According to ClueGO, the most involved KEGG pathways are cell cycle, focal adhesion, FoxO signaling, hepatitis B, insulin signaling, MAPK signaling, neurotrophin signaling, Rap1 signaling, T cell receptor signaling; three of these (focal adhesion, MAPK signaling, and neurotrophin signaling) were also identified through GeneTrail. Here, BDNF is linked to hepatitis A virus infection.
