PCDHGB7 and neoplasm: KEGG analysis showed that PCDHGB7 was associated with typical tumor proliferation pathways including phosphatidylinositol 3’-kinase (PI3K)-Akt signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, Janus kinase/signal transducers, and activators of transcription (JAK-stat) signaling pathway.
