Аннотация: Aim: To develop magnetic nanoparticles (MNPs) based on iron oxide for DNA isolation from blood cells for quantitative molecular genetic analyses of the V617F mutation in the Januskinase 2 (JAK2) gene. Materials and Methods: MNPs were synthesized by the coprecipitation method and coated with tetraethyl orthosilicate (TEOS). The size and shape of the complexes were estimated using transmission electron microscopy. Twenty blood samples from patients with myeloproliferative disorders were used for DNA isolation with the MNPs. DNA quality and compatibility for molecular genetic studies of the JAK2 V617F mutation were investigated by gel electrophoresis and real-time polymerase chain reaction (RT-PCR). Results: The average amount of DNA isolated from 150 μL of whole blood was 75.2 ng when MNPs were used and 72.5 ng when standard silica sorbent was used. There was no DNA damage observed after interaction with MNPs. RT-PCR demonstrated similar values for the JAK2 V617F mutant DNA ratios in the samples after DNA isolation with MNPs and by standard sorption on silica. Conclusions: MNPs with silicate capsules of sufficient thickness were obtained and the undesirable damaging effect of iron oxides on nucleic acids during isolation from cells were eliminated. Designed MNPs allow obtaining intact DNA for molecular genetic studies using the example of the JAK2 V617F for study.

aptamer -- oligonucleotide -- tertiary structure -- spatial structure -- lung adenocarcinoma -- small-angle X-ray scattering -- SAXS -- molecular dynamics -- fragment molecular orbital -- molecular simulations
Аннотация: Aptamers are short, single-stranded DNA or RNA oligonucleotide molecules that function as synthetic analogs of antibodies and bind to a target molecule with high specificity. Aptamer affinity entirely depends on its tertiary structure and charge distribution. Therefore, length and structure optimization are essential for increasing aptamer specificity and affinity. Here, we present a general optimization procedure for finding the most populated atomistic structures of DNA aptamers. Based on the existed aptamer LC-18 for lung adenocarcinoma, a new truncated LC-18 (LC-18t) aptamer LC-18t was developed. A three-dimensional (3D) shape of LC-18t was reported based on small-angle X-ray scattering (SAXS) experiments and molecular modeling by fragment molecular orbital or molecular dynamic methods. Molecular simulations revealed an ensemble of possible aptamer conformations in solution that were in close agreement with measured SAXS data. The aptamer LC-18t had stronger binding to cancerous cells in lung tumor tissues and shared the binding site with the original larger aptamer. The suggested approach reveals 3D shapes of aptamers and helps in designing better affinity probes.

Аннотация: The high potential of aptamers – specific molecular agents based on short single-stranded nucleic acids – makes high demands on the molecules under development for the efficiency of interaction with target biomolecules. In this work, approaches are considered for studying the spatial structure of DNA aptamers in solution using various complementary methods, which make it possible to obtain a more complete picture of the formation of the structure and conformational changes, to track the interaction with the target protein, the tendency to oligomerization, and to characterize the spatial structure of both individual molecules and complexes.

LC-18 -- DNA aptamer -- lung adenocarcinoma -- SAXS -- DFTB3
Аннотация: The aim of the research. In this work we studied the structure of LC-18 DNA aptamer, which exhibits specific binding to lung adenocarcinoma cells. Obtain-ing the 3D structure of the aptamer is necessary for understanding the mechanism of binding of the aptamer to the target. Therefore, the aim of the research was modeling of the LC-18 aptamer spatial structure using combination of theoretical methods: DNA folding tools, quantum-chemical calculations and molecular dynamic simulations. Material and methods. The secondary structure of the LC-18 aptamer was predicted by using OligoAnalyzer and MFold online software under the conditions typical small-angle X-ray scattering (SAXS) experiment. The molecular modeling of the aptamer was carried out using the Avogadro program. For prediction of the structure two computational methods were used: quantum-mechanical method with third-order density-functional tight-binding (DFTB3) and molecular dynamics (MD) with force fields. Results. In this paper it was shown that molecular simulations can predict structures from the SAXS experiments. OligoAnalyzer and MFold web servers have been used to generate a set of several likely models. However, more accurate calculations have showed that these models do not predict the relative importance of isomers. Meanwhile, application of quantum-chemical and molecular dynamics calculations have showed reliable molecular structures which have a small deviations from the experimental SAXS curves. Conclusion. This study demonstrates the approach for modeling 3D structures of DNA-aptamers in solution using both experimental and theoretical meth-ods. It could be very helpful in designing more efficient aptamers based on results obtained from molecular simulations.

