The most significant KEGG pathways were “PD-L1 expression and PD-1 checkpoint pathway in cancer” (KEGG:05235), “GnRH signaling pathway” (KEGG:04912), “T cell receptor signaling pathway” (KEGG:04660), “Sphingolipid signaling pathway” (KEGG:04071), and “AMPK signaling pathway” (KEGG:04152). Here, GNRH1 is linked to cancer.
