Abstract
As the up-and-comer in the development of RNA nanotechnology, RNA nanomaterials based on functionalized rolling circle transcription (RCT) have become promising carriers for drug production and delivery. This is due to RCT technology can self-produce polyvalent tandem nucleic acid prodrugs for intervention in intracellular gene expression and protein production. RNA component strands participating in de novo assembly enable RCT-based nanomaterials to exhibit good mechanical properties, biostability, and biocompatibility as delivery carriers. The biostability makes it to suitable for thermodynamically/kinetically favorable assembly, enzyme resistance and efficient expression in vivo. Controllable RCT system combined with polymers enables customizable and adjustable size, shape, structure, and stoichiometry of RNA building materials, which provide groundwork for the delivery of advanced drugs. Here, we review the assembly strategies and the dynamic regulation of RCT-based nanomaterials, summarize its functional properties referring to the bottom-up design philosophy, and describe its advancements in tumor gene therapy, synergistic chemotherapy, and immunotherapy. Last, we elaborate on the unique and practical value of RCT-based nanomaterials, namely "self-production and self-sale", and their potential challenges in nanotechnology, material science and biomedicine.

Abstract
RNAs are involved in the crucial processes of disease progression and have emerged as powerful therapeutic targets and diagnostic biomarkers. However, efficient delivery of therapeutic RNA to the targeted location and precise detection of RNA markers remains challenging. Recently, more and more attention has been paid to applying nucleic acid nanoassemblies in diagnosing and treating. Due to the flexibility and deformability of nucleic acids, the nanoassemblies could be fabricated with different shapes and structures. With hybridization, nucleic acid nanoassemblies, including DNA and RNA nanostructures, can be applied to enhance RNA therapeutics and diagnosis. This review briefly introduces the construction and properties of different nucleic acid nanoassemblies and their applications for RNA therapy and diagnosis and makes further prospects for their development.

Abstract
CRISPR-Cas13a holds enormous potential for developing precise RNA editing. However, spatial manipulation of CRISPR-Cas13a activity remains a daunting challenge for elaborately regulating localized RNase function. Here, we designed hierarchical self-uncloaking CRISPR-Cas13a-customized RNA nanococoons (RNCOs-D), featuring tumor-specific recognition and spatial-controlled activation of Cas13a, for precise cancer synergistic therapy. RNCOs-D consists of programmable RNA nanosponges (RNSs) capable of targeted delivery and caging chemotherapeutic drug, and nanocapsules (NCs) anchored on RNSs for cloaking Cas13a/crRNA ribonucleoprotein (Cas13a RNP) activity. The acidic endo/lysosomal microenvironment stimulates the outer decomposition of NCs with concomitant Cas13a RNP activity revitalization, while the inner disassembly through trans-cleavage of RNSs initiated by cis-recognition and cleavage of EGFR variant III (EGFRvIII) mRNA. RNCOs-D demonstrates the effective EGFRvIII mRNA silencing for synergistic therapy of glioblastoma cancer cells in vitro and in vivo. The engineering of RNSs, together with efficient Cas13a activity regulation, holds immense prospect for multimodal and synergistic cancer therapy.

Abstract
Advances in the DNA nanotechnology have enabled the fabrication of DNA-based hydrogels with precisely controlled structures and tunable mechanical and biological properties. Compared to DNA hydrogel, preparation of RNA-based hydrogel remains challenging due to the inherent instability of naked RNA. To overcome these limitations, we fabricated a DNA-RNA hybrid hydrogel via stepwise dual enzymatic polymerization. Multimeric short hairpin RNAs (shRNAs) were hybridized with functional DNA aptamers for targeting and mechanical properties of the hydrogel. The obtained DNA-RNA hybrid hydrogel was ultrasoft, robust, and injectable hence reconfigurable into any confined structures. As a model system, the hydrogel was able to mimic microtubule structures under physiological conditions and designed to release the functional small interfering RNA (siRNA)-aptamer complex (SAC) sequentially. In addition, we encoded restriction enzyme-responsive sites in DNA-RNA hybrid hydrogel to boost the release of SAC. This novel strategy provides an excellent platform for systematic RNA delivery through double-controlled release, SAC release from hydrogel, and subsequent release of siRNA from the SAC, which has promising potential in RNA therapy.

