Short description of ongoing research projects

Design and synthesis of RNA ligands targeting oncogenic miRNAs precursors specifically. Study of the inhibition of Drosha and Dicer cleavage of these precursors by the synthesized molecules and of the interactions between ligands and miRNAs precursors responsible for the inhibition effect.
