[Retracted] Downregulation of MDR1 Gene by Cepharanthine Hydrochloride Is Related to the Activation of c-Jun/JNK in K562/ADR Cells
Figure 3
Effects of the JNK inhibitor SP600125 on CH-induced downregulation of MDR1 mRNA expression by RT-PCR analysis in K562/ADR cells (1 × 106). CH-induced downregulation of MDR1 mRNA expression was abolished partly when combined with SP600125 (2.0 μM).
