Abstract
Therapeutic nucleic acids hold immense potential in combating undruggable, gene-based diseases owing to their high programmability and relative ease of synthesis. While the delivery of this class of therapeutics has successfully entered the clinical setting, extrahepatic targeting, endosomal escape efficiency, and subcellular localization. On the other hand, viruses serve as natural carriers of nucleic acids and have acquired a plethora of structures and mechanisms that confer remarkable transfection efficiency. Thus, understanding the structure and mechanism of viruses can guide the design of synthetic nucleic acid vectors. This review revisits relevant structural and mechanistic features of viruses as design considerations for efficient nucleic acid delivery systems. This article explores how viral ligand display and a metastable structure are central to the molecular mechanisms of attachment, entry, and viral genome release. For comparison, accounted for are details on the design and intracellular fate of existing nucleic acid carriers and nanostructures that share similar and essential features to viruses. The review, thus, highlights unifying themes of viruses and nucleic acid delivery systems such as genome protection, target specificity, and controlled release. Sophisticated viral mechanisms that are yet to be exploited in oligonucleotide delivery are also identified as they could further the development of next-generation nonviral nucleic acid vectors.

Abstract
During the previous decade, many popular chemical reactions used in the area of "click" chemistry and similarly efficient "click-inspired" reactions have been applied for the design of sequence-defined and, more generally, sequence-controlled structures. This combination of topics has already made quite a significant impact on scientific research to date and has enabled the synthesis of highly functionalized and complex oligomeric and polymeric structures, which offer the prospect of many exciting further developments and applications in the near future. This minireview highlights the fruitful combination of these two topics for the preparation of sequence-controlled oligomeric and macromolecular structures and showcases the vast number of publications in this field within a relatively short span of time. It is divided into three sections according to the click-(inspired) reaction that has been applied: copper-catalyzed azide-alkyne cycloaddition, thiol-X, and related thiolactone-based reactions, and finally Diels-Alder-chemistry-based routes are outlined, respectively.

Abstract
A DNA synthesizer was successfully employed for preparation of well-defined polymers by atom transfer radical polymerization (ATRP), in a technique termed AutoATRP. This method provides well-defined homopolymers, diblock copolymers, and biohybrids under automated photomediated ATRP conditions. PhotoATRP was selected over other ATRP methods because of mild reaction conditions, ambient temperature, tolerance to oxygen, and no need to introduce reducing agents or radical initiators. Both acrylate and methacrylate monomers were successfully polymerized with excellent control in the DNA synthesizer. Diblock copolymers were synthesized with different targeted degrees of polymerization and with high retention of chain-end functionality. Both hydrophobic and hydrophilic monomers were grafted from DNA. The DNA-polymer hybrids were characterized by SEC and DLS. The AutoATRP method provides an efficient route to prepare a range of different polymeric materials, especially polymer-biohybrids.

Self-aggregating 1.8kDa polyethylenimines with dissolution switch at endosomal acidic pH are delivery carriers for plasmid DNA, mRNA, siRNA and exon-skipping oligonucleotides. J Control Release 2016; 246:60-70. [PMID: 27956144 DOI: 10.1016/j.jconrel.2016.12.005] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2016] [Revised: 11/23/2016] [Accepted: 12/05/2016] [Indexed: 11/24/2022]
Abstract
Efficiency of polyethylenimine (PEI) for nucleic acid delivery is affected by the size of the carrier and length of the nucleic acids. For instance, PEIs with molecular weights between 10-30kDa provide optimal DNA delivery activity whereas PEIs with molecular weights below 1.8kDa are ineffective. The activity of PEI is also severely diminished by substitution of DNA for shorter nucleic acids such as mRNA or siRNA. Here, through chemical modification of the primary amines to aromatic domains we achieved nucleic acid delivery by the 1.8kDa polyethylenimine (PEI) particles. This modification did not affect the PEI buffering abilities but enhanced its pH-sensitive aggregation, enabling stabilization of the polyplex outside the cell while still allowing nucleic acid release following cellular entry. The aromatic PEIs were then evaluated for their gene, mRNA, siRNA and 2'O-methyl phosphorothioate oligonucleotide in vitro transfection abilities. The salicylamide-grafted PEI showed to be a reliable carrier for delivering nucleic acids with cytoplasmic activity such as the mRNA and siRNA or nuclear diffusible oligonucleotide. It was then further equipped with polyethyleneglycol (PEG) and the delivery efficiency of the copolymer was tested in vivo for regeneration of dystrophin in the muscle of mdx mouse through a 2'O-methyl phosphorothioate-mediated splicing modulation. Intramuscular administration of polyplexes resulted in dystrophin-positive fibers in a mouse model of Duchenne muscular dystrophy without apparent toxicity. These findings indicate that precise modifications of low molecular weight PEI improve its bio-responsiveness and yield delivery vehicles for nucleic acids of various types in vitro and in vivo.

