Outline of Final Research Achievements |
Glioblastoma is refractory to chemotherapy and radiotherapy, and even if they are combined, the survival time extends only for months. In particular, for prolonging survival time, an effective strategy for tumor stem cells is necessary. Generally, ABCG2 responsible for drug excretion is highly expressed in tumor stem cells, and control of ABCG2 is promising for overcoming treatment resistance. In this study, we discovered that lapatinib is promising as an ABCG 2 inhibitor by drug discovery molecular design, and conducted fundamental research for development of the next generation photodynamic therapy targeting tumor stem cells.
