Research area


  • Structural and functional analysis of sequence variants of the 5' non-coding region of p53 mRNA: characterization of the structure of this region and its role in the translation process; elucidating the role of different p53 protein isoforms synthesized in the cell; identification and characterization of proteins interacting with the 5' non-coding region of p53 mRNA.

  • Coxsackie B3 virus research: searching for highly conserved RNA structural elements in the CVB3 virus genome and their structural and functional analysis; development of a rational strategy for attacking viral RNA using oligonucleotide tools; virus-cell interactions.

  • Application of embryonic and mature kidney cells as a model of cultured human stem cells to understand the different stages of development of this organ: analysis of the expression of non-coding RNAs using new sequencing methods; characterization of the interaction of various molecules with long non-coding RNAs in human cells.
