Abstract
Smart drug delivery systems (DDSs) that respond to, interact with, or are actuated by biological signals or pathological abnormalities (e.g., the tumor microenvironment) for controllable drug release are appealing therapeutic platforms for cancer treatment. Owing to their inherent self-assembled nature, nucleic acids have emerged as programmable materials for the development of multifunctional structures. In response to external environmental stimuli, DNA response elements can serve as switches to trigger conformational changes in DNA structures. Their stimulus-responsive properties make them promising candidates for constructing smart DDSs, and advancements in DNA response element-based DDSs in the field of biomedicine have been made. This review summarizes different types of DNA response elements, including DNA aptamers, DNAzymes, disulfide bond-modified DNA, pH-responsive DNA motifs, and photocleavable DNA building blocks, and highlights the advancements in DNA response element-based smart DDSs for precise drug release. Finally, future challenges and perspectives in this field are discussed.

Abstract
DNAzymes are DNA oligonucleotides that have catalytic activity without the assistance of protein enzymes. In particular, RNA-cleaving DNAzymes were considered as ideal candidates for gene therapy due to their unique characteristics. Nevertheless, efforts to use DNAzyme as a gene therapeutic agent are limited by issues such as their low physiological stability in serum and intracellular delivery efficiency. In this study, we developed a nanosized synthetic DNA hydrogel functionalized with a DNAzyme tetrahedron (TDz Dgel) to overcome these limitations. We observed remarkable improvement in the gene-silencing effect as well as intracellular uptake without the support of gene transfection reagents using TDz Dgel. The improved catalytic activity of the DNAzyme resulted from the combination of the cell-penetrating DNA tetrahedron structure and high stability of DNA hydrogel. We envision that this approach will become a convenient and efficient strategy for gene-silencing therapy using DNAzyme in the future.

Abstract
Pyroptosis has attracted widespread concerns in cancer therapy, while the therapeutic efficiency could be significantly restricted by using the crucial pyroptosis checkpoint of autophagy and tumor hypoxia. Herein, a DNA nanocomplex (DNFs@ZnMn), containing cascade DNAzymes, promoter-like ZnO2-Mn nanozymes and photosensitizers, was constructed in one pot through rolling circle amplification reactions to induce pyroptosis through disrupting autophagy. After targeting cancer cells with a high expression of H+ and glutathione, DNFs@ZnMn decomposed to expose DNAzymes and promoter-like ZnO2-Mn nanozymes. Then, sufficient metal ions and O2 were released to promote cascade DNA/RNA cleavage and relieving of tumor hypoxia. The released DNAzyme-1 self-cleaved long DNA strands with Zn2+ as the cofactor and simultaneously exposed DNAzyme-2 to cleave ATG-5 mRNA (with Mn2+ as the cofactor). This cascade DNAzyme-mediated gene regulation process induced downregulation of ATG-5 proteins to disrupt autophagy. Simultaneously, the released ZnO2 donated sufficient H2O2 to generate adequate O2 to relieve tumor hypoxia, obtaining highly cytotoxic 1O2 to trigger pyroptosis. By using dynamic cascade gene silencing to disrupt the pyroptosis checkpoint and synergistic relieving of hypoxia, this DNA nanocomplex significantly weakened cellular resistance to achieve efficient pyroptosis therapy both in vitro and in vivo.

Abstract
Emerging research suggests that mitochondrial DNA is a potential target for cancer treatment. However, achieving precise delivery of deoxyribozymes (DNAzymes) and combining photodynamic therapy (PDT) and DNAzyme-based gene silencing together for enhancing mitochondrial gene-photodynamic synergistic therapy remains challenging. Accordingly, herein, intelligent supramolecular nanomicelles are constructed by encapsulating a DNAzyme into a photodynamic O2 economizer for mitochondrial NO gas-enhanced synergistic gene-photodynamic therapy. The designed nanomicelles demonstrate sensitive acid- and red-light sequence-activated behaviors. After entering the cancer cells and targeting the mitochondria, these micelles will disintegrate and release the DNAzyme and Mn (II) porphyrin in the tumor microenvironment. Mn (II) porphyrin acts as a DNAzyme cofactor to activate the DNAzyme for the cleavage reaction. Subsequently, the NO-carrying donor is decomposed under red light irradiation to generate NO that inhibits cellular respiration, facilitating the conversion of more O2 into singlet oxygen (1 O2 ) in the tumor cells, thereby significantly enhancing the efficacy of PDT. In vitro and in vivo experiments reveal that the proposed system can efficiently target mitochondria and exhibits considerable antitumor effects with negligible systemic toxicity. Thus, this study provides a useful conditional platform for the precise delivery of DNAzymes and a novel strategy for activatable NO gas-enhanced mitochondrial gene-photodynamic therapy.

