Identification of single nucleotide polymorphisms by a peptide nucleic acid-based sandwich hybridization assay coupled with toehold-mediated strand displacement reactions. Anal Chim Acta 2023; 1242:340810. [PMID: 36657895 DOI: 10.1016/j.aca.2023.340810] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 01/03/2023] [Accepted: 01/05/2023] [Indexed: 01/07/2023]
Abstract
In this work, we developed a simple and accurate peptide nucleic acid (PNA)-based sandwich hybridization assay for single nucleotide polymorphisms (SNPs) in the p53 gene. Our approach combines the enzyme-free toehold-mediated strand displacement reaction (SDR) with real-time enzyme-linked immunosorbent assay (ELISA) to detect SNPs with high sensitivity and specificity. A PNA-DNA heteroduplex with an external toehold is designed and fixed on well surface of a 96-well plate. The strand displacement from PNA-DNA heteroduplexes is initiated by the hybridization of target sequence with the toehold domain and ends with the fully displacing of the incumbent DNA. Finally, the as formed PNA-target DNA duplex with overhang at its 5'-end hybridizes with a biotin-labeled reporter PNA to form a sandwich structure on surface for signal amplification. The proposed PNA-based sandwich biosensor displays high sensitivity and greatly enhanced discriminability to target p53 gene segments against single-base mutant sequences compared to its all-DNA counterpart. Furthermore, the probe design is elegantly simple and the sensing procedure is easy to operate. We believe that this strategy may provide a simple and universal strategy for SNPs detection through easily altering the sequences of probes according to the sequences around target SNPs.

Towards the Development of a 3-D Biochip for the Detection of Hepatitis C Virus. SENSORS 2020; 20:s20092719. [PMID: 32397590 PMCID: PMC7249126 DOI: 10.3390/s20092719] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/06/2020] [Accepted: 05/06/2020] [Indexed: 02/06/2023]
Abstract
The early diagnostics of hepatitis C virus (HCV) infections is currently one of the most highly demanded medical tasks. This study is devoted to the development of biochips (microarrays) that can be applied for the detection of HCV. The analytical platforms of suggested devices were based on macroporous poly(glycidyl methacrylate-co-di(ethylene glycol) dimethacrylate) monolithic material. The biochips were obtained by the covalent immobilization of specific probes spotted onto the surface of macroporous monolithic platforms. Using the developed biochips, different variants of bioassay were investigated. This study was carried out using hepatitis C virus-mimetic particles (VMPs) representing polymer nanoparticles with a size close to HCV and bearing surface virus antigen (E2 protein). At the first step, the main parameters of bioassay were optimized. Additionally, the dissociation constants were calculated for the pairs “ligand–receptor” and “antigen–antibody” formed at the surface of biochips. As a result of this study, the analysis of VMPs in model buffer solution and human blood plasma was carried out in a format of direct and “sandwich” approaches. It was found that bioassay efficacy appeared to be similar for both the model medium and real biological fluid. Finally, limit of detection (LOD), limit of quantification (LOQ), spot-to-spot and biochip-to-biochip reproducibility for the developed systems were evaluated.

Abstract
Screening epidermal growth factor receptor (EGFR) mutations, especially deletions, is essential for diagnosis of non-small cell lung cancer (NSCLC) and also critical to inform treatment decisions for NSCLC patients. Here, we demonstrated a facile peptide nucleic acid (PNA) microarray-based fluorometric method for sensitive and specific detection of EGFR mutation, using rolling circle amplification (RCA), graphene oxide (GO), and a fluorescently-labeled detection probe (F-DP). First, the EGFR gene sequence was efficiently captured by the label-free PNA probe which was attached on the surface of a 96-well plate. And then, the EGFR mutation sequence was specifically amplified by RCA using the circular DNA, which was formed by the ligation of the padlock probe when hybridizing with the EGFR mutation, as a template. The single-stranded RCA product (RCAP) was then sensitively detected with the F-DP and GO system. This method has a detection limit of 0.3 pM for EGFR mutation and a high discrimination capability to target EGFR mutation against EGFR wildtype. The use of a PNA microarray and a fluorescence quenching platform make this system quite suitable for high-throughput analysis of EGFR mutations in resource-limited settings without the need of costly and cumbersome equipment. Furthermore, this detection system provides a novel way for the diagnosis of other diseases that are caused by gene deletion mutations.

