically elucidate the multifaceted effects of δ-decanolactone on goat milk. Chemometric and bioinformatic pipelines identified dysregulated molecules and pathways, while molecular docking validated interactions with key targets. δ-Decanolactone modifies the secondary structure of proteins, reducing α-helix by 18.3 % and increasing β-sheet by 38.1 %, while concurrently disrupting the integrity of milk fat globule membrane, compromising the emulsifying and functional properties. Multi-omics profiling revealed around 166 metabolites, 378 lipids, and 41 proteins were dysregulated at the high δ-decanolactone exposure. Joint analysis highlights that δ-decanolactone perturbs in amino acid-fatty acid-phospholipid axis via down-regulating PLIN2, FABP3, and LPL levels, and up-regulating B4GALT1 and XDH levels. Molecular docking confirmed stable interactions between δ-decanolactone and key enzymes, linking the observed structural and functional impairments. These findings establish δ-decanolactone as a multifunctional disruptor of goat milk matrix integrity, driving metabolic rewiring and structural collapse. The identified biomarkers provide actionable tools for adulteration monitoring, supporting stricter regulatory policies and optimized dairy processing to safeguard nutritional quality and consumer safety.

Halide perovskite nanomaterials have emerged as a transformative platform for generating and manipulating polarized luminescence, offering unprecedented opportunities for next-generation optoelectronic technologies. This review comprehensively examines recent advances in engineering both linearly polarized luminescence (LPL) and circularly polarized luminescence (CPL) from perovskite nanostructures, focusing on structural design principles, chirality transfer mechanisms, and performance optimization strategies. Methods are systematically analyzed to achieve polarized emission, including anisotropic nanocrystal growth, chiral ligand functionalization, and liquid crystal-mediated alignment, while highlighting critical optical factors such as dissymmetry factors and photoluminescence quantum yield. Key challenges in enhancing the precision control over perovskite nanostructures, room-temperature CPL efficiency, and scalable assembly are discussed, with a forward-looking perspective on the integration of artificial intelligence (AI) to accelerate progress in the development of perovskite nanomaterials with customized polarized luminescence. By bridging fundamental insights with technological applications, this review outlines a roadmap for developing perovskite-based polarized light sources that combine high performance, stability, and manufacturability, which are key enablers for the future of quantum photonics, ultra-secure communication, and intelligent optical systems.

To reveal the molecular basis of knee osteoarthritis (KOA) with Yang deficiency and blood stasis syndrome by analyzing the gene expression profiles in synovial fluid and blood of KOA patients with this syndrome. A total of 80 KOA patients were recruited from October 2022 to June 2024, including 40 cases in the non- Logistic regression analysis showed that compared with KOA patients with non-Yang deficiency and blood stasis syndrome, those with Yang deficiency and blood stasis syndrome had increased BMI, LDL, fibrinogen, total cholesterol, and D-dimer, and decreased HDL, with a clear correlation between the two groups. There were 562 differential genes in the blood, among which 322 were up-regulated and 240 were down-regulated;755 differential genes were found in the synovial fluid, with 350 up-regulated and 405 down-regulated. KEGG signaling pathway analysis of synovial fluid revealed changes in lipid metabolism-related pathways, including cholesterol metabolism, fatty acid metabolism, and PPARG signaling pathway. Analysis of the involved differential genes identified 6 genes in synovial fluid that were closely related to lipid metabolism, namely LRP1, LPL, ACOT6, TM6SF2, DGKK, and PPARG. Subsequently, PCR and immunohistochemical verification were performed using synovial fluid and cartilage samples, and the results were consistent with those of microarray sequencing.

