At 24 hours after transfection of indicated siRNA, HBC4 cells were treated with 2 μg/ml ADR for 2 hours. Forty-eight hours after treatment, the mRNA expression level of the indicated genes was determined using qPCR, and the log2-fold change of mRNA expression against the control condition (Mock, no ADR treatment) was calculated using the ΔΔCt method. The data are presented as the mean±SD from three independent experiments. The red dotted line shows the cutoff value. **P < 0.01, ***P < 0.001, N.S., not statistically significant. Representative data (9 genes) are presented. Additional data are shown in Supplementary Figure S6.
