Abstract
Synthetic DNA-protein conjugates have found widespread applications in diagnostics and therapeutics, prompting a growing interest in developing chemical biology methodologies for the precise and site-specific preparation of covalent DNA-protein conjugates. In this review article, we concentrate on techniques to achieve precise control over the structural and site-specific aspects of DNA-protein conjugates. We summarize conventional methods involving unnatural amino acids and self-labeling proteins, accompanied by a discussion of their potential limitations. Our primary focus is on introducing HUH endonuclease as a novel generation of fusion protein tags for DNA-protein conjugate preparation. The detailed conjugation mechanisms and structures of representative endonucleases are surveyed, showcasing their advantages as fusion protein tag in sequence selectivity, biological orthogonality, and no requirement for DNA modification. Additionally, we present the burgeoning applications of HUH-tag-based DNA-protein conjugates in protein assembly, biosensing, and gene editing. Furthermore, we delve into the future research directions of the HUH-tag, highlighting its significant potential for applications in the biomedical and DNA nanotechnology fields.

[PMID: 37455088 DOI: 10.1016/j.aca.2023.341580] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/28/2023] [Accepted: 06/29/2023] [Indexed: 07/18/2023]
Abstract
Traditional immunoassay methods often face challenges due to the labeling procedure of protein enzymes, the use of multiple antibodies, and severe conditions. To address these limitations, we propose the concept of incorporating branchedzyme-powered nanodevices into immunoassays. In this strategy, multiple DNAzymes are localized onto gold nanoparticles (AuNPs) along with substrates. The localization format facilitates intramolecular reactions between DNAzymes and substrates, leading to accelerated kinetics of the nanodevice. Upon the formation of an immunocomplex with an antibody on a 96-well plate, the branchedzyme-powered nanodevice catalytically releases multiple fluorescent signals under ambient temperature, eliminating the need for secondary antibodies. The branched DNAzymes exhibit catalytic properties similar to those of protein enzymes, thus simplifying the assay procedure and achieving isothermal detection. Furthermore, the detection process can be controlled by the addition or deletion of cofactors. Additionally, the affinity ligand can be easily modified to construct nanodevices specific to different targets without requiring extensive redesign. This strategy has demonstrated successful quantification of tumor biomarkers such as alpha-fetoprotein (AFP) and prostate-specific antigen (PSA) at subpicomolar concentrations, showcasing its suitability for clinical applications. Consequently, the branchedzyme-powered nanodevice represents a valuable addition to the immunoassay toolbox, opening new possibilities for clinical diagnostics.

Abstract
Endothelial cell injury plays a critical part in ischemic acute kidney injury (AKI) and participates in the progression of AKI. Targeting renal endothelial cell therapy may ameliorate vascular injury and further improve the prognosis of ischemic AKI. Here, P-selectin as a biomarker of ischemic AKI in endothelial cells is identified and P-selectin binding peptide (PBP)-engineered extracellular vesicles (PBP-EVs) with imaging and therapeutic functions are developed. The results show that PBP-EVs exhibit a selective targeting tendency to injured kidneys, while providing spatiotemporal information for the early diagnosis of AKI by quantifying the expression of P-selectin in the kidneys by molecular imaging. Meanwhile, PBP-EVs reveal superior nephroprotective functions in the promotion of renal repair and inhibition of fibrosis by alleviating inflammatory infiltration, improving reparative angiogenesis, and ameliorating maladaptive repair of the renal parenchyma. In conclusion, PBP-EVs, as an ischemic AKI theranostic system that is designed in this study, provide a spatiotemporal diagnosis in the early stages of AKI to help guide personalized therapy and exhibit superior nephroprotective effects, offering proof-of-concept data to design EV-based theranostic strategies to promote renal recovery and further improve long-term outcomes following AKI.

Specific intracellular binding peptide as sPD-L1 antibody mimic: Robust binding capacity and intracellular region specific modulation upon applied to sensing research.

