Background
Obesity-induced adipose tissue expansion is characterized by capillary rarefaction and hypoxia, which disrupts angiogenesis and impairs beige adipogenesis. While angiogenesis is known to be crucial for beiging, the functional link between impaired vascularization and defective browning remains poorly understood. How natural compounds like berberine (BBR) links angiogenesis with beige adipogenesis remains unexplored.
Methods
Using both diet-induced obese (DIO) C57BL/6 J and leptin-deficient (ob/ob) murine models, we administered intraperitoneal BBR for 4 weeks. Adipose tissue remodeling was evaluated through histomorphometry, immunofluorescence, and flow cytometry. RNA sequencing of adipose tissue was performed to identify the potential targets. Chemical hypoxia was induced using CoCl₂ in preadipocytes to examine its effects on browning.
Results
BBR improved adipose tissue dysfunction in both the DIO model and the ob/ob model. It increased CD34+CD31+ endothelial progenitor cells and enhanced protein levels of VEGF/VEGFR2, PRDM16, PPAR-γ, and UCP-1, indicating simultaneous promotion of angiogenesis and adipose browning. Transcriptomic analysis revealed glutathione peroxidase 3 (GPx3) as a novel target through which BBR alleviates adipose dysfunction. GPX3 knockdown in vivo impaired angiogenesis and suppressed browning markers. BBR reversed chemical hypoxia-induced impairment of beige adipocyte differentiation independently of UCP-1 upregulation by inhibiting HIF-1α activation.
Conclusions
This study unveils that BBR counteracts obesity-associated adipose tissue dysfunction: it upregulates GPx3 to reduce oxidative stress, which in turn normalizes HIF-1α levels and activates the PRDM16 signaling, thereby concurrently restoring adipose angiogenesis and promoting beige adipogenesis. This breaks the vicious cycle of hypoxia-impaired angiogenesis and suppressed thermogenesis, positioning BBR as a promising multi-target therapy for obesity.

Background
Polygoni Multiflori Radix (PMR) and its processed form, Polygoni Multiflori Radix Praeparata (PMRP), are two widely used traditional Chinese medicines (TCM). However, in recent years, frequent reports have emerged regarding their hepatotoxicity. Despite numerous studies, the underlying mechanisms of hepatotoxicity and key toxic components remain poorly understood.
Purpose
This study aimed to comprehensively elucidate the hepatotoxic processes of PMR and PMRP and identify the principal toxic components.
Methods
In vivo toxicity tests were carried out to assess the toxicity levels and characteristics of PMR and PMRP. The integration of untargeted serum metabolomics, liver spatial transcriptomics, and liver spatial metabolomics was first employed to elucidate the toxicity mechanisms, which were further validated through metabolite and sensitive index levels and by evaluating protein expression. Mass spectrometry and cytotoxicity tests were utilised to determine the primary toxic components.
Results
The findings revealed that PMR and PMRP primarily regulate tryptophan metabolism, the tricarboxylic acid (TCA) cycle, purine metabolism, and glutathione metabolism. Furthermore, PMR and PMRP can inhibit the expression of bile acid transporters, causing obstruction of bile acid secretion. These modulations trigger oxidative stress, which subsequently leads to cholestasis. The accumulation of bile acids further intensifies oxidative stress, creating a vicious cycle. Furthermore, emodin was identified as the primary toxic component.
Conclusion
PMR and PMRP can induce cholestatic liver injury. They exert hepatotoxic effects by establishing a vicious cycle between cholestasis and oxidative stress, with emodin being the key component responsible for this toxicity.

Background
Semen Sojae Praeparatum (SSP) exhibits both preventive and therapeutic effects against drug-induced liver injury (DILI). Traditionally, SSP is used in combination with Gardeniae fructus to prevent its hepatotoxicity. Isoflavones, the primary components of SSP, can mitigate DILI induced by chemotherapeutic agents such as acetaminophen and cisplatin. However, the potential of SSP to alleviate the hepatotoxicity of triptolide (TP, a prototypical compound in DILI research) remains unexplored.
Purpose
This study aimed to explore the protective effects and potential mechanisms of SSP on TP-induced liver injury.
Methods
The phytochemical profile of the SSP extracts was characterized using UPLC-Q-TOF-MS. Hepatoprotective effects of SSP were assessed using a TP-induced liver injury mouse model. The mechanisms were predicted by metabolomic and proteomic analyses, and further elucidated by RT-qPCR, western blotting and transmission electron microscopy.
Results
Isoflavones were identified as the main components of the SSP extracts. SSP treatment alleviated TP-induced abnormalities in serum biochemical markers, liver index and pathological damage. Multi-omics analysis revealed SSP modulated bile acid (BA) metabolism and autophagy, with Keap1 serving as a core protein. Furthermore, SSP reduced intrahepatic BA accumulation by enhancing hepatic BA transport rather than inhibiting BA synthesis. Additionally, SSP reversed TP-induced abnormalities in Keap1 and p62 expression and nuclear translon cation of the Nrf2 transcription factor, and mitigated oxidative imbalance and autophagic cell death.
Conclusions
SSP ameliorated TP-induced liver injury by modulating bile acid homeostasis and the Keap1/Nrf2/p62 pathway, thereby alleviating oxidative stress and excessive autophagy.

