半乳糖凝集素-3介导细胞表面糖蛋白聚集、交联和晶格形成。在癌症生物学中,据报道半乳糖凝集素-3在导致肿瘤栓塞和存活的聚集过程中发挥作用。在这里,我们表明,乳糖功能化的树枝状大分子与半乳糖凝集素-3以多价的方式相互作用,形成聚集体。的glycodendrimer-半乳糖凝集素聚集体的特征在于通过动态光散射和荧光显微镜方法,并被发现是离散的颗粒,随着树枝状聚合物一代的增加,在尺寸上增加。这些结果表明,半乳糖凝集素-3的成核聚集可以通过成核聚合物来调节,并提供了提高对糖结合蛋白的结合和功能的一般理解的见解。
Galectin-3 meditates cell surface glycoprotein clustering, cross linking, and lattice formation. In cancer biology, galectin-3 has been reported to play a role in aggregation processes that lead to tumor embolization and survival. Here, we show that lactose-functionalized dendrimers interact with galectin-3 in a multivalent fashion to form aggregates. The glycodendrimer–galectin aggregates were characterized by dynamic light scattering and fluorescence microscopy methodologies and were found to be discrete particles that increased in size as the dendrimer generation was increased. These results show that nucleated aggregation of galectin-3 can be regulated by the nucleating polymer and provide insights that improve the general understanding of the binding and function of sugar-binding proteins.
