Figure 4. Q15 repressed the transcription of c-Myc.

(A) HeLa cells were treated with 0 or 5 µM Q15 for 24 h. The total RNA was extracted from the cells and used as a template for RT-PCR using primers specific for GAPDH or c-Myc. (B) HeLa cells were treated with 0−50 µM Q15 for 24 h. The whole cell lysates were analysed by western blotting with an antibodies against PARP, c-Myc or β-actin.
