整合素β3由于其在新生血管中的表达而被视为癌症治疗的关键抗血管生成靶点,但它在该过程中发挥的作用是复杂的;它是促血管生成还是抗血管生成取决于其表达的背景。为了准确理解β3在调节内皮细胞中整合素粘附复合物中的作用,我们通过质谱法表征了β3依赖性粘附体。我们发现,这种细胞类型中β3-整合素的缺失导致控制细胞迁移的微管行为发生变化。β3整合素通过Rcc 2/Anxa 2驱动的活性Rac 1定位控制调节内皮细胞中微管的稳定性。我们的研究结果表明,当β3-整联蛋白水平降低时,体外和体内的血管生成过程对微管靶向剂更敏感。
Integrin β3 is seen as a key anti‐angiogenic target for cancer treatment due to its expression on neovasculature, but the role it plays in the process is complex; whether it is pro‐ or anti‐angiogenic depends on the context in which it is expressed. To understand precisely β3's role in regulating integrin adhesion complexes in endothelial cells, we characterised, by mass spectrometry, the β3‐dependent adhesome. We show that depletion of β3‐integrin in this cell type leads to changes in microtubule behaviour that control cell migration. β3‐integrin regulates microtubule stability in endothelial cells through Rcc2/Anxa2‐driven control of active Rac1 localisation. Our findings reveal that angiogenic processes, both in vitro and in vivo, are more sensitive to microtubule targeting agents when β3‐integrin levels are reduced.
