肿瘤微环境(TME)是乳腺癌进展的重要介质。肿瘤相关成纤维细胞是TME的主要成分,可能来源于组织相关成纤维细胞或浸润性间充质基质细胞(MSCs)。癌细胞激活成纤维细胞并将MSCs募集到TME的机制在很大程度上尚不清楚,但可能包括沉积一个促肿瘤的分泌体。分泌的胚胎蛋白结节与乳腺癌临床分期相关,促进肿瘤生长、转移和血管生成。在这里,我们表明,在人类三阴性乳腺癌中,结节表达与激活的成纤维细胞的存在相关,并直接诱导癌症相关成纤维细胞的表型。我们进一步证明,Node通过同时改变趋化因子(例如CXCL1)、细胞因子(例如IL-6)和生长因子(例如PDGFRA)的水平来重新编程癌细胞分泌体,导致MSC趋化性的改变。因此,我们展示了一种迄今未被认识的机制,该机制潜在于TME的动态监管。
The tumor microenvironment (TME) is an important mediator of breast cancer progression. Cancer-associated fibroblasts constitute a major component of the TME and may originate from tissue-associated fibroblasts or infiltrating mesenchymal stromal cells (MSCs). The mechanisms by which cancer cells activate fibroblasts and recruit MSCs to the TME are largely unknown, but likely include deposition of a pro-tumorigenic secretome. The secreted embryonic protein NODAL is clinically associated with breast cancer stage and promotes tumor growth, metastasis, and vascularization. Herein, we show that NODAL expression correlates with the presence of activated fibroblasts in human triple-negative breast cancers and that it directly induces Cancer-associated fibroblasts phenotypes. We further show that NODAL reprograms cancer cell secretomes by simultaneously altering levels of chemokines (e.g., CXCL1), cytokines (e.g., IL-6) and growth factors (e.g., PDGFRA), leading to alterations in MSC chemotaxis. We therefore demonstrate a hitherto unappreciated mechanism underlying the dynamic regulation of the TME.