Abstract
Programmable nucleic acids have emerged as powerful building blocks for the bottom-up fabrication of two- or three-dimensional nano- and microsized constructs. Here we describe the construction of organic-inorganic hybrid RNA flowers (hRNFs) via rolling circle transcription (RCT), an enzyme-catalyzed nucleic acid amplification reaction. These hRNFs are highly adaptive structures with controlled sizes, specific nucleic acid sequences, and a highly porous nature. We demonstrated that hRNFs are applicable as potential biological platforms, where the hRNF scaffold can be engineered for versatile surface functionalization and the inorganic component (magnesium ions) can serve as an enzyme cofactor. For surface functionalization, we proposed robust and straightforward approaches including in situ synthesis of functional hRNFs and postfunctionalization of hRNFs that enable facile conjugation with various biomolecules and nanomaterials (i.e., proteins, enzymes, organic dyes, inorganic nanoparticles) using selective chemistries (i.e., avidin-biotin interaction, copper-free click reaction). In particular, we showed that hRNFs can serve as soft scaffolds for β-galactosidase immobilization and greatly enhance enzymatic activity and stability. Therefore, the proposed concepts and methodologies are not only fundamentally interesting when designing RNA scaffolds or RNA bionanomaterials assembled with enzymes but also have significant implications on their future utilization in biomedical applications ranging from enzyme cascades to biosensing and drug delivery.

Abstract
Self-assembled RNA particles have been exploited widely to maximize the therapeutic potential of RNA. However, the immune response via RNA particles is not fully understood. In addition, the investigation of the immunogenicity from RNA-based particles is required owing to inherent immunostimulatory effects of RNA for clinical translation. To examine the immune stimulating potency, rationally designed microsized RNA particles, called RNA microspheres (RMSs), are generated with single or double strands via rolling circle transcription. The RMSs show an exceptional stability in the presence of serum, while they are selectively degraded under endolysosomal conditions. With precisely controlled size, both RMSs are successfully taken up by macrophages. Unlike the nature of RNA fragments, RMSs induce only basal-level expression of inflammatory cytokines as well as type I interferon from macrophages, suggesting that RMSs are immunocompatible in the therapeutic dose range. Taken together, this study could help accelerate clinical translation and broaden the applicability of the self-assembled RNA-based particles without being limited by their potential immunotoxicity, while a systematic controllability study observing the release of RNA fragments from RMSs would provide self-assembled RNA-based structures with a great potential for immunomodulation.

Abstract
Nucleic acid-based technologies have been applied to numerous biomedical applications. As a novel material for target detection, DNA has been used to construct a barcode system with a range of structures. This paper reports multi-functionalized DNA nanospheres (DNANSs) by rolling circle amplification (RCA) with several functionalized nucleotides. DNANSs with a barcode system were designed to exhibit fluorescence for coding enhanced signals and contain biotin for more functionalities, including targeting through the biotin-streptavidin (biotin-STA) interaction. Functionalized deoxynucleotide triphosphates (dNTPs) were mixed in the RCA process and functional moieties can be expressed on the DNANSs. The anti-epidermal growth factor receptor antibodies (anti-EGFR Abs) can be conjugated on DNANSs for targeting cancer cells specifically. As a proof of concept, the potential of the multi-functional DNANS barcode was demonstrated by direct cell detection as a simple detection method. The DNANS barcode provides a new route for the simple and rapid selective recognition of cancer cells.

Abstract
Since the discovery of RNA interference (RNAi), small interfering RNA (siRNA) has been powerful tools for gene downregulation in biomedical applications. Despite the outstanding efficacy of siRNA, the development of a therapeutic delivery system remains a challenge owing to the instability of RNA. In this study, we describe a new method for the design of siRNA-generating nanosponges by using complementary rolling circle transcription (cRCT), a technique that requires two complementary circular DNA. The sequences of one of the circular DNA are designed to have complete complementarity to the target mRNA resulting in double stranded RNA (dsRNA) that can be digested to siRNA by cellular Dicer activity. This siRNA design, called 'library siRNA', could be universally applied to fabricate RNA nanosponges targeting any known mRNA sequence.

Abstract
As ribonucleic acid (RNA) nanotechnology has advanced, it has been applied widely in RNA-based therapeutics. Among the range of approaches, enzymatically synthesized RNA structures for inducing RNA interference in cancer cells have potential for silencing genes in a target-specific manner. On the other hand, the efficiency of gene silencing needs to be improved to utilize the RNA-based system for RNAi therapeutics. This paper introduces a new approach for efficient generation of siRNA from bubbled RNA-based cargo (BRC). The presence of bubbles in between to avoid nonfunctional short dsRNAs allows the RNA-based cargoes to contain multiple Dicer-cleavage sites to release the functional siRNAs when introduced to cells. BRCs can be synthesized easily in a one-pot process and be purified by simple centrifugation. Furthermore, efficient target gene silencing by the bubbled structure is confirmed both in vitro and in vivo. Therefore, this bubbled RNA cargo system can be utilized for target-specific RNAi therapeutics with high efficiency in the generation of functional siRNAs in the target cells.

