Photodynamic therapy of brain tumor stem cells overcomes drug-resistance in preclinical models (Conference Presentation)
Author(s): Bryan Q. Spring

Paper Abstract

Standard chemoradiation often enriches drug-resistant tumor cell populations that can lead to recurrent and treatment-refractory disease. For instance, preclinical models of several cancers suggest that the cancer stem cell subpopulation becomes enriched and re-populates the tumor milieu following conventional therapies. Here, we show evidence that photodynamic therapy (PDT) is effective against several patient-derived glioblastoma stem cell cultures. Moreover, sub-lethal PDT results in re-sensitization of cancer cell phenotypes with induced drug-resistance to chemotherapy. This talk will also introduce some of our efforts to establish a new program aimed at developing personalized and targeted PDT to overcome drug-resistance.