Abstract
The current interest for platinum N-heterocyclic carbene complexes in cancer research stems from their impressive toxicity reported against a range of different human cancer cells. To date, the demonstration of their in vivo efficacy relative to that of established platinum-based drugs has not been specifically addressed. Here, we introduce an innovative approach to increase the NHC-Pt complex potency whereby multiple NHC-Pt(II) complexes are coordinated along a polyethylenimine polymer (PEI) chain. We show that such NHC-Pt(II)-PEI conjugates induce human cancer cell death in vitro and in vivo in a xenograft mouse model with no observable side effects in contrast to oxaliplatin. Additional studies indicate nucleus and mitochondria targeting and suggest various mechanisms of action compared to classical platinum-based anticancer drugs.

Abstract
Gene delivery to the posterior segment of the eye is severely hindered by the impermeability of defensive barriers; therefore, in clinical settings, genomic medicines are mainly administered by intravitreal injection. We previously found that penetratin could transport the covalently conjugated fluorophore to the fundus oculi by topical instillation. In this study, gene delivery systems enabled by penetratin were designed based on electrostatic binding to target the retina via a noninvasive administration route and prepared with red fluorescent protein plasmid (pRFP) and/or poly(amidoamine) dendrimer of low molecular weight (G3 PAMAM). Formulation optimization, structure confirmation, and characterization were subsequently conducted. Penetratin alone showed limited ability to condense the plasmid but had powerful uptake and transfection by corneal and conjunctival cells. G3 PAMAM was nontoxic to the ocular cells, and when introduced into the penetratin-incorporated complex, the plasmid was condensed more compactly. Therefore, further improved cellular uptake and transfection were observed. After being instilled in the conjunctival sac of rats, the intact complexes penetrated rapidly from the ocular surface into the fundus and resided in the retina for more than 8 h, which resulted in efficient expression of RFP in the posterior segment. Intraocular distribution of the complexes suggested that the plasmids were absorbed into the eyes through a noncorneal pathway during which penetratin played a crucial role. This study provides a facile and friendly approach for intraocular gene delivery and is an important step toward the development of noninvasive gene therapy for posterior segment diseases.

Abstract
Molecular medicine opens into a space of novel specific therapeutic agents: intracellularly active drugs such as peptides, proteins or nucleic acids, which are not able to cross cell membranes and enter the intracellular space on their own. Through the development of cell-targeted shuttles for specific delivery, this restriction in delivery has the potential to be converted into an advantage. On the one hand, due to the multiple extra- and intracellular barriers, such carrier systems need to be multifunctional. On the other hand, they must be precise and reproducibly manufactured due to pharmaceutical reasons. Here we review the design of precise sequence-defined delivery carriers, including solid-phase synthesized peptides and nonpeptidic oligomers, or nucleotide-based carriers such as aptamers and origami nanoboxes.

Abstract
Protease activable antifouling coatings based on peptide-poly(ethylene glycol) conjugates are shown. The material-specific adsorption of a bioconjugate is temporarily suppressed by extending a titanium binding sequence with a proteolytically cleavable epitope and a suitable interfering domain. The adsorption of the PEG-peptide conjugates onto titanium substrates can be regained by cleaving the interfering domain with Tobacco Etch Virus protease. This activates peptide-mediated PEGylation of titanium surfaces and results in coatings that are stable against dilution and suppress nonreversible adsorption of blood protein models. Effects of branched and linear peptidic binding domains on coating stability and antifouling properties are elucidated.

Abstract
Antiviral activity of TiO2 * PL * DNA nanobiocomposites was studied on the MDCK cell culture infected with influenza A virus (subtype H3N2). DNA fragments in the nanocomposites are electrostatically bound to titanium dioxide nanoparticles pre-covered with polylysine. It was shown that TiO2 * PL * DNA(v3') nanocomposite bearing the DNA(v3') fragment targeted to the 3'-end of the noncoding region of segment 5 of viral RNA specifically inhibited the virus reproduction with the efficiency of 99.8 and 99.9% (or by factors of~400 and 1000) at a low concentration of DNA(v3') in nanocomposite (0.1 and 0.2 µM, respectively). The TiO2 * PL * DNA(r) nanocomposite containing oligonucleotide noncomplementary to viral RNA or the oligonucleotide unbound to the nanoparticles show very low antiviral activity (inhibition by factors of~3.5 and 1.3, respectively).

