Main research interests

2005-2016
The main research field is a process of germinal tissue development on the Drosophila model, including a study of the mechanisms of germline stem cells maintenance and self-renewal. A mapping of the promoter of the tandem testis-specific Stellate genes was performed and cis-regulatory regions (E-boxes) was identified. Stellate protein was found in a soluble form of the protein in the nucleoplasm and was found that it contained lysine trimethylation mark. A large nuage-associated organelle in the testes, (piRNA nuage giant body) was discovered in primary spermatocytes. The piNG-body is responsible for compartmentalization of piRNA pathway components and for post-transcriptional piRNA-mediated silencing of stellate genes in the testes. The molecular functions of germinal RNA helicases (Vasa, Belle and Spn-E) that are essential for the process of oogenesis and spermatogenesis, are investigated. It is shown that RNA helicase Belle (DDX3) is essential intrinsically for germline stem cell maintenance and division in the testes.
