Abstract
Immunotherapy is a revolutionary and promising approach to cancer treatment. However, traditional cancer immunotherapy often has the disadvantages of limited immune response rate, poor targeting, and low treatment index due to systemic administration. Hydrogels are drug carriers with many advantages. They can be loaded and transported with immunotherapeutic agents, chemical anticancer drugs, radiopharmaceuticals, photothermal agents, photosensitizers, and other therapeutic agents to achieve controlled release of drugs, extend the retention time of drugs, and thus successfully trigger anti-tumor effects and maintain long-term therapeutic effects after administration. This paper reviews recent advances in injectable hydrogel-based cancer immunotherapy, including immunotherapy alone, immunotherapy with combination chemotherapy, radiotherapy, phototherapy, and DNA hydrogel-based immunotherapy. Finally, we review the potential and limitations of injectable hydrogels in cancer immunotherapy.

Zhang H, Wang Z, Liu Y, Xie P. Exploring the direct effects of microcystin-LR on DNA via using cross-technical means. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 241:113841. [PMID: 36068764 DOI: 10.1016/j.ecoenv.2022.113841] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 06/13/2022] [Accepted: 06/30/2022] [Indexed: 06/15/2023]
Abstract
Microcystin-leucine arginine (MC-LR) is the most toxic and abundant microcystin produced by cyanobacteria. Previous studies have demonstrated that MC-LR can lead to DNA damage by increasing intracellular reactive oxygen species content to induce oxidative stress. However, the direct effect of MC-LR on DNA has not been fully described. In this study, the direct effect of MC-LR on DNA was explored by using spectral analysis and molecular biology technology. First, the fluorescent probe Bptp-R2 was developed to monitor different types of DNA and explore the direct interaction between DNA and MC-LR. The significant differences in the fluorescence of probe-plasmid DNA and probe-ds DNA at various MC-LR concentrations (0, 5, 10, 20, and 30 μmol/L) and MC-LR exposure times (0, 6, 12, and 24 h) showed that the direct interaction between DNA and MC-LR was significant (P ≤ 0.01). Gel electrophoresis demonstrated that the direct interaction between DNA and MC-LR cannot cause DNA strand breaks or change DNA configuration. Then, PCR experiments revealed that the direct interaction between DNA and MC-LR cannot affect DNA replication in a PCR system (P ≤ 0.01). This study discovered that the effects of MC-LR on DNA originate mainly from the secondary effects of MC-LR rather than from the direct interaction between DNA and MC-LR.

Abstract
The biological purpose of DNA is to store, replicate, and convey genetic information in cells. Progress in molecular genetics have led to its widespread applications in gene editing, gene therapy, and forensic science. However, in addition to its role as a genetic material, DNA has also emerged as a nongenetic, generic material for diverse biomedical applications. DNA is essentially a natural biopolymer that can be precisely programed by simple chemical modifications to construct materials with desired mechanical, biological, and structural properties. This review critically deciphers the chemical tools and strategies that are currently being employed to harness the nongenetic functions of DNA. Here, the primary product of interest has been crosslinked, hydrated polymers, or hydrogels. State-of-the-art applications of macroscopic, DNA-based hydrogels in the fields of environment, electrochemistry, biologics delivery, and regenerative therapy have been extensively reviewed. Additionally, the review encompasses the status of DNA as a clinically and commercially viable material and provides insight into future possibilities.

Abstract
Guanine-rich oligonucleotide (GRO) can be developed as an effective anticancer agent owing to its high selectivity, affinity and antiproliferative activity in cancer cells. In this study, to increase the potency of GRO29A, a 29-mer GRO aptamer against nucleolin, an overexpressed protein in cancer cells, GRO29A was incorporated into three or six pods of polypod-like structured DNA (polypodna), tripodna or hexapodna, respectively. The polypod-like structured GROs, tri-G3, consisting of one tripodna and three GRO29A, or hexa-G1, hexa-G3 or hexa-G6, each of which comprises one hexapodna and one, three or six GRO29A, respectively, were designed. Tri-G3, hexa-G1 and hexa-G3 were prepared in high yield, except for hexa-G6. Polypod-like structured GROs had quadruplex structures under physiological salt conditions, and degraded at a slower rate in buffer containing serum. Cellular interaction experiments using fluorescently labelled DNA samples showed that the uptake of hexa-G3 by nucleolin-positive MCF-7 cells was more than 2-fold higher than GRO29A, and the interaction was increasingly dependent on the number of GRO29A in the structures. Hexa-G3 inhibited the proliferation of MCF-7 cells in more than 40%, but not of CHO cells. These results indicate that polypod-like structured GROs are useful DNA aptamers with high selectivity and cytotoxicity against nucleolin-positive cancer cells.

