Interactions between cells in the tumor microenvironment (TME) shape cancer progression and patient prognosis. To gain insights into how the TME influences cancer outcomes, we derive gene expression signatures indicative of signaling between stromal fibroblasts and cancer cells, and demonstrate their prognostic significance in multiple and independent squamous cell carcinoma cohorts. By leveraging information within the signatures, we discover that the HB-EGF/EGFR/MAPK axis represents a hub of tumor-stroma crosstalk, promoting the expression of CSF2 and LIF and favoring the recruitment of macrophages. Together, these analyses demonstrate the utility of our approach for interrogating the extent and consequences of TME crosstalk.
肿瘤微环境(TME)中的细胞间相互作用塑造了癌症进展和患者预后。为深入了解TME如何影响癌症结局,我们得出了指示基质成纤维细胞与癌细胞之间信号传导的基因表达特征,并在多个独立的鳞状细胞癌队列中证明了它们的预后意义。通过利用这些特征中的信息,我们发现HB-EGF/EGFR/MAPK轴代表肿瘤-基质相互作用的枢纽,促进CSF2和LIF的表达并有利于巨噬细胞的募集。总之,这些分析证明了我们的方法在探究TME相互作用的程度和后果方面的实用性。