Background
Distant metastasis of colorectal cancer (CRC) is strongly driven by metabolic reprogramming and epithelial–mesenchymal transition (EMT). Increasing evidence suggests that these two processes form a reinforcing positive feedback loop; however, the integrated regulatory mechanism and its potential for pharmacological intervention remain insufficiently understood.
Objective
This study aimed to elucidate the mechanistic coupling between autophagy, metabolic reprogramming, and EMT, and to develop a targeted pharmacological strategy capable of disrupting this positive feedback loop.
Study Design
We systematically constructed and validated an autophagy–metabolism–phenotypic transformation regulatory axis centered on ATG4B and PKM2, and evaluated the therapeutic efficacy of Curcumol as a pathway-specific natural compound intervention.
Methods
Biochemical assays, protein–protein interaction analyses, and functional experiments were performed to determine how ATG4B regulates PKM2 Tyr105 phosphorylation, nuclear translocation, and glycolytic activity. Curcumol was applied to assess its ability to activate ATG4B-dependent autophagy and inhibit PKM2 activation. Anti-tumor efficacy was validated using colorectal cancer organoids, orthotopic implantation, and liver metastasis mouse models.
Results
ATG4B was identified as a core autophagy enzyme that directly binds to and shields the PKM2 Tyr105 site, preventing FGFR1-mediated phosphorylation and nuclear translocation. This blockade suppressed the Warburg effect, reduced lactate production, and synergistically inhibited EMT progression. Curcumol activated ATG4B-dependent autophagy, inhibited PKM2 activation, and effectively disrupted the metabolism–EMT positive feedback loop. In multiple CRC models, Curcumol markedly suppressed tumor growth and metastasis, supporting its therapeutic potential.
Conclusion
This study reveals the ATG4B–PKM2 axis as a critical regulatory node linking autophagy, metabolic reprogramming, and EMT. Targeting this axis with Curcumol provides a precise strategy to interrupt metabolism–phenotype coupling, offering a mechanistically grounded and translationally promising approach for inhibiting CRC progression and metastasis.

Background
Sepsis-induced acute liver injury (SALI) remains a major challenge with limited effective treatments. Although Corydalis saxicola Bunting (CSB) exhibits anti-inflammatory and hepatoprotective properties, its role in SALI remains poorly understood.
Purpose
To identify the active components and molecular mechanisms of CSB in protecting against SALI.
Methods
In vivo LPS-induced rat liver injury and in vitro cytokine-induced HepG2 injury models were established, treated with CSB extract or dehydrocavidine (DC). A series of advanced techniques including ferroptosis PCR array, super-resolution stimulated emission depletion (STED) microscopy, assay for transposase-accessible chromatin with sequencing (ATAC-seq), cellular thermal shift assay (CETSA), surface plasmon resonance (SPR), molecular dynamics simulation, and site-directed mutation were employed to investigate the underlying mechanisms.
Results
DC significantly mitigated LPS-induced liver injury, microcirculatory disorder, and leukocyte adhesion. It also alleviated liver ferroptosis under LPS challenge. In vitro studies revealed that LPS-activated macrophages secreted tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), which triggered hepatocyte ferroptosis. DC countered this process by inhibiting the production of these cytokines and correcting cytokine-induced mitochondrial abnormalities in hepatocytes. Mechanistically, DC bound to Kelch-like ECH-associated protein 1 (Keap1) at arginine 415 (R415), disrupting the formation of the Keap1/nuclear factor erythroid 2-related factor 2 (Nrf2) complex. This enabled Nrf2 nuclear translocation and promoted antioxidant gene expression, thereby correcting LPS-induced redox imbalance in hepatocytes.
Conclusions
In addition to inhibiting LPS-induced macrophage activation, DC activates the Nrf2 signaling pathway in hepatocytes to alleviate inflammation-enhanced liver ferroptosis. It provides potential therapeutic strategies for sepsis and Gram-negative bacteria-associated liver injury.

