Figure 4

Effect of MA and TBHQ on the PERK signaling pathway. (a) PERK signaling expression by western blot; (b) p-PERK/PERK in lungs in different groups; (c) p-eIF2α/eIF2α in different groups; (d) ATF4 protein expression in different groups. Values are expressed as mean ± SD (). , , compared with the control group; , , compared with the MA group. MA: methamphetamine; THBQ: tertiary butylhydroquinone.
