Abstract
Based on the fluorescence resonance energy transfer (FRET) and fluorescence anisotropy (FA), the present study reported proof-of-principle for a highly sensitive and rapid detection technique that can be precisely utilized for investigating the self-assembly of polydeoxyadenylic acid (poly(dA)) and β-glucan, and the interactions of the poly(dA)-β-glucan complex on the surface of graphene oxide (GO). Due to the noncovalent assembly of fluorescein amidite (FAM)-labeled poly(dA) and GO via π-π stacking, the fluorescence of (FAM)-labeled poly(dA) as a molecular aptamer beacon (MAB) was completely quenched by GO. Conversely, the addition of single-stranded lentinan (s-LNT) resulted in the significant restoration of fluorescence due to the formation of poly(dA)-s-LNT complexes with a stiff rod-like structure, which had a weak affinity to GO and kept the dyes away from GO. However, relatively weak fluorescence restoration was observed by adding another single-stranded curdlan (s-CUR) for positive control, indicative of complex formation with higher binding ability to GO. The fluorescence anisotropy (FA) was also combined to confirm the occurrence with different increments of anisotropy relative to the free poly(dA), which could be conveniently extended for detecting the assembly of other biomolecules with higher sensitivity.

Abstract
This work investigates the impact of quality attributes (impurity content, plasmid charge, and compactness) of plasmid DNA isolated with different purification methodologies on the characteristics of lipoplexes prepared thereof (size, zeta potential, stability) and on their ability to transfect mammalian cells. A 3.7 kb plasmid with a green fluorescence protein (GFP) reporter gene, Lipofectamine®-based liposomes, and Chinese Hamster Ovary (CHO) cells were used as models. The plasmid was purified by hydrophobic interaction chromatography (HIC)/gel filtration, and with three commercial kits, which combine the use of chaotropic salts with silica membranes/glass fiber fleeces. The HIC-based protocol delivered a plasmid with the smallest hydrodynamic diameter (144 nm) and zeta potential (-46.5 mV), which is virtually free from impurities. When formulated with Lipofectamine®, this plasmid originated the smallest (146 nm), most charged (+13 mV), and most stable lipoplexes. In vitro transfection experiments further showed that these lipoplexes performed better in terms of plasmid uptake (∼500,000 vs. ∼100,000-200,000 copy number/cell), transfection efficiency (50% vs. 20%-40%), and GFP expression levels (twofold higher) when compared with lipoplexes prepared with plasmids isolated using commercial kits. Overall our observations highlight the potential impact that plasmid purification methodologies can have on the outcome of gene transfer experiments and trials.

Abstract
We report on the technical advance of linearized pDNA (pDNA(linear)) above the circular one (pDNA(circ)) for preparation of small-sized DNA/polycation complexes (DPC) at a low pH. Also, the resistance of the DPC formed with pDNA(linear) against poly-L-asparagine indicates that effective ion-pairing occurred between the pDNA(linear) and polycations.

Abstract
Carbohydrates have been investigated and developed as delivery vehicles for shuttling nucleic acids into cells. In this review, we present the state of the art in carbohydrate-based polymeric vehicles for nucleic acid delivery, with the focus on the recent successes in preclinical models, both in vitro and in vivo. Polymeric scaffolds based on the natural polysaccharides chitosan, hyaluronan, pullulan, dextran, and schizophyllan each have unique properties and potential for modification, and these results are discussed with the focus on facile synthetic routes and favorable performance in biological systems. Many of these carbohydrates have been used to develop alternative types of biomaterials for nucleic acid delivery to typical polyplexes, and these novel materials are discussed. Also presented are polymeric vehicles that incorporate copolymerized carbohydrates into polymer backbones based on polyethylenimine and polylysine and their effect on transfection and biocompatibility. Unique scaffolds, such as clusters and polymers based on cyclodextrin (CD), are also discussed, with the focus on recent successes in vivo and in the clinic. These results are presented with the emphasis on the role of carbohydrate and charge on transfection. Use of carbohydrates as molecular recognition ligands for cell-type specific delivery is also briefly reviewed. We contend that carbohydrates have contributed significantly to progress in the field of non-viral DNA delivery, and these new discoveries are impactful for developing new vehicles and materials for treatment of human disease.

