Figure S1. RNAi transfection decreases PLK1 mRNA and protein levels in medulloblastoma cell lines. Quantifying bar graphs depicting significant decreases in PLK1 mRNA levels in Daoy medulloblastoma cell line transfected: (A) with either a non-targeting shRNA (shNTC) or two different shRNAs targeting PLK1 (shPLK1 1073 and shPLK1 1325), (B) with either a scrambled siRNA (siRNA N.C.) or three different siRNAs targeting PLK1 (siPLK1-A, siPLK1-B, and siPLK1-C). Error bars represent SEM. (C) ONS-76 cells show a significant decrease in PLK1 mRNA expression following transfection with siPLK1-A. Error bars represent SEM. (B) Western blot analysis confirms that RNAi-mediated knockdown of PLK1 decreases the level of PLK1 protein in both Daoy and ONS-76 cells.
