摘要:
电离辐射易引起DNA双链断裂(DSB),Ku蛋白作为异二聚体,主要参与非同源末端联接修复DSB。Ku蛋白在维持端粒结构发挥至关重要的作用。在人的不同肿瘤中,Ku蛋白有着异常表达,且Ku蛋白的表达和功能与肿瘤放化疗抵抗有关。通过抑制Ku蛋白可增强放化疗敏感性。因此,Ku蛋白可作为放化疗增敏的靶点。
Abstract:
Ionizing radiation can cause double strand break (DSB), Ku protein as a heterologous dimmer; mainly join in non-homologous end-joining repair pathway. Ku protein plays a crucial role in maintaining telomere structure. There is an abnormal expression of Ku protein in human different tumors. The expression and function of Ku protein is relate to resistance of tumor radiotherapy and chemotherapy. Inhibition of Ku protein can enhance the sensitivity of radiotherapy and chemotherapy. Therefore, Ku protein can be used as target of enhancement of radiotherapy and chemotherapy.
