Exogenous GSH provided rat small-intestinal epithelial cells with significant protection against injury induced by t-butyl hydroperoxide or menadione. This protection was found to be dependent upon uptake of intact GSH. Uptake of GSH occurred by a Na+-dependent electrogenic system found in the basolateral membrane. Thus, rat small-intestinal epithelial cells can utilize plasma GSH to support intracellular detoxication systems that function in protection against chemically induced injury.
外源性谷胱甘肽(GSH)为大鼠小肠上皮细胞提供了显著的保护作用,使其免受叔丁基过氧化氢或甲萘醌诱导的损伤。这种保护作用依赖于完整GSH的摄取。GSH的摄取是通过位于基底外侧膜上的一种依赖钠离子的电驱动系统进行的。因此,大鼠小肠上皮细胞可以利用血浆中的GSH来支持细胞内的解毒系统,该系统在抵御化学诱导损伤中发挥作用。
