Biosens Bioelectron 2024; 264:116687. [PMID: 39173337 DOI: 10.1016/j.bios.2024.116687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Revised: 08/08/2024] [Accepted: 08/18/2024] [Indexed: 08/24/2024]
Abstract
Uracil-DNA glycosylase (UDG), an enzyme for repairing uracil-containing DNA damage, is crucial for maintaining genomic stability. Simple and fast quantification of UDG activity is essential for biological assay and clinical diagnosis, since its aberrant level is associated with DNA damage and various diseases. Herein, we developed a fully integrated "sample in-signal out" distance-based paper analytical device (dPAD) for visual quantification of UDG using a flow-controlled uracil-rich DNA hydrogel (URDH). The uracil base sites contained in the DNA hydrogel are mis-incorporated with dUTP by rolling circle amplification (RCA), which simplifies the preparation process of the functionalized hydrogel. In the presence of UDG, the uracil in URDH can be recognized and removed to induce the permeability change of URDH, resulting in the visible distance signal along the paper channel. Using dPAD, as low as 6.4 × 10-4 U/mL of UDG (within 80 min) is visually identified without any instruments and complicated operations. This integrated dPAD is advantageous for its simplicity, cost effectiveness, and ease of use. We envision that it has the great potential for point-of-care testing (POCT) in DNA damage testing, personalized healthcare assessment, and biomedical applications.

Abstract
The efficient preparation of single-stranded DNA (ssDNA) rings, as a macromolecular construction approach with topological features, has aroused much interest due to the ssDNA rings' numerous applications in biotechnology and DNA nanotechnology. However, an extra splint is essential for enzymatic circularization, and by-products of multimers are usually present at high concentrations. Here, we proposed a simple and robust strategy using permuted precursor (linear ssDNA) for circularization by forming an intramolecular dynamic nick using a part of the linear ssDNA substrate itself as the template. After the simulation of the secondary structure for desired circular ssDNA, the linear ssDNA substrate is designed to have its ends on the duplex part (≥5 bp). By using this permuted substrate with 5'-phosphate, the splint-free circularization is simply carried out by T4 DNA ligase. Very interestingly, formation of only several base pairs (2-4) flanking the nick is enough for ligation, although they form only instantaneously under ligation conditions. More significantly, the 5-bp intramolecular duplex part commonly exists in genomes or functional DNA, demonstrating the high generality of our approach. Our findings are also helpful for understanding the mechanism of enzymatic DNA ligation from the viewpoint of substrate binding.

Abstract
The direct use of mesenchymal stem cells (MSCs) as therapeutics for skin injuries is a promising approach, yet it still faces several obstacles, including limited adhesion, retention, and engraftment of stem cells in the wound area, as well as impaired regenerative and healing functions. Here, DNA-based self-assembled composites are reported that can aid the adhesion of MSCs in skin wounds, enhance MSC viability, and accelerate wound closure and re-epithelialization. Rolling-circle amplification (RCA)-derived DNA flowers, equipped with multiple copies of cyclic Arg-Gly-Asp (cRGD) peptides and anti-von Willebrand factor (vWF) aptamers, act as robust scavengers of reactive oxygen species (ROS) and enable synergistic recognition and adhesion to stem cells and damaged vascular endothelial cells. These DNA structure-aided stem cells are retained at localized wound sites, maintain repair function, and promote angiogenesis and growth factor secretion. In both normal and diabetes-prone db/db mice models with excisional skin injuries, facile topical administration of DNA flower-MSCs elicits rapid blood vessel formation and enhances the sealing of the wound edges in a single dose. DNA composite-engineered stem cells warrant further exploration as a new strategy for the treatment of skin and tissue damage.

Abstract
BACKGROUND The design of DNA materials with specific nanostructures for biomedical tissue engineering applications remains a challenge. High-dimensional DNA nanomaterials are difficult to prepare and are unstable; moreover, their synthesis relies on heavy metal ions. Herein, we developed a bimodal DNA self-origami material with good biocompatibility and differing functions using a simple synthesis method. We simulated and characterized this material using a combination of oxDNA, freeze-fracture electron microscopy, and atomic force microscopy. Subsequently, we optimized the synthesis procedure to fix the morphology of this material. RESULTS Using molecular dynamics simulation, we found that the bimodal DNA self-origami material exhibited properties of spontaneous stretching and curling and could be fixed in a single morphology via synthesis control. The application of different functional nucleic acids enabled the achievement of various biological functions, and the performance of functional nucleic acids was significantly enhanced in the material. Consequently, leveraging the various functional nucleic acids enhanced by this material will facilitate the attainment of diverse biological functions. CONCLUSION The developed design can comprehensively reveal the morphology and dynamics of DNA materials. We thus report a novel strategy for the construction of high-dimensional DNA materials and the application of functional nucleic acid-enhancing materials.

