ObjectiveTo investigate the therapeutic mechanism of Xuefu Zhuyutang (XFZYT) for metabolic-associated fatty liver disease (MAFLD) through integrated network pharmacology and animal experiments. MethodsNetwork pharmacology was utilized to predict the core components, key therapeutic targets, and signaling pathways of XFZYT in the treatment of MAFLD. For animal experiments, a rat model of MAFLD was established by feeding a high-cholesterol diet for 4 weeks. Intervention was then administered with low-dose (2 g·kg-1) and high-dose (4 g·kg-1) XFZYT for 2 weeks. Biochemical assays were performed to measure the serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL). In addition, the activities of superoxide dismutase (SOD) and catalase (CAT) and levels of malondialdehyde (MDA) and glutathione (GSH) in the serum were measured. The same way was adopted to measure the levels of TC and TG in the liver tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to quantify the serum levels of interleukin (IL)-6, IL-1β, and tumor necrosis factor-alpha (TNF-α). Histopathological evaluations included hematoxylin and eosin (HE) staining for liver tissue morphology, Oil Red O staining for lipid deposition, and dihydroethidium (DHE) probe staining for reactive oxygen species (ROS) levels. Western blot analysis was conducted to assess the protein levels of AMP-activated protein kinase (AMPK), phosphorylated (p)-AMPK, nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), nuclear factor-kappa B (NF-κB), and p-NF-κB in the liver tissue. Untargeted metabolomics analysis of the serum was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). ResultsNetwork pharmacology analysis predicted 155 potential targets of XFZYT for MAFLD treatment, with core targets including signal transducer and activator of transcription 3 (STAT3), protein kinase B1 (Akt1), TNF, and IL-6. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment primarily implicated the AMPK signaling pathway. Animal experiments demonstrated that compared with the normal group, the model group exhibited dyslipidemia, hepatic function impairment, pronounced hepatic lipid deposition, and inflammatory manifestations, with elevated serum levels of AST, ALT, TC, TG, LDL, and MDA (P<0.05), reduced HDL and GSH levels plus decreased SOD and CAT activities (P<0.05), downregulated protein levels of Nrf2, HO-1, and p-AMPK (P<0.05), and upregulated protein level of p-NF-κB (P<0.05) in the liver tissue. Compared with the model group, XFZYT intervention groups showed significant amelioration of dyslipidemia and hepatic function impairment, markedly reduced hepatic lipid deposition and inflammatory cell infiltration, decreased serum levels of AST, ALT, TC, TG, LDL, and MDA (P<0.05), increased HDL and GSH levels plus enhanced SOD and CAT activities (P<0.05), upregulated protein levels of Nrf2, HO-1, and p-AMPK (P<0.05), and downregulated protein level of p-NF-κB (P<0.05). Serum metabolomics revealed 511 differentially expressed metabolites (231 upregulated and 280 downregulated) between normal and model groups, while XFZYT groups versus model group showed 94 differential metabolites (51 upregulated and 43 downregulated). Among them, 11 metabolites displayed the most significant alterations, with enriched pathways including glycerolipid metabolism, cholesterol metabolism, and insulin resistance, multiple of which demonstrated AMPK association. ConclusionXFZYT alleviates MAFLD by regulating the AMPK signaling pathway and associated metabolic networks.

Thoracic aortic aneurysm(TAA)significantly endangers the lives of individuals with Marfan syndrome(MFS),yet the intricacies of their biomechanical origins remain elusive.Our investigation delves into the pivotal role of hemodynamic disturbance in the pathogenesis of TAA,with a particular emphasis on the mechanistic contributions of the mammalian target of rapamycin(mTOR)signaling cascade.We un-covered that activation of the mTOR complex 1(mTORC1)within smooth muscle cells,instigated by the oscillatory wall shear stress(OSS)that stems from disturbed flow(DF),is a catalyst for TAA progression.This revelation was corroborated through both an MFS mouse model(Fbn1+/C1039G)and clinical MFS specimens.Crucially,our research demonstrates a direct linkage between the activation of the mTORC1 pathway and the intensity in OSS.Therapeutic administration of rapamycin suppresses mTORC1 activity,leading to the attenuation of aberrant SMC behavior,reduced inflammatory infiltration,and restoration of extracellular matrix integrity—collectively decelerating TAA advancement in our mouse model.These insights posit the mTORC1 axis as a strategic target for intervention,offering a novel approach to manage TAAs in MFS and potentially pave insights for current treatment paradigms.

As an important tissue of the body(accounting for approximately 40%of body weight),skel-etal muscle is composed of various cell types such as muscle fibers,muscle stem cells,and endothelial cells.It participates in physiological processes including movement,energy metabolism,and internal en-vironment homeostasis through temporal and spatial specific regulation.Its development is divided into two critical stages:embryonic and postnatal periods.Abnormal development can lead to diseases such as muscular dystrophy and directly affect the yield and quality of livestock meat.In recent years,the combi-nation of single-cell transcriptomics(scRNA-seq)and spatial omics(single-cell spatial omics technolo-gy)has provided a high-resolution research tool for analyzing the spatiotemporal dynamic regulatory net-work and intercellular interactions in skeletal muscle development.This article reviews the molecular mechanisms of skeletal muscle development and its application value in animal husbandry breeding,and systematically combs the research progress,analysis processes,data resources,and future directions of single-cell omics,spatial omics,and single-cell spatial omics technology in skeletal muscle development.Among them,single-cell omics can reveal the heterogeneity of skeletal muscle cells,myofiber differentia-tion trajectories in different livestock and poultry(such as cattle,pigs,and Tibetan chickens)through methods like pseudotime analysis and RNA velocity analysis.Furthermore,single-cell omics can identify key transcription factors(e.g.,MYF5,MYOD1)and cell communication pathways(e.g.,FGF7-FG-FR2),and simultaneously clarify the molecular differences in myoblast differentiation timing and cell composition ratio among different breeds.Relying on technologies such as Visium and Seq-Scope,spatial omics realizes the spatial localization of gene expression in pathological models of mice,Atlantic salmon,and broiler chickens.Spatial omics also clarifies the spatial distribution laws of neuromuscular junction region-specific genes and inflammation-fibrosis cascade reactions,and makes up for the defect of losing spatial context in single-cell technology.Although there are limited direct application cases of single-cell spatial omics technology,it has already analyzed the abnormal fate of myoblasts in facioscapulohumeral muscular dystrophy through MERFISH technology.In terms of technology selection,it is necessary to consider research objectives,molecular modalities,and resolution requirements.At the same time,data analysis needs to address challenges such as data sparsity through methods like DCA denoising and RCTD cell type mapping.In addition,this article summarizes 16 muscle development-related databases inclu-ding HCA and PanglaoDB.This review further discusses the potential applications of these three types of technologies in the directional regulation of myoblast fate,precise intervention in the growth cycle,im-provement of microenvironment interactions,and the development of multi-omics genetic breeding mod-els.This paper is providing a more comprehensive and detailed theoretical reference and technical sup-port for basic research on skeletal muscle development and practical applications in the animal husbandry industry.
