Exploration of new ways for CRISPR/Cas12a activation: DNA hairpins without PAM and toehold and single strands containing DNA and RNA bases. J Biotechnol 2024; 391:99-105. [PMID: 38880387 DOI: 10.1016/j.jbiotec.2024.06.011] [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: 10/23/2023] [Revised: 06/07/2024] [Accepted: 06/13/2024] [Indexed: 06/18/2024]
Abstract
The CRISPR/Cas12a system is emerging as a promising candidate for next-generation diagnostic biosensing platforms, with the discovery of new activation modes greatly expanding its applications. Here, we have identified two novel CRISPR/Cas12a system activation modes: PAM- and toehold-free DNA hairpins, and DNA-RNA hybrid strands. Utilizing a well-established real-time fluorescence method, we have demonstrated a strong correlation between DNA hairpin structures and Cas12a activation. Compared with previously reported activation modes involving single-stranded DNA and PAM-contained double-stranded DNA, the DNA hairpin activation way exhibits similar specificity and generality. Moreover, our findings indicate that increasing the number of RNA bases in DNA-RNA hybrid strands can decelerate the kinetics of Cas12a-triggered trans-cleavage of reporter probes. These newly discovered CRISPR/Cas12a activation ways hold significant potential for the development of high-performance biosensing strategies.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 911:168708. [PMID: 37992834 DOI: 10.1016/j.scitotenv.2023.168708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 11/17/2023] [Accepted: 11/17/2023] [Indexed: 11/24/2023]
Abstract
Freshwater lead pollution has posed severe threat to the environment and human health, underscoring the urgent necessity for accurate and user-friendly detection methods. Herein, we introduce a novel Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR-Cas) sensor for highly sensitive Pb2+ detection. To accomplish this, we designed a dual-functional deoxyribozyme (df-DNAzyme) probe that functions as an activator for the CRISPR-Cas12a system while also recognizing Pb2+. The df-DNAzyme probe was subsequently combined with gold nanoparticles (AuNPs) to fabricate a DNAzyme/AuNP nanoprobe, facilitating the activation of CRISPR-Cas12a in a one-to-multiple manner. Upon exposure to Pb2+, the df-DNAzyme is cleaved, causing disintegration of the DNAzyme/AuNP nanoprobe from magnetic beads. The degraded DNAzyme/AuNP containing multiple double-stranded DNA activators efficiently triggers CRISPR-Cas12a activity, initiating cleavage of fluorescence-quenched reporter DNA and generating amplified signals accordingly. The amplified fluorescence signal is accurately quantified using a quantitative polymerase chain reaction (qPCR) instrument capable of measuring 96 or 384 samples simultaneously at the microliter scale. This technique demonstrates ultra-sensitive detection capability for Pb2+ at concentrations as low as 1 pg/L within a range from 1 pg/L to 10 μg/L, surpassing limits set by World Health Organization (WHO) and United States Environmental Protection Agency (US EPA) guidelines. This study offers an ultrasensitive and high-throughput method for the detection of Pb2+ in freshwater, thereby advancing a novel approach towards the development of precise and convenient techniques for detecting harmful contaminants.

Abstract
Mutations in mitochondrial DNA (mtDNA) play critical roles in many human diseases. In vivo visualization of cells bearing mtDNA mutations is important for resolving the complexity of these diseases, which remains challenging. Here we develop an integrated nano Cas12a sensor (InCasor) and show its utility for efficient imaging of mtDNA mutations in live cells and tumor-bearing mouse models. We co-deliver Cas12a/crRNA, fluorophore-quencher reporters and Mg2+ into mitochondria. This process enables the activation of Cas12a's trans-cleavage by targeting mtDNA, which efficiently cleave reporters to generate fluorescent signals for robustly sensing and reporting single-nucleotide variations (SNVs) in cells. Since engineered crRNA significantly increase Cas12a's sensitivity to mismatches in mtDNA, we can identify tumor tissue and metastases by visualizing cells with mutant mtDNAs in vivo using InCasor. This CRISPR imaging nanoprobe holds potential for applications in mtDNA mutation-related basic research, diagnostics and gene therapies.

Abstract
The clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein (Cas) (CRISPR/Cas) systems have recently emerged as powerful molecular biosensing tools based on their collateral cleavage activity due to their simplicity, sensitivity, specificity, and broad applicability. However, the direct application of the collateral cleavage activity for in situ intracellular detection is still challenging. Here, we debut a CRISPR/Cas-assisted nanoneedle sensor (nanoCRISPR) for intracellular adenosine triphosphate (ATP), which avoids the challenges associated with intracellular collateral cleavage by introducing a two-step process of intracellular target recognition, followed by extracellular transduction and detection. ATP recognition occurs by first presenting in the cell cytosol an aptamer-locked Cas12a activator conjugated to nanoneedles; the recognition event unlocks the activator immobilized on the nanoneedles. The nanoneedles are then removed from the cells and exposed to the Cas12a/crRNA complex, where the activator triggers the cleavage of an ssDNA fluorophore-quencher pair, generating a detectable fluorescence signal. NanoCRISPR has an ATP detection limit of 246 nM and a dynamic range from 1.56 to 50 μM. Importantly, nanoCRISPR can detect intracellular ATP in 30 min in live cells without impacting cell viability. We anticipate that the nanoCRISPR approach will contribute to broadening the biomedical applications of CRISPR/Cas sensors for the detection of diverse intracellular molecules in living systems.

