Abstract
Cancer surgery remains a mainstay in clinical treatment. However, the efficacy of subsequent therapies largely depends on the precise evaluation of postoperative prognoses, underscoring the critical need for a comprehensive and accurate assessment of surgical outcomes. Nanoprobes targeting tumors offer a promising solution for visual prognostic assessment. In this study, we developed a "Spindle Monitor" system, designated as APPADs (Au NBPs@PDA-pep-AS1411-Dox), composed of core-shell nanoparticles. The core was made up of gold nanobipyramids (Au NBPs), coated with polydopamine (PDA), and subsequently loaded with peptide chains, AS1411, and doxorubicin (Dox). Upon deployment in the acidic tumor microenvironment (TME), APPADs released substantial amounts of Dox, initiating the apoptotic process. This triggered the activity of caspase-3, which is a crucial executor in the apoptotic pathway. Consequently, DEVD, a specific recognition site for caspase-3, was cleaved, enabling the disconnection of FITC-conjugated peptide chains and the recovery of fluorescence. Through assessing this fluorescence imaging effect, local laser irradiation could be precisely guided to the postoperative site, facilitating a synergistic combination of photothermal therapy and chemotherapy. Specifically, our "Spindle Monitor" APPADs had been validated to achieve accurate fluorescence imaging in vitro and in vivo, which demonstrated its potential value as a versatile tool for evaluating postoperative prognosis in surgical treatments, such as thyroid cancer, and assessing chemotherapy efficacy in difficult cases, like late-stage osteosarcoma. This promising tool lays a good foundation for development in visual prognosis evaluation after tumor surgery.

Co-delivery of a tumor microenvironment-responsive disulfiram prodrug and CuO 2 nanoparticles for efficient cancer treatment. NANOSCALE ADVANCES 2023; 5:3336-3347. [PMID: 37325521 PMCID: PMC10262962 DOI: 10.1039/d3na00004d] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 05/08/2023] [Indexed: 06/17/2023]
Abstract
Disulfiram (DSF) has been used as a hangover drug for more than seven decades and was found to have potential in cancer treatment, especially mediated by copper. However, the uncoordinated delivery of disulfiram with copper and the instability of disulfiram limit its further applications. Herein, we synthesize a DSF prodrug using a simple strategy that could be activated in a specific tumor microenvironment. Poly amino acids are used as a platform to bind the DSF prodrug through the B-N interaction and encapsulate CuO2 nanoparticles (NPs), obtaining a functional nanoplatform Cu@P-B. In the acidic tumor microenvironment, the loaded CuO2 NPs will produce Cu2+ and cause oxidative stress in cells. At the same time, the increased reactive oxygen species (ROS) will accelerate the release and activation of the DSF prodrug and further chelate the released Cu2+ to produce the noxious copper diethyldithiocarbamate complex, which causes cell apoptosis effectively. Cytotoxicity tests show that the DSF prodrug could effectively kill cancer cells with only a small amount of Cu2+ (0.18 μg mL-1), inhibiting the migration and invasion of tumor cells. In vitro and in vivo experiments have demonstrated that this functional nanoplatform could kill tumor cells effectively with limited toxic side effects, showing a new perspective in DSF prodrug design and cancer treatment.

Abstract
Cell death constitutes an indispensable part of the organismal balance in the human body. Generally, cell death includes regulated cell death (RCD) and accidental cell death (ACD), reflecting the intricately molecule-dependent process and the uncontrolled response, respectively. Furthermore, diverse RCD pathways correlate with multiple diseases, such as tumors and neurodegenerative diseases. Meanwhile, with the development of precision medicine, novel nano-based materials have gradually been applied in the clinical diagnosis and treatment of tumor patients. As the carrier, organic, inorganic, and biomimetic nanomaterials could facilitate the distribution, improve solubility and bioavailability, enhance biocompatibility and decrease the toxicity of drugs in the body, therefore, benefiting tumor patients with better survival outcomes and quality of life. In terms of the most studied cell death pathways, such as apoptosis, necroptosis, and pyroptosis, plenty of studies have explored specific types of nanomaterials targeting the molecules and signals in these pathways. However, no attempt was made to display diverse nanomaterials targeting different RCD pathways comprehensively. In this review, we elaborate on the potential mechanisms of RCD, including intrinsic and extrinsic apoptosis, necroptosis, ferroptosis, pyroptosis, autophagy-dependent cell death, and other cell death pathways together with corresponding nanomaterials. The thorough presentation of RCD pathways and diverse nano-based materials may provide a wider cellular and molecular landscape of tumor diagnosis and treatments.

