肿瘤转移是世界范围内死亡的主要原因,涉及由多个步骤组成的极其复杂的过程。我们之前的研究表明,小鼠细胞凋亡信号调节激酶1(ASK 1)缺陷会减弱实验性肺转移模型中的肿瘤转移。然而,由ASK 1调节的肿瘤转移的步骤仍不清楚。在这里,我们发现小鼠中的ASK 1缺陷在转移的最初几个小时内促进自然杀伤(NK)细胞介导的血管内肿瘤细胞清除。在对肿瘤接种的反应中,ASK1缺陷上调了免疫反应相关基因,包括干扰素γ(IFNγ)。我们还发现,NK细胞是这些抗转移表型所必需的。ASK1缺陷可能通过诱导NKG2D(NK细胞的关键活化受体)的配体,导致NK细胞进一步募集到肺中,从而增加了对NK细胞具有化学吸引力的细胞因子的产生。这些结果表明,ASK1负调节NK细胞依赖性抗肿瘤免疫,ASK1靶向治疗可以为癌症免疫治疗提供一种新的工具,以克服肿瘤转移。ASK 1以NK细胞依赖性方式调节肿瘤肺转移的初始步骤。小鼠中的ASK1缺陷增强NK细胞的细胞因子产生和NK细胞对肿瘤接种的应答募集。ASK 1缺陷导致NKG2D配体H60上调,这可能增加NK细胞依赖性血管内肿瘤细胞清除。
Tumor metastasis is the leading cause of death worldwide and involves an extremely complex process composed of multiple steps. Our previous study demonstrated that apoptosis signal‐regulating kinase 1 (ASK1) deficiency in mice attenuates tumor metastasis in an experimental lung metastasis model. However, the steps of tumor metastasis regulated by ASK1 remain unclear. Here, we showed that ASK1 deficiency in mice promotes natural killer (NK) cell‐mediated intravascular tumor cell clearance in the initial hours of metastasis. In response to tumor inoculation, ASK1 deficiency upregulated immune response‐related genes, including interferon‐gamma (IFNγ). We also revealed that NK cells are required for these anti‐metastatic phenotypes. ASK1 deficiency augmented cytokine production chemoattractive to NK cells possibly through induction of the ligand for NKG2D, a key activating receptor of NK cells, leading to further recruitment of NK cells into the lung. These results indicate that ASK1 negatively regulates NK cell‐dependent anti‐tumor immunity and that ASK1‐targeted therapy can provide a new tool for cancer immunotherapy to overcome tumor metastasis. ASK1 regulates the initial steps of tumor lung metastasis in an NK cell‐dependent fashion. ASK1 deficiency in mice enhances cytokine production of NK cells and NK cell recruitment in response to tumor inoculation. ASK1 deficiency leads to upregulation of NKG2D ligands H60, which might augment NK cell‐dependent intravascular tumor cell clearance.