MT: Oligonucleotides: Diagnostics and Biosensors -- COVID-19 diagnosis -- SARS-CoV-2 nucleocapsid detection -- label-free optical aptasensor -- aptamer selection -- biolayer interferometry -- binding motif identification
Аннотация: The spread of COVID-19 has affected billions of people across the globe, and the diagnosis of viral infection still needs improvement. Because of high immunogenicity and abundant expression during viral infection, SARS-CoV-2 nucleocapsid (N) protein could be an important diagnostic marker. This study aimed to develop a label-free optical aptasensor fabricated with a novel single-stranded DNA aptamer to detect the N protein. The N-binding aptamers selected using asymmetric-emulsion PCR-SELEX and their binding affinity and cross-reactivity were characterized by biolayer interferometry. The tNSP3 aptamer (44 nt) was identified to bind the N protein of wild type and Delta and Omicron variants with high affinity (KD in the range of 0.6–3.5 nM). Utilizing tNSP3 to detect the N protein spiked in human saliva evinced the potential of this aptamer with a limit of detection of 4.5 nM. Mass spectrometry analysis was performed along with molecular dynamics simulation to obtain an insight into how tNSP3 binds to the N protein. The identified epitope peptides are localized within the RNA-binding domain and C terminus of the N protein. Hence, we confirmed the performance of this aptamer as an analytical tool for COVID-19 diagnosis.

Аннотация: One of the promising novel methods for radical tumor resection at a single-cell level is magneto-mechanical microsurgery (MMM) with magnetic nano- or microdisks modified with cancer-recognizing molecules. A low-frequency alternating magnetic field (AMF) remotely drives and controls the procedure. Here, we present characterization and application of magnetic nanodisks (MNDs) as a surgical instrument (“smart nanoscalpel”) at a single-cell level. MNDs with a quasi-dipole three-layer structure (Au/Ni/Au) and DNA aptamer AS42 (AS42-MNDs) on the surface converted magnetic moment into mechanical and destroyed tumor cells. The effectiveness of MMM was analyzed on Ehrlich ascites carcinoma (EAC) cells in vitro and in vivo using sine and square-shaped AMF with frequencies from 1 to 50 Hz with 0.1 to 1 duty-cycle parameters. MMM with the “Nanoscalpel” in a sine-shaped 20 Hz AMF, a rectangular-shaped 10 Hz AMF, and a 0.5 duty cycle was the most effective. A sine-shaped field caused apoptosis, whereas a rectangular-shaped field caused necrosis. Four sessions of MMM with AS42-MNDs significantly reduced the number of cells in the tumor. In contrast, ascites tumors continued to grow in groups of mice and mice treated with MNDs with nonspecific oligonucleotide NO-MND. Thus, applying a “smart nanoscalpel” is practical for the microsurgery of malignant neoplasms.

Аннотация: Here, we present DNA aptamers capable of specific binding to glial tumor cells in vitro, ex vivo, and in vivo for visualization diagnostics of central nervous system tumors. We selected the aptamers binding specifically to the postoperative human glial primary tumors and not to the healthy brain cells and meningioma, using a modified process of systematic evolution of ligands by exponential enrichment to cells; sequenced and analyzed ssDNA pools using bioinformatic tools and identified the best aptamers by their binding abilities; determined three-dimensional structures of lead aptamers (Gli-55 and Gli-233) with small-angle X-ray scattering and molecular modeling; isolated and identified molecular target proteins of the aptamers by mass spectrometry; the potential binding sites of Gli-233 to the target protein and the role of post-translational modifications were verified by molecular dynamics simulations. The anti-glioma aptamers Gli-233 and Gli-55 were used to detect circulating tumor cells in liquid biopsies. These aptamers were used for in situ, ex vivo tissue staining, histopathological analyses, and fluorescence-guided tumor and PET/CT tumor visualization in mice with xenotransplanted human astrocytoma. The aptamers did not show in vivo toxicity in the preclinical animal study. This study demonstrates the potential applications of aptamers for precise diagnostics and fluorescence-guided surgery of brain tumors.
