Abstract
Photodynamic therapy (PDT) shows a limited antitumor effect in treating gastrointestinal tumors because of improper light penetration or insufficient photosensitizer uptake. The aim of this study was to evaluate the cytotoxic effect of PDT combined with paclitaxel on in vitro cancer cells. In vitro photodynamic therapy was performed in gastric cancer cells (NCI-N87) and bile duct cancer cells (YGIC-6B) using verteporfin (2 μg mL−1) and a ptH light source (1?000 W, Oriel Co.) with 665–675 nm narrow band pass filter. Cytotoxicity was compared using the MTT assay between cancer cells treated with PDT alone or pretreated with paclitaxel (IC25 ). Apoptotic changes were evaluated using DAPI staining, DNA fragmentation analysis, Annexin V-FITC apoptosis assay, cell cycle analysis, and western blots for cytochrome c, Bax, and Bid. The PDT-induced cytotoxicity was potentiated by pretreating with low dose paclitaxel (P < 0.001). The enhanced cytotoxicity was due to an augmented apoptotic response mediated by exaggerated cytochrome c released from mitochondria, without Bax or Bid activation. These results show that paclitaxel pretreatment enhances PDT-mediated cancer therapy.
