一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Eeyarestatin I(EerI [1])是内质网相关性降解(ERAD)抑制剂,扰乱内质网(ER)体内平衡,并具有类似于Bortezomib的抗肿瘤活性。ESI诱导JEKO-1细胞死亡,IC50值为4±1.2 μM[2]。ESI也是蛋白质转运的有效抑制剂。ESI对ER转运和N-糖基化的体外IC50值约为70 μM[1]。
ERAD途径可以清除错误折叠的ER蛋白质,及时从ER中清理错误折叠的蛋白,能维持ER稳态[2]。N-糖基化是最常见的和多功能的蛋白质修饰,作用于Asn-Xaa-Ser/Thr sequon天冬酰胺的β酰胺键上。ER甘露糖苷酶I可能引发折叠不当的糖蛋白靶向降解[4]。
在A9细胞中,与Me2SO相比,EerI使多泛素化的MHC I类分子重链(HC)蛋白在细胞质中积累。与MG132相比, EerI导致细胞生成极少量的去泛素化去糖基化HC分子,尽管此数量与积累的多泛素化HC数量接近[5]。在H1299细胞中,与对照相比,连续24小时给予EerI显著(P< 0.01)减少细胞增殖(24.0%)[6]。
在无胸腺裸鼠中,皮下注射Matrigel与H1299细胞(8×106)后的第2天和第6天给予10 μM的EerI,与DMSO对照组相比,EerI显著减少肿瘤的生长[6]。
