NSBP1 knockdown inhibits the invasion of ccRCC cells. (A), Representative photos showing the invasion of ccRCC cells into the lower chamber of transwell. ×200. (B), Gelatin zymography assay showing that MMP-9 and MMP-2 activities were decreased in NSBP1 knockdown 786-O cells. Data shown were mean ± SEM from three independent experiments. (C), Western blot analysis showing that the expression of VEGF, VEGFR-2, MMP-2, MMP-9, c-fos and c-jun were significantly decreased in NSBP1 knockdown 786-O cells. Data shown were mean ± SEM from three independent experiments. *p < 0.05, **p < 0.01, versus the scramble siRNA transfected control group.