Abstract
MiRNA-targeted therapy holds great promise for precision cancer therapy. It is important to investigate the effect of changes in miRNA expression on apoptosis in order to evaluate miRNA-targeted therapy and achieve personalized therapy. In this study, we designed a dual-color fluorescent nanosensor consisting of grapheme oxide modified with a molecular beacon and peptide. The nanosensor can simultaneously detect and image miRNA-221 and apoptotic protein caspase-3 in living cells. Intracellular experiments showed that the nanosensor could be successfully applied for in situ monitoring of the effect of miRNA-221 expression changes on apoptosis by dual-color imaging. The current strategy could provide new avenues for investigating the feasibility of miRNA-targeted therapy, screening new anti-cancer drugs targeting miRNA and developing personalized treatment plans.

Abstract
INTRODUCTION Tumor cell apoptosis is a crucial indicator for judging the antiproliferative effects of anti-cancer drugs. The detection of optical and macromolecular biomarkers is the most common method for assessing the level of apoptosis. We aimed to explore the anti-tumor mechanisms of 6-methoxyflavone. MATERIAL AND METHODS Three optical methods, including the percentage of apoptotic cells, cell morphology, and subcellular ultrastructure changes, were obtained using flow cytometry, inverted fluorescence microscopy, and transmission electron microscope imaging. The mRNA or protein expression of macromolecular biomarkers related to common apoptotic pathways was determined via polymerase chain reactions or western blot assays. The functional role of the core gene biomarker was investigated through overexpression, knockdown, and phosphorylation inhibitor (GSK2656157). RESULTS Transcriptome sequencing and the optical biomarkers assays demonstrated that 6-methoxyflavone could induce apoptosis in HeLa cells. The expression of macromolecular biomarkers indicated that 6-methoxyflavone induced apoptosis through the PERK/EIF2α/ATF4/CHOP pathway. Phosphorylated PERK was identified as the core biomarker of this pathway. Both overexpression and GSK2656157 significantly altered the expression level of phosphorylated PERK in 6-methoxyflavone-treated HeLa cells. DISCUSSION AND CONCLUSION Macromolecular biomarkers such as phosphorylated PERK and phosphorylated EIF2α are of great significance for assessing the therapeutic effects of 6-methoxyflavone.

Abstract
We construct a peptide-conjugated metal cluster as an enzyme-like catalytic bioprobe to enhance quantitative analysis of a membrane protein biomarker and detect epithelial-to-mesenchymal transition of tumor cells. This bioprobe with atomically precise formula, termed clusterzyme, possesses selective recognition and intrinsic enzyme-like activity. These favorable features facilitate sensitive quantitative analysis of the membrane protein in situ through on-cell catalytic signal amplification. This clusterzyme-based analytical method exhibits excellent compatibility with a traditional enzyme-linked immunosorbent assay and improved detection sensitivity with accuracy and robustness. Further, the expression level of the membrane protein reflects the ability of migration and invasion of model tumor cells, revealing epithelial-to-mesenchymal transition process. This work offers a facile and sensitive approach to monitor tumor cell type evolution at the molecular level, demonstrating a potential application of early cancer diagnosis and therapy assessment.

