The enriched KEGG pathways of LCA, LCB, LCC, LCD, LCE, LCF, and LCG were also highly similar, all containing pathways such as MicroRNAs in cancer, human cytomegalovirus infection, MAPK signaling pathway, NF-kappa B signaling pathway, and PD-L1 expression and PD-1 checkpoint pathway in cancer. Here, CD274 is linked to cancer.
