Protective Effects of Liposomal N-Acetylcysteine against Paraquat-Induced Cytotoxicity and Gene Expression
Figure 5
Effect of NAC or L-NAC pretreatment on IL-8 levels after PQ exposure. Cells pretreated for 4 h with control media or 5.0 mM NAC- (N) or L-NAC-containing media (L) were challenged with 0, 0.25, or 1.0 mM PQ for 4 h. Cell culture supernatants were collected immediately following challenge and concomitantly analyzed for IL-8 using the Bio-Plex suspension array system. Bars represent mean ± S.E.M. of 3 independent experiments. *denotes significant difference relative to cells with no pretreatment .
