Effect of glycyrrhizin on HMGB1 protein expression. (A) Representative western blot bands of HMGB1 with intracellular total protein, nucleus and cytoplasmic protein isolation. Expression levels were normalized to β-actin. The expressions of intracellular and cytoplasmic HMGB1 were significantly increased in the PC-AKI group compared to the controls, and were significantly reduced in the PC-AKI with glycyrrhizin group. On the other hand, the expression of nucleus HMGB1 in PC-AKI group significantly reduced compared to the control, but was significantly increased PC-AKI with glycyrrhizin group. The β-actin was used as a cytoplasmic and intracellular marker and LaminB1 as a nuclear marker. (B) The serum HMGB1 measured by ELISA was significantly higher in the PC-AKI group compared to the controls, but was significantly lower in the PC-AKI with glycyrrhizin group. Images of blots were cropped. Full-length blots are presented in Supplementary Figure 1. Results were expressed as means ± SEMs. N = 8 for each group. Statistical significance: *P < 0.05, ***P < 0.001 Con vs PC-AKI and Con vs PC-AKI + GL, ##P < 0.01 and ###P < 0.001 PC-AKI vs GL + PC-AKI. Abbreviation: PC-AKI, post-contrast acute kidney injury; GL, glycyrrhizin.
