Honokiol suppresses the expression level of ABBC1/MRP1 in mammary carcinoma cells. Total RNA was collected from MCF-7 cells (A) and MDA-MB-231 (B) cells treated with 10 or 20 μM honokiol for 48 h (DMSO was used for the control). Expression level of ABCC1 mRNA in MCF-7 cells (A) and MDA-MB-231 cells (B) were analyzed by qRT-PCR. GAPDH was used for normalization. Data are mean of ± SE (n=3). *p=0.0006 versus control treatment; **p=0.016 versus control treatment; +p=0.01 versus control treatment; ++p=0.004 versus control treatment. MCF-7 (C) and MDA-MB-231 (D) cells were treated with 10 or 20 μM honokiol for 48 h (DMSO was used for the control) prior to cell lysis. Cell lysates were resolved with SDS-PAGE and immunoblotted with antibodies recognizing MRP1, and β-tubulin was used as a loading control.
