NFIC1, the longest isoform of NFIC, is essential for the regulation on spatiotemporal expression of drug-metabolizing genes in liver. However, the role of NFIC1 in breast cancer is not clear. Here we showed that increased expression of NFIC1 suppressed the migration and invasion of MCF-7 cells. NFIC1 overexpression increased the expression of IFNB1, IFNL1, IFNL2 and IFNL3, and the activation of interferon-mediated Jak-STAT pathway was enhanced by NFIC1 overexpression. Treatment with Jak-STAT pathway inhibitors, Filgotinib or Ruxolitinib, reversed the suppressive effects of NFIC1 overexpression on migration and invasion of MCF-7 cells. In addition, we found that MX1 and MX2, two target genes of Jak-STAT pathway, mediated the migration and invasion of MCF-7 cells. These results demonstrated that NFIC1 inhibited the migration and invasion in MCF-7 cells through interferon-mediated activation of Jak-STAT pathway, indicating that Jak-STAT pathway might be a potential therapeutic target for preventing breast cancer metastasis.
NFIC1 是 NFIC 的最长异构体,对肝脏中药物代谢基因的时空表达调控至关重要。然而,NFIC1 在乳腺癌中的作用尚不清楚。本研究表明,NFIC1 表达增加抑制 MCF-7 细胞的迁移和侵袭。NFIC1 过表达增加 IFNB1、IFNL1、IFNL2 和 IFNL3 的表达,NFIC1 过表达增强干扰素介导的 Jak-STAT 通路的激活。Jak-STAT 通路抑制剂 Filgotinib 或 Ruxolitinib 处理可逆转 NFIC1 过表达对 MCF-7 细胞迁移和侵袭的抑制作用。此外,我们发现 Jak-STAT 通路的两个靶基因 MX1 和 MX2 介导 MCF-7 细胞的迁移和侵袭。这些结果表明,NFIC1 通过干扰素介导的 Jak-STAT 通路激活抑制 MCF-7 细胞的迁移和侵袭,表明 Jak-STAT 通路可能是预防乳腺癌转移的潜在治疗靶点。
