Additional file 7: of Isocitrate dehydrogenase 1–snail axis dysfunction significantly correlates with breast cancer prognosis and regulates cell invasion ability

Figure S3. IDH1 stable knockdown significantly promoted MDA-MB-231 cell motility. (a) The expression levels of IDH1 were examined in two IDH1 stable knockdown MDA-MB-231 cells (shIDH1#1 and shIDH1#2) through western blotting. (b) Invasion ability was assessed using the Transwell assay in MDA-MB-231 cells with IDH1 stable knockdown and a scrambled control. The cell images of the representative experiment are provided. (c) Values were quantified using Ascent software, as detailed. Data are reported as the number of invading cells relative to the control (means Âą standard deviation (SD)). (d) Expression levels of IDH1, snail, slug, twist, and actin were examined in shIDH1#1, shIDH1#2, and the scrambled control through western blotting. (TIFF 3572 kb
