Associations of DR2 specificity of the DRB1 gene and single-nucleotide polymorphisms of the tumor necrosis factor gene TNFα (−308 G/A), interleukin genes IL-1β (−511 C/T), IL-2 (−475 A/T and −631 G/A), IL-6 (−634 C/G), paraoxanase gene PON1 (M55L, Q192R), and the mitochondrial protein transport gene UCP2 (−866 G/A) with the development of multiple sclerosis(More)
Some characteristic peculiarities of the 5'-end and 3'-end structures of pre-mRNA isolated from nuclear RNP particles have been investigated: presence of triphosphorylated nucleotides on the 5'-ends, as a characteristic of the primary product of transcription; presence of modified 5'-ends -- blocked and methylated structures -- caps; presence of poly(A)(More)
Complex formation between streptomycin sulfate and poly(acrylic acid) has been studied in aqueous solutions by turbidimetric, potentiometric and viscometric methods as well as by FTIR spectroscopy. It was shown that these polycomplexes are stabilized by electrostatic interactions. The solubility of polycomplexes was examined as a function of pH and it was(More)
Synthesis of p53 and WAF1 (p21) proteins was studied in cells of patients with Nijmegen breakage syndrome (NBS) and of patients with ataxia telangiectasia (AT), as well as in normal cells with respect to their response to ionizing radiation (IR). In the NBS cells, the p53 protein was progressively accumulated with increasing radiation dose and reached the(More)
Polymorphism of major noncoding region of mitochondrial DNA (mtDNA D-loop, 528 bp in length) from the three modem kazakh populations and from DNA samples of ancient people inhabited modern Kazakhstani Altai were studied. PCR and RFLP analysis of 13 sites of restriction--BamHI, EcoRV, Sau3AI (1 restriction site), KpnI (2 sites), HaeIII (3 sites), RsaI (5(More)
A search for association of polymorphisms in loci rs2981582, rs2420946, rs17102287, rs1219648, rs2981578, and rs17542768 in fibroblast growth factor receptor 2 (FGFR2) gene was performed using the “case-control” method among the major ethnic groups of Kazakhstan. Restriction fragments length polymorphism analysis of DNA obtained from 495 Kazakh and 195(More)
Polymorphism of the promoter region of the angiotensinogen gene (ATG) and an angiotensin I-converting enzyme gene (ACE) insertion/deletion (I/D) polymorphism were studied in three different groups of Kazakhs (control group, patients with cardiovascular disease (CAD) and patients with arterial hypertension (AH)) using three methods. A comparative analysis of(More)
