    940-954页
    查看更多>>摘要：Drug resistance presents a significant challenge to achieving positive clinical outcomes in anti-tumor therapy.Prior research has illuminated reasons behind drug resistance,including increased drug efflux,alterations in drug targets,and abnormal activation of oncogenic pathways.However,there's a need for deeper investigation into the impact of drug-resistant cells on parental tumor cells and intricate crosstalk between tumor cells and the malignant tumor microenvironment(TME).Recent studies on extracellular vesicles(EVs)have provided valuable insights.EVs are membrane-bound particles secreted by all cells,mediating cell-to-cell communication.They contain functional cargoes like DNA,RNA,lipids,proteins,and metabolites from mother cells,delivered to other cells.Notably,EVs are increasingly recognized as regulators in the resistance to anti-cancer drugs.This review aims to summarize the mechanisms of EV-mediated anti-tumor drug resistance,covering therapeutic approaches like chemo-therapy,targeted therapy,immunotherapy and even radiotherapy.Detecting EV-based biomarkers to predict drug resistance assists in bypassing anti-tumor drug resistance.Additionally,targeted inhibition of EV biogenesis and secretion emerges as a promising approach to counter drug resistance.We highlight the importance of conducting in-depth mechanistic research on EVs,their cargoes,and functional ap-proaches specifically focusing on EV subpopulations.These efforts will significantly advance the devel-opment of strategies to overcome drug resistance in anti-tumor therapy.

    Mechanisms and therapeutic targets of ferroptosis:Implications for nanomedicine design

    Meihong ZhangMengqin GuoYue GaoChuanbin Wu...
    955-971页
    查看更多>>摘要：Ferroptosis is a nonapoptotic form of cell death and differs considerably from the well-known forms of cell death in terms of cell morphology,genetics,and biochemistry.The three primary pathways for cell ferroptosis are system Xc-/glutathione peroxidase 4(GPX4),lipid metabolism,and ferric metabolism.Since the discovery of ferroptosis,mounting evidence has revealed its critical regulatory role in several diseases,especially as a novel potential target for cancer therapy,thereby attracting increasing attention in the fields of tumor biology and anti-tumor therapy.Accordingly,broad prospects exist for identifying ferroptosis as a potential therapeutic target.In this review,we aimed to systematically summarize the activation and defense mechanisms of ferroptosis,highlight the therapeutic targets,and discuss the design of nanomedicines for ferroptosis regulation.In addition,we opted to present the advantages and disadvantages of current ferroptosis research and provide an optimistic vision of future directions in related fields.Overall,we aim to provide new ideas for further ferroptosis research and inspire new strategies for disease diagnosis and treatment.

    Non-coding RNAs as therapeutic targets in cancer and its clinical application

    Xuejiao LengMengyuan ZhangYujing XuJingjing Wang...
    983-1010页
    查看更多>>摘要：Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

    Dual mass spectrometry imaging and spatial metabolomics to investigate the metabolism and nephrotoxicity of nitidine chloride

    Shu YangZhonghua WangYanhua LiuXin Zhang...
    1011-1023页
    查看更多>>摘要：Evaluating toxicity and decoding the underlying mechanisms of active compounds are crucial for drug development.In this study,we present an innovative,integrated approach that combines air flow-assisted desorption electrospray ionization mass spectrometry imaging(AFADESI-MSI),time-of-flight secondary ion mass spectrometry(ToF-SIMS),and spatial metabolomics to comprehensively investi-gate the nephrotoxicity and underlying mechanisms of nitidine chloride(NC),a promising anti-tumor drug candidate.Our quantitive AFADESI-MSI analysis unveiled the region specific of accumulation of NC in the kidney,particularly within the inner cortex(IC)region,following single and repeated dose of NC.High spatial resolution ToF-SIMS analysis further allowed us to precisely map the localization of NC within the renal tubule.Employing spatial metabolomics based on AFADESI-MSI,we identified over 70 discriminating endogenous metabolites associated with chronic NC exposure.These findings suggest the renal tubule as the primary target of NC toxicity and implicate renal transporters(organic cation transporters,multidrug and toxin extrusion,and organic cation transporter 2(OCT2)),metabolic en-zymes(protein arginine N-methyltransferase(PRMT)and nitric oxide synthase),mitochondria,oxidative stress,and inflammation in NC-induced nephrotoxicity.This study offers novel insights into NC-induced renal damage,representing a crucial step towards devising strategies to mitigate renal damage caused by this compound.

    Signal interference between drugs and metabolites in LC-ESI-MS quantitative analysis and its evaluation strategy

    Fulin JiangJingyu LiuYagang LiZihan Lu...
    1024-1034页
    查看更多>>摘要：Liquid chromatography-electrospray ionization tandem mass spectrometry(LC-ESI-MS)is a widely utilized technique for in vivo pharmaceutical analysis.Ionization interference within electrospray ion source,occurring between drugs and metabolites,can lead to signal variations,potentially compromising quantitative accuracy.Currently,method validation often overlooks this type of signal interference,which may result in systematic errors in quantitative results without matrix-matched calibration.In this study,we conducted an investigation using ten different groups of drugs and their corresponding me-tabolites across three LC-ESI-MS systems to assess the prevalence of signal interference.Such in-terferences can potentially cause or enhance nonlinearity in the calibration curves of drugs and metabolites,thereby altering the relationship between analyte response and concentration for quanti-fication.Finally,we established an evaluation scheme through a step-by-step dilution assay and employed three resolution methods:chromatographic separation,dilution,and stable labeled isotope internal standards correction.The above strategies were integrated into the method establishment process to improve quantitative accuracy.

