Integrins are transmembrane glycoproteins that consist of an α and a β subunit. Specific integrin heterodimers preferentially bind to distinct extracellular matrix (ECM) proteins to affect the characteristics of cells or the components of the ECM. Among the different integrins, β1 and β3 integrins serve essential roles in the progression of different cancer-associated processes, including the initiation, proliferation, survival, migration and invasion. Furthermore, previous studies have revealed a ratio between these two integrins in cancer cells, which also demonstrated that the functions of these two integrins are paradoxical. This indicated that the proliferation and metastasis of cancer cells are not always parallel and may be considered independently maintained. Additionally, the present review may assist in understanding certain aspects of cancer, and in making clinical decisions in a novel and more comprehensive manner.
整合素是由α和β亚基组成的跨膜糖蛋白。特定的整合素异二聚体优先结合不同的细胞外基质(ECM)蛋白,以影响细胞的特性或ECM的成分。在不同的整合素中,β1和β3整合素在不同的癌症相关过程(包括起始、增殖、存活、迁移和侵袭)的进展中发挥着重要作用。此外,先前的研究揭示了癌细胞中这两种整合素之间的比例,这也表明这两种整合素的功能是相互矛盾的。这表明癌细胞的增殖和转移并不总是平行的,可能被认为是独立维持的。此外,本综述可能有助于理解癌症的某些方面,并以新颖、更全面的方式做出临床决策。
