骨肉瘤是最常见的原发性恶性骨肿瘤。然而,我们对其发病机制的分子机制的理解并不完整。研究表明,NK同源盒(NKX)基因的异常表达可能参与多种癌症的发生。这里,通过迁移筛选实验,我们发现一系列NKX基因抑制骨肉瘤细胞的迁移。在这些基因中,NKX2-2 是骨肉瘤的真正抑癌基因。 NKX2-2的过表达在体外降低骨肉瘤细胞的迁移、侵袭、增殖和集落形成,在体内抑制肿瘤生长和转移。此外,根据体外和体内研究的结果,NKX2-2的转录激活结构域对其肿瘤抑制功能很重要。从机制上讲,我们揭示了 NKX2-2 部分通过介导 COL5A2、PLAU、SEMA7A 和 S1PR1 基因的转录下调来发挥肿瘤抑制因子的作用。总之,我们对NKX2-2的研究揭示了骨肉瘤增殖和转移的新分子机制,可能为骨肉瘤提供一系列潜在的治疗靶点。
Osteosarcoma is the most common primary malignant bone tumor. However, our understanding of the molecular mechanism underlying its pathogenesis is incomplete. Studies have shown that aberrant expression of NK homeobox (NKX) genes may be involved in the oncogenesis of various cancers. Here, through migration screening assay, we found that a series of NKX genes inhibit the migration of osteosarcoma cells. Among these genes, NKX2-2 is a bona fide tumor suppressor for osteosarcoma. Overexpression of NKX2-2 decreases the migration, invasion, proliferation and colony formation of osteosarcoma cells in vitro and suppresses tumor growth and metastasis in vivo. Moreover, based on the results from both in vitro and in vivo studies, the transcriptional activation domain of NKX2-2 is important for its tumor suppressor function. Mechanistically, we revealed that NKX2-2 acts as a tumor suppressor partially by mediating the transcriptional downregulation of COL5A2, PLAU, SEMA7A and S1PR1 genes. In summary, our studies of NKX2-2 revealed new molecular mechanisms underlying osteosarcoma proliferation and metastasis and may provide a series of potential therapeutic targets for osteosarcoma.