Abstract
We designed and synthesized a set of four 2'-deoxyribonucleoside 5'-O-triphosphates (dNTPs) derived from 5-substituted pyrimidines and 7-substituted 7-deazapurines bearing anionic substituents (carboxylate, sulfonate, phosphonate, and phosphate). The anion-linked dNTPs were used for enzymatic synthesis of modified and hypermodified DNA using KOD XL DNA polymerase containing one, two, three, or four modified nucleotides. The polymerase was able to synthesize even long sequences of >100 modified nucleotides in a row by primer extension (PEX). We also successfully combined two anionic and two hydrophobic dNTPs bearing phenyl and indole moieties. In PCR, the combinations of one or two modified dNTPs gave exponential amplification, while most of the combinations of three or four modified dNTPs gave only linear amplification in asymmetric PCR. The hypermodified ONs were successfully re-PCRed and sequenced by Sanger sequencing. Biophysical studies including hybridization, denaturation, CD spectroscopy and molecular modelling and dynamics suggest that the presence of anionic modifications in one strand decreases the stability of duplexes while still preserving the B-DNA conformation, whilst the DNA hypermodified in both strands adopts a different secondary structure.

Abstract
Despite the vast interest in utilizing rolling circle amplification (RCA)-based DNA networks for bioapplications, precise control of the mechanical and physicochemical properties is highly challenging. To address this concern, we aimed to develop ultrasoft self-supporting polymerized DNA networks (pDNets) of variable crystallinities to manipulate sequence-mediated drug release efficiency. A controlled ratio of the inorganic magnesium pyrophosphate (MgPPi) crystal to the organic polymeric DNA resulted in the synthesis of pDNets of various nanoporosities. The number of crystal microstructures influencing drug localization and release pattern and the tunable mechanical properties influencing injectability and structural stability under physiological conditions were investigated. The pDNets exhibited ultrasoft properties with Young's moduli of 0.06-0.54 Pa; approximately 9-fold differences in mechanical properties were obtained by varying the degree of crystallinity. With functional DNA sequences, the developed platforms showed pH stimuli-responsive drug release profiles of the dynamic DNA structures and aptamer-specific cell target adhesion efficiency. Analyses of controlled delivery of anticancer therapeutics in vitro and in vivo revealed crystallinity-dependent antitumor efficacy without side effects. This strategy provides an effective one-pot enzymatic polymerization methodology and a favorable microenvironment for a three-dimensional DNA network based on demand-localized drug delivery.

Abstract
Nucleic acids have been extensively modified in different moieties to expand the scope of genetic materials in the past few decades. While the development of unnatural base pairs (UBPs) has expanded the genetic information capacity of nucleic acids, the production of synthetic alternatives of DNA and RNA has increased the types of genetic information carriers and introduced novel properties and functionalities into nucleic acids. Moreover, the efforts of tailoring DNA polymerases (DNAPs) and RNA polymerases (RNAPs) to be efficient unnatural nucleic acid polymerases have enabled broad application of these unnatural nucleic acids, ranging from production of stable aptamers to evolution of novel catalysts. The introduction of unnatural nucleic acids into living organisms has also started expanding the central dogma in vivo. In this article, we first summarize the development of unnatural nucleic acids with modifications or alterations in different moieties. The strategies for engineering DNAPs and RNAPs are then extensively reviewed, followed by summarization of predominant polymerase mutants with good activities for synthesizing, reverse transcribing, or even amplifying unnatural nucleic acids. Some recent application examples of unnatural nucleic acids with their polymerases are then introduced. At the end, the approaches of introducing UBPs and synthetic genetic polymers into living organisms for the creation of semi-synthetic organisms are reviewed and discussed.
