(A–C) GO analysis of mRNAs in the ceRNA network. x-axis reflects the gene count; y-axis reflects different GO terms. The column color reflects the P-value (−log10(P-value)): black represents the biggest value; blue represents the smallest value. (D) The node size reflects the gene count: the bigger the gene count, the bigger the node size. The node color reflects the P-value (−log10(P-value)): the bigger the −log10(P-value) value, the darker the node color.
