在这项研究中,我们研究了西妥昔单抗介导的HNSCC放射增敏的机制。照射后HNSCC细胞缺氧诱导因子-1α(α)表达上调,其机制与HIF-1α蛋白从头合成有关。西妥昔单抗可完全消除辐射诱导的HIF-1α表达上调。组件性表达的HIF-1α的实验升高取消了西妥昔单抗对HNSCC细胞的放射增敏作用,而siRNA或小分子抑制剂下调HIF-1α则增强了耐西妥昔单抗的HNSCC细胞对西妥昔单抗加辐射的反应。我们的数据表明,西妥昔单抗通过抑制辐射诱导的HIF-1α表达上调,使癌细胞对电离辐射敏感。
In this study, we investigated the mechanisms underlying cetuximab-mediated radiosensitization of HNSCC. Irradiation of HNSCC cells upregulated hypoxia-inducible factor-1 alpha (HIF-1α) via a mechanism involving de novo synthesis of HIF-1α protein. Radiation-induced upregulation of HIF-1α was completely abolished by concurrent treatment of HNSCC cells with cetuximab. Experimental elevation of constitutively expressed HIF-1α abolished cetuximab-mediated radiosensitization in HNSCC cells, whereas downregulation of HIF-1α by siRNA or a small molecule inhibitor enhanced responses of cetuximab-resistant HNSCC cells to cetuximab plus radiation. Our data suggest that cetuximab sensitizes cancer cells to ionizing radiation in part through inhibition of radiation-induced upregulation of HIF-1α.