Abstract
The discovery of sequence-specific hybridization has allowed the development of DNA nanotechnology, which is divided into two categories: 1) structural DNA nanotechnology, which utilizes DNA as a biopolymer; and 2) dynamic DNA nanotechnology, which focuses on the catalytic reactions or displacement of DNA structures. Recently, numerous attempts have been made to combine DNA nanotechnologies with functional DNAs such as aptamers, DNAzymes, amplified DNA, polymer-conjugated DNA, and DNA loaded on functional nanoparticles for various applications; thus, the new interdisciplinary research field of "functional DNA nanotechnology" is initiated. In particular, a fine-tuned nanostructure composed of functional DNAs has shown immense potential as a programmable nanomachine by controlling DNA dynamics triggered by specific environments. Moreover, the programmability and predictability of functional DNA have enabled the use of DNA nanostructures as nanomedicines for various biomedical applications, such as cargo delivery and molecular drugs via stimuli-mediated dynamic structural changes of functional DNAs. Here, the concepts and recent case studies of functional DNA nanotechnology and nanostructures in nanomedicine are reviewed, and future prospects of functional DNA for nanomedicine are indicated.

Abstract
We have developed a DNA nanoprobe for adenosine triphosphate (ATP) sensing in living cells, based on the split aptamer and the DNA triangular prism (TP). In which nucleic acid aptamer was split into two fragments, the stem of the split aptamer was respectively labeled donor and acceptor fluorophores that underwent a fluorescence resonance energy transfer if two ATP molecules were bound as target molecule to the recognition module. Hence, ATP as a target induced the self-assembly of split aptamer fragments and thereby brought the dual fluorophores into close proximity for high fluorescence resonance energy transfer (FRET) efficiency. In the in vitro assay, an almost 5-fold increase in FA/FD signal was observed, the fluorescence emission ratio was found to be linear with the concentration of ATP in the range of 0.03-2 mM, and the nanoprobe was highly selective toward ATP. For the strong protecting capability to nucleic acids from enzymatic cleavage and the excellent biocompatibility of the TP, the DNA TP nanoprobe exhibited high cellular permeability, fast response, and successfully realized "FRET-off" to "FRET-on" sensing of ATP in living cells. Moreover, the intracellular imaging experiments indicated that the DNA TP nanoprobe could effectively detect ATP and distinguish among changes of ATP levels in living cells. More importantly, using of the split aptamer and the FRET-off to FRET-on sensing mechanism could efficiently avoid false-positive signals. This design provided a strategy to develop biosensors based on the DNA nanostructures for intracellular molecules analysis.

Abstract
The combination of nanostructures with biomolecules leading to the generation of functional nanosystems holds great promise for biotechnological and biomedical applications. As a naturally occurring biomacromolecule, DNA exhibits excellent biocompatibility and programmability. Also, scalable synthesis can be readily realized through automated instruments. Such unique properties, together with Watson-Crick base-pairing interactions, make DNA a particularly promising candidate to be used as a building block material for a wide variety of nanostructures. In the past few decades, various DNA nanostructures have been developed, including one-, two- and three-dimensional nanomaterials. Aptamers are single-stranded DNA or RNA molecules selected by Systematic Evolution of Ligands by Exponential Enrichment (SELEX), with specific recognition abilities to their targets. Therefore, integrating aptamers into DNA nanostructures results in powerful tools for biosensing and bioimaging applications. Furthermore, owing to their high loading capability, aptamer-modified DNA nanostructures have also been altered to play the role of drug nanocarriers for in vivo applications and targeted cancer therapy. In this review, we summarize recent progress in the design of aptamers and related DNA molecule-integrated DNA nanostructures as well as their applications in biosensing, bioimaging and cancer therapy. To begin with, we first introduce the SELEX technology. Subsequently, the methodologies for the preparation of aptamer-integrated DNA nanostructures are presented. Then, we highlight their applications in biosensing and bioimaging for various targets, as well as targeted cancer therapy applications. Finally, we discuss several challenges and further opportunities in this emerging field.