Abstract
Nonviral gene delivery technologies have been developed using layer-by-layer self-assembly of nanomaterials held together by electrostatic interactions in order to provide nanoparticulate materials that protect and deliver DNA to cells. Here we report a new DNA delivery technology based on the in situ layer-by-layer synthesis of DNA nanoparticles caged within hollow yeast cell wall particles (YCWP). YCWP provide protection and facilitate oral and systemic receptor-targeted delivery of DNA payloads to phagocytic cells. The nanoparticles inside YCWP consist of a core of tRNA/polyethylenimine (PEI) followed by a DNA layer that is finally coated with a protective outer layer of PEI. Using fluorescein and rhodamine labeling of tRNA, PEI, and DNA, the layer-by-layer formation of the nanoparticles was visualized by fluorescent microscopy and quantitated by fluorescence spectroscopy and flow cytometry. Optimal conditions (tRNA:YCWP, PEI:YCWP ratios and DNA load levels) to synthesize YCWP encapsulated nanoparticles were determined from these results. The high in vitro transfection efficiency of this encapsulated DNA delivery technology was demonstrated by the transfection of NIH3T3-D1 cells with YCWP-tRNA/PEI/gWizGFP/PEI formulations containing low amounts of the plasmid gWizGFP per particle to maximally express green fluorescent protein (GFP).

Abstract
Background Efforts to improve the efficiency of non-viral gene delivery require a better understanding of delivery kinetics of DNA molecules into clinically relevant cells. Towards this goal, three DNA molecules were employed to investigate the effects of DNA properties on cellular delivery: a circular plasmid DNA (c-DNA), a linearized plasmid DNA (l-DNA) formulated by single-site digestion of c-DNA, and smaller linear gene cassette generated by PCR (pcr-DNA). Four non-viral gene carriers were investigated for DNA delivery: polyethyleneimine (PEI), poly-L-Lysine (PLL), palmitic acid-grafted PLL (PLL-PA), and Lipofectamine-2000™. Particle formation, binding and dissociation characteristics, and DNA uptake by rat bone marrow stromal cells were investigated. Results For individual carriers, there was no discernible difference in the morphology of particles formed as a result of carrier complexation with different DNA molecules. With PEI and PLL carriers, no difference was observed in the binding interaction, dissociation characteristics, and DNA uptake among the three DNA molecules. The presence of serum in cell culture media did not significantly affect the DNA delivery by the polymeric carriers, unlike other lipophilic carriers. Using PEI as the carrier, c-DNA was more effective for transgene expression as compared to its linear equivalent (l-DNA) by using the reporter gene for Enhanced Green Fluorescent Protein. pcr-DNA was the least effective despite being delivered into the cells to the same extent. Conclusion We conclude that the nature of gene carriers was the primary determinant of cellular delivery of DNA molecules, and circular form of the DNA was more effectively processed for transgene expression.

Abstract
Schizophyllan is a beta(1-->3)-D-glucan polysaccharide with beta(1-->6)-branched lateral glucose residues that presents a very stiff triple-helical structure under most experimental conditions. Despite the remarkable stability of this structure (which persists up to 120 degrees C in aqueous solution), schizophyllan undergoes a major change of state around 7 degrees C in water that has been hypothesized to result from an order-disorder transition in the lateral residues. This hypothesis is only supported by indirect experimental evidence and detailed knowledge (at the atomic level) concerning hydrogen-bonding networks, interactions with the solvent molecules, orientational freedom of the lateral residues, and orientational correlations among them is still lacking. In this study explicit-solvent molecular dynamics simulations of a schizophyllan fragment (complemented by simulations of its tetrasaccharide monomer) are performed at three different temperatures (273 K, 350 K, and 450 K) and with two different types of boundary conditions (finite nonperiodic or infinite periodic fragment) as an attempt to provide detailed structural and dynamical information about the triple-helical conformation in solution and the mechanism of the low-temperature transition. These simulations suggest that three important driving forces for the high stability of the triple helix are i), the limited conformational work involved in its formation; ii), the formation of a dense hydrogen-bonding network at its center; and iii), the formation of interchain hydrogen bonds between main-chain and lateral glucose residues. However, these simulations evidence a moderate and continuous variation of the simulated observables upon increasing the temperature, rather than a sharp transition between the two lowest temperatures (that could be associated with the state transition). Although water-mediated hydrogen-bonded association of neighboring lateral residues is observed, this interaction is not strong enough to promote the formation of an ordered state (correlated motions of the lateral residues), even at the lowest temperature considered.