Pi F, Zhang H, Li H, Thiviyanathan V, Gorenstein DG, Sood AK, Guo P. RNA nanoparticles harboring annexin A2 aptamer can target ovarian cancer for tumor-specific doxorubicin delivery. NANOMEDICINE : NANOTECHNOLOGY, BIOLOGY, AND MEDICINE 2017; 13:1183-1193. [PMID: 27890659 PMCID: PMC5426907 DOI: 10.1016/j.nano.2016.11.015] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2016] [Revised: 11/08/2016] [Accepted: 11/21/2016] [Indexed: 12/21/2022]
Abstract
A novel modified nucleic acid nanoparticle harboring an annexin A2 aptamer for ovarian cancer cell targeting and a GC rich sequence for doxorubicin loading is designed and constructed. The system utilizes a highly stable three-way junction (3WJ) motif from phi29 packaging RNA as a core structure. A phosphorothioate-modified DNA aptamer targeting annexin A2, Endo28, was conjugated to one arm of the 3WJ. The pRNA-3WJ motif retains correct folding of attached aptamer, keeping its functions intact. It is of significant utility for aptamer-mediated targeted delivery. The DNA/RNA hybrid nanoparticles remained intact after systemic injection in mice and strongly bound to tumors with little accumulation in healthy organs 6 h post-injection. The Endo28-3WJ-Sph1/Dox intercalates selectively enhanced toxicity to annexin A2 positive ovarian cancer cells in vitro. The constructed RNA/DNA hybrid nanoparticles can potentially enhance the therapeutic efficiency of doxorubicin at low doses for ovarian cancer treatment through annexin A2 targeted drug delivery.

Abstract
Clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein-9 nuclease (Cas9) can be used for the specific disruption of a target gene to permanently suppress the expression of the protein encoded by the target gene. Efficient delivery of the system to an intracellular target site should be achieved to utilize the tremendous potential of the genome-editing tool in biomedical applications such as the knock-out of disease-related genes and the correction of defect genes. Here, we devise polymeric CRISPR/Cas9 system based on poly-ribonucleoprotein (RNP) nanoparticles consisting of polymeric sgRNA, siRNA, and Cas9 endonuclease in order to improve the delivery efficiency. When delivered by cationic lipids, the RNP nanoparticles built with chimeric poly-sgRNA/siRNA sequences generate multiple sgRNA-Cas9 RNP complexes upon the Dicer-mediated digestion of the siRNA parts, leading to more efficient disruption of the target gene in cells and animal models, compared with the monomeric sgRNA-Cas9 RNP complex.

Abstract
The concept of RNA interference therapeutics has been initiated 18 years ago, and the main bottleneck for translation of the technology into therapeutic products remains the delivery of functional RNA molecules into the cell cytoplasm. In the present review article after an introduction about the theoretical basis of RNAi therapy and the main challenges encountered for its realization, an overview of the different types of delivery systems or carriers, used as potential systems to overcome RNAi delivery issues, will be provided. Characteristic examples or results obtained with the most promising systems will be discussed. Focus will be given mostly on the applications of liposomes or other types of lipid carriers, such as exosomes, towards improved delivery of RNAi to therapeutic targets. Finally the approach of integrating the advantages of these two vesicular systems, liposomes and exosomes, as a potential solution to realize RNAi therapy, will be proposed.

Abstract
For the diagnosis and prevention of diseases, a range of strategies for the detection of pathogens have been developed. In this study, we synthesized the rolling circle amplification (RCA)-based biosensor that enables detection of pathogen DNA in two analytical modes. Only in the presence of the target DNA, the template DNA can be continuously polymerized by simply carrying out RCA, which gives rise to a change of surface structure of Au electrodes and the gap between the electrodes. Electrical signal was generated after introducing hydrogen tetrachloroaurate (HAuCl4) to the DNA-coated biosensor for the improvement of the conductivity of DNA, which indicates that the presence of the pathogen DNA can be detected in an electrical approach. Furthermore, the existence of the target DNA was readily detected by the naked eyes through change in colors of the electrodes from bright yellow to orange-red after RCA reaction. The RCA-based biosensor offers a new platform for monitoring of pathogenic DNA with two different detection modes in one system.