Abstract
Cytosine-phosphate-guanine (CpG) DNA is known to increase the potency of vaccines. Here, in vitro and in vivo stimulation of toll-like receptor 9 by CpG DNA incorporated into polypod-like DNA nanostructures was evaluated by measuring the levels of tumor necrosis factor alpha released from macrophage-like RAW 264.7 cells and plasma interleukin (IL)-12p40 in vivo following intravenous injection into mice. Phosphodiester CpG1668 was selected as the CpG DNA, and tripodna and hexapodna, which were CpG1668-containing tripod and hexapod-like DNA nanostructures, respectively, were designed. CpG-tripodna and CpG-hexapodna induced tumor necrosis factor alpha release from RAW 264.7 cells about 10- and ∼30-fold higher than single-stranded CpG1668 (CpG-SS). Moreover, in all cases examined, plasma IL-12p40 concentrations increased after intravenous injection into mice, with peak levels depending on the samples and the doses. The area under the plasma concentration-time curves indicated that the CpG-hexapodna was approximately 20-fold more efficient in inducing IL-12p40 production than CpG-SS. The efficiency of CpG-tripodna and CpG-hexapodna to increase the potency of CpG-SS in vivo was comparable to that observed in cultured RAW 264.7 cells. These results provide experimental evidence that in vitro studies can be used to estimate the in vivo immunostimulatory activity of CpG DNA incorporated into DNA nanostructures.

Abstract
We present herein a novel combination of gated mesoporous silica nanoparticles (MSNs) and surface-enhanced Raman scattering (SERS) for sensing applications. As a proof-of-concept, we show the design of a system comprising MSNs loaded with crystal violet (CV), a molecule with high Raman cross section acting as SERS reporter, and capped with either a suitable DNA sequence for the detection of Mycoplasma genomic DNA or with an aptamer that selectively coordinates cocaine. In both cases the presence of the corresponding target analyte in solution (i.e., genomic DNA or cocaine) resulted in the release of CV. CV delivery was detected by SERS upon adsorption on gold nanotriangles (AuNTs), which display an efficient electromagnetic field enhancement and a high colloidal stability. By using this novel procedure a limit of detection of at least 30 copies DNA per μL was determined for the detection of Mycoplasma genomic DNA, whereas cocaine was detected at concentrations as low as 10 nm.

Abstract
We explored in detail the relationship between the structure in aqueous solution and immunostimulatory activity of polypod-shaped DNAs, called polypodnas. The polypodnas were constructed using 3-6 oligodeoxynucleotides (ODNs) to obtain tri-, tetra-, penta-, and hexapodna, each of which had 3, 4, 5, and 6 arms made of double-stranded DNA, respectively. A highly potent immunostimulatory CpG sequence was included into each of the polypodnas. Synchrotron X-ray scattering analysis showed that the double-stranded DNA arms of all of the polypodnas adopted a B-form DNA conformation. The analysis also suggested that some nucleotides in the central parts of pentapodna and hexapodna did not form base pairs, whereas those of tripodna and tetrapodna all formed base pairs. This difference would occur because of an increase in steric hindrance and electrical repulsion with increasing number of arms. The pentapodna and hexapodna induced a large amount of tumor necrosis factor α-release from macrophage-like cells compared with the tripodna and tetrapodna, suggesting that the partly loosened DNA in polypodna with many arms is advantageous for exposing the immunostimulatory sequences of the polypodna.

