It is worth mentioning that pathways including p53 signaling,cellular senescence, human T-cell leukemia virus 1 infection, cell cycle (WP179), DNAreplication (WP466), miRNA regulation of DNA damage response (WP1530) and DNA damageresponse (WP707) only shared CCNB2 gene from the hub genes, whileAURKA was only detected in the gastric cancer network 1 (WP2361)pathway. This evidence concerns the gene CCNB2 and gastric cancer.