Abstract
Pulmonary metastasis of breast cancer is the major cause of deaths of breast cancer patients, but the effective treatment of pulmonary metastases is still lacking at present. Herein, a degradable biomimetic DNAzyme biocapsule is developed with the poly(ethylenimine) (PEI)-DNAzyme complex encapsulated in a Mn2+/Zn2+-coordinated inositol hexaphosphate (IP6) capsule modified with the cRGD targeting peptide for high-efficiency gene therapy of both primary and pulmonary metastatic breast tumors. This DNAzyme biocapsule is degradable inside acidic lysosomes, leading to the release of DNAzyme and abundant Mn2+/Zn2+ for catalytic cleavage of EGR-1 mRNA. We find that PEI promotes the lysosomal escape of the released DNAzyme. Both in vitro and in vivo experiments demonstrate the apparent downregulation of EGR-1 and Bcl-2 protein expression after treatment with the DNAzyme biocapsule, thereby inducing apoptotic death of tumor cells. We further verify that the DNAzyme biocapsule exhibits potent therapeutic efficacy against both primary and pulmonary metastatic breast tumors with significant inhibition of peri-pulmonary metastasis. This study provides a promising effective strategy for constructing degradable DNAzyme-based platforms with self-supply of abundant metal ion cofactors for high-efficiency gene therapy of metastatic breast cancer.

Abstract
Since their first discovery in 1994, DNAzymes have been extensively applied in biosensing and therapy that act as recognition elements and signal generators with the outstanding properties of good stability, simple synthesis, and high sensitivity. One subset, RNA-cleaving DNAzymes, is widely employed for diverse applications, including as reporters capable of transmitting detectable signals. In this review, the recent advances of RNA-cleaving DNAzyme-based amplification strategies in scaled-up biosensing are focused, the application in diagnosis and disease treatment are also discussed. Two major types of RNA-cleaving DNAzyme-based amplification strategies are highlighted, namely direct response amplification strategies and combinational response amplification strategies. The direct response amplification strategies refer to those based on novel designed single-stranded DNAzyme, and the combinational response amplification strategies mainly include two-part assembled DNAzyme, cascade reactions, CHA/HCR/RCA, DNA walker, CRISPR-Cas12a and aptamer. Finally, the current status of DNAzymes, the challenges, and the prospects of DNAzyme-based biosensors are presented.

Abstract
Liver fibrosis is a progressive histological manifestation that happens in almost all chronic liver diseases. An unabated liver fibrosis may eventually develop into liver cirrhosis or hepatocellular carcinoma. Yet, the strategy for reversal of liver fibrosis is still limited. Herein, a biomimetic nano-regulator (P-ZIF8-cirDNAzyme) is developed to affect both collagen synthesis and degradation in liver to remodel collagen microenvironment. It is found that Zn (II) interference can efficiently inhibit collagen synthesis in activated hepatic stellate cells (aHSC) by inactivating proline 4 hydroxylase and affecting many fibrosis-related signaling pathways. Meanwhile, Zn (II)-dependent circular DNAzymes (cirDNAzymes) are used to efficiently silence tissue inhibitors of metalloproteinase-1, accelerating the degradation of collagen. They act in concert to recover the balance between collagen deposition and degradation. Additionally, ZIF-8-cirDNAzyme is coated by platelet membrane (PM) for precisely targeting aHSC via PM's inflammatory tropism and CD62p-CD44 interaction. In carbon tetrachloride-induced fibrotic mice, P-ZIF-8-cirDNAzyme shows a potent anti-fibrotic effect, greatly reducing the expression of collagen by 73.12% and restoring liver function nearly to normal. This work proposes a prospective platform enabling ion interference and gene silencing, collectively acting in aHSC for reversal of liver fibrosis.

Abstract
DNAzyme-based gene regulation shows great potential for the therapy of many cancers. However, ineffective delivery and insufficient cofactor supply pose challenges for potent gene therapy. In this study, we constructed a smart metal-polyphenol-DNAzyme nanoplatform (TA-Mn@Dz NPs) with intrinsic stability, effective delivery, and cofactor self-supply ability for gene-chemodynamic synergistic tumor therapy. Tannic acid, a plant-derived polyphenol, acts as an intermediate structural unit to mediate the assembly of Mn2+/DNAzyme and tumor acid environment-responsive nanocarriers. Intracellularly, the acidic environment triggers the decomposition of TA-Mn@Dz NPs to release DNAzyme and Mn2+. The Mn2+ ion not only boosts the catalytic cleavage of surviving mRNA for effective gene therapy but also activates chemodynamic therapy (CDT), generating highly toxic ·OH from endogenous H2O2. When tail intravenously injected into MCF-7 tumor-bearing mice, the TA-Mn@Dz NPs display desirable synergistic gene-chemodynamic antitumor effects, paving the way for developing DNAzyme-based multifunctional theranostic platforms for biomedical applications. STATEMENT OF SIGNIFICANCE: 1. A smart metal-polyphenol-DNAzyme nanoplatform was constructed for gene-chemodynamic synergistic tumor therapy. 2. Tannic acid act as intermediate structural units to mediate the assembly of Mn2+/DNAzyme and tumor acid environment-responsive nanocarriers. 3. The Mn2+-ion could not only boost the catalytic cleavage of surviving mRNA for effective gene therapy, but also catalyze endogenous H2O2 to form cytotoxic hydroxyl radicals for chemodynamic therapy. 4. Our work paves an extremely simple way to integrate gene therapy with CDT for the dual-catalytic tumor treatment.

