We tested the novel hypothesis that EMMPRIN/CD147, a transmembrane glycoprotein overexpressed in breast cancer cells, has a previously unknown role in transforming fibroblasts to cancer-associated fibroblasts, and that cancer-associated fibroblasts in turn induce epithelial-to-mesenchymal transition of breast cancer cells. Co-culture of fibroblasts with breast cancer cells or treatment of fibroblasts with breast cancer cell conditioned culture medium or recombinant EMMPRIN/CD147 induced expression of α-SMA in the fibroblasts in an EMMPRIN/CD147-dependent manner and promoted epithelial-to-mesenchymal transition of breast cancer cells and enhanced cell migration potential. These findings support a novel role of EMMPRIN/CD147 in regulating the interaction between cancer and stroma.
我们检验了一个新假说,即跨膜糖蛋白 EMMPRIN/CD147 在乳腺癌细胞中过表达,它在将成纤维细胞转变成癌相关成纤维细胞方面具有未知的作用,而癌相关成纤维细胞又反过来诱导乳腺癌细胞发生上皮间质转化。成纤维细胞与乳腺癌细胞共培养或用乳腺癌细胞条件培养基或重组 EMMPRIN/CD147 处理成纤维细胞,以 EMMPRIN/CD147 依赖性方式诱导成纤维细胞中 α-SMA 的表达,并促进乳腺癌细胞的上皮间质转化和增强细胞迁移能力。这些发现支持 EMMPRIN/CD147 在调节癌症与基质之间相互作用方面的新作用。
