A number of genes are differentially expressed in MCF-7 and MCF-7/ADR vs. MCF-7 + psoralen and MCF-7/ADR + psoralen. Ribosomal RNA-free total RNA extracts were prepared from 24 h derived from each of 3 donors and subjected to RNA-seq analysis. A heat map was generated using the significant DE genes with a P value of 0.01
