KEGG analysis indicated that T cell- or HCC-related items like “T-cell leukemia virus 1 infection”, “Hepatocellular carcinoma”, “T cell receptor signaling pathway”, “PD-L1 expression and PD-1 checkpoint pathway in cancer”, and “Th1 and Th2 cell differentiation” were up-regulated at RBPJ enrichment peaks (Figure 5C). The gene discussed is PDCD1; the disease is cancer.
