| Outline of Final Research Achievements |
Cancer remains one of the leading causes of human mortality worldwide. Radiation and chemotherapy are commonly used for cancer treatment; however, the combination of these therapies and surgery do not completely eradicate cancer cells. Near infrared radiation (NIR) is a low energy form of radiation that exerts multiple effects on mammalian cells. Previous studies have reported that NIR induces DNA double strand breaks and apoptosis of cancer cells. In the present study, a 915 nm laser was used to examine the effects of NIR on pancreatic cancer cells. Irradiation of pancreatic cancer cells using a 915 nm laser significantly induced caspase 3 activation and apoptosis. In addition, the combination of gemcitabine treatment and a 915 nm laser synergistically increased the number of apoptotic cells. The results of the present study indicate the use of infrared irradiation and chemotherapy may be a possible therapy for the treatment of cancer.
