Harnessing intermolecular G-quadruplex-based spatial confinement effect for accelerated activation of CRISPR/Cas12a empowers ultra-sensitive detection of PML/RARA fusion genes.

[PMID: 38182385 DOI: 10.1016/j.aca.2023.342108] [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: 10/10/2023] [Revised: 12/01/2023] [Accepted: 12/02/2023] [Indexed: 01/07/2024]
Abstract
Accurate detection and classification of the three isoforms of PML/RARA genomic fragments are crucial for predicting disease progression, stratifying risk, and administering precise drug therapies in acute promyelocytic leukemia (APL). In this study, we have developed a highly specific nucleic acid detection platform capable of quantifying the long isoform of the three main PML-RARA isoforms at a constant temperature. This platform integrates the strengths of the CRISPR/Cas12a nuclease-based method and the rolling circle amplification (RCA) technique. Notably, the RCA-assisted CRISPR/Cas12a trans-cleavage system incorporates a spatial confinement effect by utilizing intermolecular G-quadruplex structures. This innovative design effectively enhances the local concentration of CRISPR/Cas12a, thereby accelerating its cleaving efficiency towards reporter nucleic acids and enabling the detection of PML/RARA fusion gene expression through spectroscopy. The robust detection of PML/RARA fusion gene from human serum samples validates the reliability and potential of this platform in the screening, diagnosis, and prognosis of APL cases. Our findings present an approach that holds significant potential for the further development of the robust CRISPR/Cas sensor system, offering a rapid and adaptable paradigm for APL diagnosis.

Abstract
Herein, we subtly engineered an amplified colorimetric biosensor for the cyclic detection of African swine fever virus DNA (ASFV-DNA), which associated the branched catalytic hairpin assembly (bCHA) amplification with G-quadruplex DNAzyme activity through triplex DNA formation. Firstly, a Y-shaped hairpin trimer was constructed for the dynamic self-assembly of DNA dendrimers. Then, in the presence of ASFV-DNA, the signal strand CP was opened, exposing the toehold regions, which would trigger the CHA cascade reaction between hairpin trimers. In the CHA cascade reaction, H1, H2, and H3 opened and bound in sequence, eventually forming the structure of DNA dendrimers. Subsequently, the obtained bCHA product was specifically recognized by the GGG repeat sequences of L1 and L2, then amplified by the synergistic effect of triplex DNA and the formation of asymmetric split G-quadruplex. Benefiting from the amplification properties of bCHA and the high peroxidase-like catalytic activity of asymmetrically split G-quadruplex DNAzymes, it could achieve effective colorimetric signal output in the presence of ASFV-DNA by means of triplex DNA formation. Under the optimal experimental conditions, this biosensor exhibited excellent sensitivity with a detection limit of 1.8 pM. Further, it was applied to the content detection of simulated samples of African swine fever, and the recoveries were 98.9 ~ 103.2%. This method has the advantages of simple operation, good selectivity, and high sensitivity, which is expected to be used for highly sensitive detection of actual samples of African swine fever virus.

Abstract
Discovery of oxidative catalysis with G-quadruplex•hemin constructs prompted a range of exciting developments in the field of biosensor design. Thus, G-quadruplex based DNAzymes with peroxidase activity found a niche as signal transduction modules in a wide range of analytical applications. The ability of nucleic acid scaffolds to recognise a variety of practically meaningful markers and to translate the recognition events into conformational changes powers numerous sensor design possibilities. In this work, we establish a catalase activity of G-quadruplex•hemin scaffolds. Catalase activated hydrogen peroxide decomposition generates molecular oxygen that forms bubbles. Observation of bubbles is a truly equipment free signal readout platform that is highly desirable in limited resources or do-it-yourself environments. We take a preliminary insight into a G-quadruplex structure-folding topology-catalase activity correlation and establish efficient operating conditions. Further, we demonstrate the platform's potential as a signal transduction modality for reporting on biomolecular recognition using an oligonucleotide as a proof-of-concept target. Ultimately, activatable catalases based on G-quadruplex•hemin scaffolds promise to become valuable contributors towards accessible molecular diagnostics applications.