Abstract
In this study, generation 5 (G5) polyamidoamine (PAMAM) dendrimers with two different surface groups, G4.5-COOH and G5-OH, were investigated for their protective effects on pancreas injury in a caerulein-induced acute pancreatitis (AP) mouse model. Both dendrimers significantly decreased pathological changes in the pancreas and reduced the inflammatory infiltration of macrophages in pancreatic tissues. In addition, the expression of pro-inflammatory cytokines was significantly inhibited by the two dendrimers, not only in pancreatic tissues from AP mice but also in vitro in mouse peritoneal macrophages with LPS-induced inflammation. G4.5-COOH, which had better in vivo protective effects for AP than G5-OH, led to a significant reduction in the total number of plasma white blood cells (WBCs) and monocytes in AP mice, and its anti-inflammatory mechanism was related to inhibition of the nuclear translocation of NF-κB in macrophages.

Abstract
Due to low charge density and stiff backbone structure, small interfering RNA (siRNA) has inherently poor binding ability to cationic polymers and lipid carriers, which results in low siRNA loading efficiency and limits siRNA success in clinical application. Here, siRNA-phospholipids conjugates are developed, which integrate the characteristics of the two phospholipids to self-assemble via hydrophilic siRNA and hydrophobic phospholipid tails to overcome the siRNA's stiff backbone structures and enhance the siRNA loading efficiency. In this study, the thiol-modified sense and antisense siRNA are chemically conjugated with phospholipids to form sense and antisense siRNA-phospholipid, and then these sense or antisense siRNA-phospholipids with equal amounts are annealed to generate siRNA-phospholipids. The siRNA-phospholipids can serve dual functions as agents that can silence gene expression and as a component of nanoparticles to embed hydrophobic anticancer drugs to cure tumor. siRNA-phospholipids together with cationic lipids and DSPE-PEG2000 fuse around PLGA to form siRNA-phospholipids enveloped nanoparticles (siRNA-PCNPs), which can deliver siRNAs and hydrophobic anticancer drugs into tumor. In animal models, intravenously injected siRNA-PCNPs embedded DOX (siPlk1-PCNPs/DOX) is highly effective in inhibiting tumor growth. The results indicate that the siRNA-PCNPs can be potentially applied as a safe and efficient gene and anticancer drug delivery carrier.

Abstract
INTRODUCTION The use of aptamers, antisense technology and RNA interference has allowed nucleic acids to be considered as promising alternatives to classical drugs. However, nucleic acids face several obstacles in the creation of effective nucleic acid drugs. The development of these approaches has strengthened the pipeline with an increasing number of these therapies in clinical trials. AREAS COVERED This review covers research and patent literature from the last three years, focusing on the development of safe and effective non-viral drug delivery systems for the treatment of diseases such as cancer or genetic disorders by using oligonucleotides. EXPERT OPINION The therapeutic applications of oligonucleotides have overcome multiple obstacles, especially in biodistribution and cellular internalization. Cationic lipids are the most used vehicles for the preparation of novel formulations. Combinatorial libraries of these compounds and the use of solid lipid nanoparticles carrying these synthetic cationic lipids (cholesterol and PEG) have enhanced cellular uptake and biocompatibility of nucleic acids. Besides this extensive use, synthesis of oligonucleotides covalently linked to lipids has also emerged as a promising alternative to formulations. The use of peptides alone or in combination with lipids is an expanding field for oligonucleotide delivery. Polymeric platforms are also good candidates as they showed improved cellular uptake, biodegradability, biocompatibility and the possibility of incorporating several components, such as ligands for receptor-mediated endocytosis and molecules, to facilitate endosomal escape. Finally, nanomaterials may also play an important role in the future. The last developments showed improvement in in vivo efficacy, thus gaining a foothold in therapeutics.

