The Expression Level of S100A4 Protein Affects the Migration Activity of Breast Cancer Cells

Reduced expression of metastatic marker protein S100A4 in triple-negative breast cancer cells MDA-MB-231 leads to a decrease in the migration ability of cells and increases the sensitivity of the modified cells to docetaxel therapy. Cells capable of migration differ from the immotile cells in the content of the S100A4 protein in the cell, and this difference persists after the treatment of cells with the agents that reduce the intracellular level of S100A4. The presence of exogenous S100A4 protein in culture medium reduces the content of this protein in breast cancer cells. The results of the study show that the ability of breast cancer cells to migrate depends on the S100A4 protein concentration in the cell.
