Research in the field of molecular oncology concerns the development of new therapeutic strategies based on the regulation of gene expression with the use of non-coding RNA molecules (ncRNA). The aim of the research is to characterize the molecular phenotype of bone cancer (osteosarcoma) and liposarcoma (liposarcoma).

These studies are carried out on the basis of molecular biology techniques, including the use of high-pass RTq-qPCR tests (transcriptome analysis) or protein expression analysis (proteome analysis). Additionally, the molecular phenotype of neoplastic cells is assessed using flow cytometry and immunocytochemistry.
