| 中文摘要: |
| 放射治疗是治疗恶性肿瘤的重要手段之一。临床上常因正常组织耐受剂量的限制而不能给予肿瘤足够的照射剂量，而造成治疗失败，因此，如何提高肿瘤对射线的敏感性是临床肿瘤放疗面临的突出问题。放射增敏剂作为一种增强肿瘤放疗敏感性、提高放疗疗效的药物，通过增加辐射诱导的氧自由基及DNA损伤、调控放疗关键分子靶点以达到放射增敏目的。本文结合放射增敏剂在放射治疗中的应用，概述了放射增敏剂的发展现状及相关领域的研究进展，并对多种放射增敏剂的作用机制进行了简要综述，以期为进一步研究放射增敏调控的分子机制、促进放射增敏剂的研发，以及设计新的策略改善放射治疗结果提供帮助。 |
| 英文摘要: |
| Radiotherapy is one of the important methods for treating malignant tumors. However, due to the limitation of normal tissue tolerance dose, it is impossible to give a sufficient irradiation dose to the tumor, which causes treatment failure. Therefore, how to improve the sensitivity of the tumor to radiation is a prominent problem in tumor radiotherapy. Radiosensitizers can enhance the sensitivity of tumor radiotherapy and improve the efficacy of radiotherapy, through accelerating DNA damage,producing free radicals and regulating key molecular targets. This paper summarized the applications of radiosensitizers in radiotherapy, the development status of radiosensitizers and research progresses in the related fields.Furthermore, the possible mechanisms of how radiosensitizers enhance the sensitivity of tumors were also briefly reviewed. This review will elucidate the detailed molecular mechanisms of radiosensitization regulation, promote the development of radiosensitizers, and facilitate the development of new strategies to improve radiotherapy efficiency. |
