我们已经从大脑皮层细胞表面纯化并鉴定了一种糖肽,其抑制正常细胞但不转化细胞的细胞蛋白质合成。数据相关的能力C3H纤维肉瘤1316细胞,以避免抑制剂的活性与降低细胞水平的神经节苷脂GM1。当1316细胞在神经节苷脂掺入细胞的条件下与GM 1孵育时,细胞变得对抑制剂敏感,用神经酰胺进行的类似实验导致1316敏感性没有变化。此外,当1316细胞与GM 1孵育18小时,他们显然代谢GM 1简单的神经节苷脂,失去了对糖肽抑制剂的敏感性。
We have purified and characterized a glycopeptide from surfaces of brain cortex cells that inhibits cellular protein synthesis in normal but not transformed cells. Data are presented that correlate the ability of C3H fibrosarcoma 1316 cells to avoid the inhibitor's activity with a reduced cellular level of the ganglioside GM1. When 1316 cells were incubated with GM1 under conditions in which the ganglioside is incorporated into the cells, the cells became sensitive to the inhibitor, Similar experiments with ceramide resulted in no change in 1316 sensitivity. In addition, when 1316 cells were incubated with GM1 for 18 h, they apparently metabolized GM1 to simpler gangliosides and lost their sensitivity to the glycopeptide inhibitor.