Abstract
Phenotypic plasticity is an emerging paradigm for providing biological and clinical insights into cancer initiation, progression, and resistance to therapy. However, it is a great challenge to track phenotypic information on live cells with high levels of sensitivity, specificity, and simplicity, when a specific cancer-cell subset is being targeted. In this work, we have successfully achieved cascade assembly of nanoparticles on the surface of specific cancer cells by designing a dual-aptamer-weaved molecular AND logic system. Taking advantage of spatial addressability, precise controllability, and targeting recognition of the nanostructure assemblies, we can precisely label the target-cell subset in a large population of similar cells and rapidly obtain phenotypic information in response to the surface changes of captured cancer cells. Without sophisticated instruments, we can know the phenotypic information on HepG2 cells in whole blood with a high level of sensitivity and rapid naked-eye tracking of on-cell phenotype changes of HepG2 cells undergoing epithelial-mesenchymal transition.

Abstract
Cancer cell migration and invasion are initial steps for tumor metastasis, which increases patient mortality. The tumor microenvironment is characterized as being hypoxic and nutrient deficient. Previous studies have suggested that hypoxia induces tumor metastasis, while the low nutrient content is not beneficial for tumor metastasis. Thus, it is necessary to develop a simple probe to study the changes in cancer migration and invasion. Herein, we designed a nanoprobe based on gold nanoparticles (Au NPs) to monitor the effect of different oxygen and nutrient conditions on the migration and invasion of breast cancer cells through detecting the changes in levels of RAB-22a and MMP-2 mRNA in living cells. After incubating MCF-7 and MDA-MB-231 cells with different concentrations of oxygen and nutrients, fluorescence imaging assays were used to evaluate migration and invasion. This work provides a new insight in the effect of different tumor microenvironments on cell migration and invasion.

Abstract
Drug resistance developed towards conventional therapy is one of the important reasons for chemotherapy failure in cancer. The various underlying mechanism for drug resistance development in tumor includes tumor heterogeneity, some cellular levels changes, genetic factors, and others novel mechanisms which have been highlighted in the past few years. In the present scenario, researchers have to focus on these novel mechanisms and their tackling strategies. The small molecules, peptides, and nanotherapeutics have emerged to overcome the drug resistance in cancer. The drug delivery systems with targeting moiety enhance the site-specificity, receptor-mediated endocytosis, and increase the drug concentration inside the cells, thus minimizing drug resistance and improve their therapeutic efficacy. These therapeutic approaches work by modulating the different pathways responsible for drug resistance. This review focuses on the different mechanisms of drug resistance and the recent advancements in therapeutic approaches to improve the sensitivity and effectiveness of chemotherapeutics.

Abstract
Epithelial-to-mesenchymal transition (EMT) is an essential molecular and cellular process that is part of normal embryogenesis and wound healing, and also has a ubiquitous role in various types of carcinoma and glioblastoma. EMT is activated and regulated by specific microenvironmental endogenous triggers and a complex network of signalling pathways. These mostly include epigenetic events that affect protein translation-controlling factors and proteases, altogether orchestrated by the switching on and off of oncogenes and tumour-suppressor genes in cancer cells. The hallmark of cancer-linked EMT is that the process is incomplete, as it is opposed by the reverse process of mesenchymal-to-epithelial transition, which results in a hybrid epithelial/mesenchymal phenotype that shows notable cell plasticity. This is a characteristic of cancer stem cells (CSCs), and it is of the utmost importance in their niche microenvironment, where it governs CSC migratory and invasive properties, thereby creating metastatic CSCs. These cells have high resistance to therapeutic treatments, in particular in glioblastoma.

Am J Cancer Res 2020; 10:6384-6398.