Abstract
Compared with traditional medical methods, gene therapy and photodynamic therapy are the new fields of cancer treatment, and they more accurately and effectively obtain preferable therapeutic effects. In this study, a chemotherapy drug-free nanotherapeutic system based on ZIF-90 encapsulated with Ce6-G3139 and Ce6-DNAzyme for gene and photodynamic therapies was constructed. Once entering the cancer cell, the therapy system will decompose and release Zn2+, Ce6-G3139, and Ce6-DNAzyme in the acidic environment. On the one hand, G3139 binds to the antiapoptotic gene BCL-2 in tumor cells and downregulates related proteins to inhibit tumor proliferation. On the other hand, Zn2+ produced by the decomposition of ZIF-90 can be used as a cofactor to activate the cleavage activity of DNAzyme to initiate gene therapy. Proliferation and metastasis of tumors were further inhibited by DNAzyme, targeting and cutting the gene of human early growth factor-1 (EGR-1). In addition, the photosensitizer Ce6 carried by the nucleic acid will produce cytotoxic ROS to kill cancer cells after irradiation. The results of this study demonstrated that the designed nanoplatform, which synergistically combines gene and photodynamic therapies, has shown great potential for cancer treatment.

[PMID: 36693779 DOI: 10.1002/smll.202206981] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 12/27/2022] [Indexed: 06/17/2023]
Abstract
CRISPR/Cas9-based gene therapy and photodynamic therapy both show promise for cancer treatment but still have their drawbacks limited by tumor microenvironment and long treatment duration. Herein, CRISPR/Cas9 genome editing and photodynamic strategy for a synergistic anti-tumor therapeutic modality is merged. Chlorophyll (Chl) extracted from natural green vegetables is encapsulated in Pluronic F127 (F127) micelles and Histidine-tagged Cas9 can be effectively chelated onto micelles via metal coordination by simple incubation, affording Cas9-Chl@F127 micelles. Mg2+ acts as an enzyme cofactor to correlatively enhance Cas9 gene-editing activity. Upon laser irradiation, Chl as an effective photosensitizer generates reactive oxygen species (ROS) to kill tumor cells. Meanwhile, CRISPR/Cas9, mediated by dual deliberately designed gRNAs of APE1 and NRF2, can reprogram the tumor microenvironment by increasing the intracellular oxygen accumulation and impairing the oxidative defense system of tumor cells. Cas9-Chl@F127 micelles can responsively release Cas9 in the presence of abundant ATP or low pH in tumor cells. In a murine tumor model, Cas9-Chl@F127 complexed with dual gRNAs including APE1 and NRF2 significantly inhibits the tumor growth. Taken together, Cas9-Chl@F127 micelles, representing the first Chl-based green biomaterial for the delivery of Cas9, show great promise for the synergistic anti-tumor treatment by PDT and gene editing.

Abstract
Ribofuranose sugar conformation plays an important role in the structure and dynamics of functional nucleic acids such as siRNAs, AONs, aptamers, miRNAs, etc. To improve their therapeutic potential, several chemical modifications have been introduced into the sugar moiety over the years. The stability of the oligonucleotide duplexes as well as the formation of stable and functional protein-oligonucleotide complexes are dictated by the conformation and dynamics of the sugar moiety. In this review, we systematically categorise various ribofuranose sugar modifications employed in DNAs and RNAs so far. We discuss different stereoelectronic effects imparted by different substituents on the sugar ring and how these effects control sugar puckering. Using this data, it would be possible to predict the precise use of chemical modifications and design novel sugar-modified nucleosides for therapeutic oligonucleotides that can improve their physicochemical properties.

Abstract
Despite the enormous potential of DNAzyme for gene therapy, its efficacy is hampered by the limited endosomal escape capability. Here, we develop a near-infrared (NIR) light-controlled DNAzyme delivery platform to achieve enhanced gene-silencing efficacy. The nanoplatform is composed of therapeutic DNAzyme, photosensitizers (PSs) and upconversion nanoparticles (UCNPs) that can convert NIR light to visible light. The system allows NIR light-activatable generation of cytotoxic reactive oxygen species due to the energy transfer from the UCNPs to PSs, which boosts the endosomal escape of DNAzyme for an improved gene-silencing efficacy. We demonstrate that the nanocomposites represent a promising platform to integrate DNAzyme-based gene therapy with NIR light-triggered photodynamic therapy for combinational tumor treatment. This work highlights a robust approach to combat the current limitations of DNAzyme delivery systems.

Abstract
The 8-17 DNAzyme is the most studied deoxyribozyme in terms of its molecular mechanism; hence it has become a model system to understand the basis behind DNA catalysis. New functional studies and the recent attainment of high-resolution X-ray structures, in addition to theoretical calculations have offered a great opportunity to gain a broader comprehension of its mechanism; however many aspects are unclear yet, especially regarding the precise role of metal ions in catalysis. Recently, molecular dynamics simulations have suggested for the first time a specific and dynamical participation of Na+ in the mechanism through the reaction pathway, besides the roles proposed for divalent metal cofactors. Herein, we present experimental evidence of a cooperative role of the monovalent cation Na+ in catalysis that is in line with these theoretical suggestions. Our findings show a clear influence of the concentration of Na+ on the activity of the 8-17 DNAzyme when Pb2+ is used as the cofactor. Interestingly, this effect is not noticed with Mg2+, indicating a particular contribution of the monovalent ion to catalysis that would operate preferentially with Pb2+. We have also found that Na+ affects the pKa of the general base and the general acid, indicating its influence on general acid-base catalysis, already identified as part of the mechanism of the 8-17 DNAzyme. Finally, our results emphasize the need to consider Na+ carefully in the design and analysis of functional studies of catalytic DNAs and its possible specific role in their mechanisms.

