Fig. 4From: Environmental noise stress disturbs commensal microbiota homeostasis and induces oxi-inflammmation and AD-like neuropathology through epithelial barrier disruption in the EOAD mouse modelEffects of chronic noise exposure on the status of oxidative stress in the intestine. a–e Antioxidant capacities in cecal contents (n = 5–6). f–k mRNA expression levels of key enzymes in GSH/GST pathways and NOX2/4 in colon tissue (n = 6). l Enzyme-linked immunosorbent assay analysis of Nrf2 content in colon tissue (n = 5–6). Data are presented as the mean ± standard deviation. *P < 0.05, **P < 0.01 vs. WT CON group; #P < 0.05, ##P < 0.01 vs. APP/PS1 CON group. §, exposure effect, P < 0.05; ¶, genotype effect, P < 0.05; ǂ, interaction effect, P < 0.05. CON, control groups; NOISE, noise-exposed groups; WT, wild-type mice; APP/PS1, APP/PS1 transgenic miceBack to article page
