Blocking the formation of GSH with the addition of BSO (1 mM for 24 h) towards the tradition medium reduced the cellular content material of GSH by 70% (Fig. 5). This treatment also reduced the basal efflux (70% lower in comparison to culturing without BSO) and efflux of GSH activated by omission of extracellular Ca2+ (85% lower in comparison to cells cultured without BSO) (Fig. 4a, b). The result of BSO on basal efflux was selective for GSH, i.e. the efflux of additional proteins was unaffected. Treatment with BSO triggered no modification in efflux activated by omission of Ca2+ for phosphoethanolamine or taurine (not really demonstrated) but decreased that of glutamate (Fig. 4b). The mobile content material of phosphoethanolamine was unchanged but that of glutamate improved by BSO treatment (Fig. 5).