    Pharmacometabolomics and mass spectrometry imaging approach to reveal the neurochemical mechanisms of Polygala tenuifolia

    Qian LiJinpeng BaiYuxue MaYu Sun...
    1035-1046页
    查看更多>>摘要：Polygala tenuifolia,commonly known as Yuanzhi(YZ)in Chinese,has been shown to possess anti-insomnia properties.However,the material basis and the mechanism underlying its sedative-hypnotic effects remain unclear.Herein,we investigated the active components and neurochemical mechanism of YZ extracts using liquid chromatography tandem mass spectrometry(LC-MS/MS)-based pharmaco-metabolomics and mass spectrometry imaging(MSI)-based spatial resolved metabolomics.According to the results,17 prototypes out of 101 ingredients in the YZ extract were detected in both the plasma and brain,which might be the major components contributing to the sedative-hypnotic effects.Network pharmacology analysis revealed that these prototypes may exert their effects through neuroactive ligand-receptor interaction,serotonergic synapse,dopaminergic synapse,and dopaminergic synapse,among other pathways.LC-MS/MS-based targeted metabolomics and Western blot(WB)revealed that tryptophan-serotonin-melatonin(Trp-5-HT-Mel)and tyrosine-norepinephrine-adrenaline(Tyr-Ne-Ad)are the key regulated pathways.Dopa decarboxylase(DDC)upregulation and phenylethanolamine N-methyltransferase(PNMT)downregulation further confirmed these pathways.Furthermore,MSI-based spatially resolved metabolomics revealed notable alterations in 5-HT in the pineal gland(PG),and Ad in the brainstem,including the middle brain(MB),pons(PN),and hypothalamus(HY).In summary,this study illustrates the efficacy of an integrated multidimensional metabolomics approach in unraveling the sedative-hypnotic effects and neurochemical mechanisms of a Chinese herbal medicine,YZ.

    Baicalin reduces chronic stress-induced breast cancer metastasis via directly targeting β2-adrenergic receptor

    Qi JiaYinyin ZhouLi SongXimeng Shi...
    1047-1062页
    查看更多>>摘要：Recent studies have shown that stress can substantially facilitate breast cancer metastasis,which can be reduced by nonselective β1/β2-adrenergic receptor(β1/β2-AR)blocker.However,several side effects were identified.Thus,it is extremely warranted to explore more effective and better-tolerated β2-AR blocker.Currently,we demonstrated that baicalin(BA),a major bioactive component of Scutellaria bai-calensis Georgi,could significantly attenuate stress hormones especially epinephrine(Epi)-induced breast cancer cell migration and invasion in vitro.Mechanistically,we identified that β2-AR was a direct target of BA via the drug affinity responsive target stability(DARTS)combined with mass spectrum assay,and BA photoaffinity probe with pull-down assay,which was further confirmed by a couple of bio-physical and biochemical assays.Furthermore,we demonstrated that BA could directly bind to the Phe-193 and Phe-289 of β2-AR,subsequently inhibit cyclic adenosine monophosphate-protein kinase A-focal adhesion kinase(cAMP-PKA-FAK)pathway,and thus impede epithelial-mesenchymal transition(EMT),thereby hindering the metastatic progression of the chronic stress coupled with syngeneic and xenograft in vivo orthotopic and tail vein mouse model.These findings firstly identify BA as a potential β2-AR inhibitor in the treatment of stress-induced breast cancer metastasis.

    An Fe-Cu bimetallic organic framework as a microwave sensitizer for treating tumors using combined microwave thermotherapy and chemodynamic therapy

    Xinyang ZhuChao HeLongfei TanXun Qi...
    1063-1075页
    查看更多>>摘要：Microwave thermotherapy(MWTT),as a treatment for tumors,lacks specificity and requires sensitizers.Most reported microwave sensitizers are single metal-organic frameworks(MOFs),which must be loaded with ionic liquids to enhance the performance in MWTT.Meanwhile,MWTT is rarely combined with other treatment modalities.Here,we synthesized a novel Fe-Cu bimetallic organic framework FeCuMOF(FCM)by applying a hydrothermal method and further modified it with methyl polyethylene glycol(mPEG).The obtained FCM@PEG(FCMP)showed remarkable heating performance under low-power microwave irradiation;it also acted as a novel nanospheres enzyme to catalyze H2O2 decompo-sition,producing abundant reactive oxygen species(ROS)to deplete glutathione(GSH)and prevent ROS clearance from tumor cells during chemodynamic treatment.The FCMP was biodegradable and demonstrated excellent biocompatibility,allowing it to be readily metabolized without causing toxic effects.Finally,it was shown to act as a suitable agent for T2 magnetic resonance imaging(MRI)in vitro and in vivo.This new bimetallic nanostructure could successfully realize two tumor treatment modalities(MWTTand chemodynamic therapy)and dual imaging modes(T2 MRI and microwave thermal imaging).Our findings represent a breakthrough for integrating the diagnosis and treatment of tumors and pro-vides a reference for developing new microwave sensitizers.
