Additionally, KEGG enrichment analysis demonstrated significant correlations between the differentially expressed mRNAs and various cancer-related pathways, including pathway in cancer, gastric cancer, breast cancer, colorectal cancer, human papillomavirus infection, proteoglycans in cancer, signaling pathways regulating pluripotency of stem cells, mTOR signaling pathway, chemokine signaling pathway, non-small-cell lung cancer, and others (Fig. 6D). This evidence concerns the gene MTOR and gastric cancer.
