Description | GRGDSPK acetate shows inhibitory activity against integrin-fibronectin binding and can be used in research on integrins in bone formation and resorption. |
In vitro | 通过测量孕龄Sprague-Dawley大鼠的顶骨组织中的钙含量和70 bonehnit面积,我们发现GRGDSPK(EMD 56574; RGD; 0.1-50 μM; 持续4天)以剂量依赖的方式抑制矿化作用。[1] 经GRGDSPK处理(10和50 μM; 4天)后,骨骼形态出现显著改变,特征为成骨细胞和矿化基质的组织结构遭到破坏。[1] 在含GRGDSPK肽段(RGD; 250 μM)的培养基中,整合素与纤维连接蛋白之间的结合被有效阻断,导致野生型细胞的细胞聚集体平均大小显著增加。[2] 添加GRGDSPK(250 μM)显著减少了野生型中胚层前体细胞的黏附力和所施加的工作量,指出这些前体细胞表达的整合素的参与,以及记录的对纤维连接蛋白的脱附参数的特异性。[2] GRGDSPK(含RGD,1.5 mM、1.0 mM 和 0.5 mM)及RGD修饰的肽段以1.5 mM、1.0 mM 和 0.5 mM 的浓度,削弱了牛卵母细胞的受精能力,导致精子细胞的裂解率以剂量依赖的方式减少。[3] |
