Effect of extracellular S100A4 on melanoma cells of different phenotypes

ABSTRACT: S100A4 is a known metastasis-promoting factor, rich in the tumor microenvironment. To clarify how extracellular S100A4 execute its pro-metastatic function, we analyzed gene expression in melanoma cells stimulated with recombinant protein rS100A4 and compared it to the expression in control non-stimulated cells. Two melanoma cell lines representing two distinct phenotypes – invasive (Melmet 1) and non-invasive/proliferative (Melmet 5) – were included in the study. The response at the gene expression level was much stronger in Melmet 5 than in Melmet 1. Melmet 5 down-regulated genes associated with melanocytic differentiation, indicating that Melmet 5 cells gained dedifferentiated, more invasive phenotype after stimulation with rS100A4. The observed changes in the expression of metabolism as
