PPI network of (A) All DE-miRNA, B down-regulated DE-miRNA and C up-regulated DE-miRNA target genes. The top 25 nodes (genes) in terms of connectivity are selected for the graph, and the size of the circle represents the level of connectivity, with larger circles indicating higher connectivityBack to article page
