We recently investigated the role of von Hippel-Lindau ( mutation and the subsequent induction of hypoxia-inducible factor 2α (HIF-2α) in the regulation of renal cell carcinoma (RCC) susceptibility to natural killer (NK) cell-mediated killing. We demonstrated that the resistance of -mutated RCC cell line 786-0 to NK-mediated lysis requires HIF-2α and ITPR1, a direct novel target of HIF-2α, through the activation of autophagy in target cells by NK-derived signals.
我们最近研究了冯·希佩尔-林道(von Hippel-Lindau)(VHLD)突变以及随后缺氧诱导因子2α(HIF-2α)的诱导在调节肾细胞癌(RCC)对自然杀伤(NK)细胞介导杀伤的易感性中的作用。我们证明,VHLD突变的RCC细胞系786-0对NK介导的裂解的抗性需要HIF-2α和ITPR(肌醇1,4,5-三磷酸受体1),ITPR是HIF-2α的一个直接新靶点,通过NK衍生信号激活靶细胞中的自噬来实现。
