Abstract

Significance: Here, RNAi library screening reveals that multiple G2/M and kinetochore components, including TTK/monopolar spindle 1, modulate TNFα-induced NF-κB activation, cell survival, and genotoxicity, underscoring their potential importance as therapeutic targets in HNSCC.

功能性 RNAi 筛选确定 G2/M 和着丝点成分是头颈部鳞状细胞癌中 TNFα/NF-κB 促生存信号的调节因子。
在包括头颈部鳞状细胞癌(HNSCC)在内的多种癌症中,转录因子 NF-κB 促进了癌细胞对肿瘤坏死因子-α(TNFα)介导的细胞毒性的免疫和辐射抗性。癌症基因组图谱(The Cancer Genome Atlas,TCGA)发现,约40%的HNSCC存在TNFα/NF-κB信号轴的基因组改变。然而,鉴定导致TNFα/NF-κB异常激活和耐药性的治疗靶点一直是个挑战。在这里,我们利用平行的 NF-κB β-内酰胺酶报告和细胞活力测定法,在一种 HNSCC 细胞系中进行了功能性 RNAi 筛选,以确定 TNFα 诱导的 NF-κB 激活和细胞活力的调节因子。除了典型 TNFα/NF-κB 信号转导的多种成分外,我们还发现了 WNT、NOTCH 和 TGFβ 通路的成分,我们以前曾证实这些成分有助于 NF-κB 的非典型激活。意想不到的是,我们还观察到多种 G2/M 细胞周期激酶(AURKA、PLK1、WEE1、TTK)和结构性动点核/微管成分(NDC80、NUF2)调节 TNFα 诱导的 NF-κB 激活和细胞活力。其中几个靶点抑制了 TNF 诱导的 RELA 核转位,这与之前将 NF-B 激活与 G2/M 激酶或微管组装联系起来的报道一致。对未被充分研究的有丝分裂激酶TTK/MPS1的进一步研究表明,抑制或耗竭TTK/MPS1可减少TNFα诱导的RELA核转位,促进细胞死亡、DNA损伤、多倍体和有丝分裂灾难,从而导致放射致敏。总之,我们的RNAi筛选确定了G2/M细胞周期检查点/着丝点元件与NF-κB活性之间的关键联系,以及可使HNSCC细胞对TNFα或辐射敏感的靶点。
