Paper Abstract

PDT-induced HeLa cells apoptosis was evidenced by morphological changes, DNA fragmentation and decrease of mitochondria dehydrogenase activity. Apoptosis was associated with the formation of IP3 of photosensitized cells and rapid release of Ca2+ from intracellular pools. Vitamin E, which was added before irradiation, could significantly protect cells against cell death, indicating that reactive oxygen species (ROS) play an important role in apoptotic cell death.
