Figure 11

Effect of atRA on growth of trastuzumab-resistant BT474 cells. WST-1 proliferation assay of trastuzumab-resistant BT474 cells treated for 6 days with 10 μM GW2974, 1 μM all-trans retinoic acid (atRA), or their combination, in the presence or absence of trastuzumab (Tzmab) in the culture media. Each bar is normalized to the growth of control (C, vehicle-treated) cells in trastuzumab-containing media. Each value is the mean of three independent experiments (with three replicate wells for each treatment) ± standard error.
