PELP1 knockdown affects expression of selective genes involved in EMT. A, RNA isolated from MDA-MB231-siRNA negative control and MDA-MB231-PELP1siRNA-expressing cells was hybridized to the human EMT Array. Changes in the gene expression were analyzed by using SABioscience software with actin as a control for normalization. Representative genes downregulated upon PELP1 depletion are shown. B, Real-time qPCR validation of the changes in gene expression in MDA-MB231 cells stably expressing negative control shRNA or PELP1-shRNA. C, MDA-MB231 cells were transiently transfected with control or PELP1-specific siRNA and the expression of indicated genes was analyzed by real-time qPCR. *, p ≤ 0.05, t test.
