Chen L, You S, Wang X, Li D, Ren S, Chen L. Dual carminic acid/hemin-marked DNA probes for simultaneously detecting CV-A16 and EV-A71 based on the mechanism of dimer to monomer transition. Talanta 2023; 265:124884. [PMID: 37392710 DOI: 10.1016/j.talanta.2023.124884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 06/09/2023] [Accepted: 06/25/2023] [Indexed: 07/03/2023]
Abstract
This study aimed to prepare two hairpin-structure DNA probes by conjugating carminic acid (CA) or hemin into two ends of specific genes of coxsackievirus A16 (CV-A16) and enterovirus A71 (EV-A71) (probeCV-A16-CA and probeEV-A71-hemin). Then, probeCV-A16-CA and probeEV-A71-hemin as the signal molecules were adsorbed onto NH2-MIL-53 (Al) (MOF). Based on these biocomposites, an electrochemical biosensor with dual-signal outputs for simultaneous assay of CV-A16 and EV-A71 was constructed. The stem-loops of probes switched both CA and hemin monomer to dimer, reducing the electrical activity of both CA and hemin. Subsequently, the target-induced opening of the stem-loop switched both CA and hemin dimers to monomers, resulting in two nonoverlapping increasing electrical signals. This sensitively reflected the concentration of targetCV-A16 and targetEV-A17 ranging from 10-10 to 10-15 M with a detection limit of 0.19 and 0.24 fM. This strategy was mainly applied to the simultaneous determination of targetCV-A16 and targetEV-A17 in 100% serum with satisfactory results. The MOF combined with the high loading capacity broke through the intrinsic limitation on sensitivity using the traditional methods. An increase of three orders of magnitude was observed. This study involved simple one-step detection, and only a simple replacement of a gene could trigger its potential in clinical and diagnostic applications.

Abstract
The detection of nucleic acids has become significantly important in molecular diagnostics, gene therapy, mutation analysis, forensic investigations and biomedical development, and so on. In recent years, exonuclease III (Exo III) as an enzyme in the 3'-5' exonuclease family has evolved as a frequently used technique for signal amplification of low level DNA target detection. Different from the traditional target amplification strategies, the Exo III-assisted amplification strategy has been used for target DNA detection through directly amplifying the amounts of signal reagents. The Exo III-assisted amplification strategy has its unique advantages and characters, because the character of non-specific recognition of Exo III can overcome the limitation of a target-to-probe ratio of 1 : 1 in the traditional nucleic acid hybridization assay and acquire higher sensitivity. In this review, we selectively discuss the recent advances in the Exo III-assisted amplification strategy, including the amplification strategy integrated with nanomaterials, biosensors, hairpin probes and other nucleic acid detection methods. We also discuss the strengths and limitations of each strategy and methods to overcome the limitations.

All-in-one approaches for rapid and highly specific quantifcation of single nucleotide polymorphisms based on ligase detection reaction using molecular beacons as turn-on probes. Talanta 2020; 224:121717. [PMID: 33378999 DOI: 10.1016/j.talanta.2020.121717] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Revised: 09/17/2020] [Accepted: 09/28/2020] [Indexed: 11/27/2022]
Abstract
Rapid, simple, specific and sensitive approaches for single nucleotide polymorphisms (SNPs) detection are essential for clinical diagnosis. In this study, all-in-one approaches, consisting of the whole detection process including ligase detection reaction (LDR) and real time quantitative polymerase chain reaction performed in one PCR tube by a one-step operation on a real-time PCR system using molecular beacon (MB) as turn-on probe, were developed for rapid, simple, specific and sensitive quantifcation of SNPs. High specificity of the all-in-one approach was achieved by using the LDR, which employs a thermostable and single-base discerning Hifi Taq DNA ligase to ligate adjacently hybridized LDR-specific probes. In addition, a highly specific probe, MB, was used to detect the products of all-in-one approach, which doubly enhances the specificity of the all-in-one approach. The linear dynamic range and high sensitivity of mutant DNA (MutDNA) and wild-type DNA (WtDNA) all-in-one approaches for the detection of MutDNA and WtDNA were studied in vitro, with a broad linear dynamic range of 0.1 fM to 1 pM and detection limits of 65.3 aM and 31.2 aM, respectively. In addition, the MutDNA and WtDNA all-in-one approaches were able to accurately detect allele frequency changes as low as 0.1%. In particular, the epidermal growth factor receptor T790M MutDNA frequency in the tissue of five patients with non-small cell lung cancer detected by all-in-one approaches were in agreement with clinical detection results, indicating the excellent practicability of the developed approaches for the quantification of SNPs in real samples. In summary, the developed all-in-one approaches exhibited promising potential for further applications in clinical diagnosis.
