Effects of FosB knock down on cell invasion. PC3 cells were pretreated with siRNA against FosB, followed by treatment with 10 ng/ml of exogenous TGF-β1 and 10 ng/ml EGF. Invasive behavior was measured using a matrigel in vitro invasion assay. Insert shows western blot used to confirm FosB knock down. Each bar represents Mean ± SEM from three independent experiments. Different letters designate statistically significant (P < 0.05) differences among different treatments.