Abstract
Functional nucleic acids(FNAs) refer to a type of oligonucleotides with functions over the traditional genetic roles of nucleic acids, which have been widely applied in screening, sensing and imaging fields. However, the potential application of FNAs in biomedical field is still restricted by the unsatisfactory stability, biocompatibility, biodistribution and immunity of natural nucleic acids(DNA/RNA). Xeno nucleic acids(XNAs) are a kind of nucleic acid analogues with chemically modified sugar groups that possess improved biological properties, including improved biological stability, increased binding affinity, reduced immune responses, and enhanced cell penetration or tissue specificity. In the last two decades, scientists have made great progress in the research of functional xeno nucleic acids, which makes it an emerging attractive biomedical application material. In this review, we summarized the design of functional xeno nucleic acids and their applications in the biomedical field.

Abstract
For many years, numerous efforts have been focused on the development of sensitive, selective, and practical sensors for environmental monitoring, food safety, and medical diagnostic applications. However, the transition from innovative research to commercial success is relatively sparse. In this review, we identify four scientific barriers and one technical barrier to developing successful sensors for practical applications, including the lack of general methods to (a) generate receptors for a wide range of targets, (b) improve sensor selectivity to overcome interferences, (c) transduce the selective binding to different optical, electrochemical, and other signals, and (d) tune dynamic range to match thresholds of detection required for different targets; and the costly development of a new device. We then summarize solutions to overcome these barriers using sensors based on functional nucleic acids that include DNAzymes, aptamers, and aptazymes and how these sensors are coupled to widely available measurement devices to expand their capabilities and lower the barrier for their practical applications in the field and point-of-care settings.

Abstract
Due to the limitations resulting from hypoxia and the self-aggregation of photosensitizers, photodynamic therapy (PDT) has not been applied clinically to treat most types of solid tumors. Zeolitic imidazolate framework-8 (ZIF-8) is a common metal-organic framework that has ultra-high porosity, an adjustable structure, good biocompatibility, and pH-induced biodegradability. In this review, we summarize the applications of ZIF-8 and its derivatives in PDT. This review is divided into two parts. In the first part, we summarize progress in the application of ZIF-8 to enhance PDT and realize theranostics. We discuss the use of ZIF-8 to avoid the self-aggregation of photosensitizers, alleviate hypoxia, increase the PDT penetration depth, and combine PDT with multi-modal imaging. In the second part, we summarize how ZIF-8 can achieve synergistic PDT with other anti-tumor therapies, including chemotherapy, photothermal therapy, chemodynamic therapy, starvation therapy, protein therapy, gene therapy, and immunotherapy. Finally, we highlight the challenges that must be overcome for ZIF-8 to be widely applied in PDT. To the best of our knowledge, this is the first review of ZIF-8-based nanoplatforms for PDT.

Abstract
Photoresponsive nucleic acids attract growing interest as functional constituents in materials science. Integration of photoisomerizable units into DNA strands provides an ideal handle for the reversible reconfiguration of nucleic acid architectures by light irradiation, triggering changes in the chemical and structural properties of the nanostructures that can be exploited in the development of photoresponsive functional devices such as machines, origami structures and ion channels, as well as environmentally adaptable 'smart' materials including nanoparticle aggregates and hydrogels. Moreover, photoresponsive DNA components allow control over the composition of dynamic supramolecular ensembles that mimic native networks. Beyond this, the modification of nucleic acids with photosensitizer functionality enables these biopolymers to act as scaffolds for spatial organization of electron transfer reactions mimicking natural photosynthesis. This review provides a comprehensive overview of these exciting developments in the design of photoresponsive DNA materials, and showcases a range of applications in catalysis, sensing and drug delivery/release. The key challenges facing the development of the field in the coming years are addressed, and exciting emergent research directions are identified.

Abstract
Herein, for the first time, we propose that the cleavage activity of DNAzyme is accompanied by the release of hydroxyl ions, which can be used for colorimetric assay. Subsequently, we further construct a colorimetric strategy for lipopolysaccharide (LPS) analysis by using this property. Detailly, DNAzyme is split into two fragments separately modified with aldehyde group and hydroxylamine group, which can be linked together through oxime chemistry and the presence of LPS can prevent the formation of oxime bond. The formed whole DNAzyme can mediate the release of hydroxyl ions serving for colorimetric signal output. Taking LPS as model targets, DNAzyme-based colorimetric assay has been successfully constructed. This work not only provides a colorimetric strategy to analyze DNAzyme activity, but also gives a new insight to enrich the versatility of DNAzymes and to enhance their multifunctionality.

Abstract
The tool box of site-specific cleavage for nucleic acid has been an increasingly attractive subject. Especially, the recent emergence of the orthogonally activatable DNA device is closely related to the site-specific scission. However, most of these cleavage strategies are based on exogenous assistance, such as laser irradiation. Endogenous strategies are highly desirable for the orthogonally regulatable DNA machine to explore the crucial intracellular biological process and cell signal network. Here, we found that the accurate site-specific cleavage reaction of phosphorothioate (PT) modified DNA by using myeloperoxidase (MPO). A scissors-like mechanism by which MPO breaks PT modification through chloride oxidation has been revealed. Furthermore, we have successfully applied the scissors to activate PT-modified hairpin-DNA machines to produce horseradish peroxidase (HRP)-mimicking DNAzyme or initiate hybridization chain reaction (HCR) amplification. Since MPO plays an important role in the pathway related to oxidative stress in cells, through the HCR amplification activated by this tool box, the oxidative stress in living cells has been robustly imaged. This work proposes an accurate and endogenous site-specific cleavage tool for the research of biostimuli and the construction of DNA molecular devices.