Abstract
Programmed death ligand 1 (PD-L1) immune checkpoint has been regarded as a new target for predicting cancer immunotherapy. As a transmembrane protein, PD-L1 has very low blood concentration and is likely to deplete their native activity when separated from the membrane environment due to significant hydrophobic domains, which make it difficult to measure sensitively. The reported PD-L1 aptamers and antibodies are both extracellular region binding molecules with the overlapping binding sites, which seriously limit with the construction of biosensor. Specific intracellular binding peptide (SIBP) as a unique PD-L1 intracellular region homing probe molecule is utilized for specifically capture targets. A simple and sensitive surface plasmon resonance (SPR) sandwich assay was constructed to detect serum soluble PD-L1 (sPD-L1) based on the unique and strong binding ability of SIBP to the intracellular region of sPD-L1. The designed SPR sensor showed great selectivity and wide dynamic response range of sPD-L1 concentration from 10 ng/mL to 2000 ng/mL. The limit of detection was calculated to be 1.749 ng/mL (S/N = 3). Owing to the SIBP's strong and specific binding ability with sPD-L1, the sensitive sensor can successfully detect sPD-L1 in serum samples, paving the way for the development of efficient test tools for clinical diagnosis and analysis.

Abstract
Aptamer-based electrochemical sensors have gained attention in the context of developing a diagnostic biomarker detection method because of their rapid response, miniaturization ability, stability, and design flexibility. In such detection systems, enzymes are often used as labels to amplify the electrochemical signal. We have focused on glucose dehydrogenase (GDH) as a labeling enzyme for electrochemical detection owing to its high enzymatic activity, availability, and well-established electrochemical principle and platform. However, it is difficult and laborious to obtain one to one labeling of a GDH-aptamer complex with conventional chemical conjugation methods. In this study, we used GDH that was genetically fused to a DNA binding protein, i.e., zinc finger protein (ZF). Fused GDH can be attached to an aptamer spontaneously and site specifically in a buffer by exploiting the sequence-specific binding ability of ZF. Using such a fusion protein, we labeled a vascular endothelial growth factor (VEGF)-binding aptamer with GDH and detected the target electrochemically. As a result, upon the addition of glucose, the GDH labeled on the aptamer generated an amperometric signal, and the current response increased dependent on the VEGF concentration. Eventually, the developed electrochemical sensor proved to detect VEGF levels as low as 105 pM, thereby successfully demonstrating the concept of using ZF-fused GDH to enzymatically label aptamers.

Targeted Repair of Vascular Injury by Adipose-Derived Stem Cells Modified with P-Selectin Binding Peptide. ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2020; 7:1903516. [PMID: 32537407 PMCID: PMC7284211 DOI: 10.1002/advs.201903516] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 02/26/2020] [Accepted: 03/12/2020] [Indexed: 05/18/2023]
Abstract
Percutaneous coronary intervention for coronary artery disease treatment often results in pathological vascular injury, characterized by P-selectin overexpression. Adipose-derived stem cells (ADSCs) therapeutic efficacy remains elusive due to poor ADSCs targeting and retention in injured vessels. Here, conjugated P-selectin binding peptide (PBP) to polyethylene glycol-conjugated phospholipid derivative (DMPE-PEG) linkers (DMPE-PEG-PBP; DPP) are used to facilitate the modification of PBP onto ADSCs cell surfaces via hydrophobic interactions between DMPE-PEG and the phospholipid bilayer. DPP modification neither has influence on ADSCs proliferation nor apoptosis/paracrine factor gene expression. A total of 5 × 10-6 m DPP-modified ADSCs (DPP-ADSCs) strongly binds to P-selectin-displaying activated platelets and endothelial cells (ECs) in vitro and to wire-injured rat femoral arteries when administered by intra-arterial injection. Targeted binding of ADSCs shields injury sites from platelet and leukocyte adhesion, thereby decreasing inflammation at injury sites. Furthermore, targeted binding of ADSCs recovers injured ECs functionality and reduces platelet-initiated vascular smooth muscle cells (VSMCs) chemotactic migration. Targeted binding of DPP-human ADSCs to balloon-injured human femoral arteries is also demonstrated in ex vivo experiments. Overall, DPP-ADSCs promote vascular repair, inhibit neointimal hyperplasia, increase endothelium functionality, and maintain normal VSMCs alignment, supporting preclinical noninvasive utilization of DPP-ADSCs for vascular injury.

