Abstract: Radiation-induced skin injury is a common complication of patients receiving radiotherapy. Its pathogenesis is complicated and varies greatly with individual patients. Therefore, it is necessary to develop the drugs for prevention and treatment of radiation-induced skin injury. Chinese prickly ash (Zanthoxylum bungeanum) is a common medicine used for skin diseases in traditional Chinese medicine. In this study, the radio-protective effect of the root bark extract of Zanthoxylum piasezkii (ZPE) on HaCaT was investigated and its mechanism was preliminary discussed. The results showed that 2 mg/mL ZPE could protect HaCaT cells from damage induced by 8.0 Gy γ ray irradiation, and could reduce apoptosis and necrosis of HaCaT cells. The mechanism may be related to the reduction of the secretion of IL-1β and IL-6, the level of ROS and the phosphorylation of p38 and JNK proteins. This work provides a theoretical basis for the development of preventive and therapeutic drugs for radiation-induced skin injury.

Key words: Radiation-induced skin injury, Zanthoxylum piasezkii, radiation protection, human keratinocytes