Abstract
A click chemistry assay based on a newly discovered DNAzyme, CLICK-17, with azide modified gold nanoparticles (azide-AuNPs) and alkyne capped dsDNA (alkyne-linker DNA) was employed for novel and selective detection of Cu2+ visually. The strategy involved using CLICK-17 to mediate a catalytic reaction for triazole formation between azide-AuNPs and alkyne-linker DNA under the help of Cu2+ (without sodium ascorbate) or Cu+, which eventually led to the aggregation of AuNPs. The obvious color change from ruby red to bluish purple was then observed by the naked eye and the absorbance peak shifted from 525 to 570 nm. Interestingly, CLICK-17 and Cu+-catalyzed click reaction had the best performance compared to either Cu+ alone or CLICK-17 and Cu2+-mediated reaction in terms of the reaction time and sensitivity. This system has been demonstrated to allow quantitative measurement of Cu2+ with a detection limit as low as 26.8 nM and also has high specificity that can distinguish Cu2+ from other metal ions. Further, the method was tested with a real mineral water sample for Cu2+ concentration determination. Satisfactory recoveries of 90.8% and 99.8% were achieved. We report selective and visual detection of Cu2+ based on aggregation of azide modified gold nanoparticles induced by CLICK-17 DNAzyme and Cu2+ or Cu+ catalyzed click reaction between azide-AuNPs and alkyne-dsDNA.![]()

Abstract
The RNA-cleaving 8-17 DNAzyme, which is a metalloenzyme that depends on divalent metal ions for its function, is the most studied catalytic DNA in terms of its mechanism. By the end of 2017, a report of the crystal structure of the enzyme-substrate complex in the presence of Pb2+ probed some of the previous findings and opened new questions, especially around the participation of the metal ion in the catalytic mechanism and the promiscuity exhibited by the enzyme in terms of the metal cofactor required for catalysis. In this article we explore the role of the divalent metal ion in the mechanism of the 8-17 DNAzyme as a general acid, by measuring the influence of pH over the activity of a slower variant of the enzyme in the presence of Pb2+. We replaced G14, which has been identified as a general base in the mechanism of the enzyme, by the unnatural analog 2-aminopurine, with a lower pKa value of the N1 group. With this approach, we obtained a bell-shaped pH-rate profile with experimental pKa values of 5.4 and 7.0. Comparing these results with previous pH-rate profiles in the presence of Mg2+, our findings suggest the stabilization of the 5'-O leaving group by the hydrated metal ion acting as a general acid, in addition to the activation of the 2'-OH nucleophile by the general base G14.

Abstract
Despite the great efforts of using DNAzyme for gene therapy, its clinical success is limited by the lack of simple delivery systems and limited anticancer efficacy. Here, we develop a simple approach for the synthesis of hybrid nanostructures that exclusively consist of DNAzyme and Cu2+ with ultra-high loading capacity. The Cu-DNAzyme nanohybrids allow to effectively co-deliver DNAzyme and Cu2+ into cancer cells for combinational catalytic therapy. The released Cu2+ can be reduced to Cu+ by glutathione and then catalyze endogenous H2 O2 to form cytotoxic hydroxyl radicals for chemodynamic therapy (CDT), while the 10-23 DNAzyme enables the catalytic cleavage of VEGFR2 mRNA and activates gene silencing for gene therapy. We demonstrate that the system can efficiently accumulate in the tumor and exhibit amplified cascade antitumor effects with negligible systemic toxicity. Our work paves an extremely simple way to integrate DNAzyme with CDT for the dual-catalytic tumor treatment.

Abstract
Stimuli-responsive metal-organic framework nanoparticles, NMOFs, provide a versatile platform for the controlled release of drugs and biomedical applications. The porous structure of NMOFs, their biocompatibility, low toxicity, and efficient permeability turn the NMOFs into ideal carriers for therapeutic applications. Two general methods to gate the drug-loaded NMOFs and to release the loads were developed: by one method, the loaded NMOFs are coated or surface-modified with stimuli-responsive gates being unlocked in the presence of appropriate chemical (e.g., ions or reducing agents), physical (e.g., light or heat), or biomarker (e.g., miRNA or ATP) triggers. By a second approach, the drug-loaded NMOFs include encoded structural information or co-added agents to induce the structural distortion or stimulate the degradation of the NMOFs. Different chemical triggers such as pH changes, ions, ATP, or redox agents, and physical stimuli such as light or heat are applied to degrade the NMOFs, resulting in the release of the loads. In addition, enzymes, DNAzymes, and disease-specific biomarkers are used to unlock the gated NMOFs. The triggered release of drugs for cancer therapy, anti-blood clotting, and the design of autonomous insulin-delivery systems ("artificial pancreas") are discussed. Specifically, multi-drug carrier systems and functional NMOFs exhibiting dual and cooperative therapeutic functions are introduced. The future perspectives and applications of stimuli-responsive particles are addressed.

