Main directions of research

Studies of gene expression regulation using Drosophila melanogaster as a model:
  1. Studies of small piRNAs in transposon repression.
  2. Investigation of the role of the microenvironment of somatic cells in the differentiation of germ cells.
  3. Analysis of cis and trans-effects of heterochromatin on target genes. 
  4. Studies of functional role of testis specific NAC protein associated to ribosomes. 
   
   

Main scientific results

A new class of small RNAs was discovered, subsequently termed piRNAs, and for the first time the role of RNAi in gene expression regulation in vivo without the use of artificial genetic constructs was demonstrated (2001).
The function of RNAi in telomere length maintenance in Drosophila and the role of a protein of the Agronaute family in the suppression of transposition was demonstrated (2005, 2006).
The repression of transposons at the level of transcription, carried out by piRNA pathways proteins was revealed (2007, 2011, 2014).
A new organelle was described – a large perinuclear granule containing piRNA pathways proteins (2009).
The role of nuclear Piwi localization in transposon repression was shown (2011).
Piwi was revealed in the nuclei of somatic and germline gonadal cells (2015).
New genes were discovered which are expressed specifically in testis germline cells and code for a subunit of the translation complex bound to the ribosome. Their amplification in the evolution of the species was traced (2005, 2012).
It was shown that Belle RNA helicase, homologous to human DBY protein the lack of which causes male sterility (Sertoli cell-only syndrome), is indispensable as a cell-autonomous factor for germline cell development and as a regulatory protein in the surrounding somatic niche cells, ensuring differentiation of germline cells and preventing their uncontrolled division accompanied by tumor-like structure formation (2016).
