摘要
Tumor-associated macrophages (TAMs) are important monocytes in the breast cancer microenvironment. They facilitate the distant metastasis of breast cancer. However, the detailed mechanisms of TAM-derived cancer metastasis have not been clearly elucidated. Here, we demonstrate that PRMT1 is essential for TAM-mediated breast cancer cell migration and metastasis. TAMs increase EZH2 stability by stimulating PRMT1-mediated meR342-EZH2 formation through the secretion of interleukin-6 (IL-6) cytokine. Moreover, high expression levels of TAMs are positively correlated with PRMT1, meR342-EZH2, and EZH2 expression in breast cancer patients. Our study presents a novel mechanism of TAM-induced breast cancer metastasis via the IL-6-PRMT1-meR342-EZH2 axis.