Abstract
Herein, we developed hybrid DNAzyme nanoparticles (NPs) to achieve light-induced carrier-free self-delivery of DNAzymes with sufficient cofactor supply and lysosome escape capacity. In this system, aggregation-induced emission (AIE) photosensitizer (PS) (TBD-Br) was grafted onto a phosphorothiolated DNAzyme backbone, which automatically self-assembled to form NPs and the surface phosphorothioate group could easily coordinate with the cofactor Zn2+ in the buffer. When the yielded hybrid DNAzyme NPs were located inside tumor cell lysosomes, the 1O2 from TBD-Br under light illumination could destroy lysosome structure and promote the Zn2+ coordinated DNAzyme NPs escape. Both in vitro and in vivo results demonstrated that the hybrid DNAzyme NPs could downregulate the early growth response factor-1 protein (EGR-1) to inhibit tumor cell growth in addition to induce tumor cell apoptosis by AIE PS (TBD-Br) under light irradiation.

Abstract
The combination of gene therapy with chemotherapeutics provides an efficacious strategy for enhanced tumor therapy. RNA-cleaving DNAzyme has been recognized as a promising gene-silencing tool, while its combination with chemotherapeutic drugs has been limited by the lack of an effective codelivery system to allow sufficient intracellular DNAzyme activation, which requires specific metal ions as a cofactor. Here, a self-activatable DNAzyme/drug core-shell codelivery system is fabricated to combat triple-negative breast cancer (TNBC). The hydrophobic chemotherapeutic, rapamycin (RAP), is self-assembled into the pure drug nanocore, and the metal-organic framework (MOF) shell based on coordination between Mn2+ and tannic acid (TA) is coated on the surface to coload an autophagy-inhibiting DNAzyme. The nanosystem efficiently delivers the payloads into tumor cells, and upon endocytosis, the MOF shell is disintegrated to release the therapeutics in response to an acidic endo/lysosome environment and intracellular glutathione (GSH). Notably, the coreleased Mn2+ serves as the cofactor of DNAzyme for effective self-activation, which suppresses the expression of Beclin 1 protein, the key initiator of autophagy, resulting in a significantly strengthened antitumor effect of RAP. Using tumor-bearing mouse models, the nanosystem could passively accumulate into the tumor tissue, impose potent gene-silencing efficacy, and thus sensitize chemotherapy to inhibit tumor growth upon intravenous administration, providing opportunities for combined gene-drug TNBC therapy.

Abstract
Since 1994, deoxyribozymes or DNAzymes have been in vitro selected to catalyze various types of reactions. Metal ions play a critical role in DNAzyme catalysis, and Zn2+ is a very important one among them. Zn2+ has good biocompatibility and can be used for intracellular applications. Chemically, Zn2+ is a Lewis acid and it can bind to both the phosphate backbone and the nucleobases of DNA. Zn2+ undergoes hydrolysis even at neutral pH, and the partially hydrolyzed polynuclear complexes can affect the interactions with DNA. These features have made Zn2+ a unique cofactor for DNAzyme reactions. This review summarizes Zn2+ -dependent DNAzymes with an emphasis on RNA-/DNA-cleaving reactions. A key feature is the sharp Zn2+ concentration and pH-dependent activity for many of the DNAzymes. The applications of these DNAzymes as biosensors for Zn2+ , as therapeutic agents to cleave intracellular RNA, and as chemical biology tools to manipulate DNA are discussed. Future studies can focus on the selection of new DNAzymes with improved performance and detailed biochemical characterizations to understand the role of Zn2+ , which can facilitate practical applications of Zn2+ -dependent DNAzymes.

Abstract
DNAzymes are in vitro selected DNA oligonucleotides with catalytic activities. RNA cleavage is one of the most extensively studied DNAzyme reactions. To expand the chemical functionality of DNA, various chemical modifications have been made during and after selection. In this review, we summarize examples of RNA-cleaving DNAzymes and focus on those modifications introduced during in vitro selection. By incorporating various modified nucleotides via polymerase chain reaction (PCR) or primer extension, a few DNAzymes were obtained that can be specifically activated by metal ions such as Zn2+ and Hg2+. In addition, some modifications were introduced to mimic RNase A that can cleave RNA substrates in the absence of divalent metal ions. In addition, single modifications at the fixed regions of DNA libraries, especially at the cleavage junctions, have been tested, and examples of DNAzymes with phosphorothioate and histidine-glycine modified tertiary amine were successfully obtained specific for Cu2+, Cd2+, Zn2+, and Ni2+. Labeling fluorophore/quencher pair right next to the cleavage junction was also used to obtain signaling DNAzymes for detecting various metal ions and cells. Furthermore, we reviewed work on the cleavage of 2'-5' linked RNA and L-RNA substrates. Finally, applications of these modified DNAzymes as biosensors, RNases, and biochemical probes are briefly described with a few future research opportunities outlined at the end.

Abstract
DNAzymes exhibit high potential as gene silencing agents for therapeutic applications. Such purposes, however, are significantly challenged by the targeted and successful delivery of unmodified DNAzymes into cells with minimal side effects. Here, we set out to formulate and demonstrate a new stimuli-responsive and constrained aptamer/DNAzyme (Apt/Dz) catenane nanostructure for highly specific gene silencing. The rational design of the Apt/Dz catenane nanostructure with the respective integration of the aptamer sequence and the completely closed catenane format enables both the targeted capability and significantly improved nuclease resistance, facilitating the stable and targeted delivery of unmodified Dz into cancer cells. Moreover, the Dz enzymatic activity in the constrained structure can only be conditionally regulated by the specific intracellular mRNA sequences to silence the target gene with highly reduced side effects. Results show that the Apt/Dz catenane nanostructure can effectively inhibit the expression of the target gene and the proliferation of cancer cells with high specificity.

