Metastasis causes death of 90% of cancer patients, so it is the most significant
issue associated with cancer disease. Thus, it is no surprise that many
researchers are trying to develop drugs targeting or preventing them. The
secondary tumour site formation is closely related to phenomena like
epithelial-to-mesenchymal and its reverse, mesenchymal-to-epithelial transition.
The change of the cells' phenotype to mesenchymal involves the acquisition of
migratory potential. Cancer cells movement is possible due to the development of
invasive structures like invadopodia, lamellipodia, and filopodia. These changes
are dependent on the reorganization of the actin cytoskeleton. In turn, the
polymerization and depolymerization of actin are controlled by actin-binding
proteins. In many tumour cells, the actin and actin-associated proteins are
accumulated in the cell nucleus, suggesting that it may also affect the
progression of cancer by regulating gene expression. Once the cancer cell reaches
a new habitat it again acquires epithelial features and thus proliferative
activity. Targeting of epithelial-to-mesenchymal or/and mesenchymal-to-epithelial
transitions through regulation of their main components expression may be a
potential solution to the problem of metastasis. This work focuses on the role of
these processes in tumour progression and the assessment of therapeutic potential
of agents targeting them.
