细胞质染色质片段(CCF)被细胞质DNA传感器环GMP-AMP合成酶(cGAS)识别,激活cGAS - sting(环GMP-AMP合成酶-干扰素基因刺激因子)通路,促进炎症因子的产生和乳腺癌转移。然而,CCF在肿瘤细胞中形成的机制以及CCF激活cGAS促进乳腺癌转移的机制尚不清楚。本研究发现zeste homolog 2的增强子(enhancer of zeste homolog 2, EZH2)可以促进CCF的形成,激活cGAS-STING通路,促进乳腺癌转移。进一步研究发现,EZH2介导的CCF形成依赖于高迁移率基团A1 (HMGA1),而EZH2的稳定性需要泛素特异性肽酶7 (USP7),表明EZH2- HMGA1 - USP7复合物调节CCF的形成。此外,EZH2可以通过CCF激活cGAS,需要USP7去泛素化cGAS并稳定cGAS。体内实验结果表明EZH2可通过CCF促进乳腺癌转移。我们的发现强调了乳腺癌转移的新靶点。靶向EZH2-CCF-cGAS轴可能是抑制乳腺癌转移的潜在治疗策略。
Cytoplasmic chromatin fragments (CCF) are recognized by the cytoplasmic DNA sensor cyclic GMP-AMP synthase (cGAS), which activates the cGAS–STING (cyclic GMP-AMP synthase-stimulator of interferon genes) pathway and promotes the production of inflammatory factors and breast cancer metastasis. However, the mechanisms by which CCF are formed in tumor cells and CCF activation cGAS promotes breast cancer metastasis remain unclear. Here, we report that the enhancer of zeste homolog 2 (EZH2) can promote the formation of CCF and activate the cGAS–STING pathway to promote breast cancer metastasis. Further research found that the EZH2-mediated CCF formation depended on high mobility group A1 (HMGA1), while the stability of EZH2 required ubiquitin-specific peptidase 7 (USP7), indicating that the EZH2–HMGA1–USP7 complex regulated CCF formation. Moreover, EZH2 can activate cGAS through CCF, requiring USP7 to deubiquitinate cGAS and stabilize cGAS. In vivo experimental results showed that EZH2 could promote breast cancer metastasis through CCF. Our findings highlight a new target for breast cancer metastasis. Targeting the EZH2–CCF–cGAS axis may be a potential therapeutic strategy for inhibiting breast cancer metastasis.
