Figure Lengend Snippet: Figure 6. Network-based analysis of interaction network corresponding to candidate genes. (A) The node degree distribution of PPI network. The number of genes is plotted as a function of their degree reflecting a power-law like distribution. The red line corresponds to a power-law distribution. (B) Sub-network of candidate genes. The large-sized black-colored nodes represent the candidate genes (ABCC1, ABCG2, CERK, MMP-2, MMP-9, and SPHK1), while the small gray color nodes represent the corresponding interactor genes. Interactions are represented in gray color and the depth of color represents the strength of correlations. (C) Shortest path lengths among candidate genes. Heatmap of shortest path length among the candidate genes, where the values represent the number of shortest paths between any pair.

Figure Lengend Snippet: (A,B) Western blot analysis of Sphk1 and S1PR1 in the cerebral cortex and hippocampus of rats at 24h after MCAO. (C,D) Representative photographs represented the expression of CD62P in the cerebral cortex and hippocampus at 24h reperfusion after MCAO. The positive products were brown granules after immunostaining, which was remarkably increased followed MCAO and was significantly decreased after treatment with DSCXQ. Representative images of Sphk1 and S1PR1 were presented, and the protein levels were expressed as a ratio of the β-tubulin levels ( n = 3). Data were expressed with mean values ± standard deviation (SD). ## p < 0.01 vs. Sham group, ** p < 0.01 * p < 0.05 vs. Model group.
