癌症的转移和耐药性是相互关联的现象,但这种联系的分子基础尚不清楚。我们发现了癌细胞、髓细胞和内皮细胞之间的旁分泌信号网络,它驱动着乳腺癌的两个过程。通过转录过度激活或4 q21扩增过表达CXCL 1和2的癌细胞在转移位点中存活。CXCL 1/2吸引CD 11b + Gr 1+骨髓细胞进入肿瘤,产生包括S100 A8/9在内的趋化因子,增强癌细胞存活。虽然化疗药物杀死癌细胞,但这些治疗引发平行的基质反应,导致内皮细胞和其他基质细胞产生TNF-α。肿瘤坏死因子-α(TNF-α)可增强CXCL 1/2在癌细胞中的表达,从而扩增CXCL 1/2-S100 A8/9环,导致化疗耐药。CXCR 2阻断剂打破了这种循环,增强了化疗对乳腺肿瘤的疗效,特别是对转移的疗效。这种内皮细胞-癌细胞-髓样细胞信号相互作用的网络提供了一种连接化疗耐药性和转移的机制,并提供了干预的机会。
Metastasis and chemoresistance in cancer are linked phenomena but the molecular basis for this link is unknown. We uncovered a network of paracrine signals between carcinoma, myeloid and endothelial cells that drives both processes in breast cancer. Cancer cells that overexpress CXCL1 and 2 by transcriptional hyperactivation or 4q21 amplification are primed for survival in metastatic sites. CXCL1/2 attract CD11b+Gr1+ myeloid cells into the tumor, which produce chemokines including S100A8/9 that enhance cancer cell survival. While chemotherapeutic agents kill cancer cells, these treatments trigger a parallel stromal reaction leading to TNF-α production by endothelial and other stromal cells. TNF-α heightens the expression of CXCL1/2 in cancer cells, thus amplifying the CXCL1/2-S100A8/9 loop and causing chemoresistance. CXCR2 blockers break this cycle, augmenting the efficacy of chemotherapy against breast tumors and particularly against metastasis. This network of endothelial-carcinoma-myeloid signaling interactions provides a mechanism linking chemoresistance and metastasis, with opportunities for intervention.
