Annexin 1 (ANXA1) expression is associated with the malignant tumor phenotype, making it an attractive therapeutic target. However, little is known about the regulation of ANXA1 in non-small cell lung cancer (NSCLC).
We investigated the biological roles of ANXA1 in tumor growth, migration, and invasion, and explored the possibility of ANXA1 as a potential therapeutic target for the treatment of NSCLC.
Our findings revealed that ANXA1 enhanced nuclear factor (NF)-κB activation in NSCLC cells by interaction with inhibitor of NF-κB kinase complex subunit, IKKγ. We also found that NF-κB could negatively regulate microRNA (miR)-26a, and miR-26a was regulated through the ANXA1-NF-κB regulatory pathway. NF-κB activation negatively regulated by miR-26a was confirmed in NSCLC.
Together, these results provide evidence of the mechanisms of the ANXA1-NF-κB-miR-26a regulatory pathway in the invasion and migration in NSCLC.
膜联蛋白 1(ANXA1)的表达与恶性肿瘤表型相关,使其成为有吸引力的治疗靶点。然而,关于非小细胞肺癌(NSCLC)中 ANXA1 的调节知之甚少。
我们研究了 ANXA1 在肿瘤生长、迁移和侵袭中的生物学作用,并探讨了 ANXA1 作为治疗 NSCLC 的潜在治疗靶点的可能性。
我们的研究结果表明,ANXA1 通过与 NF-κB 激酶复合物亚单位 IKKγ 的相互作用,增强了 NSCLC 细胞中的核因子(NF)-κB 激活。我们还发现 NF-κB 可以负调控 microRNA(miR)-26a,并且 miR-26a 通过 ANXA1-NF-κB 调节途径进行调节。NF-κB 的激活被 miR-26a 负调控,这在 NSCLC 中得到了证实。
综上所述,这些结果为 ANXA1-NF-κB-miR-26a 调节途径在 NSCLC 侵袭和迁移中的机制提供了证据。