Abstract
Assembly of DNA structures based on hybridization like split G-quadruplex (GQ) have great potential for the base-pair specific identification of nucleic acid targets. Herein, we combine multiple split G-quadruplex (GQ) assemblies on designed DNA nanostructures (carrier) with a solid-state nanopore sensing platform. The split GQ probes recognize various nucleic acid sequences in a parallel assay that is based on glass nanopore analysis of molecular structures. Specifically, we split a GQ into two asymmetric parts extended with sequences complementary to the target. The longer G-segment is in solution, and the shorter one is on a DNA carrier. If the target is present, the two separate GQ parts will be brought together to facilitate the split GQ formation and enhance the nanopore signal. We demonstrated detection of multiple target sequences from different viruses with low crosstalk. Given the programmability of this DNA based nanopore sensing platform, it is promising in biosensing.

Abstract
Molecular circuits have been used in a wide range of diagnosis applications, from the detection of chemical molecules in solution to the complex processing of cell surface receptors. One of the most important challenges of these systems is the lack of distinguishability between different circuit states when each circuit state represents a specific disease. In this work, we designed a molecular amplification circuit with borderline Boolean states that each state can be distinguished with different color intensity. For this purpose, two DNA complexes and four DNA hairpin structures were designed to detect miR-218 and miR-215 biomarkers. One of the designed DNA complexes has two G-quadruplex structures and the other has only one G-quadruplex structure. In the absence of the inputs, all three G-quadruplex structures are active and produce a high-intensity signal, while in the other three states, including the presence of miR-218, the presence of miR-215, and the presence of both inputs, respectively, one, two, and zero G-quadruplex structures are active. Therefore, the designed system can identify two different biomarkers simultaneously with different signal ratios, which can easily distinguish the different states of the circuit. This strategy is very promising to identify diseases in which any combination of biomarkers leads to a particular disease.

Abstract
Visual detection of ssRNA and dsDNA amplicons was achieved at room temperature without the need for a probe-analyte annealing stage. This approach uses a DNA nanostructure equipped with two analyte-binding arms. Highly selective binding of the third arm leads to the formation of a G-quadruplex structure capable of changing the solution color.

Abstract
Majority of protocols for quantitative analysis of biomarkers (including nucleic acids) require calibrations and target standards. In this work, we developed a principle for quantitative analysis that eliminates the need for a standard of a target molecule. The approach is based on stoichiometric reporting. While stoichiometry is a simple and robust analytical platform, its utility toward the analysis of biomolecules is very limited due to the lack of general methodologies for detecting the equivalence point. In this work, we engineer a new target/probe-binding model that enables detecting the equivalence point while maintaining an appropriate level of specificity. We establish the probe design principles through theoretical simulations and experimental confirmation. Further, we demonstrate the utility of the stoichiometric analysis via a proof-of-concept system based on oligonucleotide hybridization. Overall, the approach that requires neither standard nor calibration yields quantitative results with an adequate accuracy (> 90-110%) and a high specificity. The principles established in our work are very general and can extend beyond oligonucleotide targets toward quantitative analysis of many other biomolecules such as antibodies and proteins.

Abstract
DNA, a natural biological material, has become an ideal choice for biomedical applications, mainly owing to its good biocompatibility, ease of synthesis, modifiability, and especially programmability. In recent years, with the deepening of the understanding of the physical and chemical properties of DNA and the continuous advancement of DNA synthesis and modification technology, the biomedical applications based on DNA materials have been upgraded to version 2.0: through elaborate design and fabrication of smart-responsive DNA nanodevices, they can respond to external or internal physical or chemical stimuli so as to smartly perform certain specific functions. For tumor treatment, this advancement provides a new way to solve the problems of precise targeting, controllable release, and controllable elimination of drugs to a certain extent. Here, we review the progress of related fields over the past decade, and provide prospects for possible future development directions.

Abstract
The G-quadruplex structure formed by the c-myc gene sequence has attracted much attention due to its important physiological function in biology and wide application in nanotechnology. So far, probes capable of recognition of c-myc G-quadruplex with both high specificity and sensitivity are still scarce. This work presented a cyanine dye fluorescent probe named Cy-1, which has almost no fluorescence in aqueous solution, but showing more than 1000-fold fluorescence enhancement for recognizing c-myc G-quadruplex. Cy-1 also has good specificity and can selectively recognize c-myc G-quadruplex from other a variety of G-quadruplex and non-G-quadruplex structures. These properties make Cy-1 a promising probe for c-myc G-quadruplex recognition in nanotechnology or biology.