Background
Metabolic associated fatty liver disease (MAFLD) is a chronic liver condition with a high global prevalence. Obesity and its associated insulin resistance are among the main risk factors for MAFLD, for which no effective clinical treatments are currently available. Aloesin, a natural chromone compound derived from Aloe vera, has anti-inflammatory, antioxidant, anticancer, and antidiabetes activity. However, its involvement in MAFLD has not been systematically studied.
Purpose
This study investigated the effectiveness of aloesin against MAFLD and obesity and elucidated its potential molecular mechanism.
Methods
Aloesin was added to the high-fat diet-of an induced mouse model and to oleic acid/palmitic acid-induced HepG2 cells to explore its effect on lipid metabolism. Molecular targets were identified by reverse docking, cellular thermal shift assay (CETSA), and drug affinity responsive target stability (DARTS).
Results
Aloesin significantly reduced lipid accumulation in hepatocytes in both the high-fat diet-induced MAFLD mouse model and the oleic acid/palmitic acid-induced HepG2 cells. It also alleviated oxidative stress and energy metabolism disorders and decreased the body fat mass in mice fed the high-fat diet, which ameliorated the pathological features of MAFLD and obesity. Target prediction and validation identified TGFBR1 as a direct target of aloesin, which was confirmed by CETSA and DARTS. Functional experiments demonstrated that overexpression of TGFBR1 increased lipid accumulation and metabolic disturbances, which were reversed by aloesin.
Conclusion
Aloesin improved lipid deposition and slowed the progression of MAFLD by targeting TGFBR1. The results support its potential application for the prevention and treatment of MAFLD.

Background
Diabetic retinopathy (DR) pathogenesis is driven by the dysregulation of an interconnected network of regulated cell death (RCD) modalities, including apoptosis, autophagy-dependent cell death, pyroptosis, and ferroptosis. Current therapies often fail to address this upstream cellular damage. Natural products (NPs), with their inherent polypharmacology, offer a promising strategy to modulate this complex network.
Purpose
This review advances a framework conceptualizing DR as the collapse of a dynamic RCD network and positions NPs as "RCD network modulators". We delineate how these agents can restore homeostasis and overcome the limitations of existing mono-target therapies.
Methods
A systematic literature search was conducted using Web of Science and PubMed, integrating keywords related to "natural products", "diabetic retinopathy", and specific "regulated cell death" modalities. All animal experiments adhered to ethical guidelines and complied with both international and institutional ethical standards.
Results
NPs simultaneously engage the master regulatory nodes—mitochondrial dysfunction, hyperactivation of the inflammasome, and oxidative stress. By modulating the Bcl-2 rheostat, normalizing autophagic flux, suppressing NLRP3 assembly, and activating Nrf2/SIRT1 pathways, NPs orchestrate a "network rewiring" to halt DR progression. However, clinical translation is significantly constrained by pharmacokinetic challenges, including low oral bioavailability and poor ocular penetration.
Conclusion
DR pathology emerges from network-level RCD dysregulation. NPs, which function as modulators of the RCD network, represent a compelling therapeutic shift toward addressing the root drivers of retinal degeneration.
背景:糖尿病视网膜病变(DR)的发病机制是由一个相互关联的细胞死亡(RCD)模式网络的失调驱动的,包括细胞凋亡、自噬依赖性细胞死亡、焦亡和铁亡。目前的治疗方法往往不能解决这种上游细胞损伤。天然产物(NPs)以其固有的多药理学,为调节这一复杂网络提供了一种有前途的策略。目的:本文提出了一个框架,将DR概念化为动态RCD网络的崩溃,并将NPs定位为“RCD网络调制器”。我们描述了这些药物如何恢复体内平衡并克服现有单靶点治疗的局限性。方法:利用Web of Science和PubMed进行系统文献检索,整合“天然产物”、“糖尿病视网膜病变”和特定“调节细胞死亡”方式等相关关键词。所有动物实验均遵循伦理准则,符合国际和机构的伦理标准。结果:NPs同时参与主要调控节点——线粒体功能障碍、炎性体过度激活和氧化应激。通过调节Bcl-2变阻器,使自噬通量正常化,抑制NLRP3组装,激活Nrf2/SIRT1通路,NPs协调“网络重新布线”以阻止DR进展。然而,临床翻译明显受到药代动力学挑战的限制,包括口服生物利用度低和眼穿透性差。结论:网络水平的RCD失调导致了DR病理。NPs作为RCD网络的调节剂,代表了一个引人注目的治疗转变,以解决视网膜变性的根本驱动因素。
