Effects of PDCD4 on MHCC-97H cell metastatic potential. B: Western blots for MTA1 expression. A and C: Statistical analysis for MTA1 expression with real-time PCR and western blot assay, respectively. D: Cell migration assay. E: Matrigel invasion assay. Representative images are shown from three individual experiments. In A, C, D and E, a or Group1, b or Group 2, and c or Group3 represents cells of MHCC-97H-PDCD4, MHCC-97H-vector and MHCC-97H, respectively. Bars represent the means ± SD. Difference between Group1 and Group2 or Group1 and Group3 was significant (P < 0.05 in A and C; P < 0.01 in D and E).
