The 14 most significantly enriched signalling pathways were Cytoplasmic Ribosomal Proteins, Metapathway biotransformation Phase I and II, TCA Cycle, Valproic acid pathway, Gastric Cancer Network 2, G1 to S cell cycle control, DNA IR-Double Strand Breaks (DSBs), and cellular response via ATM, DNA Mismatch Repair, Hippo-YAP signalling pathway, DNA Replication, DNA IR-damage and cellular response via ATR, Photodynamic therapy-induced NF-kB survival signalling, and Cell cycle and Retinoblastoma Gene in Cancer (Figure 6A, FDR < 0.05). This evidence concerns the gene ATM and gastric cancer.