Abstract
We have been investigating the potential use of cell-penetrating peptide-linked polymers as a novel penetration enhancer. Since previous in vivo studies demonstrated that poly(N-vinylacetamide-co-acrylic acid) bearing D-octaarginine, a typical cell-penetrating peptide, enhanced membrane permeation of biomolecules, its potential as an in vitro transfection tool was evaluated in this study. A plasmid DNA encoding green fluorescent protein (pGFP-C1), β-galactosidase, and bovine serum albumin (BSA) were used as model biomolecules. Anionic pGFP-C1 interacted electrostatically with cationic d-octaarginine-linked polymers. When the ratio of mass concentration of polymers to that of pGFP-C1 reached 2.5, complexes whose size and zeta potential were approximately 200 nm and 15 mV, respectively, were obtained. GFP expression was observed in cells incubated with complexes prepared under conditions in which the polymer/pDNA concentration ratio exceeded 2.5. The expression level elevated with an increase in the concentration ratio, but physicochemical properties of the complexes remained unchanged. Results suggested that free polymers contributed to pGFP-C1 internalization. Another cell study demonstrated that β-galactosidase premixed with polymers was taken up into cells in its active tetrameric form. Similar electrostatic interaction-driven complex formation was observed for BSA charged negatively in neutral solution. However, it appeared that the internalization processes of BSA differed from those of pGFP-C1. A mass concentration-dependent increase in internalized BSA was observed, irrespective of the polymer/protein concentration ratio. Due to frail interactions, polymers that were released from the complexes and subsequently immobilized on cell membranes might also contribute to membrane permeation of BSA.

Abstract
Ligand-functionalized, multivalent nanoparticles have been extensively studied as targeted carriers in biomedical applications for drug delivery and imaging. The chemical synthesis method used, however, generates nanoparticles that are heterogeneous with respect to the number of ligands on each nanoparticle. This article examines the role this heterogeneity in ligand number plays in multivalent interactions between nanoparticle ligands and targeted receptors. We designed and synthesized a model heterogeneous multivalent nanoparticle system and developed a unique kinetic analysis to quantify the avidity interactions. This system used mono-dispersed poly(amidoamine) (PAMAM) dendrimers that were then chemically functionalized with ssDNA oligonucleotides as to yield the heterogeneous nanoparticle platform (ligand valencies n = 1.7, 3.1, 6), and employed complementary oligonucleotides as targeted receptors on a surface plasmon resonance (SPR) biosensor to evaluate the multivalent binding of the nanoparticle population. Kinetic analysis of both parallel initial rate and dual-Langmuir analyses of SPR binding curves was performed to assess avidity distributions. We found that batches of multivalent nanoparticles contain both fast- and slow-dissociation subpopulations, which can be characterized as having "weak" and "strong" surface interactions ("binding"), respectively. Furthermore, we found that the proportion of "strong" binders increased as a function of the mean oligonucleotide valence of the nanoparticle population. These analyses allowed an assessment of how avidity distributions are modulated by the number of functionalized ligands and suggested that there are threshold valences that differentiated fast- and slow-dissociation nanoparticles.

Abstract
We demonstrate the generation of systemically releasable anti-cancer drugs from multilayer nanofilms. Nanofilms designed to drug release profiles in programmable fashion are promising new and alternative way for drug delivery. For the nanofilm structure, we synthesized various unique 3-dimensional anti cancer drug incorporated DNA origami structures (hairpin, Y, and X shaped) and assembled with peptide via layer-by-layer (LbL) deposition method. The key to the successful application of these nanofilms requires a novel approach of the influence of DNA architecture for the drug release from functional nano-sized surface. Herein, we have taken first steps in building and controlling the drug incorporated DNA origami based multilayered nanostructure. Our finding highlights the novel and unique drug release character of LbL systems in serum condition taken full advantages of DNA origami structure. This multilayer thin film dramatically affects not only the release profiles but also the structure stability in protein rich serum condition.

Abstract
DNA nanotechnology-based nanosystems and macrosystems have attracted much attention in the biomedical research field. The nature of DNA endows these systems with biodegradable, biocompatible, and immunomodulatory properties. Here, we present an injectable hydrogel system that consists only of chemically synthesized short DNA strands, water, and salts. Several preparations of polypod-like structured DNA, or polypodna, were designed, including tri-, tetra-, penta- and hexapodna, as the building blocks of self-gelling DNA hydrogel. Under physiological conditions, properly designed polypodna preparations formed a hydrogel. The analysis of the modulus data of the hydrogel consisting of two sets of hexapodna preparations showed that this injectable hydrogel was reorganized at a time scale of 0.25s. Then, DNA hydrogel containing unmethylated cytosine-phosphate-guanine (CpG) dinucleotides was used to stimulate innate immunity through Toll-like receptor 9, the receptor for CpG DNA. Gel formation significantly increased the activity of immunostimulatory CpG DNA, retarded the clearance after intradermal injection into mice, and increased the immune responses to ovalbumin (OVA) incorporated into the hydrogel as a model antigen. OVA/CpG DNA hydrogel induced much less local or systemic adverse reactions than OVA injected with complete Freund's adjuvant or alum. GpC DNA hydrogel containing no CpG sequences was less effective, indicating the importance of immunomodulation by CpG DNA hydrogel. Thus, we have created an efficient system for sustained delivery of antigens or other bioactive compounds.