Abstract
Precise killing of tumor cells without affecting surrounding normal cells is a challenge. Mitochondrial DNA (mtDNA) mutations, a common genetic variant in cancer, can directly affect metabolic homeostasis, serving as an ideal regulatory switch for precise tumor therapy. Here, we designed a mutation-induced drug release system (MIDRS), using the single-nucleotide variation (SNV) recognition ability and trans-cleavage activity of Cas12a to convert tumor-specific mtDNA mutations into a regulatory switch for intracellular drug release, realizing precise tumor cell killing. Using Ce6 as a model drug, MIDRS enabled organelle-level photodynamic therapy, triggering innate and adaptive immunity simultaneously. In vivo evaluation showed that MIDRSMT could identify tumor tissue carrying SNVs in mtDNA in unilateral, bilateral, and heterogeneous tumor models, producing an excellent antitumor effect (~82.6%) without affecting normal cells and thus resulting in a stronger systemic antitumor immune response. Additionally, MIDRS was suitable for genotype-specific precision drug release of chemotherapeutic drugs. This strategy holds promise for mutation-specific personalized tumor treatment approaches.

Abstract
Non-nucleic acid targets have posed a serious challenge to food safety. The detection of non-nucleic acid targets can enable us to monitor food contamination in a timely manner. In recent years, the CRISPR/Cas system has been extensively explored in biosensing. However, there is a lack of a summary of CRISPR/Cas-powered detection tailored to non-nucleic acid targets involved in food safety. This review comprehensively summarizes the recent advances on the construction of CRISPR/Cas-powered detection and the promising applications in the field of food safety related non-nucleic acid targets. The current challenges and futuristic perspectives are also proposed accordingly. The rapidly evolving CRISPR/Cas system has provided a powerful propellant for non-nucleic acid target detection via integration with aptamer and/or DNAzyme. Compared with traditional analytical methods, CRISPR/Cas-powered detection is conceptually novel, essentially eliminates the dependence on large instruments, and also demonstrates the capability for rapid, accurate, sensitive, and on-site testing.

Abstract
Next-generation biosensing tools based on CRISPR/Cas have revolutionized the molecular detection. A number of CRISPR/Cas-based biosensors have been reported for the detection of nucleic acid targets. The establishment of efficient methods for non-nucleic acid target detection would further broaden the scope of this technique, but up to now, the concerning research is limited. In the current study, we reported a versatile biosensing platform for non-nucleic acid small-molecule detection called SMART-Cas12a (small-molecule aptamer regulated test using CRISPR/Cas12a). Simply, hybridization chain reaction cascade signal amplification was first trigged by functional nucleic acid (aptamer) through target binding. Then, the CRISPR/Cas system was integrated to recognize the amplified products followed by activation of the trans-cleavage. As such, the target can be ingeniously converted to nucleic acid signals and then fluorescent signals that can be readily visualized and analyzed by a customized 3D-printed visualizer with the help of a home-made App-enabled smartphone. Adenosine triphosphate was selected as a model target, and under the optimized conditions, we achieved fine analytical performance with a linear range from 0.1 to 750 μM and a detection limit of 1.0 nM. The satisfactory selectivity and recoveries that we have obtained further demonstrated this method to be suitable for a complex sample environment. The sample-to-answer time was less than 100 min. Our work not only expanded the reach of the CRISPR-Cas system in biosensing but also provided a prototype method that can be generalized for detecting a wider range of analytes with desirable adaptability, sensitivity, specificity, and on-site capability.

Abstract
Timely identification of human papillomavirus (HPV) infection is crucial for the prevention of cervical cancer. Current HPV detection methods mainly rely on polymerase chain reaction (PCR), which often requires bulky equipment and a long assay time. In this work, we report a heating-membrane-assisted multiplexed microfluidics platform that couples recombinase polymerase amplification (RPA) and CRISPR technology (termed M3-CRISPR) for fast and low-cost detection of multiple HPV subtypes. The heating membrane can provide convenient temperature control for the on-chip RPA and CRISPR assays. This stand-alone system allows simultaneous detection of HPV16 and HPV18 with high specificity and detection sensitivity (0.5 nM and 1 × 10-18 M for unamplified and amplified plasmids, respectively) in 30 min with a fluorescence-based readout. Furthermore, we introduced an optimized lateral flow dipstick (LFD) into the portable system to allow visualized detection of HPV DNA. The LFD-based readout also reached a detection sensitivity of 1 × 10-18 M for amplified plasmids and realized successful detection of HPV subtypes in the clinical samples. Finally, we established an automatic microfluidic system that enables the sample-in-answer-out detection of HPV subtypes. We believe that this fast, convenient, and affordable molecular diagnostic platform can serve as a useful tool in point-of-care testing of HPV or other pathogens.

