CoHIT: a one-pot ultrasensitive ERA-CRISPR system for detecting multiple same-site indels. Nat Commun 2024; 15:5014. [PMID: 38866774 PMCID: PMC11169540 DOI: 10.1038/s41467-024-49414-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 06/05/2024] [Indexed: 06/14/2024] Open
Abstract
Genetic testing is crucial for precision cancer medicine. However, detecting multiple same-site insertions or deletions (indels) is challenging. Here, we introduce CoHIT (Cas12a-based One-for-all High-speed Isothermal Test), a one-pot CRISPR-based assay for indel detection. Leveraging an engineered AsCas12a protein variant with high mismatch tolerance and broad PAM scope, CoHIT can use a single crRNA to detect multiple NPM1 gene c.863_864 4-bp insertions in acute myeloid leukemia (AML). After optimizing multiple parameters, CoHIT achieves a detection limit of 0.01% and rapid results within 30 minutes, without wild-type cross-reactivity. It successfully identifies NPM1 mutations in 30 out of 108 AML patients and demonstrates potential in monitoring minimal residual disease (MRD) through continuous sample analysis from three patients. The CoHIT method is also competent for detecting indels of KIT, BRAF, and EGFR genes. Integration with lateral flow test strips and microfluidic chips highlights CoHIT's adaptability and multiplexing capability, promising significant advancements in clinical cancer diagnostics.

Abstract
The CRISPR/Cas12a system is a revolutionary genome editing technique that is widely employed in biosensing and molecular diagnostics. However, there are few reports on precisely managing the trans-cleavage activity of Cas12a by simple modification since the traditional methods to manage Cas12a often require difficult and rigorous regulation of core components. Hence, we developed a novel CRISPR/Cas12a regulatory mechanism, named DNA Robots for Enzyme Activity Management (DREAM), by introducing two simple DNA robots, apurinic/apyrimidinic site (AP site) or nick on target activator. First, we revealed the mechanism of how the DREAM strategy precisely regulated Cas12a through different binding affinities. Second, the DREAM strategy was found to improve the selectivity of Cas12a for identifying base mismatch. Third, a modular biosensor for base excision repair enzymes based on the DREAM strategy was developed by utilizing diversified generation ways of DNA robots, and a multi-signal output platform such as fluorescence, colorimetry, and visual lateral flow strip was constructed. Furthermore, we extended logic sensing circuits to overcome the barrier that Cas12a could not detect simultaneously in a single tube. Overall, the DREAM strategy not only provided new prospects for programmable Cas12a biosensing systems but also enabled portable, specific, and humanized detection with great potential for molecular diagnostics.

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.

SCIENCE ADVANCES 2023; 9:eadi1965.

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.