Abstract
We succeeded in visualizing plasmid DNA (pDNA) in the nucleus and cytosol of non-proliferative cells after transfection with linear polyethylenemine (lPEI) and histidinylated lPEI (His16-lPEI). This was possible with confocal microscope by using pDNA labelled with quantum dots. Indeed pDNA labelled with Cy3 leads to false positive nuclear localization because the saturation of the fluorescence signal overestimated the volume occupied by Cy3-pDNA. Moreover, Cy3 brightness was too weak to detect low amount of pDNA. About 20 to 40 pDNA copies were detected in the nucleus after the transfection of pDNA labelled with quantum dots. Transfection efficiency and cellular imaging data suggested that the cytosolic availability of pDNA, including endosome escape and/or polyplexes dissociation, is crucial for its nuclear delivery. In vitro transcription assay and transfection of cells allowing cytosolic gene expression concluded to better cytosolic availability of pDNA within His16-lPEI polyplexes. Cryo-TEM analyses revealed that His16-lPEI polyplexes exhibited a spherical shape and an amorphous internal structure which differed from the high degree of order of lPEI polyplexes. Altogether, this comparative study indicated that the high transfection efficiency of non-proliferative cells with His16-lPEI polyplexes was related to the amorphous structure and the facilitated dissociation of the assemblies.

Abstract
To address the inherent barriers of gene transfection, two reduction-sensitive branched polypeptides (RBPs) are synthesized and explored as novel non-viral gene vectors. The introduced disulfide linkages in RBPs facilitate glutathione-triggered intracellular gene release and reduce polymer degradation-induced cytotoxicity. Furthermore, the highly branched architecture concurrently realizes multivalency for strong DNA binding and elicits conformational flexibility for tight DNA compacting, which are beneficial for cellular entry. To increase the endosomal escape of plasmid DNA, pH-sensitive histidyl residues are incorporated into RBPs to improve buffer capacity in an acidic environment. In vitro study demonstrates that RBPs can efficiently mediate the DNA transfection and avoid apparent cytotoxicity in HeLa and COS7. The present gene delivery system offers a simple and flexible approach to fabricate microenvironment-specific branched gene vectors for gene therapy.

Abstract
RNA interference (RNAi) was first literaturally reported in 1998 and has become rapidly a promising tool for therapeutic applications in gene therapy. In a typical RNAi process, small interfering RNAs (siRNA) are used to specifically downregulate the expression of the targeted gene, known as the term "gene silencing." One key point for successful gene silencing is to employ a safe and efficient siRNA delivery system. In this context, dendrimers are emerging as potential nonviral vectors to deliver siRNA for RNAi purpose. Dendrimers have attracted intense interest since their emanating research in the 1980s and are extensively studied as efficient DNA delivery vectors in gene transfer applications, due to their unique features based on the well-defined and multivalent structures. Knowing that DNA and RNA possess a similar structure in terms of nucleic acid framework and the electronegative nature, one can also use the excellent DNA delivery properties of dendrimers to develop effective siRNA delivery systems. In this review, the development of dendrimer-based siRNA delivery vectors is summarized, focusing on the vector features (siRNA delivery efficiency, cytotoxicity, etc.) of different types of dendrimers and the related investigations on structure-activity relationship to promote safe and efficient siRNA delivery system.

Abstract
A facile synthetic pathway for preparing block copolymers with pH-responsive L-glutamic acid segments for membrane disruption is reported. Aqueous reversible addition-fragmentation chain transfer (aRAFT) polymerization was first used to prepare biocompatible, nonimmunogenic poly[N-(2-hydroxypropyl)methacrylamide]. This macro chain transfer agent (CTA) was then converted into a macroinitiator via simultaneous aminolysis and thiol-ene Michael addition using the primary amine substituted N-(3-aminopropyl)methacrylamide. This macroinitiator was subsequently utilized in the ring-opening polymerization of the N-carboxyanhydride monomer of γ-benzyl-L-glutamate. After deprotection, the pH-dependent coil-to-helix transformations of the resulting HPMA-b-(L-Glu) copolymers were monitored via circular dichroism spectroscopy. HPMA segments confer water solubility and biocompatibility while the L-glutamic acid repeats provide reversible coil-to-helix transitions at endosomal pH values (~5-6). The endolytic properties of these novel [HPMA-b-(L-Glu)] copolymers and their potential as modular components in drug carrier constructs was demonstrated utilizing red blood cell hemolysis and fluorescein release from POPC vesicles.

