Adhesion of breast cancer cells is supported by various integrins. Cell adhesion is critical for maintenance of both three-dimensional and normal function of these tissues. Several integrins have been shown to have higher expression levels in metastatic cancers and have been implicated in degrading basement membrane by interacting with proteolytic enzymes. This suggests that a group of integrins plays an important role in migration and invasion through the remodeling of the extracellular matrix. In this review, we highlight recent advances in our understanding of how integrins regulate breast cancer through modulation of the actin cytoskeleton and the mechanisms that regulate this process. Also, we highlight the importance of integrin-binding proteins in cell migration and mechanisms that operate in invasive cells, during breast cancer progression.
乳腺癌细胞的黏附受到各种整合素的支持。细胞黏附对于维持这些组织的三维和正常功能至关重要。已经证明,一些整合素在转移性癌症中表达水平更高,并通过与蛋白水解酶相互作用来降解基底膜。这表明一组整合素通过重塑细胞外基质在迁移和侵袭中发挥重要作用。在这篇综述中,我们强调了最近在整合素通过调节肌动蛋白细胞骨架来调节乳腺癌以及调节这一过程的机制方面的理解进展。此外,我们还强调了整合素结合蛋白在乳腺癌进展过程中细胞迁移和侵袭细胞中作用机制的重要性。