To date, extensive research has shown that heat stress disturbs glucose and lipid metabolism in broiler chickens. Recent evidence suggests that chromium supplementation influences metabolic regulation, particularly in glucose and lipid homeostasis in mammals. This study aimed to evaluate the effects of chromium picolinate supplementation on glucose and lipid metabolism in the breast muscle of broiler chickens under chronic heat stress. A total of 180 male Arbor Acres (AA) broilers (22 days old) were randomly assigned to three groups: a thermoneutral control group (21°C), a heat stress group (31°C), and a heat stress group receiving chromium picolinate (31°C + 400 μg/Kg elemental chromium). After 14 days, heat stress significantly impaired growth performance, induced insulin resistance, increased fat deposition, and suppressed the expression of key glucose and lipid metabolic genes. In contrast, chromium picolinate improved the average daily feed intake (ADFI), average daily gain (ADG), and reduced feed conversion ratio (FCR). It also upregulated glucose metabolism genes (GLUT1, PI3K, GS) and lipid metabolism genes (PPARα, CPT-1, LPL) in breast muscle. Overall, chromium picolinate alleviated heat stress-induced skeletal muscle glucose and lipid metabolism disturbances in broiler chickens. Show less

Iodine excess reduced serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels during lactation. Iodine deficiency had no significant effect on blood lipid indicators. In early and late lactation, iodine deficiency and excess inhibited triglyceride (TG) levels in milk; in mid-lactation, the inhibitory effect of iodine deficiency was attenuated. Under iodine deficiency and excess, the level of TG and the expression of THRα1, THRβ1, ACC1, FAS, THRSP, BTN1A1, and ADFP proteins in the mammary gland were decreased during lactation; a decrease in LPL protein expression was observed in early and late lactation; and a decline of XOR protein expression was reported in mid and late lactation. Blood lipid metabolism was less sensitive to iodine deficiency during lactation. Iodine excess has a more profound effect on blood lipid metabolism, causing dyslipidemia in lactating rats. Long-term iodine deficiency and excess may have a negative role in the mechanisms regulating milk lipid synthesis and secretion by affecting thyroid hormones to inhibit the milk TG level. Show less

The size of fat globules in ruminant milk to some extent affects the nutritional quality of dairy products and plays potential roles in infant and adult health. Lipid droplets (LD) in mammary epithelial cells are the precursors of milk fat globules (MFG). However, it is unclear what happens to proteins during the transformation process from LD to MFG, and little is known about the regulation of LD diameter in vivo. In this study, 12 mid-lactation Saanen dairy goats were randomly divided into 2 groups: a control group fed a basal diet and an experimental group fed a basal diet supplemented with CLA at 90 g/d. Goat milk was collected for analysis of composition and MFG size. Mammary gland tissue was collected for analysis of LD diameter and proteins. The size of MFG was found to depend on LD diameter in the mammary glands of dairy goats. The regression equations for MFG size (Y) and LD diameter (x) were Y Show less

Kidney Yang Deficiency (KYD) is a metabolic disorder associated with kidney damage. Its slow progression means that causative factors and effective therapeutic agents remain unclear. Extensive evidence links KYD to gut microbiome metabolic diseases and the Hypothalamic-Pituitary-Thyroid (HPT) axis. CDG was extracted from both raw and processed CD and analyzed via HPLC. Propylthiouracil-induced KYD rats were used to assess pharmacological effects, including serum levels of T Fecal non-targeted metabolomics identified 98 metabolites associated with KYD, while 16S rRNA sequencing revealed 13 key intestinal microbiotas linked to KYD. CDG therapy effectively alleviated KYD symptoms by modulating the gut microbiota, improving metabolic and microbial imbalances in KYD. RG/WG significantly improves KYD rats mainly through the relationship between the intestinal microbiota and arachidonic acid metabolism. The key bacterial genera This integrative approach of gut microbiome and fecal metabolomics not only provides a scientific basis for CDG's preventive effects on KYD via the HPT axis but also elucidates the potential mechanisms underlying CDG's action against KYD.

