在这里,我们专注于早期肺腺癌(esLUAD),这是最常见的肺癌组织学亚型的临床显着的组织学亚型的分子特征。在肺腺癌中,组织学是异质性的,并且与肿瘤侵袭和不同的临床结果相关。我们提出了一种区分esLUAD中侵袭性和非侵袭性肿瘤的基因特征。使用基因特征,我们估计侵袭性评分,其与多个独立队列中esLUAD患者的存活率以及肺癌细胞系中的侵袭性表型密切相关。调控网络分析鉴定极光激酶为基因签名的主要调控因子之一,并且在体外和侵袭性肺腺癌的鼠模型中极光激酶的扰动降低了肿瘤侵袭。我们的研究揭示了极光激酶作为治疗早期浸润性肺腺癌的治疗靶点。驱动肺腺癌(LUAD)侵袭和转移的分子因素尚未完全了解。在这里,作者使用一种整合网络方法来识别LUAD中侵袭性的基因特征,并揭示Aurora激酶作为侵袭的主要调节因子。
Here we focus on the molecular characterization of clinically significant histological subtypes of early-stage lung adenocarcinoma (esLUAD), which is the most common histological subtype of lung cancer. Within lung adenocarcinoma, histology is heterogeneous and associated with tumor invasion and diverse clinical outcomes. We present a gene signature distinguishing invasive and non-invasive tumors among esLUAD. Using the gene signatures, we estimate an Invasiveness Score that is strongly associated with survival of esLUAD patients in multiple independent cohorts and with the invasiveness phenotype in lung cancer cell lines. Regulatory network analysis identifies aurora kinase as one of master regulators of the gene signature and the perturbation of aurora kinases in vitro and in a murine model of invasive lung adenocarcinoma reduces tumor invasion. Our study reveals aurora kinases as a therapeutic target for treatment of early-stage invasive lung adenocarcinoma. The molecular factors that drive invasiveness and metastasis in lung adenocarcinoma (LUAD) are not completely understood. Here, the authors use an integrative network approach to identify a gene signature of invasiveness in LUAD, and reveal Aurora kinases as master regulators of invasion.
