Research Abstract |
As ABCG2 transporter, a main cause of chemo-resistance in cancer stem cells, also transports porphyrin to extracellular space, ABCG2 may be an effective target for photodynamic therapy. In this study, we proofed that gefitinib, a clinical available ABCG2 inhibitor, reduced extra-cellular transportation of porphyrin and increase intra-cellular concentration of porphyrin, consequently, enhanced the treatment efficacy of photodynamic therapy using 5-aminolevulinic acid.
