The results from KEGG pathway enrichment analysis demonstrated that common DEGs were significantly involved in transcriptional misregulation in cancer, parathyroid hormone synthesis secretion and action, regulating pluripotency of stem cells, MAPK signaling, Ras signaling pathways, EGFR tyrosine kinase inhibitor resistance, prostate cancer, viral protein interaction with cytokine and cytokine receptor, FoxO adhesion molecules, gastric cancer, proteoglycans in cancer, and endocytosis (Figure 2(b)). The gene discussed is PTH; the disease is gastric cancer.