Abstract
CRISPR/Cas systems are novel gene editing tools with tremendous capacity and accuracy for gene editing and hold great potential for therapeutic genetic manipulation. However, the lack of safe and efficient delivery methods for CRISPR/Cas and its guide RNA hinders their wide adoption for therapeutic applications. To this end, there is an increasing demand for safe, efficient, precise, and non-pathogenic delivery approaches, both in vitro and in vivo. With the convergence of nanotechnology and biomedicine, functional nanocomposites have demonstrated unparalleled sophistication to overcome the limits of CRISPR/Cas delivery. The tunability of the physicochemical properties of nanocomposites makes it very easy to conjugate them with different functional substances. The combinatorial application of diverse functional materials in the form of nanocomposites has shown excellent properties for CRISPR/Cas delivery at the target site with therapeutic potential. The recent highlights of selective organ targeting and phase I clinical trials for gene manipulation by CRISPR/Cas after delivery through LNPs are at the brink of making it to routine clinical practice. Here we summarize the recent advances in delivering CRISPR/Cas systems through nanocomposites for targeted delivery and therapeutic genome editing.

Abstract
The global corona virus disease 2019 (COVID-19) has been announced a pandemic outbreak, and has threatened human life and health seriously. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as its causative pathogen, is widely detected in the screening of COVID-19 patients, infected people and contaminated substances. Lateral flow assay (LFA) is a popular point-of-care detection method, possesses advantages of quick response, simple operation mode, portable device, and low cost. Based on the above advantages, LFA has been widely developed for detecting SARS-CoV-2. In this review, we summarized the articles about the sandwich mode LFA detecting SARS-CoV-2, classified according to the target detection objects indicating genes, nucleocapsid protein, spike protein, and specific antibodies of SARS-CoV-2. In each part, LFA is further classified and summarized according to different signal detection types. Additionally, the properties of the targets were introduced to clarify their detection significance. The review is expected to provide a helpful guide for LFA sensitization and marker selection of SARS-CoV-2.

Abstract
Near-infrared (NIR)-light-triggered nanomedicine, including photodynamic therapy (PDT) and photothermal therapy (PTT), is growing an attractive approach for cancer therapy due to its high spatiotemporal controllability and minimal invasion, but the tumor eradication is limited by the intrinsic anti-stress response of tumor cells. Herein, we fabricate a tumor-microenvironment responsive CRISPR nanoplatform based on oxygen-deficient titania (TiO2-x ) for mild NIR-phototherapy. In tumor microenvironment, the overexpressed hyaluronidase (HAase) and glutathione (GSH) can readily destroy hyaluronic acid (HA) and disulfide bond and releases the Cas9/sgRNA from TiO2-x to target the stress alleviating regulators, i.e., nuclear factor E2-related factor 2 (NRF2) and heat shock protein 90α (HSP90α), thereby reducing the stress tolerance of tumor cells. Under subsequent NIR light illumination, the TiO2-x demonstrates a higher anticancer effect both in vitro and in vivo. This strategy not only provides a promising modality to kills cancer cells in a minimal side-effects manner by interrupting anti-stress pathways but also proposes a general approach to achieve controllable gene editing in tumor region without unwanted genetic mutation in normal environments.

Abstract
Bacterial genotyping is important for understanding the complex microbiota. Although fluorescence in situ hybridization (FISH) has enabled bacterial community identification with high spatial resolution, its unavoidable cell fixation steps and signal generation by multi-probe stacking greatly limit its application in living bacterial genotyping. Here, we designed polyethyleneimine-encapsulated CRISPR/Cas12a-circular reporter nanoprobes (CasCLR) for rapid and sensitive visualization of gene information in living bacteria. We found that, nanoprobe-based sequential delivery of Cas12a/crRNA and circular reporter into bacteria allowed single genomic loci to initiate trans-cleavage activity of Cas12a, thereby cleaving CLR to generate amplified fluorescent signals for imaging of target gene. Using CasCLR, we can sensitively analyze the percentage of target bacteria in co-culture experiments and directly detect pathogenic bacteria in uncultured mouse gut microbe. In addition, CasCLR has the ability to sensitively analyze specific genotype of microbial communities in vivo. This nanobiotechnology-based bacterial gene analysis is expected to advance understanding of in vivo bacterial cytogenetic information.
