概要	In recent years, talaporfin sodium-mediated photodynamic therapy (NPe6-PDT) against glioblastoma (GBM) has been developed; however molecular mechanism of NPe6-PDT-dependent GBM cell death has not yet been well elucidated. Therefore, we investigated the molecular machinery of GBM cell death induced by NPe6-PDT using human GBM cell lines. As a result, activation of the stress signaling and suppression of the survival signaling were observed during NPe6-PDT-dependent GBM cell death. In addition, we succeeded in establishment of GBM cell lines with acquired NPe6-PDT resistance and currently investigating further about the machinery which regulates NPe6-PDT resistance in these cells.
