| Outline of Final Research Achievements |
Radiation therapy is effective for head and neck squamous cell carcinoma and useful for organ preservation, however radiation induces permanent xerostomia due to salivary gland damage. It is reported that ramapycin, mTOR inhibitor, removes intracellular reactive oxygen species(ROS) in human oral keratinocytes and prevents senescence. This study shows rapamycin inhibits intracellular ROS production in normal salivary gland cell. This result indicates rapamycin inhibits ROS in irradiated salivary gland cells, too. Moreover, rapamycin might protect radiation induced salivary gland disorder.
