The effect of HuR silencing on the protein expression levels of survival signaling-, efflux transporter- and apoptosis-related factors in colon cancer cells by western blotting.

<p>Cells were transfected with 75 nM siC or siHuR. After 24 h, cells were treated with Epi (5 μg/ml) for 24 h and then harvested. The expression levels of proteins, including galectin-3, c-Myc, P-gp, MRP1, Bcl-2, caspase-3, -9 and β-actin were examined by western blotting (N = 3). The representative result is shown.
