Fig. 5. S100A9 suppresses the migration and invasion of PCa cells, and overexpression of S100A9 rescues this effect after knockdown of circ_0006156.
A–D qRT–PCR and western blot analyses of the inhibition and overexpression efficiency of S100A9 in PCa cells. E, F Transwell assays showed that S100A9 suppressed the migration and invasion of PCa cells. G, H Wound-healing assays showed that S100A9 weakened the migration of PCa cells. I, J Transwell and wound-healing assays showed that the migration and invasion abilities enhanced by knocking down circ_0006156 were partially inhibited by overexpressing S100A9.