Acta Biomater 2020; 110:242-253. [PMID: 32438113 DOI: 10.1016/j.actbio.2020.04.041] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 04/23/2020] [Accepted: 04/23/2020] [Indexed: 12/16/2022]
Abstract
Multi-modal nanomedicines that synergistically combine chemo-, gene-, and photothermal therapy have shown great potential for cancer treatment. In this study, a core-shell nanosystem-based on a zinc oxide (ZnO) nanocore and a polydopamine (PDA) shell was constructed to integrate chemo- (doxorubicin, DOX), gene- (DNAzyme, DZ), and photothermal (PDA layer) therapy in one system. Instead of small interfering RNAs, we employed DZ for tumor-related gene (survivin) regulation owing to its higher stability, biocompatibility, and predictable activity. DOX and amino-modified DZ were loaded onto the PDA shell via physisorption and covalent conjugation, respectively. Specifically, the ZnO nanocore was designed as a metal cofactor reservoir to release Zn2+ in response to intracellular stimuli, which triggered the activation of DZ for gene silencing after endocytosis into cells. Both in vitro and in vivo experiments demonstrated the enhanced anti-tumor efficacy of these multifunctional nanocomposites and highlighted the advantages of these nano-drug delivery systems to alleviate the side effects of DOX. This study provides a strategy for synergistic cancer therapy via chemo/gene/photothermal combination and offers a strategy to harness DZ as a gene-silencing tool for disease treatment in combination with other therapeutic modalities. STATEMENT OF SIGNIFICANCE: In this work, we constructed a core-shell nanosystem containing a zinc oxide (ZnO) nanocore and a polydopamine (PDA) outer layer, which integrated chemo- (doxorubicin, DOX), gene- (DNAzyme, DZ), and photothermal (PDA layer) therapies for multimodal cancer therapy. Specifically, the ZnO core was incorporated to solve the key issue of DZ for gene silencing applications, which acted as the metal cofactor reservoir to release Zn2+ inside cells for effective DZ activation. In addition, the PDA shell could detoxify the ZnO by scavenging the reactive oxygen species produced by ZnO, thus increasing the biocompatibility of the nanocarrier. This work solves the key issue of DZ for RNAi-based applications, offers a platform to combine DZ with other therapeutic modalities, and also provides a smart strategy to achieve triggered activation of biocatalytic reactions for therapeutic applications.

Abstract
Temozolomide (TMZ), the most common DNA alkylating agent, is predominantly mediated by O6-methylguanine DNA lesions for the treatment of glioblastoma (GBM). When O6-methylguanine-DNA methyltransferase (MGMT) is present, TMZ-induced O6-methylguanine lesions are repaired, resulting in the emergence of resistance to chemotherapy. Herein, we attempted to enhance the response of T98G cells to TMZ by gene silencing of MGMT. In this work, we developed transition metal manganese (Mn)-doped mesoporous silica nanoparticles (MSNs) as a carrier system for the co-delivery of TMZ and 10-23 DNAzyme, and realized gene silencing to enhance the TMZ sensitivity in T98G cells. The intelligent theranostic platform based on manganese-doped mesoporous silica nanoparticles (Mn-MSNs) can be decomposed and release chemotherapy drugs under acidic pH and reducing conditions. Meanwhile, the produced Mn2+ could act as a cofactor of 10-23 DNAzyme to effectively cleave MGMT mRNA, knock down MGMT protein, and sensitize T98G cells to TMZ-induced apoptosis. By co-delivering TMZ and 10-23 DNAzyme employing Mn-MSNs, the concentrations of TMZ that needed to inhibit cell growth by 50% (IC50 values) decreased (by more than 3.8-fold) compared with free TMZ. This work shows that the designed platform holds great promise for advancing the treatment of drug-resistant cancer.

Abstract
We herein report a DNAzyme named T30695 (sequence: (G3 T)4 ) that can catalyze Zn2+ insertion into three different porphyrins in the presence of Pb2+ as a cofactor. Meanwhile, T30695 with Pb2+ alone was found to cause a shift in both the fluorescence and UV-vis spectra of protoporphyrin IX (PPIX), thus suggesting that metalation of Pb2+ was also achieved at room temperature. From kinetic measurements, the reaction required two Pb2+ ions; this is consistent with one being a cofactor and the other being a substrate. No previous reports inserted Pb2+ into porphyrins by using DNAzymes or protein-based enzymes. This reaction was most significantly inhibited in the presence of K+ followed by Na+ and Li+ , suggesting the importance of the Pb2+ -stabilized G-quadruplex. When Pb2+ is inserted into PPIX, its emission blue shifts from 635 to 590 nm, thus allowing simple ratiometric fluorescent sensing with a detection limit of 1.2 nM Pb2+ .

