(b) Doxycycline-inducible RAB2A-shRNA MDA-MB-231 cells were cultured in the absence (CTR) or presence (shRAB2A) of doxycycline for three days. Invasion of MDA-MB-231 cells through Matrigel-coated transwells toward HGF was assessed after 24 hours. Representative images are shown. Data are the mean ± SD (n=10 field/condition in at least 3 experiments). Bar, 200 µm.
