Figure Lengend Snippet: The expression of F2/Rho, HMGB1/RAGE/p38MAPK/NF-κB signal pathway-related proteins increases in the lung tissues of rats simulated high-altitude hypoxia. (A) Western blot analysis was performed to examined the protein expression levels of F2, ROCK1, RhoA, HMGB1, RAGE, p38 MAPK and (NF-κB) p65 in the rat lung tissue. (B) Relative protein expression was normalized to that of the respective control, β-actin. (C-E) Immunohistochemistry of RAGE and HMGB1 in lung tissues of rats. The staining results of the images revealed that the expression of RAGE and HMGB1 in the lung tissues of rats exposed to hypoxia was significantly increased compared with that of the control rats. The left and right dark and bright images in each group is the comparison of the results before and after molecular staining. The positive results in the bright pictures refer to the immunostaining of HMGB1 and RAGE. * P<0.05 vs. the control group. F2, prothrombin; RAGE, receptor for advanced glycation end products; HMGB1, high mobility group protein-1; C, control; H, hypoxia.

Figure Lengend Snippet: The cells were randomly divided into four groups as follows: The control group, control + siRAGE group, hypoxia + siRAGE group and hypoxia group, and cultured according to the culture conditions (the concentration of siRAGE was 100 nM). (A) Western blot analysis was performed to examine the protein expression levels of RAGE in the different groups. (B) The relative protein expression gray scale statistics of RAGE. (C) Western blot analysis was performed to examine the protein expression levels of RAGE, HMGB1, p-p38, p-p65, HIF-1α and β-actin in NR8383 cells in the control, control + siRAGE, hypoxia + siRAGE and hypoxia groups.

Figure Lengend Snippet: Pre-treatment with SB203580 inhibits the activation of the NF-кB signaling pathway. NR8383 cells were pre-treated with SB203580 (10 µ M) for 1 h and then exposed to hypoxia for 24 h. Pre-treatment with SB203580 intercepted the phosphorylation of p65 protein.
