Briefly, seven KEGG pathways were detected, namely “MicroRNAs in cancer,” “Pathways in cancer,” “prostate cancer,” “Colorectal cancer,” “Central carbon metabolism in cancer,” “Breast cancer,” and “PD-L1 expression and PD-1 checkpoint pathway in cancer”, which are directly involved in cancer (Table 9, shown in underlined). The gene discussed is CD274; the disease is breast cancer.
