siRNA-mediated suppression of PC expression in MDA-MB-231 cell line.

<p>Real time PCR analysis of PC mRNA expression in MDA-MB-231 cells transfected with scrambled control (Control) or PC siRNA. The PC mRNA level was determined by Q-PCR at 48 h post-transfection (A). Western blot analysis of PC protein in the PC knockdown MDA-MB-231 and the scrambled control (B). The statistical analysis was conducted using student’s t-test ***<i>P</i> ≤ 0.001.