Abstract
Peptide nucleic acid (PNA) is a mimic of DNA that shows a high chemical stability and can survive the enzymatic degradation of nucleases and proteases. The superior binding properties of PNA enable the formation of PNA/DNA or PNA/RNA duplex with excellent thermal stability and unique ionic strength effect. The introduction of microarray makes it possible to achieve accurate, high throughput parallel analysis of DNA or RNA with a highly integrated and low reagents consuming device. This powerful tool expands the applications of PNA in genotyping based on single nucleotide polymorphism (SNP) detection, the monitoring of disease-related miRNA expression and pathogen detection. This review paper discusses the fabrications of PNA microarrays through in situ synthesis strategy or spotting method by automatic devices, the various detection methods for the microarray-based hybridization and the current applications of PNA microarrays.

Abstract
Sequence-specific detection of double stranded DNA (dsDNA) is important in various research fields. In general, denaturation of dsDNA into single strands is necessary for the sequence-specific recognition of probes to target DNA, posing several drawbacks which decrease the efficiency as a DNA sensor. Herein, we report a direct, sequence-specific dsDNA detection system without requiring any thermal denaturing step. Our strategy utilizes peptide nucleic acid (PNA) and graphene oxide (GO) as a probe and as a fluorescence quencher, respectively. The PNA first binds to the end of dsDNA strand due to the relatively easily dissociable terminal base pairs of DNA duplex. Next, superior binding affinity of PNA towards complementary DNA induces branch migration for gradual strand replacement, resulting in the formation of PNA/DNA duplex. Unlike other dsDNA sensors based on complementary DNA probes, PNA in combination with GO enabled hybridization with the target sequence hidden as a duplex form without denaturing step and thus, the formation of PNA/DNA duplex was translated into selective fluorescence signal. Moreover, it provided tighter turn-on signal control with very low background signal and high sensitivity and sequence selectivity even in the presence of serum proteins.

Abstract
Peptide nucleic acids (PNAs) have gained much interest as molecular recognition tools in biology, medicine and chemistry. This is due to high hybridization efficiency to complimentary oligonucleotides and stability of the duplexes with RNA or DNA. We have synthesized 15/16-mer PNA probes to detect the HER2 mRNA. The performance of these probes to detect the HER2 target was evaluated by fluorescence imaging and fluorescence bead assays. The PNA probes have sufficiently discriminated between the wild type HER2 target and the mutant target with single base mismatches. Furthermore, the probes exhibited excellent linear concentration dependence between 0.4 to 400 fmol for the target gene. The results demonstrate potential application of PNAs as diagnostic probes with high specificity for quantitative measurements of amplifications or over-expressions of oncogenes.

Abstract
Nucleic acid biosensors have a growing number of applications in genetics and biomedicine. This contribution is a critical review of the current state of the art concerning the use of nucleic acid analogues, in particular peptide nucleic acids (PNA) and locked nucleic acids (LNA), for the development of high-performance affinity biosensors. Both PNA and LNA have outstanding affinity for natural nucleic acids, and the destabilizing effect of base mismatches in PNA- or LNA-containing heterodimers is much higher than in double-stranded DNA or RNA. Therefore, PNA- and LNA-based biosensors have unprecedented sensitivity and specificity, with special applicability in DNA genotyping. Herein, the most relevant PNA- and LNA-based biosensors are presented, and their advantages and their current limitations are discussed. Some of the reviewed technology, while promising, still needs to bridge the gap between experimental status and the harder reality of biotechnological or biomedical applications.

Abstract
A major problem of long-term antiviral therapy in chronic hepatitis B patients is the emergence of hepatitis B virus (HBV) mutations associated with drug resistance. Recently, a new array using peptide nucleic acids (PNAs), which are synthetic nucleic acid analogues, was developed for the detection of HBV mutations at six different codon positions associated with lamivudine (LAM) and adefovir (ADV) resistance. We compared the PNA array with direct sequencing and reverse hybridization (INNO-LiPA) in 73 samples obtained from chronic hepatitis B patients. The PNA array detected mutations associated with LAM and/or ADV resistance in 60 (82.2%) of the 73 samples. The overall concordance rate of PNA array and INNO-LiPA compared with direct sequencing was 99.5% and 98.2%, respectively. The rate of complete concordance between PNA array and INNO-LiPA was 92.7%. The PNA array assay results were comparable with INNO-LiPA for detection of HBV mutations associated with antiviral resistance.
