From: 2-arachidonyl glycerol modulates astrocytic glutamine synthetase via p38 and ERK1/2 pathways
Effects of inhibition of MAPK on the phosphorylation of p38 (a) and ERK1/2 (b), and GS expression (a, b). Astrocytes were pretreated with SB203580 (a) or PD98059 (b) for 1 h and exposed to 1 μg/ml LPS for 2 h (a) or 12 h (b). The protein level of GS, p-p38 and p-ERK1/2 were measured, respectively (a, b). Error bars were ± SD. n = 3. *p < 0.05, **p < 0.01, and ***p < 0.001