Abstract
To circumvent the huge cost, long R&D time and the difficulty to identify the targets of new drugs, repurposing the ones that have been clinically approved has been considered as a viable strategy to treat different diseases. In the current study, we outlined the rationale for repurposing disulfiram (DSF, an old alcohol-aversion drug) to treat primary breast cancer and its metastases. Methods: To overcome a few shortcomings of the individual administration of DSF, such as the dependence on copper ions (Cu2+) and limited capability in selective targeting, we here artificially synthesized the active form of DSF, diethyldithiocarbamate (DTC)-Cu complex (CuET) for cancer therapeutics. To achieve a greater efficacy in vivo, smart nanomedicines were devised through a one-step self-assembly of three functional components including a chemically stable and biocompatible phase-change material (PCM), the robust anticancer drug (CuET) and a near-infrared (NIR) dye (DIR), namely CuET/DIR NPs. A number of in vitro assays were performed including the photothermal efficacy, light-triggered drug release behavior, nuclear localization, DNA damage and induction of apoptosis of CuET/DIR NPs and molecular mechanisms underlying CuET-induced repression on cancer metastatic behaviors. Meanwhile, the mice bearing 4T1-LG12-drived orthotopic tumors were employed to evaluate in vivo biodistribution and anti-tumor effect of CuET/DIR NPs. The intravenous injection model was employed to reflect the changes of the intrinsic metastatic propensity of 4T1-LG12 cells responding to CuET/DIR NPs. Results: The rationally designed nanomedicines have self-traceability for bioimaging, long blood circulation time for enhanced drug accumulation in the tumor site and photo-responsive release of the anticancer drugs. Moreover, our data unearthed that CuET/DIR nanomedicines behave like “Trojan horse” to transport CuET into the cytoplasm, realizing substantial intracellular accumulation. Upon NIR laser irradiation, massive CuET would be triggered to release from the nanomedicines and reach a high local concentration towards the nucleus, where the pro-apoptotic effects were conducted. Importantly, our CuET/DIR nanomedicines revealed a pronounced capability to leash breast cancer metastases through inhibition on EMT. Additionally, these nanomedicines showed great biocompatibility in animals. Conclusion: These combined data unearthed a remarkably enhanced tumor-killing efficacy of our CuET nanomedicines through nuclear targeting. This work may open a new research area of repurposing DSF as innovative therapeutic agents to treat breast cancer and its metastases.

Abstract
Quantitatively delineating the activation network of multiple proteases that participate in cellular processes is highly essential for understanding the physiological and pathological states of cells. In this study, protease-responsive mass barcoded nanotranslators (PRMNTs) were engineered for revealing the activity of cascaded caspases in apoptosis in a multiplex and quantitative manner. In the PRMNTs, a series of mass tag-decorated gold nanoparticles (AuNPs) were tethered onto magnetic Fe3O4 nanospheres via a linker containing the substrate peptide of the target protease to form a "one-to-many" core-satellite structure. This nanostructure was internalized into the cells, underwent an enzymatic reaction within the cells, and allowed post-reaction mass spectrometry (MS) interrogation after magnetic separation from the cells. In the presence of intracellular caspases, enzymatic cleavage of the linker could be translated to the decreased ion signals of the mass tags on the remaining AuNPs in the PRMNTs by MS decoding. Benefiting from the multiplexing capability of MS, the intracellular activity of caspase-3, -8 and -9 that orchestrate the apoptotic process was simultaneously quantified at any given time. Kinetic analysis of caspase activity under stimulation of diverse anticancer drugs revealed that programmed cell death followed individual apoptosis pathways, differing in the activation degree and sequence of the caspase cascade. This work represents a modality that interfaces nanotechnology with MS for quantitatively probing the intracellular activity of multiple proteases, which opens up new avenues for revealing the apoptosis mechanism and developing innovative drugs.

Abstract
Persistent luminescence nanoparticles (PLNPs) are new luminescent materials that can store the excitation energy quickly and persistently emit it after ceasing excitation sources. Due to the advantages of long-lasting luminescence without constant excitation, PLNPs have been widely used in biomedical applications. Visible light excitable PLNPs (VPLNPs) and near-infrared excitable PLNPs (NPLNPs) are two kinds of novel and promising PLNPs. Compared to conventional PLNPs, VPLNPs and NPLNPs have the characteristics of low tissue damage, deep tissue penetration, and high signal-to-noise ratio. With these special features, they have great potential in applications such as long-term tracing, deep-tissue bioimaging, and precise treatment. In this review, we introduce the common strategy of constructing VPLNPs and NPLNPs based on electronic structure engineering and the applications of VPLNPs and NPLNPs in biomedicine. This review article aims to offer valuable information about the progress and development direction of VPLNPs and NPLNPs, promoting more applications in biomedicine, materials science, energy engineering, and environmental technologies in the future.

