脑信号蛋白(Semas)是传统轴突引导分子的一个大家族。通过与它们的受体丛蛋白和神经纤毛蛋白的相互作用,Sema在不断增长的各种生物系统中发挥着关键作用。本文就其在调节血管发育中的作用作一综述。此外,在过去几年中,许多研究结果表明,Sema及其受体在调节癌症进展和肿瘤血管生成中发挥着至关重要的作用。特别地,Sema通过直接影响癌细胞的行为或间接地通过调节肿瘤微环境中的血管生成和其他细胞类型的功能(即,炎性细胞和成纤维细胞)。一些Sema可以激活或抑制肿瘤进展和血管生成,而另一些则可能具有相反的作用,这取决于特定的翻译后修饰。在这里,我们还将讨论Sema及其受体复合物对癌症进展的各种生物学效应以及它们对肿瘤微环境的影响。
Semaphorins (Semas) are a large family of traditional axon guidance molecules. Through interactions with their receptors, Plexins and Neuropilins, Semas play critical roles in a continuously growing list of diverse biological systems. In this review, we focus on their function in regulating vascular development. In addition, over the past few years a number of findings have shown the crucial role that Semas and their receptors play in the regulation of cancer progression and tumour angiogenesis. In particular, Semas control tumour progression by directly influencing the behavior of cancer cells or, indirectly, by modulating angiogenesis and the function of other cell types in the tumor microenvironment (i.e., inflammatory cells and fibroblasts). Some Semas can activate or inhibit tumor progression and angiogenesis, while others may have the opposite effect depending on specific post-translational modifications. Here we will also discuss the diverse biological effects of Semas and their receptor complexes on cancer progression as well as their impact on the tumor microenvironment.
