Fig. 4From: Effects of chronic noise exposure on the microbiome-gut-brain axis in senescence-accelerated prone mice: implications for Alzheimer’s diseaseChronic noise exposure and aging diminish intestinal and brain endothelial tight junction protein expression in SAMP8 mice. a mRNA expression levels of the tight junction components in SAMP8 mouse intestine samples (n = 6). b Protein expression levels of the main tight junction components in SAMP8 mouse intestine samples (n = 4). c Protein expression levels of the main tight junction proteins in the hippocampus of SAMP8 mice (n = 4). GAPDH was used as a loading control. Data are shown as the mean ± standard deviation. HN high-intensity noise exposure, LN low-intensity noise exposureBack to article page