Abstract
Since the initial discovery of ribozymes in the early 1980s, catalytic nucleic acids have been used in different areas. Compared with protein enzymes, catalytic nucleic acids are programmable in structure, easy to modify, and more stable especially for DNA. We take a historic view to summarize a few main interdisciplinary areas of research on nucleic acid enzymes that may have broader impacts. Early efforts on ribozymes in the 1980s have broken the notion that all enzymes are proteins, supplying new evidence for the RNA world hypothesis. In 1994, the first catalytic DNA (DNAzyme) was reported. Since 2000, the biosensor applications of DNAzymes have emerged and DNAzymes are particularly useful for detecting metal ions, a challenging task for enzymes and antibodies. Combined with nanotechnology, DNAzymes are key building elements for switches allowing dynamic control of materials assembly. The search for new DNAzymes and ribozymes is facilitated by developments in DNA sequencing and computational algorithms, further broadening our fundamental understanding of their biochemistry.

Abstract
Rheumatoid arthritis (RA) is a systemic inflammatory joint disease affecting about 1% of the population worldwide. Current treatment approaches do not ensure a cure for every patient. Moreover, classical regimens are based on nontargeted systemic immune suppression and have significant side effects. Biological treatment has advanced considerably but efficacy and specificity issues remain. Gene therapy is one of the potential future directions for RA therapy, which is rapidly developing. Several gene therapy trials done so far have been of moderate success, but experimental and genetics studies have yielded novel targets. As a result, the arsenal of gene therapy tools keeps growing. Currently, both viral and nonviral delivery systems are used for RA therapy. Herein, we review recent approaches for RA gene therapy.

Abstract
DNA functionalized nanomaterials have attracted tremendous attention for bioanalytical applications. Owing to exceptional fluorescence quenching ability, most DNA-based nanoprobes were designed with turn-on signals for target gene detection, while only a few of them could simultaneously achieve gene detection and regulation in one system. In this study, we explored the use of nanoscale zeolitic imidazolate framework-8 (ZIF-8) as a building block to construct a DNA-based nanoprobe. We found ZIF-8 could stably adsorb DNA to resist the dissociation by various biological ligands, enabling potential biological applications. However, ZIF-8 was not a nano-quencher to turn off the fluorophore labeling on the adsorbed DNA. We therefore designed a DNAzyme embedded molecular beacon (DMB) to functionalize ZIF-8. After endocytosis, ZIF-8 was disintegrated to release DMB for target mRNA detection, and the co-released Zn2+ acted as an effective cofactor to activate the embedded DNAzyme for mRNA regulation. This study provides a versatile nano-platform to realize multiple functions inside cells by using functional nucleic acids, which holds great promise for theranostic applications.

Abstract
Metal ions can be beneficial or toxic depending on their identity, oxidation state, and concentration. Therefore, the ability to detect and quantify different types of metal ions using portable sensors or in situ imaging agents is important for better environmental monitoring, in vitro medical diagnostics, and imaging of biological systems. While numerous metal ions in different oxidation states are present in the environment and biological systems, only a limited number of them can be detected effectively using current methods. In this Account, we summarize research results from our group that overcome this limitation by the development of a novel class of activity-based sensors based on metal-dependent DNAzymes, which are DNA molecules with enzymatic activity. First, we have developed an in vitro selection method to obtain DNAzymes from a large DNA library of up to 1015 sequences that can carry out cleavage of an oligonucleotide substrate only in the presence of a specific metal ion with high selectivity. Negative selection steps can further be used to improve the selectivity against potentially competing targets by removing sequences that recognize the competing metal ions. Second, we have developed a patented catalytic beacon method to transform the metal-dependent DNAzyme cleavage reaction into a turn-on fluorescent signal by attaching a fluorophore and quenchers to the DNAzyme complex. Because of the difference in the melting temperatures of DNA hybridization before and after metal-ion-dependent cleavage of the DNAzyme substrate, the fluorophore on the DNA cleavage product can be released from its quenchers to create a turn-on fluorescent signal. Because DNAzymes are easy to conjugate with other signaling moieties, such as gold nanoparticles, lanthanide-doped upconversion nanoparticles, electrochemical agents, and gadolinium complexes, these DNAzymes can also readily be converted into colorimetric sensors, upconversion luminescence sensors, electrochemical sensors, or magnetic resonance contrast agents. In addition to describing recent progress in developing and applying these metal ion sensors for environmental monitoring, point-of-care diagnostics, cellular imaging, and in vivo imaging in zebrafish, we summarize major advantages of this class of activity-based sensors. In addition to advantages common to most activity-based sensors, such as enzymatic turnovers that allow for signal amplification and the use of initial rates instead of absolute signals for quantification to avoid interferences from sample matrices, the DNAzyme-based sensors allow for in vitro selection to expand the method to almost any metal ion under a variety of conditions, negative selection to improve the selectivity against competing targets, and reselection of DNAzymes and combination of active and inactive variants to fine-tune the dynamic range of detection. The use of melting temperature differences to separate target binding from signaling moieties in the catalytic beacon method allows the use of different fluorophores and nanomaterials to extend the versatility and modularity of this sensing platform. Furthermore, sensing and imaging artifacts can be minimized by using an inactive mutant DNAzyme as a negative control, while spatiotemporal control of sensing/imaging can be achieved using optical, photothermal, and endogenous orthogonal caging methods. Finally, current challenges, opportunities, and future perspectives for DNAzymes as activity-based sensors are also discussed.