Abstract
G-triplex (G3) has been recognized as a popular intermediate during the folding of G-quadruplex (G4). This has raised interest to anticipate the ultimate formation of G3 by shortening the G4-forming oligonucleotides with the remaining three G-tracts. Some G3 structures have been validated and their stability has been found to be affected by the loop sequences similar to G4s. In this work, however, we first found that an intermolecular parallel G4 structure was preferred in K+ for the oligonucleotide 5'-TGGGTAGGGCGGG-3' (DZ3) containing only three G-tracts. We screened auramine O (AO) as the appropriate fluorophore with a molecular rotor feature to target this G4 structure. AO bound with DZ3 in a 1 : 4 ratio, as confirmed by isothermal titration calorimetry experiments, suggesting the formation of a tetramolecular G4 structure (4erG4). The excimer emission from the labelled pyrene and the DNA melting behavior at various pHs in the presence of Ag+ proved the formation of the 4erG4 structure rather than the prevalent intramolecular G3 folding. This work demonstrates that one should be cautious while putatively predicting a G3 structure from an oligonucleotide containing three G-tracts.

Abstract
The response sensitivity of a molecular sensor is determined by the folding cooperativity of its responsive module. Using an H+-responsive dimeric DNA i-motif as a model, we demonstrate the enhancement of its folding cooperativity through preorganization by a DNA framework, and with it we fabricate robust intracellular pH sensors with high response sensitivity.

Abstract
G-quadruplex (G4) is a non-canonical structure that is formed in G-rich sequences of nucleic acids. G4s play important roles in vivo, such as telomere maintenance, transcription, and DNA replication. There are three typical topologies of G4: parallel, anti-parallel, and hybrid. In general, metal cations, such as potassium and sodium, stabilize G4s through coordination in the G-quartet. While G4s have some functions in vivo, there are many reports of developed applications that use G4s. As various conformations of G4s could form from one sequence depending on varying conditions, many researchers have developed G4-based sensors. Furthermore, G4 is a great scaffold of aptamers since many aptamers folded into G4s have also been reported. However, there are some challenges about its practical use due to the difference between practical sample conditions and experimental ones. G4 conformations are dramatically altered by the surrounding conditions, such as metal cations, pH, and crowding. Many studies have been conducted to characterize G4 conformations under various conditions, not only to use G4s in practical applications but also to reveal its function in vivo. In this review, we summarize recent studies that have investigated the effects of surrounding conditions (e.g., metal cations, pH, and crowding) on G4 conformations and the application of G4s mainly in biosensor fields, and in others.

Abstract
Nucleic acids have special ability to organize themselves into various non-canonical structures, including a four-stranded DNA structure termed G-quadruplex (G4) that has been utilized for diagnostic and therapeutic applications. Herein, we report the ability of G4 to distinguish dengue virus (DENV) based on its serotypes (DENV-1, DENV-2, DENV-3 and DENV-4) using a split G4-hemin DNAzyme configuration. In this system, two separate G-rich oligonucleotides are brought together upon target DNA strand hybridization to form a three-way junction architecture, allowing the formation of a G4 structure. The G4 formation in complexation with hemin can thus provide a signal readout by generating a DNAzyme that is able to catalyze H2O2-mediated oxidation of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS). This results in a change of color providing a sensing platform for the colorimetric detection of DENV. In our approach, betaine and dimethyl sulfoxide were utilized for better G4 generation by enhancing the target-probe hybridization. In addition to this serotype-specific assay, a multi-probe cocktail assay, which is an all-in-one assay was also examined for DENV detection. The system highlights the potential of split G-quadruplex configurations for the development of DNA-based detection and serotyping systems in the future.

[PMID: 32729510 DOI: 10.1016/j.bios.2020.112385] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Revised: 06/06/2020] [Accepted: 06/09/2020] [Indexed: 02/01/2023]
Abstract
A visual cascade detection system has been applied to the detection and analysis of drug-resistance profile of Mycobacterium tuberculosis complex (MTC), a causative agent of tuberculosis. The cascade system utilizes highly selective split RNA-cleaving deoxyribozyme (sDz) sensors. When activated by a complementary nucleic acid, sDz releases the peroxidase-like deoxyribozyme apoenzyme, which, in complex with a hemin cofactor, catalyzes the color change of the sample's solution. The excellent selectivity of the cascade has allowed for the detection of point mutations in the sequences of the MTC rpoB, katG, and gyrA genes, which are responsible for resistance to rifampin, isoniazid, and fluoroquinolone, respectively. When combined with isothermal nucleic acid sequence based amplification (NASBA), the assay was able to detect amplicons of 16S rRNA and katG mRNA generated from 0.1 pg and 10 pg total RNA taken for NASBA, respectively, in less than 2 h, producing a signal detectable with the naked eye. The proposed assay may become a prototype for point-of-care diagnosis of drug resistant bacteria with visual signal output.
