Fig. 3From: Gut derived-endotoxin contributes to inflammation in severe ischemic acute kidney injuryNorfloxacin pretreatment reduces kidney TLR4 protein expression and renal proinflammatory mediators production. (a) Immunohistological staining of TLR4 in the kidney. (b) TLR4/GAPDH protein expression on densitometry. mRNA and protein levels of TNF-α (c, f), IL-6 (d, g) and MCP-1 (e, h) were measured in kidney hemogenates. Data are presented as mean ± SD. One-way ANOVA followed by Bonferroni multiple comparison test was used in all graphs (n = 5 per group). *P < 0.05, **P < 0.01, ***P < 0.001. (Original blots ‘BMC Additional file 1)Back to article page
