Abstract

Cell migration is a critical contributor to metastasis. Cytokine production and its role in cancer cell migration have been traditionally associated with immune cells. We find that the histone methyltransferase Mixed-Lineage Leukemia 1 (MLL1) controls 3D cell migration via cytokines, IL-6, IL-8, and TGF-β1, secreted by the cancer cells themselves. MLL1, with its scaffold protein Menin, controls actin filament assembly via the IL-6/8/pSTAT3/Arp3 axis and myosin contractility via the TGF-β1/Gli2/ROCK1/2/pMLC2 axis, which together regulate dynamic protrusion generation and 3D cell migration. MLL1 also regulates cell proliferation via mitosis-based and cell cycle-related pathways. Mice bearing orthotopic MLL1-depleted tumors exhibit decreased lung metastatic burden and longer survival. MLL1 depletion leads to lower metastatic burden even when controlling for the difference in primary tumor growth rates. Combining MLL1-Menin inhibitor with paclitaxel abrogates tumor growth and metastasis, including preexistent metastasis. These results establish MLL1 as a potent regulator of cell migration and highlight the potential of targeting MLL1 in patients with metastatic disease.

摘要

细胞迁移是转移的关键贡献者。细胞因子的产生及其在癌细胞迁移中的作用传统上与免疫细胞有关。我们发现组蛋白甲基转移酶混合谱系白血病 1（MLL1）通过癌细胞自身分泌的细胞因子 IL-6、IL-8 和 TGF-β1 控制 3D 细胞迁移。MLL1 与其支架蛋白 Menin 通过 IL-6/8/pSTAT3/Arp3 轴控制肌动蛋白丝组装，并通过 TGF-β1/Gli2/ROCK1/2/pMLC2 轴控制肌球蛋白收缩，共同调节动态突出生成和 3D 细胞迁移。MLL1 还通过有丝分裂相关和细胞周期相关途径调节细胞增殖。携带原位 MLL1 耗尽肿瘤的小鼠表现出肺转移负担降低和存活时间延长。即使控制原发性肿瘤生长速度的差异，MLL1 耗竭也会导致较低的转移负担。将 MLL1-Menin 抑制剂与紫杉醇联合使用可阻断肿瘤生长和转移，包括先前存在的转移。这些结果确立了 MLL1 作为细胞迁移的有效调节剂，并强调了在转移性疾病患者中靶向 MLL1 的潜力。