Abstract
Fully understanding the complicated interplays among various chemical species and organelles is greatly important to unravel the mystery of life. However, fluorescent probes capable of visualizing multiple targets discriminatively are severely deficient, which extremely limit the investigation on intracellular interplays among various species. Towards this end and in consideration of the unique advantages of aggregation-induced emission luminogens (AIEgens), here we rationally designed and presented a single AIEgen, named TVQE, bearing lipophilic, cationic and hydrolyzable moieties, and this AIEgen was capable of illuminating mitochondria and lipid droplets with red and blue emission, respectively. In addition, TVQE was successfully used for evaluating cell viability due to its distinct two-color emission changes tuned by esterase-mediated hydrolysis. Of particular importance is that TVQE can selectively differentiate live, early apoptotic, late apoptotic, and dead cells by confocal microscopy and quantify cell viability statistically by flow cytometry.

Abstract
Ribonuclease H (RNase H), an intracellular ribonuclease, plays a crucial role in cellular processes and especially relates to many disease processes. Here, we report a novel signal amplification strategy based on an RNase H-powered DNA walking machine for specific and sensitive RNase H activity detection. The DNA walking machine is composed of a small quantity of DNA walker strands and abundant FAM-labeled DNA-RNA chimeric strands on a single gold nanoparticle (AuNP). RNase H can specifically degrade the RNA fragment in a DNA-RNA hybrid duplex and trigger the autonomous movement of a DNA walker strand on the AuNP surface. During this process, each step of the walking can release the FAM-labeled RNA from the surface of the AuNP, realizing the signal amplification for RNase H sensing. This method has been successfully utilized for RNase H activity detection in a complex system and applied for screening of related inhibitors. Therefore, our RNase H-powered DNA walking machine gives a novel platform for RNase H activity detection and RNase H-associated drug discovery.

Abstract
Fluorescent nanoprobes based on peptide-functionalized gold nanoparticles (AuNPs) have been widely used in bioassays. The Au-Se bond is considered as a better candidate than the Au-S bond to link the peptides and AuNPs due to the stronger ability against interference of intracellular thiol. However, the current synthetic methods for preparing peptide/AuNPs nanoprobes are always complex and time-consuming. Developing a convenient and rapid method to synthesize the Au-Se bond based nanoprobes is expected to further facilitate their application in fundamental research. Herein, we present a facile and rapid approach to prepare the Au-Se-peptide nanoprobes through a direct freezing process, which is easy-to-operate, time-saving, and surfactant-free. Compared with the traditional method, the amount of peptide loaded on AuNPs by freezing method is also promoted with 20-30%. Furthermore, the obtained nanoprobe was successfully applied to identify autophagy and apoptosis in chemotherapeutic drug treated cancer cells.