Abstract
Glioblastoma multiforme (GBM) is the most common and malignant glioma. Although there has been considerable progress in treatment strategies, the prognosis of many patients with GBM remains poor. In this work, polyethylenimine (PEI) and the VTWTPQAWFQWV (VTW) peptide were modified and synthesized into GBM-targeting nanoparticles. The transfection efficiency of U-87 (human glioblastoma) cells was evaluated using fluorescence microscopy and flow cytometry. Cell internalization was investigated to verify the nanoparticle delivery into the cytoplasm. Results showed that the methods of polymer conjugation and the amount of VTW peptide were important factors to polymer synthesis and transfection. The PEI-VTW20 nanoparticles increased the transfection efficiency significantly. This report describes the use of VTW peptide-based PEI nanoparticles for intracellular gene delivery in a GBM cell-specific manner.

Abstract
mRNA has become an important alternative to DNA as a tool for cell reprogramming. To be expressed, exogenous DNA must be transmitted through the cell cytoplasm and placed into the nucleus. In contrast, exogenous mRNA simply has to be delivered into the cytoplasm. This can result in a highly uniform transfection of the whole population of cells, an advantage that has not been observed with DNA transfer. The use of mRNA, instead of DNA, in medical applications increases protocol safety by abolishing the risk of transgene insertion into host genomes. In this chapter, we review the aspects of mRNA structure and function that are important for its "transgenic" behavior, such as the composition of mRNA molecules and complexes with RNA binding proteins, localization of mRNA in cytoplasmic compartments, translation, and the duration of mRNA expression. In immunotherapy, mRNA is employed in reprogramming of antigen presenting cells (vaccination) and cytolytic lymphocytes. Other applications include generation of induced pluripotent stem (iPS) cells, and genome engineering with modularly assembled nucleases. The most investigated applications of mRNA technology are also reviewed here.

Abstract
Herein, we describe a polymeric micellar nanoparticle capable of rendering nucleic acids resistant to nuclease digestion. This approach relies on utilizing DNA as the polar headgroup of a DNA-polymer amphiphile in order to assemble well-defined, discrete nanoparticles. Dense packing of DNA in the micelle corona allows for hybridization of complementary oligonucleotides while prohibiting enzymatic degradation. We demonstrate the preparation, purification, and characterization of the nanoparticles, then describe their resistance to treatment with endo- and exonucleases including snake-venom phosphodiesterase (SVP), a common, general DNA digestion enzyme.

Abstract
Oral delivery of therapeutic siRNA is an appealing strategy for the treatment of many diseases, however poses numerous challenges to escort siRNA from the site of administration to the cytoplasm of the target cells. Mannose-modified trimethyl chitosan-cysteine (MTC) conjugate nanoparticles (NPs) were developed via ionic gelation and performed as highly effective polymeric vehicles for oral delivery of TNF-α siRNA. The chitosan backbone as well as trimethyl, thiol, and mannose groups of MTC NPs could be activated at proper time and location to overcome the extracellular and intracellular barriers to oral siRNA delivery, thereby promoting gene silencing efficiency. MTC NPs effectively improved siRNA integrity in physiological environment, enhanced siRNA permeation across the intestinal epithelium, facilitated siRNA uptake by macrophages through clathrin-independent endocytosis, and promoted cytoplasmic siRNA release. At equivalent TNF-α siRNA dose, MTC NPs notably outperformed Lipofectamine2000 in terms of in vitro knockdown of TNF-α production in macrophages. Orally delivered MTC NPs containing low amount of TNF-α siRNA (3.75 nm/kg) inhibited TNF-α production in macrophages in vivo, which protected mice with acute hepatic injury from inflammation-induced liver damage and lethality. This study could provide broad insights into the rational design of oral siRNA vehicles for the treatment of inflammatory diseases.

Abstract
The field of RNA nanotechnology is rapidly emerging. RNA can be manipulated with the simplicity characteristic of DNA to produce nanoparticles with a diversity of quaternary structures by self-assembly. Additionally RNA is tremendously versatile in its function and some RNA molecules display catalytic activities much like proteins. Thus, RNA has the advantage of both worlds. However, the instability of RNA has made many scientists flinch away from RNA nanotechnology. Other concerns that have deterred the progress of RNA therapeutics include the induction of interferons, stimulation of cytokines, and activation of other immune systems, as well as short pharmacokinetic profiles in vivo. This review will provide some solutions and perspectives on the chemical and thermodynamic stability, in vivo half-life and biodistribution, yield and production cost, in vivo toxicity and side effect, specific delivery and targeting, as well as endosomal trapping and escape.
