许多接受头颈部癌症治疗的患者由于辐射损伤而经历唾液腺功能减退。了解辐射处理引起的细胞损伤的机制对于设计辐射防护方法是重要的。此外,认识到辐射的间接影响和可能改变唾液分泌的全身反应至关重要。在本研究中,使用137Cs伽马射线辐照器双侧或使用小动物辐射研究平台(SARRP)单侧向小鼠颌下腺(SMG)提供辐射。在3,24和48小时的分析表明,在mRNA和蛋白质表达的动态变化的SMG照射双边。 使用SARRP的单侧照射引起了照射SMG的类似变化,以及未照射对侧SMG的显著脱靶、旁观者效应。总结:由于旁观者效应,小鼠基因表达的快速变化发生在照射后数小时内的照射唾液腺和未照射的对侧腺体中。
Many patients treated for head and neck cancers experience salivary gland hypofunction due to radiation damage. Understanding the mechanisms of cellular damage induced by radiation treatment is important in order to design methods of radioprotection. In addition, it is crucial to recognize the indirect effects of irradiation and the systemic responses that may alter saliva secretion. In this study, radiation was delivered to murine submandibular glands (SMGs) bilaterally, using a 137Cs gamma ray irradiator, or unilaterally, using a small-animal radiation research platform (SARRP). Analysis at 3, 24 and 48 h showed dynamic changes in mRNA and protein expression in SMGs irradiated bilaterally. Unilateral irradiation using the SARRP caused similar changes in the irradiated SMGs, as well as significant off-target, bystander effects in the non-irradiated contralateral SMGs. Summary: Rapid changes in murine gene expression occur in irradiated salivary glands within hours of irradiation, and in non-irradiated contralateral glands, due to bystander effects.