Abstract
The immunostimulatory activity of phosphodiester DNA containing unmethylated cytosine-phosphate-guanine (CpG) dinucleotides, or CpG motifs, was significantly increased by the formation of Y-, X-, or dendrimer-like multibranched shape. These results suggest the possibility that the activity of CpG DNA is a function of the structural properties of branched DNA assemblies. To elucidate the relationship between them, we have designed and developed nanosized DNA assemblies in polypod-like structures (polypod-like structured DNA, or polypodna for short) using oligodeoxynucleotides (ODNs) containing CpG motifs and investigated their structural and immunological properties. Those assemblies consisting of three (tripodna) to eight (octapodna) ODNs were successfully obtained, but one consisting of 12 ODNs was not when 36-mer ODNs were annealed under physiological sodium chloride concentration. High-speed atomic force microscopy revealed that these assemblies were in polypod-like structures. The apparent size of the products was about 10 nm in diameter, and there was an increasing trend with an increase in ODN length or with the pod number. Circular dichroism spectral data showed that DNA in polypodna preparations were in the B-form. The melting temperature of polypodna decreased with increasing pod number. Each polypodna induced the secretion of tumor necrosis factor-α and interleukin-6 from macrophage-like RAW264.7 cells, with the greatest induction by those with hexa- and octapodna. Increasing the pod number increased the uptake by RAW264.7 cells but reduced the stability in serum. These results indicate that CpG DNA-containing polypodna preparations with six or more pods are a promising nanosized device with biodegradability and high immunostimulatory activity.

Abstract
Designed oligonucleotides can self-assemble into DNA nanostructures with well-defined structures and uniform sizes, which provide unprecedented opportunities for biosensing, molecular imaging, and drug delivery. In this work, we have developed functional, multivalent DNA nanostructures by appending unmethylated CpG motifs to three-dimensional DNA tetrahedra. These small-sized functional nanostructures are compact, mechanically stable, and noncytotoxic. We have demonstrated that DNA nanostructures are resistant to nuclease degradation and remain substantially intact in fetal bovine serum and in cells for at least several hours. Significantly, these functional nanostructures can noninvasively and efficiently enter macrophage-like RAW264.7 cells without the aid of transfection agents. After they are uptaken by cells, CpG motifs are recognized by the Toll-like receptor 9 (TLR9) that activates downstream pathways to induce immunostimulatory effects, producing high-level secretion of various pro-inflammatory cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-12. We also show that multivalent CpG motifs greatly enhance the immunostimulatory effect of the nanostructures. Given the high efficacy of these functional nanostructures and their noncytotoxic nature, we expect that DNA nanostructures will become a promising tool for targeted drug delivery.

Abstract
Immunostimulatory CpG DNA was self-assembled to form DNA hydrogels for use as a sustained delivery system for both intercalated doxorubicin (DXR) and immunostimulatory CpG motifs for cancer treatment. X-shaped DNA (X-DNA) was designed as a building unit, and underwent ligation to form DNA hydrogels. Two types of X-DNA were constructed using four oligodeoxynucleotides each, one containing six potent CpG motifs (CpG X-DNA) and the other with none (CpG-free X-DNA). CpG X-DNA was more effective than its components or the CpG-free counterpart in terms of the production of tumor necrosis factor-α from murine macrophage-like RAW264.7 cells, as well as maturation of the murine dendritic DC2.4 cells. The cytotoxic effects of X-DNA, DXR and their complexes were examined in a co-culture system of colon26/Luc cells, a murine adenocarcinoma clone stably expressing firefly luciferase, and RAW264.7 cells. DXR/CpG X-DNA showed the highest ability to inhibit the proliferation of colon26/Luc cells. DXR was slowly released from CpG DNA hydrogels. Injections of DXR/CpG DNA hydrogels into a subcutaneous colon26 tumor effectively inhibited tumor growth. These results show that CpG DNA hydrogels are an effective sustained system for delivery of immunostimulatory signals to TLR9-positive immune cells and DXR to cancer cells.
