The interaction of the 16-mer synthetic peptide (Aβ16), which represents the metal-binding domain of the amyloid-β with DNA, was studied employing the surface plasmon resonance technique. It has been shown that Aβ16 binds to the duplex DNA in the presence of zinc ions and thus the metal-binding domain can serve as a zinc-dependent DNA-binding site of the(More)
Interaction of intranuclear β-amyloid with DNA is considered to be a plausible mechanism of Alzheimer’s disease pathogenesis. The interaction of single- and double-stranded DNA with synthetic peptides was analyzed using surface plasmon resonance. The peptides represent the metal-binding domain of β-amyloid (amino acids 1–16) and its variants with chemical(More)
Alzheimer's disease is the most prevalent neurodegenerative pathology. According to the amyloid cascade hypothesis, a key event of the Alzheimer's disease pathogenesis is a transition of the β-amyloid peptide (Аβ) from the monomeric form to the aggregated state. The mechanism of Аβ aggregation is intensively studied in vitro, by means of synthetic peptides(More)
A novel electrochemical method for the detection of bioaffinity interactions based on a gold-nanoparticles sensing platform and on the usage of stripping voltammetry technique was developed. The oxidation of gold surface (resulted in gold oxide formation) upon polarization served as a basis for analytical response. As a model, thrombin-thrombin binding(More)
Using two DNA aptamers selectively recognizing anion-binding exosites 1 and 2 of thrombin as a model, it has been demonstrated that their conjugation by a poly-(dT)-linker (ranging from 5 to 65 nt in length) to produce aptamer heterodimeric constructs results into affinity enhancement. The apparent dissociation constant (Kd(app)) measured at the optical(More)
In order to investigate whether single nucleotide polymorphisms G(+2722)C and 3020insC in CARD15 gene and Asp299Gly in TLR4 gene contribute to atopic bronchial asthma we performed a comparative analysis of alleles and genotypes frequencies of these polymorphisms in Russian patients from Moscow. DNA samples from 283 patients with atopic bronchial asthma and(More)
A comparative analysis of allele and genotype distribution of C(-1055)T and R130Q IL13 gene polymorphisms has been performed in Russian patients from the Moscow region. In the study, 283 DNA specimens of atopic bronchial asthma (BA) patients and 227 DNA specimens of healthy donors were used. No association of these markers with ABA development as well as(More)
Recent achievements in the whole-genome sequencing especially viral and bacterial ones, together with the development of methods of bioinformatics and molecular biology, have created preconditions for transition from synthesis of genes to assembly of the whole genomes from chemically synthesized blocks, oligonucleotides. The creation of artificial genomes(More)
Single nucleotide polymorphisms (SNPs) are now considered as the most perspective and convenient markers for research of genetic bases of multifactorial diseases. Fast development of technologies for exact screening of great volume of genetic information, construction of genomic maps of SNP-markers promotes development of innovative diagnostic systems on(More)
OBJECTIVE The programmed death-1 receptor, PD-1, is a negative regulator of T-cell activation. The PD-1.3 polymorphism of the PD-1 gene (PDCD1) has been previously shown to be associated with several autoimmune and inflammatory disorders including systemic lupus erythematosus and multiple sclerosis. We examined for the first time PD-1.3 association with(More)
