Figure 5From: N-acetylcysteine prevents HIV gp 120-related damage of human cultured astrocytes: correlation with glutamine synthase dysfunctionThe effect of gp120 on glutamine synthase expression in human cultured astroglial cells. Incubation of astroglial cells with gp 120 (0.1, 1, 10 nM) for 24 hours dose-dependently reduced the GS expression as measured by western blotting analysis. Pre-treatment of 2 hours with NAC (5 mM) antagonized this effect. Blots are representative of 5 experiments. The columns represent the mean ± S.E.M %Back to article page
