Figure 6. Effects of Nrf2 or (and) Rap1b knockdown on the regulation of the GC invasion capacity under a hypoxic condition. The invasion capacity was suppressed in GC cells transfected with siNrf2RNA-1498 or (and) siRap1bRNA-501 under hypoxic conditions. (A) Negative control; (B) siRap1bRNA; (C) siNrf2RNA; (D) siRap1bRNA and siNrf2RNA; (E) The graph shows the quantified data of the assay. (*P<0.05, **P<0.001).
