[Retracted] Downregulation of MDR1 Gene by Cepharanthine Hydrochloride Is Related to the Activation of c-Jun/JNK in K562/ADR Cells

Figure 2

Effects of CH on MDR1 mRNA and P-gp expression in K562/ADR cells. RT-PCR and Western blot analyses were performed to analyze MDR1 mRNA and P-gp expression in K562/ADR cells. Time dependency ((a) and (c)) and concentration dependency (b) of MDR1 mRNA and P-gp expression in 48 h after incubation with CH were examined.

(a) RT-PCR

(b) RT-PCR

(c) Western blot