This study focuses on the impacts of polystyrene/polylactic acid microplastics (PS/PLA-MPs) on ovarian reserve and oocyte maturation in female mice, along with the underlying mechanisms. 1 μm PS-MPs and PLA-MPs were prepared, with PLA-MPs having a rougher surface and broader size distribution. In vitro, PLA-MPs showed higher cytotoxicity to granulosa cells compared to PS-MPs. In vivo, MPs exposure disrupted the estrous cycle, and damaged ovarian reserve. Granulosa cell apoptosis and cytokine activation led to transzonal projection retraction, oocyte oxidative stress, meiotic abnormalities, and reduced oocyte retrieval and polar body extrusion rate, thus reducing litter size. PS-MPs induced more severe intestinal and ovarian impairment. Analysis of feces 16S rRNA, serum metabolomics, and ovarian RNA sequencing revealed that lipoprotein lipase (LPL) was suppressed by both MPs, linking gut microbiota, lipid metabolism, and ovarian injury. Fecal microbiota transplantation as a rescue strategy in MPs exposed mice upregulated LPL, alleviating ovarian reserve decline. In PLA-MPs exposed mice, ovarian reserve related indicators partially recovered after a two-week exposure cessation. These results clarify the similarities and differences in how PS-MPs and PLA-MPs impair ovarian function via gut-ovary axis and lipid metabolism dysregulation. Show less

The development of unconventional oil and gas resources is increasingly shifting toward heterogeneous reservoirs with complex permeability distributions, making the effective control of hydraulic fracture propagation patterns critical for optimizing production. To this end, this study establishes a 3D multilayered heterogeneous reservoir model using the finite element method to analyze fracture mechanisms. The impacts of permeability heterogeneous, injection rate, and fracturing fluid viscosity on fracture morphology are systematically investigated, and the elasticity coefficient method was used to evaluate the influence weights of each parameter.The main conclusions are as follows: (1) Permeability distribution is the core factor controlling the fracture propagation direction, with HPL dominating the extension path while MPL and LPL show limited efficiency. (2) An increase in the number of permeability layers inhibits the overall expansion of cracks, and the shape of the cracks gradually changes to rectangular. (3) Higher injection rates significantly expand fracture area, whereas fracturing fluid viscosity ≥50 mPa·s stabilizes fracture morphology. (4) The elastic coefficient method identifies injection rate, permeability heterogeneous, and fracturing fluid viscosity as the key control parameters in order. This work provides theoretical guidance for optimizing hydraulic fracturing parameters in complex geological settings. Show less

Integration of human genomics and other omics across different ancestries provides novel, affordable, and systematic approach for target identification. We used Mendelian randomization approaches to unravel causal associations between 2,940 circulating proteins and 19 CVD. We found 218 proteins that impacted risk of one or more CVDs through forward MR (106 and 182 using cis-pQTLs only and cis- + trans-pQTLs, respectively), among which 107 were previously reported as associated with CVD or CVD-related traits. There were 102 proteins replicated (FDR < 5%, 53 with cis-pQTLs only and 88 with cis- + trans-pQTLs) using the FinnGen Olink data. BTN3A2 was highlighted as a novel candidate gene for ischemic stroke, suggesting a crosstalk between immune modulation and stroke pathogenesis. Single cell integration prioritized PAM for stable angina pectoris and ventricular arrhythmia and LPL for peripheral artery disease, whose transcriptional expressions were enriched in cardiomyocytes. Forward and reverse MR found largely non-overlapping proteins (only 2 overlapped: LGALS4 and MMP12), suggesting distinct proteomic causes and consequences of CVD. Our study provides human genetics-based evidence of novel candidate genes, a foundational step towards full-scale causal human biology-based drug discovery for CVD. Show less

Fructose metabolism is linked to metabolic dysfunction-associated steatotic liver disease (MASLD), but the regulatory mechanisms governing fructose uptake remain poorly understood. Here, we demonstrate that MASLD livers exhibit increased uptake of fructose-derived carbons compared to healthy livers and identify that the MASLD hepatocyte secretome can increase fructose metabolism. By performing fractionation and untargeted proteomics, we uncover a role for Angiopoietin-like 3 (ANGPTL3) as a regulator of hepatic fructose metabolism, independent of its role as a lipoprotein lipase (LPL) inhibitor. Circulating ANGPTL3 levels increase in response to fructose exposure, consistent with an action as a fructose sensor. Angptl3 knockdown in the liver resulted in a significant reduction in the uptake of hepatic fructose metabolites in vivo and downregulation of the facilitative hepatic fructose transporter slc2a8 (GLUT8) and fructolysis enzymes. This work demonstrates the existence of extracellular control of hepatic fructose metabolism through ANGPTL3. Show less
