Fig. 2From: Interactions between Sirt1 and MAPKs regulate astrocyte activation induced by brain injury in vitro and in vivoThe expression of Sirt1 and p-ERK/p-JNK/p-p38 after IL-1β stimulation and brain injury. The expression of Sirt1 is reduced and p-ERK, p-JNK, and p-p38 are elevated significantly for the time indicated in vitro (a) and in vivo (b). n = 6/group, *P < 0.05 and **P < 0.01 vs. the control or sham groupBack to article page
