Figure 6. Knock down of S100P partially reverses TzR in cell culture.

Cell proliferation analysis using MTS colorimetric assay demonstrated that TzR BT474 cells treated with either mock vs trastuzumab (10 μg/ml) for 96 hours show decreased proliferation rate when S100P levels are depleted with two independent shRNAs targeting S100P vs a negative control shRNA targeting GFP.
