肿瘤和基质细胞之间的相互作用对于转移性黑色素瘤进展是必不可少的。我们证明了ESDN/DCBLD 2/CLCP 1在黑色素瘤扩散过程中在内皮细胞中起着至关重要的作用。准确地说,增加外渗和转移形成显示在ESDN-裸小鼠注射黑色素瘤细胞,即使原发性肿瘤生长,血管通透性,血管生成没有增强。有趣的是,由于在ESDN缺陷细胞中存在更高水平的E-选择素转录物/蛋白,观察到黑素瘤细胞与ESDN耗尽的内皮细胞的粘附改善。在人内皮细胞中,ESDN与E-选择素之间存在明显的相关性。最重要的是,我们的数据显示,西咪替丁,一种E-选择素抑制剂,能够阻断细胞粘附,外渗,并在ESDN-null小鼠转移形成,ESDN在E-选择素转录上调的主要作用,根据我们的数据可能与STAT 3。基于我们的研究结果,我们提出了ESDN在黑色素瘤扩散过程中的保护作用,并揭示了其治疗潜力。
An interactive crosstalk between tumor and stroma cells is essential for metastatic melanoma progression. We evidenced that ESDN/DCBLD2/CLCP1 plays a crucial role in endothelial cells during the spread of melanoma. Precisely, increased extravasation and metastasis formation was revealed in ESDN-null mice injected with melanoma cells, even if the primary tumor growth, vessel permeability, and angiogenesis were not enhanced. Interestingly, improved adhesion of melanoma cells to ESDN-depleted endothelial cells was observed, due to the presence of higher levels of E-selectin transcripts/proteins in ESDN-defective cells. In accordance with these results, anticorrelation was observed between ESDN and E-selectin in human endothelial cells. Most importantly, our data revealed that cimetidine, an E-selectin inhibitor, was able to block cell adhesion, extravasation, and metastasis formation in ESDN-null mice, underlying a major role of ESDN in E-selectin transcription upregulation, which according to our data may presumably be linked to STAT3. Based on our results, we propose a protective role for ESDN during the spread of melanoma and reveal its therapeutic potential.