Abstract
Antibody-DNA conjugates are powerful tools for DNA-assisted protein analysis. Growing usage of these methods demands efficient production of high-quality conjugates. We developed an easy and fast synthesis route yielding covalent antibody-DNA conjugates with a defined conjugation site and low batch-to-batch variability. We utilize the Z domain from protein A, containing the unnatural amino acid 4-benzoylphenylalanine (BPA) for photoaffinity labeling of the antibodies' Fc region. Z(xBPA) domains are C-terminally modified with triple-glycine (G3)-modified DNA-oligonucleotides via enzymatic Sortase A coupling. We show reliable modification of the most commonly used IgG's. To prove our conjugates' functionality, we detected antibody-antigen binding events in an assay called Droplet Barcode Sequencing for Protein analysis (DBS-Pro). It confirms not only retained functionality for both conjugate parts but also the potential of using DBS-Pro for quantifying protein abundances. As intermediates are easily storable and our approach is modular, it offers a convenient strategy for screening various antibody-DNA conjugates using the same starting material.

Abstract
In this work, a novel and signal-amplified label-free electrochemical aptasensor was developed and enabled efficient determination of γ-interferon (IFN-γ), based on target-induced DNA strand transform of hairpin-to-linear conformation combining with simultaneous capture of redox probe and target. Gold nanoparticles (AuNPs) were electrodeposited in the matrix of poly(amidoamine) dendrimer (PAMAM), followed by drop-casting addition on MoS2 nanosheets to prepare AuNPs- PAMAM/MoS2 composites. HS-terminated hairpin-DNA aptamer of IFN-γ was conjugated with AuNPs to prepare aptamer-AuNPs-PAMAM/MoS2 onto glassy carbon electrode (GCE), by using bovine serum albumin as the cross-linker and stabilizer. Methylene blue (MB) as a redox probe was absorbed on IFN-γ aptamer. In the presence of IFN-γ, MB electrochemical signal increased gradually. The preparation processes, mechanisms and optimal experiment conditions of aptamer- AuNPs-PAMAM/MoS2/MB/GCE sensing platform were studied by electron microscope imaging technologies, spectral curves and electrochemical measurements. There is a well plotting linear relationship between the peak current intensities of MB and IFN-γ contents in the range of 0.01-1000 pg mL-1, showing a low detection limit of 2 fg mL-1. Experimental results testified that the aptasensor had highly sensitive and selective responses toward IFN-γ, over potential interferents. In real biological samples, the aptasensor of IFN-γ had superior detection recoveries, indicating its high detection performance and feasibility for practicability.

Abstract
Modification of protein-based drug carriers with tumor-targeting properties is an important area of research in the field of anticancer drug delivery. To this end, we developed nanoparticles comprised of elastin-like polypeptides (ELPs) with fused poly-aspartic acid chains (ELP-D) displaying DNA aptamers. DNA aptamers were enzymatically conjugated to the surface of the nanoparticles via genetic incorporation of Gene A* protein into the sequence of the ELP-D fusion protein. Gene A* protein, derived from bacteriophage ϕX174, can form covalent complexes with single-stranded DNA via the latter's recognition sequence. Gene A* protein-displaying nanoparticles exhibited the ability to deliver the anticancer drug paclitaxel (PTX), whilst retaining activity of the conjugated Gene A* protein. PTX-loaded protein nanoparticles displaying DNA aptamers known to bind to the MUC1 tumor marker resulted in increased cytotoxicity with MCF-7 breast cancer cells compared to PTX-loaded protein nanoparticles without the DNA aptamer modification.

Abstract
Herein, an aptamer-initiated on-particle template-independent enzymatic polymerization (aptamer-OTEP) strategy for electrochemical aptasensor (E-aptasensor) is developed for analysis of cancer biomarker carcino-embryonic antigen (CEA). A pair of DNA aptamers is employed which can be specifically bond with CEA simultaneously. One of the aptamer is thiolated at 3'-terminal and immobilized onto the gold electrode as a capture probe, while the other one has a thiol group at its 5'-terminal and is modified onto the gold nanoparticles surface to form a nanoprobe. In the present of target, the two aptamers can "sandwich" the target, thus the nanoprobe is attached to the electrode. Then terminal deoxynucleotidyl transferase (TdT) is employed to catalyze the incorporation of biotin labeled dNTPs into the 3'-OH terminals of the DNA aptamer on the nanoprobe. The as-generated long DNA oligo tentacles allow specific binding of numerous avidin modified horseradish peroxidase (Av-HRP), resulting in tens of thousands of HRP catalyzed reduction of hydrogen peroxide and sharply increasing electrochemical signals. Taking advantage of the enzyme based nucleic acid amplification and nanoprobe, this strategy is demonstrated to possess the outstanding amplification efficiency.

