Evaluation of ABCB1 gene expression in MCF-7 cells by RT-qPCR. The delta–delta CT method was used to determine the fold change for ABCB1 gene relative expression in MCF-7 cells that were treated with DOX and/or DIL for 48 h. The values represent the mean ± SD (n = 2). *Significantly different from corresponding DOX at p-value < 0.05
