Current research interests

Our current research is focusing on the investigation of functional compartmentalization and 3D-architecture of the oocyte nucleus (germinal vesicle). Nowadays, the role of intranuclear actin in the regulation of transcription and spatial genome organization in amphibian and avian growing oocytes has been studied in details. Molecular composition and 3-dimentional organization of meiotic chromosomes and intranuclear domains, such as amplified nucleoli and Cajal bodies, have been investigated by using of microinjections of fluorescently labeled molecules, modern techniques of confocal laser scanning microscopy and computational image-processing procedures, such as iso-surfacing and building the 3D-reconstructions. We also pay a special attention to establishment a link between the formation of various intranuclear domains and the expression of long non-coding RNA molecules. Giant lampbrush chromosomes from growing oocytes are been using as an adequate tool for exploration of genome expression. Fate and functions of non-coding RNA transcripts accumulating during the lampbrush stage of oogenesis are also under our investigation.
