AKT1 and Epstein-Barr virus infection: As for some other pathways associated with viral infection that were also enriched, such as hepatocellular carcinoma, Kaposi sarcoma-associated herpesvirus infection, Epstein-Barr virus infection, and human papillomavirus infection, we speculate that this is due to the fact that many of the genes enriched in these pathways overlap with genes in the PI3K/AKT, MAPK, cell cycle, and apoptosis pathways.
