摘要:

文题释义:

肿瘤微环境是指肿瘤的发生、生长及转移与肿瘤细胞所处的内外环境有着密切关系,它不仅包括肿瘤所在组织的结构、功能和代谢,而且亦与肿瘤细胞自身的(核和胞质)内在环境有关。肿瘤细胞可以通过自分泌和旁分泌,改变和维持自身生存和发展的条件,促进肿瘤的生长和发展。

上皮间质转化:指上皮到间质细胞的转化,它赋予细胞转移和入侵的能力,包括干细胞特征、减少凋亡与衰老,和促进免疫抑制,不仅在发育过程中起着关键的作用,而且还参与组织愈合、器官纤维化和癌症发生等过程。

背景:Wnt/β-catenin信号通路在骨肉瘤的肿瘤发生和骨重建中起的关键作用,及其在血管生成和免疫监视中的意义,是转移性播散的2个关键机制。

目的文章就Wnt/β-catenin通路在骨肉瘤发生发展中的作用及其对特定微环境的调控进行综述。

方法检索2000年至2020年为止的PubMed数据库“Wnt/β-cateninbone tumors为英文检索词,得到Wnt/β-catenin通路与骨肿瘤关系的相关研究。

结果与结论典型的Wnt/β-catenin信号通路通过直接作用于骨肉瘤细胞和间接调节骨肉瘤细胞活性2种方式在骨肉瘤生长和转移过程中起着重要作用。Wnt/β-catenin通路也参与了骨肉瘤细胞对骨肿瘤微环境的劫持,促进细胞外基质的调节,使肿瘤细胞具有侵袭性,诱导肿瘤细胞的免疫耐受和血管生成,最终导致转移扩散的增加。另外,骨肉瘤细胞中典型Wnt信号通路的异常激活似乎与细胞增殖、上皮间质转化样过程的诱导、骨肉瘤促肿瘤细胞干细胞特性的获得以及转移扩散密切相关。

Abstract:

BACKGROUND: The Wnt/β-catenin signaling pathway plays a key role in osteosarcoma tumorigenesis and bone remodeling, and its roles in angiogenesis and immune surveillance are the two key mechanisms of metastatic dissemination.

OBJECTIVE: To review the role of Wnt/β-catenin pathway in the occurrence and development of osteosarcoma and its regulatory role in specific microenvironment.

METHODS: PubMed database was searched for relevant articles on the relationship between Wnt/β-catenin pathway and bone tumors using the search terms of “Wnt/β-catenin; bone tumors.” The search time for publications was from 2000 to 2020.

RESULTS AND CONCLUSION: The typical Wnt/β-catenin signaling pathway plays an important role in the growth and metastasis of osteosarcoma by directly acting on osteosarcoma cells and indirectly regulating cell activity in osteosarcoma. The Wnt/β-catenin pathway also participates in the hijacking of the bone tumor microenvironment by osteosarcoma cells, promotes the regulation of extracellular matrix, makes the tumor cells invasive, induces immune tolerance and angiogenesis in tumor cells, and eventually augments metastatic spread. In addition, the typical Wnt signaling pathway abnormally activated in osteosarcoma cells seems to be closely related to cell proliferation, induction of epithelial-mesenchymal transition-like processes, acquisition of osteosarcoma-promoting tumor cell stem cell characteristics, and metastatic spread.

Key words: Wnt/β-catenin, osteosarcoma, bone tumor microenvironment, treatment strategy, pathway, review