Abstract
Monitoring cell viability is a crucial task essential for the fundamental studies in apoptosis, necrosis, and drug discovery. Cell apoptosis and necrosis are significant to maintain the cell population, and their abnormality can lead to severe diseases including cancer. During cell death, significant changes occur in the intracellular contents and physical properties, such as decrease of esterase activity, depolarization of the mitochondrial membrane potential (ΔΨm), increase of caspase content, dissipation of membrane asymmetry, and loss of membrane integrity. To detect cell viability, the fluorescent probes have been developed by taking advantage of these biological parameters and using various fluorescence mechanisms. These fluorescent probes can serve as powerful tools to facilitate the research in biology and pathology. In this Account, the representative examples of the fluorescent probes for cell viability during the past decades have been summarized and classified into five types based on the biological changes. The basic principle, design strategy, fluorescence mechanisms, and molecular construction of these fluorescent probes have been discussed. Furthermore, the intrinsic characteristics and merits of these probes have been illustrated. Particularly, this Account describes our recent works for the design and synthesis of the fluorescent probes to detect cell viability in the dual-color and reversible modes. The dual-color and reversible fluorescent probes are highlighted owing to their unique benefits in accurate and dynamic detection of cell viability. In general, the dual-color fluorescent probes were constructed based on the loss of esterase activity during cell death. Excited-state intramolecular proton transfer (ESIPT) and intramolecular charge transfer (ICT) process were exploited for the probe design. The construction of such dual-color probes were realized by the acetate of the phenyl group on fluorophores. Esterases in healthy cells hydrolyze the acetate and bring a spectral shift to the probes. Moreover, reversible fluorescent probes for cell viability were designed based on the depolarization of ΔΨm, with relocalization properties dependent on ΔΨm. The probes target mitochondria in healthy cells with high ΔΨm, while they are relocalized into the nucleus in unhealthy cells with depolarized ΔΨm. As ΔΨm is reversibly changed according to the cell viability, these probes reversibly detect cell viability. The reversible and simultaneously dual-color fluorescent probes were developed based on the relocalization mode and aggregation-induced emission shift. The probes target mitochondria to form aggregates with deep-red emission, while they migrate into the nucleus to present in monomers with green fluorescence. In this manner, the probes enable dual-color and reversible detection of cell viability. Fluorescent probes for cell viability based on sensing the membrane integrity, caspase activity, and membrane symmetry are also presented. High-polarity and large-size fluorescent probes impermeable to the intact lipid bilayer selectively target apoptotic cells with a destructive plasma membrane. Fluorescent probes sensing caspases in a turn-on manner exclusively light up apoptotic cells with caspase expression. Membrane-impermeable probes with high affinity to phosphatidylserine (PS) specifically stain the plasma membrane of dead cells, since PS flip-flops to the outer leaflet of the membrane during cell death. In summary, this Account illustrates the basic principles, design strategies, characteristics, and advantages of the fluorescent probes for cell viability, and it highlights the dual-color and reversible probes, which can promote the development of fluorescent probes, apoptosis studies, drug discovery, and other relative areas.

Abstract
The accumulation of adenosine in the tumor microenvironment is associated with tumor progression in many cancers. However, whether adenosine is involved in gastric cancer (GC) metastasis and progression, and the underlying molecular mechanism, is largely unclear. In this study, we find that GC tissues and cell lines had higher A2aR levels than nontumor gastric tissues and cell lines. A2aR expression correlated positively with TNMstage, and associated with poor outcomes. Adenosine enhanced the expression of the stemness and epithelial-mesenchymal transition-associated genes by binding to A2aR. A2aR expression on GC cells promoted metastasis in vivo. The PI3K-AKT-mTOR signaling pathway was involved in adenosine-stimulated GC cell migration and invasion. Our results indicate that adenosine promotes GC cell invasion and metastasis by interacting with A2aR to enhance PI3K-AKT-mTOR pathway signaling.

Abstract
Acquiring multilayer information on diverse biomarkers with different spatial distributions at the cellular level is crucial for monitoring the progression of cancers. Herein, a dual-signal-tagged chimeric DNA-functionalized titanium carbide MXenes nanoprobe (dcDNA-Ti3C2) that responds to biomarkers with different cellular locations from plasma membrane to cytoplasm was designed toward this end. In the presence of cancer biomarkers, including transmembrane glycoprotein mucin 1 (MUC1) and cytoplasmic microRNA-21 (miR-21), the recognition between MUC1 and its aptamer in the dcDNA-Ti3C2 probe induces the separation of TAMRA-MUC1 aptamer from Ti3C2 MXenes, thereby resulting in an increase in red fluorescence; and the hybridization of miR-21 with the hairpin probe triggers the increase of green fluorescence. As a result, dual analysis of MUC1 and miR-21 at low-nanomolar concentrations in vitro, as well as in situ simultaneous imaging of the biomarkers within MCF-7 breast cancer cells, was achieved. The feasibility of the nanoprobe was further demonstrated by monitoring the expression changes of both the biomarkers in cancer cells under different inhibitor combinations. Therefore, this strategy allows us to acquire the expression levels and spatial distributions of different biomarkers in living cells, providing a helpful tool for reliable diagnosis of cancers and basic understanding their progression.