Abstract
Isothermal amplification of nucleic acids is a simple process that rapidly and efficiently accumulates nucleic acid sequences at constant temperature. Since the early 1990s, various isothermal amplification techniques have been developed as alternatives to polymerase chain reaction (PCR). These isothermal amplification methods have been used for biosensing targets such as DNA, RNA, cells, proteins, small molecules, and ions. The applications of these techniques for in situ or intracellular bioimaging and sequencing have been amply demonstrated. Amplicons produced by isothermal amplification methods have also been utilized to construct versatile nucleic acid nanomaterials for promising applications in biomedicine, bioimaging, and biosensing. The integration of isothermal amplification into microsystems or portable devices improves nucleic acid-based on-site assays and confers high sensitivity. Single-cell and single-molecule analyses have also been implemented based on integrated microfluidic systems. In this review, we provide a comprehensive overview of the isothermal amplification of nucleic acids encompassing work published in the past two decades. First, different isothermal amplification techniques are classified into three types based on reaction kinetics. Then, we summarize the applications of isothermal amplification in bioanalysis, diagnostics, nanotechnology, materials science, and device integration. Finally, several challenges and perspectives in the field are discussed.

Abstract
Small peptide can be used as an effective biological recognition element and provide an alternative tool for protein detection. However, the development of peptide-based detecting strategy still remains elusive due to the difficulty of signal transduction. Herein, we report a peptide-based colorimetric strategy for the detection of disease biomarker by using vascular endothelial growth factor receptor 1 (Flt-1) as an example. In this strategy, N-terminal aromatic residue-containing peptide modified gold nanoparticles (GNPs) can form bulky aggregate by the introduction of cucurbit[8]uril (CB[8]) that can selectively accommodate two N-terminal aromatic residue of peptides simultaneously regardless of their sequences. However, in the presence of Flt-1, the peptide can specifically bind to the protein molecule and the N-terminal aromatic residue will be occupied, resulting in little aggregation of GNPs. By taking advantage of the highly affinitive peptide and efficiency cross-linking effect of CB[8] to GNPs, colorimetric assay for protein detection can be achieved with a detection limit of 0.2 nM, which is comparable with traditional methods. The feasibility of our method has also been demonstrated in spiked serum sample, indicating potential application in the future.

Abstract
In synthetic biology, "understanding by building" requires exquisite control of the molecular constituents and their spatial organization. Site-specific coupling of DNA to proteins allows arrangement of different protein functionalities with emergent properties by self-assembly on origami-like DNA scaffolds or by direct assembly via Single-Molecule Cut & Paste (SMC&P). Here, we employed the ybbR-tag/Sfp system to covalently attach Coenzyme A-modified DNA to GFP and, as a proof of principle, arranged the chimera in different patterns by SMC&P. Fluorescence recordings of individual molecules proved that the proteins remained folded and fully functional throughout the assembly process. The high coupling efficiency and specificity as well as the negligible size (11 amino acids) of the ybbR-tag represent a mild, yet versatile, general and robust way of adding a freely programmable and highly selective attachment site to virtually any protein of interest.

Abstract
Protein-binding peptide is recently recognized as an effective artificial affinity reagent for protein assays. However, its application is hampered by the limited choices of available signal readout methods. Herein, we report a general electrochemical signal readout method for protein-binding peptides exploiting the host-guest chemistry of cucurbituril. Via the formation of supermolecules among cucurbituril, electrochemical reporter, and the peptide, a protein-binding peptide can be noncovalently coupled with the electrochemical reporter. To assay the target protein, the protein-binding peptides are first self-assembled in the sensing layer, and after the capturing of the target protein, a portion of the peptides become protein-bound. The protein-free peptides are then coupled with the electrochemical reporter to yield a signal readout inversely proportional to the amount of the captured target proteins. Since the only requirement of supermolecule formation is the incorporation of aromatic amino acids in the peptide sequence, this strategy is universally applicable to many protein-binding peptides. The generality and target specificity of the proposed method are successfully demonstrated in the assays of two kinds of target proteins: tumor necrosis factor-α and amyloid β 1-42 soluble oligomer, respectively. The feasibility of our method is also tested in the monitoring of tumor necrosis factor-α secretion activity of HL-60 cells. These results indicate that our method can have great use in protein detection in the future.
