Figure 1

Effect of Tacrolimus (FK506) on multidrug resistance-associated protein 1 (MRP1) levels in U87MG and C6 cells. Cells were treated with FK506 (7, 15, and 30 ng/mL) for 24 h. MRP1 mRNA levels were measured by RT-qPCR in U87MG cells (A) and C6 cells (B). Graphs represent the values normalized by actin beta (ACTB). MRP1-positive cells were quantified by flow cytometry in U87MG cells (C) and C6 cells (D). White bars represent non-glioblastoma stem-like cells (GSCs) and black bars represent glioblastoma stem-like cells (GSCs).
