Expression and interactions of the PRGs. A The expression of 49 PRGs in GBM and normal brain tissues. The upper and lower ends of the boxes represented the interquartile range of values. The lines in the boxes represented the median value. B The PPI network showing the interactions of differentially expressed PRGs (minimum required interaction score = 0.4). The color depth of the node represented the degree. C The correlation network of differentially expressed PRGs (red line: positive correlation, blue line: negative correlation. The depth of color reflected the intensity of correlation)
