RGDS肽含有RGD基序,该基序是整合素的拮抗剂。
RGDS peptide contains the RGD motif which is an antagonist of integrin .
整合素是细胞表面受体,其识别存在于各种细胞外基质蛋白中的RGD基序,如纤连蛋白、玻璃体凝集素、层粘连蛋白、纤维蛋白原、von Willebrand因子、骨桥蛋白、血小板反应蛋白和胶原以及崩解蛋白中。整合素的激活触发不同的信号,调节细胞粘附、迁移、存活、凋亡以及血管生成、血栓形成和骨质疏松等过程。
Integrins are cell-surface receptors that recognize RGD motifs present in various extracellular matrix proteins such as fibronectin, vitronectin, laminin, fibrinogen, von Willebrand factor, osteopontin, thrombospondin, and collagen as well as in disintegrins. Integrins activation triggers different signals regulating cell adhesion, migration, survival, apoptosis as well as processes such as angiogenesis, thrombosis and osteoporosis .
在SK-MEL-110细胞中,500μg/ml的RGDS显著抑制人成纤维细胞生长因子-2(FGF-2)诱导的黑色素瘤细胞增殖。此外,RGDS处理(48小时,500μg/ml)使亚G1期细胞的百分比从3%(单独使用FGF-2)增加到13.2%(使用FGF-2和RGDS),表明在存在FGF-2的情况下,RGDS可能诱导黑色素瘤细胞凋亡。
In SK-MEL-110 cells, RGDS at 500 μg/ml significantly inhibited melanoma cells proliferation induced by human fibroblast growth factor-2 (FGF-2). Furthermore, RGDS treatment (48 h, 500 μg/ml) increased the percentage of cells in sub-G1-phase from 3% (with FGF-2 alone) to 13.2% (with FGF-2 and RGDS), indicating that RGDS might induce apoptosis in melanoma cells, in the presence of FGF-2
