Fig. 4.

The change in transcript expression levels of genes in the a death receptor group (apoptosis regulating) and b cell cycle regulating genes (transcription factors important for the cell cycle). BT-474 cells were cultured for 72 h in CM with the addition of DMSO only (Control) or 30 μg/ml cardanol or 0.5 μg/ml doxorubicin. Data are shown as the mean ± 1 SD, derived from three independent repeats. Significant difference between the control and treated cells are shown at the (**) p < 0.01 and (*) p < 0.05 levels
