Photodynamic
Therapy (PDT) is a non-invasive method with minimal side effects in the
treatment of cancer. The photosensitizing agent, one of the FDT components,
stimulates the generation of reactive oxygen species and / or singlet oxygen
radicals in cancer cells with light that is at appropriate wavelength. The
light source and the photosensitizing agent alone are reported to have no toxic
effect. However, in some of the studies, there are also reports that only laser
applications can have effects on cell lines. For this purpose, effects of the
808 nm laser light source at 50 J/cm2, 100 J/cm2 and 150
J/cm2 were investigated DNA synthesis of C6 glioma, Caco-2 colon
cancer, L929 fibroblast and prostate cancer PC-3 cell that are frequently
studied. It was found that except for Caco-2 cells, laser application decreased
DNA synthesis in all other cell lines at 24 hours, but this effect was maintained
at other hours. As a result, although laser application may have effects on DNA
synthesis at short time depending on the dose and cell line used, these effects
should be investigated in the context of other cellular mechanisms.
