Research focus

  • Elaboration of new methods of gene expression regulation and novel therapeutic agents on the base of the oligonucleotides and their derivatives.
  • Investigation of ways of the genetic material delivery into cells.
  • Creation and study of artificial ribonucleases.

Main scientific results

  • Mechanism of hybridization of antisense oligonucleotides with RNA was defined. It was shown that antisense oligonucleotide hybridization with RNA as a target was a multistep process initiated by an intermediate oligonucleotide complex formation between oligonucleotide and partially complementary sequence localized in the loop or single-stranded region of RNA. [Serikov R. et al., J. Biomol. Strt. Dyn., 2011. 29(1), 27].
  • A new class of conjugates of short oligonucleotides with [ArgLeu]4 peptide capable of cleaving the RNA phosphodiester bonds at GpX motives was synthetized. Such specificity was for the first time revealed for artificial ribonucleases. It was shown that the catalyst active conformation was formed due to specific interaction of peptide with oligonucleotide. These elaborated catalysts are interesting as tools for the study of RNA and RNA-protein complexes structure. [Mironova N.L. et al., Nucleic Acids Res. 2007. 35, 2356; Mironova N.L. et al., J. Biomol. Strt. Dyn. 2006. 23, 591].
  • Formation of new molecules of RNA in the cleavage/ligation coupled reaction proceeding in the complex of partially complementary oligoribonucleotides in the presence of magnesium ions was shown for the first time. This reaction could proceed in the prebiotic conditions of RNA world providing both elongation of molecules and appearance of novel sequences. [Nechaev S.V. et al., Int. J. Molecular Sci. 2009. 10, 1788; Lutay A.V. et al., In book: Origin of life. Chemical Approach. 2008, 323; Lutay, A.V. et al., Chem. & Biodivers. 2007. 4, 762; Lutay A.V. et al., Biogeosciences. 2006. 3, 243].
  • Series of novel low-molecular weight compounds capable of efficient cleavage of phosphodiester bonds within RNA were designed. The compounds - so called artificial ribonucleases (aRNases) - were shown to cleave RNA with specificity of RNase A. Designed aRNases display antiviral activity in respect to RNA containing viruses and can be applied for preparation of candidate vaccines. [Tamkovich N.V. et al., Bioorg. Chem. 2010. 36, 223; Kovalev N. et al., Bioorganic Chem. 2008 36, 33; Kovalev N. et al., Bioorg. Chem. 2006. 34, 274; Goncharova E.P. et al., Dokl. A.N. 2009. 427, 840].
  • Based on the data of degradation of small interfering RNAs (siRNAs) and their modified analogs in the presence of serum the algorithm of addressed chemical modification of siRNA was created, which allows to prepare nuclease resistant siRNA analogs bearing minimal number of modifications. These siRNAs analogs provide a record of 12–15 days gene silencing after a single application. [Chernolovskaya E.L. et al., Curr. Opin. Mol. Ther. 2010. 12, 158; Kruglova N.S. et al., Mol Biol. 2010. 44, 284; Spirin P.V. et al., Mol Biol. 2010. 44, 876].
  • Small interfering RNAs (siRNAs), targeted to mRNA of C- and N-MYC genes capable of effective gene silencing were developed. These siRNAs induce 10-15 fold retardation of human neuroblastoma cells proliferation. Prolonged inhibition of C-MYC gene expression gives opportunity to use the potential of siRNA (siRNA-I) to create drugs for cancer therapy. [Akimov I.A. et al., Mol Biol. 2010. 44, 98; Akimov I.A. et al., Oligonucleotides. 2009. 19, 31; Kabilova T.O. et al., Oligonucleotides. 2006. 16, 15; Kabilova Т.О. et al., Mol Biol. 2006. 40, 1037; Kabilova Т.О. et al., Ann. N.Y. Acad. Sci. 2006. 1091, 425].
  • Nuclease resistant siRNAs, targeted different regions of MDR1 mRNA, which efficiently reverse multiple drug resistance phenotype of tumor cells and 10-times increase their sensitivity to cytostatic agents were developed. Combined therapy of tumor with multidrug resistance phenotype based on siRNA, targeted MDR1 gene, and pro-apoptotic cytostatic cyclophosphamide were applied to the model of tumor progression in vivo. Single administration of the developed siRNA increases the effectiveness of chemotherapy twice. [Patutina O.A. et al., BMC Cancer. 2010. 10, 1; Volkov A.A. et al., Oligonucleotides. 2009. 19, 191; Logashenko E.B. et al., RUSS CHEM B. 2006. 7, 1227].
  • Using two murine tumor models with pulmonary or liver metastases allowed to show the antimetastatic potential of RNase A and DNase I for the first time. Daily administration of ultralow doses of RNase A and DNase I inhibits the development of metastasis to 60 – 90 % and exerts retardation of tumor growth. Simultaneous treatment of tumor-bearing animals with RNase A and DNase I leads to an additive effect and results in almost total absence of metastases. The search for possible molecular mechanism of antimetastatic effect of nucleases showed that the enzymes restored pathologically increased level of extracellular nucleic acids and reduced nuclease activity of the blood plasma of tumor-bearing mice in comparison with the level of healthy animals. [Patutina O.A. et al., Acta Naturae. 2010. 2, 95; Patutina O.A. et al., Acta Naturae. 2009. 2, 47; Shkliaeva (Patutina) O.A. et al., Dokl Biochem Biophys. 2008. 420, 134; Mironova N.L. et al., Ann. N.Y. Acad. Sci. 2006. 1091, 490].
