Abstract

Aim

The tumor microenvironment (TME) of non-small cell lung cancer (NSCLC) is highly heterogeneous and is involved in tumorigenesis and resistance to therapy. Among the cells of the TME, endothelial cells are associated with the latter processes through endothelial-to-mesenchymal transition (EndMT). During EndMT, endothelial cells (ECs) progressively lose their endothelial phenotype in favor of a mesenchymal phenotype, which favors the production of cancer-associated fibroblasts (CAFs). Our study aimed to investigate the consequences of exposure to different lung tumor secretomes on EC phenotype and plasticity.

Materials and Methods

Conditioned media (CM) were prepared from the tumor cell lines A549, H1755, H23, H1437, and H1975. Proliferation and migration of ECs treated with these CMs were assessed by Cyquant and Incucyte technologies, respectively. The angiogenic capacity of ECs was assessed by following tubulogenesis on Matrigel. Phenotypic changes in treated ECs were detected by flow cytometry. Morphological analysis of actin fibers was performed by immunohistochemistry, while proteomic analysis by mass spectrometry was used to identify the protein content of secretomes.

Results

A change of the endothelial phenotype was found when human umbilical vein endothelial cells (HUVECs) were treated with different CMs. This phenotypic change was associated with a morphological change, an increase in both stress fiber expression and spontaneous migration. Furthermore, an increase in mesenchymal markers (α-SMA and CD44) confirmed the phenotypic changes. However, the secretomes did not modify the rate of double-labeled cells (vWF+/α-SMA+ or CD31+/CD44+). Proteomic analysis identified potential targets involved in the EndMT with therapeutic relevance.

Conclusion

Taken together, these data suggest that CMs can induce partial EndMT.

非小细胞肺癌细胞分泌组通过部分内皮向间质转化诱导内皮可塑性
目的非小细胞肺癌(NSCLC)的肿瘤微环境(tumor microenvironment, TME)具有高度异质性,参与肿瘤发生和耐药过程。在TME细胞中,内皮细胞通过内皮-间充质转化(EndMT)参与后一过程。在EndMT过程中,内皮细胞(ECs)逐渐失去其内皮表型,转而支持间充质表型,这有利于癌症相关成纤维细胞(CAFs)的产生。我们的研究旨在探讨暴露于不同的肺肿瘤分泌组对EC表型和可塑性的影响。材料与方法从肿瘤细胞系A549、H1755、H23、H1437和H1975制备条件培养基(CM)。用Cyquant和Incucyte技术分别评估这些CMs处理的ECs的增殖和迁移。通过在Matrigel上跟踪血管生成来评估ECs的血管生成能力。流式细胞术检测处理后ECs的表型变化。免疫组织化学对肌动蛋白纤维进行形态学分析,质谱分析对分泌组蛋白含量进行蛋白质组学分析。结果人脐静脉内皮细胞(HUVECs)经不同CMs处理后,内皮表型发生变化。这种表型变化与形态改变、应激纤维表达增加和自发迁移有关。此外,间充质标志物(α-SMA和CD44)的增加证实了表型变化。然而,分泌组没有改变双标记细胞(vWF+/α-SMA+或CD31+/CD44+)的率。蛋白质组学分析确定了与治疗相关的EndMT相关的潜在靶点。综上所述,这些数据表明CMs可以诱导部分EndMT。
